Join a startup within a startup Starting a job at a company of 230 + people can be intimidating! With our small teams structure, it's like working at a startup within a startup. This allows each team to operate as autonomously as possible. Many of our team members are former founders. Here they can focus on building great products without the distraction of running payroll, fundraising, etc - while still enjoying huge upside potential.

This message brought to you by our co-founder James Hawkins @james406 yo, i’m james, one of the two co-founders, and there are a lot of things i can’t offer you… we don’t offer career progression frameworks we don’t offer mentorship we don’t offer lots of meetings we don’t hold back if we think something is wrong i don’t offer many capital letters Reply Repost Like James Hawkins @james406 if you join, my job is to provide an environment where we coach you to build the best products you can. Reply Repost Like James Hawkins @james406 it looks like: high expectations - i expect you to decide what to ship, for you to ship fast and for you to then iterate with users. you don’t have to do this alone, there are lots of friendly, deeply skilled and helpful people here - you just need to make sure you go get help instead of assuming it will come to you coaching for your team in the early days of a new product growth reviews of your product when it is popular to scale it or split it into more products lots of deep work time we will raise feedback constructively and will encourage crazy ideas lots of weird inside jokes Reply Repost Like James Hawkins @james406 i believe you focusing on shipping products and learning from this is how you progress your career. anything else is a means to this end. Reply Repost Like James Hawkins @james406 if you are joining a role outside of engineering, the concepts are exactly the same. that’s why we’re well known for a very different approach to marketing, sales, ops, recruitment and design. Reply Repost Like James Hawkins @james406 come work with people that are truly great at, and focused on, what they do. Reply Repost Like A really long quote (It was so good we just couldn't cut it down.) Dylan Martin Product Engineer Self-Driving Team Joined in May 2024 At PostHog I'm given the trust to work on things that I think matter for the business and our customers. There are no politics, no micromanaging, and pretty extreme amounts of autonomy for every employee. I've never worked at a company that can ship so well and so fast. The people here are of incredible caliber, and management just gets out of the way (while also being helpful) so everyone can just can do their job in the best way possible. Basically everything you hate about your job is the exact opposite here at PostHog. It's the weirdest, coolest place I've ever worked. Get to know us in our company handbook Almost any question you'll have about working here is answered in our public handbook. But here are some highlights you might be interested to know: Our revenue is over $50 million a year We're default alive If you join us, you will be expected to take a stance on if pineapple belongs on pizza Visit the handbook Handbook chapters Why does PostHog exist? 1 How we got here 2 How we get users 3 Who we are building for 4 How we make users happy 5 How we make money 6 Enduringly low prices 7 Deciding which products to build 8 A wide company with small teams 9 How we're building a world-class team 10 What we value 11 Providing a world-class engineering environment 12 Not running out of money 13 Where are we going? 14 How you can help 15 Who we look for Our IEP (ideal employee profile) TL;DR: We don't hire middle management. Fun fact: We have an internal Slack channel called #do-more-weird where we discuss crazy ideas that most companies save for April Fool's Day. Weirdos We look for adventurers. We're here to take a small company to IPO, and beyond. We will only get there if we think differently to everyone else. We're not a fit if you want a predictable career. Joe Martin Joe Martin worked as a clown, a morgue cleaner, and a chainsaw salesman before joining the Marketing Team Marketing Team , which he now leads. Individual contributors We think it's more important to hire exceptional people, then give them autonomy and plenty of context. We're not a fit if management responsibility is what motivates you. Thomas Obermüller Thomas Obermüller was CTO for his previous company of 120 people before joining PostHog as a software engineer on the Product Analytics Team Product Analytics Team , which he – surprise! – leads. Low egos Fast, scrappy people thrive here. We're informal, we use clear language and get a broad variety of work done fast. We're not a fit if you want process. Cameron DeLeone Cameron DeLeone worked for an $11 billion startup, then was Vice President of a poultry farm before joining PostHog as a CSM. Unexpected benefits Perks you'll only find here Two meeting-free days per week After extensive research, we've found the best way to ship fast is to have fewer meetings. *Illustration is not indicative of a product engineer’s calendar at PostHog. We actually have relatively few meetings. Company off-sites in exotic locations Each year we organize fully paid company off-sites. The highlight is the hackathon where we team up to build things that aren't on our roadmap. Off-site history: Year Location 