ABOUT POSTHOG We equip every developer to build successful products https://posthog.com/handbook/why-does-posthog-exist. 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 a built-in data warehouse https://posthog.com/docs/data-warehouse, a customer data platform https://posthog.com/docs/cdp, and Max AI https://posthog.com/max, an AI-powered analyst that answers product questions, helps users find useful session recordings, and writes custom SQL queries. Next on the roadmap are messaging, customer analytics, ai task creation and coding based on customer data, logs and support analytics. Our values https://posthog.com/handbook/values are not a poster on the wall full of aspiration. They’ve come from how we really work, day in day out. PostHog is open source https://posthog.com/docs/self-host product led, and a default alive https://paulgraham.com/aord.html company that is well funded. 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 We are looking for an expert security generalist to assist with all things security at PostHog. Someone equally adept (and interested!) in building secure libraries, writing semgrep rules, hardening cloud deployments, improving network observability, and leading incident response. Someone to take the reins of our security operations, build out our detection pipelines, and ensure that when something goes bump in the night, we have the observability to know exactly what happened. We're a team that's building internal security products and agents - things like agents to automatically triage wiz alerts, automatically review pull requests, automatically assign vulnerability findings to the owning product team. In this role you’ll: - Build from Scratch: You aren't maintaining s
