Full-Stack Engineer

In this role, you’re not hacking together an AI agent hoping someone will use it — you’re building on top of a firehose of real customer data with immediate impact. You’re building agents on top of real customer data — not toy demos. PostHog already collects all the context agents need to be useful: analytics, sessions, events, feature flags, and more. Instead of copilots on the side, you’ll create background agents embedded into engineering workflows — changing how software gets built. Work with feedback from the largest open-source product engineering communities in the world. You will own 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. 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. All our products integrate with Max AI, so you'll likely be working with the Max AI team to implement AI features in your products. 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. 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. 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.
