Software Engineer

About PostHog We're shipping every product that companies need to run their business from their first day, to the day they IPO, and beyond. The operating system for folks who build software. We started with open-source product analytics, launched out of Y Combinator's W20 cohort. We've since shipped more than a dozen products, including: A built-in data warehouse, so users can query product and customer data together using custom SQL insights. A customer data platform, so they can send their data wherever they need with ease. PostHog AI, an AI-powered analyst that answers product questions, helps users find useful session recordings, and writes custom SQL queries. Next on the roadmap are CRM, messaging, revenue analytics, and support products. When we say every product that companies need to run their business, we really mean it! We are: Product-led. More than 100,000 companies have installed PostHog, mostly driven by word-of-mouth. We have intensely strong product-market fit. Default alive. Revenue is growing 10% MoM on average, and we're very efficient. We raise money to push ambition and grow faster, not to keep the lights on. Well-funded. We've raised more than $100m from some of the world's top investors. We're set up for a long, ambitious journey. We're focused on building an awesome product for end users, hiring exceptional teammates, shipping fast, and being as weird as possible. Things we care about Transparency: Everyone can read about our roadmap, how we pay (or even let go of) people, our strategy, and how we work, in our public company handbook. Internally, we share revenue, notes and slides from board meetings, and fundraising plans, so everyone has the context they need to make good decisions. Autonomy: We donâ't tell anyone what to do. Everyone chooses what to work on next based on what's going to have the biggest impact on our customers, and what they find interesting and motivating to work on. Engineers lead product teams and make product decisions. Teams are flexible and easy to change when needed. Shipping fast: Why not now? We want to build a lot of products; we can't do that shipping at a normal pace. We've built the company around small teams â- autonomous, highly-efficient groups of cracked engineers who can outship much larger companies because they own their products end-to-end. Time for building: Nothing gets shipped in a meeting. We're a natively remote company. We default to async communication â- PRs > Issues > Slack. Tuesdays and Thursdays are meeting-free days, and we prioritize heads down building time over perfect coordination. This will be the most productive job you've ever had. Ambition: We want to solve big problems. We strongly believe that aiming for the best possible upside, and sometimes missing, is better than never trying. We're optimistic about what's possible and our ability to get there. Being weird: Weird means redesigning an already world-class website for the 5th time. It means shipping literally every product that relates to customer data. It means building an objectively unnecessary developer toy with dubious shareholder value. Doing weird stuff is a competitive advantage. And it's fun. Who we're looking for We're hiring for a range of roles here. What you end up working on will depend on your exact skillset and preferences, so choose your own adventure. In general we seek Product Engineers who are: Enthusiastic drivers. We need proactive people that can fully own projects and get them done, and know to get help when needed. This is what being a product engineer is all about. "Are we there yet?" is the wrong question. Optimistic problem solvers. Things get hard here sometimes â- whether it's scaling, shipping complex products, handling a stream of support requests, or trying to ship something that touches multiple teams. We need people who won't get disheartened, and will collaborate, iterate, and ship their way out of anything. Grown ups. Weâ're an international bunch of weirdos, but one thing unites us: everyone is kind, considerate, and professional towards each other. This isn't about age or experience, it's about being low-ego, flexible, and respectful. Genuine builders. PostHog is full of people who just love building stuff, people who would still be building software even if there wasn't a paycheck at the end. If this sounds like you, we should talk. Right now, we are also looking for: IAM specialist: Youâ'll design and ship core features like SAML support, new identity providers, and even our own IAM system. Start with internal tooling, then roll them out to customers. Tell us how youâ'd make these systems so solid that other teams can build on them without hesitation. What you'll be doing Owning products and features from beginning to end. This means originating ideas based on your intuition, talking to users, and understanding our strategy and goals. It means testing MVPs in production with real users. It means iterating on their feedback, owning pricing, and ensuring the ongoing success of your work. Collaborating with design (when necessary). Product engineers at PostHog are full stack, so we expect you to ship and own the basic UX of your work using our design system. From there, it's up to you to decide when to collaborate with our design team to iterate and polish the experience. Talking to users. Good product engineers read feedback from users and iterate quickly. Great product engineers have users they're friendly with, talk with them frequently, bounce ideas off them, and iterate with them when they ship new things. Doing support. Every week, one person in each engineering team is designated the Support hero. Their job is to investigate and resolve issues reported by customers for their product. Giving users support from real engineers, and shipping fixes and improvements in real-time, is one of the best ways to spark joy in users. This role will also include some on-call time, too. Writing docs. We have a content team that will collaborate with you on reviewing, polishing, and improving your documentation, but the best person to document a new feature is the person who built it. Requirements Full-stack experience with relevant technologies â- e.g. Python or similar, React or similar, something to do with big data is a bonus. Experience taking a project from 0 to 1. You might have led a project, been a founder previously, or built an impressive side project. Strong writing skills. We document everything, most of it publicly. The ability to communicate your ideas and make persuasive arguments is essential. Nice to have Have worked at a high-growth SaaS company before. Extensive knowledge of Django and/or TypeScript-based React. Experience building AI-native products, or integrating AI into existing software. If you have a disability, please let us know if there's any way we can make the interview process better for you - we're happy to accommodate!

