🦔 Read more about how we hire and how we think about diversity & inclusion.
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, Workflow, 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.
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 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 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 – 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 – 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.
You'll join the Twig team, which is building an AI-enabled product development loop to achieve "product autonomy". Our vision is to replace the current human-driven cycle with an AI-first workflow.
We're creating a desktop app alternative to IDEs, designed as an agentic development environment. This means orchestrating multiple AI agents (not just stateless coding assistants) and enriching them with PostHog product data.
You'll scale the language model gateway to handle 10K–100K requests/second, ensuring low latency and high reliability.
You'll build and optimize coding sandboxes for AI agents, enabling safe, isolated execution of generated code.
You'll contribute to the AI-first product development loop, from analysis to auto-merge, with a focus on robustness and scalability.
You're a backend-focused builder. You have professional experience with Python and TypeScript, and you're open to other languages (no tech stack zealotry here)
You thrive in scale-up environments. You've experienced the journey from unicorn to decacorn growth and understand the real challenges of scaling (not just Big Tech abstractions)
You love solving hard problems. Whether it's optimizing gateway performance or designing sandboxing systems, you're driven by impact
You believe in engineering-led decision-making. You want to work where engineering and product teams function as one unified unit
You're excited about AI-enabled autonomy. You'll help build the infrastructure that powers AI analysis, coding, and review, and ultimately, auto-merged features
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!
