Product Engineer

We’re equipping every developer to build successful products by giving them a suite of products to analyze, test, observe, and deploy new features. We currently offer product and web analytics, session replay, feature flags, experiments, a CDP, SQL access, a data warehouse, and LLM observability… and there’s plenty more to come.

PostHog was created as an open-source project during Y Combinator's W20 cohort. We had the most successful B2B software launch on HackerNews since 2012 with a product that was just 4 weeks old. Since then, more than 100,000 companies have installed the platform. We've had huge success with our paid upgrades, raised bags of money from some of the world's top investors, and have extremely strong product-led growth – 97% driven by word of mouth. 

We're growing quickly, but sustainably. We're also default alive, averaging 10% monthly revenue growth and with more than $20m ARR. We're staying focused on building an awesome product for end users, hiring a handful of exceptional team members, and seeing fantastic growth as a result.

What we value

• We are open source - building a huge community around a free-for-life product is key to PostHog's strategy.

• We aim to become the most transparent company, ever. In order to enable teams to make great decisions, we share as much information as we can. In our public handbook everyone can read about our roadmap, how we pay (or even let go of) people, what our strategy is, and who we have raised money from. We also have regular team-wide feedback sessions, where we share honest feedback with each other.

• Working autonomously and maximizing impact - we don’t tell anyone what to do. Everyone chooses what to work on next based on what is going to have the biggest impact on our customers.

Solve big problems -we haven't built our defining feature yet. We are all about acting fast, innovating, and iterating.

PostHog has grown primarily through word-of-mouth because developers actually like us (shocking, we know!). Now we want to meet developers where they already are - in the tools they use every day, probably whilst complaining about their failed deployments.

We're looking for a Product Engineer to build integrations with the platforms developers love using. You'll be creating native experiences that make adopting PostHog feel obvious, whether someone discovers us through the Vercel marketplace, sets us up via a GitHub Action, or configures us through their favourite deployment platform.

This job is ideal for someone who:

• Can work well with external teams and APIs. You'll be "hopping on a quick call" with engineers from platforms like Vercel, GitHub, and AWS. You'll need to navigate their APIs, understand their constraints and figure out the best way to integrate with them.

• Gets excited about developer experience. The best integrations feel like magic - they just work, and have docs that don't make you want to throw your laptop out the window.

• You've built a few integrations yourself, cursed at some OAuth flows, and waited with excitement for the 6th round of marketplace reviews to come through.

• You love finding the latest developer toy to play with, and figuring out which ones will stick around

• You will build integrations from scratch with developer platforms like Vercel, Netlify, AWS & GitHub

• You will design integration-specific onboarding flows that get developers set up with PostHog in minutes

• You will maintain and monitor existing integrations to make sure they are working correctly

• You will build tooling and infrastructure to make future integrations faster to create

• You will analyze our users to understand which integrations we should prioritise building

• You won't get detailed specifications for every integration (you'll need to research APIs and figure out the best approach yourself)

• You won't be selling PostHog to providers, doing business development or marketing - this is an engineering role, so no sales calls required (phew!)

• You won't be relying on another team to handle the listing and approval processes for integrations; you will handle the end-to-end process

• You won't be building one-off custom integrations for individual customers (no matter how much they love Salesforce)

Must haves:

• You'll have full-stack experience with relevant technologies (Python or similar, React or similar, extensive experience with APIs and third-party integrations)

• Experience building user-facing integrations with popular developer platforms and marketplaces

• You have started a project from scratch. You might have been a founder previously, or built an impressive side project in the dev tools space

• You have strong communication skills. We document everything, most of it publicly, and you'll be working with other engineers to get things shipped

• You move fast, have a strong bias for impact, and you don't shy away from stepping on toes

Nice to haves:

• You've worked in a high-growth SaaS company; ideally in the dev tools space

• Experience building marketplace apps for platforms like Vercel Marketplace, GitHub Marketplace, or Slack App Directory

• Partnership or developer relations experience - you've worked directly with platform teams at major tech companies

• Extensive experience with Django and TypeScript-based React

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!