What is Loancrate? We started Loancrate to make home-buying simpler and less expensive for lenders and borrowers (us!). Today, mortgage lenders are stuck running their companies on software products built 20 years ago. These products are slow, unstable and don't lead to material improvements in efficiency. When using these systems, the average human cost to originate a loan is still over $11,000. Loancrate builds AI native tooling to automate mortgage workflows. Our ultimate goal is fully automated origination, which has the potential to save lenders over $16B in operating expense per year. Since starting in 2020, our remote team has enabled our customers to power >$85 billion in new home loans. We are a group of people excited to tackle the complexity of the home-lending industry. We care about collaboration, very open communication covering the good & the bad so that we learn from our decisions quickly, and ultimately having fun while we're building. You'll fit in well if you like diving deep quickly! The Opportunity Our dreams are big and we have much to build! We're looking for senior software engineers to help lead our team in powering the future of home buying in the US (which could entail managing a majority of US home loans every year '— financial assets worth trillions of dollars). We are excited to offer competitive salary and equity for this role. What To Expect As an engineer at Loancrate, you'll continue our team tradition by shipping code to production on your first day! Following that, within your first month, you'll dive into your first mission-critical project, such as... Architecting, building, and launching complex, multi-step AI agents that our customers use to digitize their ops workflows and save millions of dollars per year. Integrating with 3rd-party providers of lending services APIs to generate documents/disclosures, produce automated underwriting results, or prevent fraud. Architecting, building, and launching the next generation of our job processing infrastructure on AWS to make Loancrate's back end more observable and reliable. Tech Stack Nearly all of our code is written in TypeScript. We use React on the frontend, Node/Express on the backend (running inside Docker), GraphQL/Apollo on both sides, and Postgres as our database. We use AWS (ECS, RDS, ElastiCache, Kafka, ElasticSearch, and more) and manage all of our infrastructure with Terraform. We believe that high engineering velocity drives high product velocity (and, in turn, our success as a company ). Keeping this in mind, we've invested heavily in creating a great developer experience that enables engineers to ship fast. Some highlights of our stack: ' End-to-End Type Safety - We generate TypeScript types from our Postgres and GraphQL schemas so that when we change our database schema we see type errors in any incompatible frontend React components. Full-Stack Code Sharing - Our build tooling supports seamless sharing of TypeScript files between the client, server, and other packages in our mono-repo so that we never have to define functions or configuration values twice. Reproducible Infrastructure - We've used Terraform to manage 100% of our infrastructure since day 1 and have configured our CI pipeline to automatically deploy temporary staging environments for every pull request. We use these per-PR environments to get feedback from teammates and test any infrastructure changes using infrastructure that's identical to production. First Class Testing Utilities - We have a comprehensive library of utilities that mock production-like data and feed automated end-to-end, integration, and performance tests. Our wide-ranging test suite allows us to move fast while maintaining nearly perfect uptime. Preferred Skills and Background (It's okay not to have all of these things - these are just some skills we are excited about!) Familiarity with modern AI product development lifecycles (evals, experiment design, dataset curation, etc). We don't just build AI chat bots. We wrangle non-deterministic LLMs into reliable mission-critical systems. A constant and keen eye for security risks '— we store and display some of people's most sensitive personal data and need to keep it safe! A desire to be product-oriented, from thinking through the product implications of what you're building to contributing your unique ideas of how to improve the product. Ability to develop readable, maintainable, and effective software architecture patterns that support use of our product by various enterprise customers (each with thousands of employees and their own methods for running their companies). ' Excitement to mentor less senior engineers in both hard and soft skills. SRE-oriented mindset for developing infrastructure that's reliable, observable, and requires minimal toil to maintain. Experience scaling high-throughput distributed systems in the cloud. Bonus points if you're experienced with infrastructure-as-code solutions like Terraform or CloudFormation! Ability to develop full-stack web app features from design through deployment. Experience designing and scaling complex relational DB schemas, as well as figuring out performant ways to store, retrieve, and update such data. Home loans have thousands of data fields .

