UX Engineer

About this role

ABOUT POSTHOG

Product development used to mean manually writing code, running analysis, diagnosing bugs, and rolling out changes using dozens of tools.

PostHog is the only platform that acts like a co-pilot for you (and your AI agents) to do it all – autonomously.

We started with open-source product analytics, launched out of Y Combinator's W20 cohort https://posthog.com/handbook/story. We've since shipped more than a dozen products https://posthog.com/products, including:

- PostHog Code https://posthog.com/code, the only AI devtool that understands your product, not just your codebase.

- A built-in data warehouse https://posthog.com/docs/data-warehouse, so users can query product and customer data together using custom SQL insights.

- PostHog AI https://posthog.com/ai, an AI-powered analyst that answers product questions, helps users find useful session recordings, and writes custom SQL queries.

We are:

1. Product-led. More than 450,000 organizations have installed PostHog, mostly driven by word-of-mouth. We have intensely strong product-market fit.

2. Default alive https://paulgraham.com/aord.html. Revenue is growing incredibly quickly, and we're very efficient. We raise money to push ambition and grow faster, not to keep the lights on.

3. Well-funded. We've raised more than $180m 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 https://posthog.com/deskhog.

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 https://posthog.com/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 don’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 https://posthog.com/handbook/wide-company and make product decisions https://posthog.com/handbook/which-products. Teams are flexible and easy to change when needed.

- Shipping fast: Why not now? https://posthog.com/handbook/values#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 – autonomous, highly-efficient groups of cracked engineers https://posthog.com/founders/cracked-manifesto 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 – PRs > Issues > Slack. Tuesdays and Thursdays are meeting-free days https://posthog.com/handbook/company/culture#were-on-the-makers-schedule, 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 https://posthog.com/deskhog with dubious shareholder value. Doing weird stuff is a competitive advantage. And it's fun.

WHO WE'RE LOOKING FOR

The Platform UX team https://posthog.com/teams/platform-ux helps developers develop better products for developers by creating a UX that people won’t forget. We’re a small team where you get to work with our own self proclaimed beacon of user-focused-light, Adam Leith https://posthog.com/community/profiles/32193

We are looking for a rare breed: a builder who sits at the exact intersection of pixel-perfect design and high-velocity engineering. You aren't just a "coder". You are a product owner who uses the latest tools to ship ambitious features faster than most teams think possible.

You are someone who speaks ‘Designer intuition’, understands typography, whitespace, visual hierarchy, and color theory. You look at a Figma file and see why a 4px shift in padding matters, and you speak Developer Logic: understanding the DOM, component lifecycles, and performance constraints. You don't just build a button; you build a reusable, accessible, and performant button component.

We need someone with "keen eyes" who catches the small issues others miss and treats every interaction as an opportunity to delight a user. We care about how people interact with our product, and as a result we have a high bar for quality and a low tolerance for friction. You don't wait for a 50-page spec; you grab a rough idea, design the solution, and ship the code.

The TL;DR: We’re looking for someone with elite frontend skills, a refined design eye, an obsession with speed, and you know how to leverage AI (Claude, Cursor, etc.) to punch way above your weight class.

WHAT YOU'LL BE DOING

- Polishing the Diamond: You’ll be the owner of quality, identifying and fixing those "small" UX papercuts that make the difference between a tool and a craft.

- Building Complex UI Components: You won’t just be moving buttons. You’ll be diving deep into interesting technical challenges like building a custom Taxonomic filter, a sophisticated Date-Time picker, and expanding our new component library.

- Create a Design system. You hate technical debt and you get the chance to create components that other developers can use without needing a manual.

- Shipping with AI: You’ll use AI tools to augment your workflow, allowing you to step into the backend when needed or automate the
