Finance Manager

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 and iterating.

Woah - we're hiring the very first dedicated finance person at PostHog. This is a huge deal!

Working as part of the People & Ops team, you're going to take us to the next level at PostHog as we enter the world of growth financing and, one day, the public markets. You'll help us create the foundations of how our finance functions work, while also making sure the internal processes that need to run smoothly every month do.

We already have a bunch of processes and controls in place, so you won't be starting from scratch, but we know there are a lot of ways things could be running more effectively as we scale. Your role will be to balance growth and risk appropriately, implementing just the right level of process that is appropriate at each stage of the business.

• Owning our month-end closing process - running this like clockwork

• Preparing the company for our first accounts audit in 2026

• Making sure we're able to answer the BIG questions - how do we spend money? How do we create budgets? How do we account for usage-based revenue across 10+ different products?

• Preparing accounts for investors past, present, and future - you'll be an integral part of future funding rounds

What you won’t be doing

❌ Owning the financial model - though you'll definitely be deeply involved. This is a controls role more than an FP&A role.

• Worked in a SaaS business as a finance team member, leading on financial controls

• Worked with a business that has a usage-based billing model

• Been part of an accounts audit at a US topco

Nice to haves

• Qualified accountant is nice but definitely not necessary!

• Been part of a late-stage funded company that has scaled ($100M ARR+)