I've been building data-heavy mobile apps lately and spent way too much time evaluating table libraries. The React ecosystem has some solid options, but they're wildly different in approach. Let me break down what I've learned from actually shipping these in production.

TanStack Table (React Table v8): The Headless Powerhouse

TanStack Table is what React Table became after v7. It's completely headless, meaning zero UI components included. At first this felt like extra work, but honestly? It's perfect for mobile-first development where you need total control over rendering.

The core philosophy here is that TanStack handles the state management and logic while you handle every pixel of the UI. This makes it incredibly flexible but requires more initial setup.

The API is hook-based and composable. Want sorting? Add getSortedRowModel(). Need filtering? Toss in getFilteredRowModel(). I've found this modular approach keeps bundle sizes reasonable - you only ship what you actually use.

The mobile catch: On smaller screens, traditional tables suck. With TanStack's headless approach, I can easily switch to card layouts or accordions based on viewport width without fighting against built-in styles. The same table logic works whether I'm rendering a desktop grid or mobile cards.

Performance-wise, it handles 10k+ rows without breaking a sweat if you enable virtualization. The column pinning feature is surprisingly smooth even on mid-range Android devices.

AG Grid is what you reach for when your PM says "we need Excel but in the browser." It's massive, feature-complete, and honestly overkill for most mobile apps. But sometimes you need that firepower.

The free community version is already packed with features. The enterprise version adds stuff like row grouping, aggregation, and server-side operations that become essential at scale.

Here's the thing about AG Grid on mobile: it's not really built for it. The default experience on a phone is pretty rough. You can make it work with custom cell renderers and responsive column definitions, but you're fighting the library's desktop-first assumptions.

Where AG Grid shines is when you have power users who need to manipulate large datasets. The Excel-like filtering and sorting is incredibly powerful. I used it for an admin dashboard where users needed to export filtered data to CSV - that worked beautifully.

Bundle size is the elephant in the room. The community version adds ~150KB gzipped to your bundle. Enterprise is even larger. For mobile-first apps, that's a tough sell unless you really need those features.

React Data Grid: The Modern Middle Ground

React Data Grid from Adazzle (formerly known as react-data-grid) hit a sweet spot for me recently. It's less opinionated than AG Grid but more batteries-included than TanStack Table.

The built-in row selection, inline editing, and column resizing work out of the box. No configuration hell. The frozen columns feature is genuinely useful when you need to keep an identifier visible while scrolling horizontally.

Performance is solid up to about 5k rows without virtualization. Beyond that, you'll want to implement pagination or infinite scroll. The library uses CSS Grid internally which makes the rendering pretty snappy.

Mobile support is decent but not amazing. The touch interactions work, but you'll need custom CSS to make it truly mobile-friendly. I ended up hiding certain columns on mobile and adding a details modal for the full data.

Material React Table: When You Need MUI Integration

If you're already using Material-UI, Material React Table (MRT) is worth considering. It's built on top of TanStack Table but adds MUI components and a bunch of features out of the box.

MRT gives you a ton of features with minimal config: global search, column filters, density toggle, fullscreen mode. The MUI integration means everything looks consistent with your existing design system.

The downside? Bundle size is hefty since you're pulling in both TanStack Table and MUI components. I measured around 200KB gzipped for a basic table. That's a lot for mobile users on slow connections.

The mobile story here depends entirely on how well MUI's responsive components work for your use case. The built-in density toggle helps - switching to compact mode makes tables more usable on smaller screens.

For mobile-first apps, I default to TanStack Table. The headless approach lets me build exactly what I need without fighting against desktop-centric defaults. Yeah, it takes longer to set up initially, but the flexibility is worth it when you need to switch between table and card layouts.

For admin dashboards or internal tools where users are on desktop, AG Grid is hard to beat if budget allows for the enterprise license. The feature set is unmatched.

React Data Grid hits a nice balance for projects that need something quick but customizable. I used it for a recent project where we needed inline editing and it saved days of development time.

Material React Table makes sense if you're already deep in the MUI ecosystem and need tables that match your existing design system. Just watch that bundle size.

The real trick is matching the library to your actual requirements. Don't reach for AG Grid if you just need to display 50 rows with basic sorting. And don't torture yourself with a fully custom TanStack implementation if React Data Grid gives you 90% of what you need out of the box.