2020 Tuscany 2021 Portugal 2022 Iceland 2023 Aruba 2024 Mykonos 2025 Tulum 2026 Barbados 2027 Hackathoning poolside in Mykonos Dope Roasting Co. in Athens, Greece – was a great place to build pages like this (RIP) Co-working or café credits on us If heading out to a co-working space or getting some overpriced coffee from boogie coffee shops is how you do your best work, you get to charge it to your company card – everyone gets one. Small team off-sites You'll meet up with your small team somewhere fun periodically. Sometimes multiple small teams get together. We have a special budget for you to do this. Recent small team off-sites have been in Sicily, Lisbon, Santiago, Cartagena, Sedona (Arizona), and Palm Springs (California). The Website & Docs + Marketing teams floating down Lake Austin Where the walls are definitely not YC Pantone orange... Access to the Hedge Houses We have a dedicated [coworking space](https://posthog.com/handbook/people/hogpatch) in San Francisco (SF) where you'll often find YC founders/members and some of our team working together. In London, we have a house where you can both work and relax, giving you options for collaborative or solo work in the city. There's also a house in Cambridge, UK available for employees to work from or stay at. The boring benefits Everybody offers healthcare, paid time off, and a laptop, so we organized our benefits by awesomeness. (Would we even be a tech startup without these?) The one exception is equity (which you get), but is so unique that it deserves its own section below. Unlimited paid time off (25 days minimum!) You're required to take at least 25 days off per year. (If you don't, you will be locked out of Slack. Just kidding.) This doesn't come out of your sick leave or generous parental leave. Training budget Pick up new skills on the job with an annual training budget, plus free books and an Audible subscription. 401k matching or pension plan Up to 4% matching for U.S. employees Carbon offsetting We contribute to Project Wren when we travel for work. Home office Get whatever you need to have an ergonomic setup at home so you can do the best work of your life. Private health, dental, and vision insurance US, Canada, & UK only The most transparent company, ever We're open-source and fully remote. In order to enable teams to make great decisions, we share as much information as we can. This includes: Board meetings We share slides from each board meeting internally. When everyone knows the direction we're headed and the obstacles we face, they can decide where their time is best spent. Fundraising & finances We keep our team informed about fundraising during the process and share a monthly report covering revenue, runway, and more. It's nice when you can see your hard work paying off (literally). Constructive feedback Transparency is a two-way street. We encourage individual feedback and run regular 360-degree group sessions during small team off-sites, so everyone can improve. Latest monthly financial report Management report August 2026 1 of 8 Confidential Open report Live, Laugh, LEquip every developer to build successful products Our jobs are zero fun. Here are some things that have made it a little less insufferable. IsGoogleAnalyticsIllegal.com We spun up a microsite when courts across the EU started to find Google Analytics in violation of GDPR. That one time we found favor on Hacker News We appear on Hacker News quite often. And we don't even submit all of our own posts! Taught people how to actually use post-its A company will not find success unless they are in the top 1 percentile of using post-its. You can learn how to do that too . Patrick Collison tweeted about us When the co-founder of Stripe tweets about you unsolicitedly, it's a big deal. 6+ hour GitHub star live stream When we hit 10,000 stars on GitHub, live streamed to thank every single one of them . 35k+ GitHub stars We are honored to be the most popular open source Product OS on GitHub. (Yes, we defined the category, but still...) Won't you be our next star? Enterprise mode TM on PostHog.com Same website, just with bigger words. It makes us more approachable to the suits. Find it under the Account menu (top right) on the homepage. Built big things with small teams Our Data warehouse was built by a team of two. Same with Session replay . And we shipped a Google Analytics replacement with a team of one. Wrote the ClickHouse manual that other companies use We literally wrote a ClickHouse manual that other companies use. Crazy popular with the YC crowd One of the most adopted products by new YC startups PostHog for enterprise We built a page for selling to large enterprises. It is very serious. Hedgehog mode It's like a Chia pet, but for hedgehogs. Find it inside PostHog by searching with CMD + K . DPA generator, featuring a Taylor Swift edition It's the most fun you've ever had filling out a legal document. Human-readable privacy policy A privacy policy that won't put you to sleep. Be sure to check out the Tweet-style summary, too! Nice things we didn't coerce anyone into saying Working at PostHog is a truly unique experience, which has probably set me up to hate any other job out there. I get to work on bizarre and challenging projects and no day is ever the same. Lottie Coxon Graphics Lead I hate how much I enjoy working at PostHog. It has ruined all other companies for me. Thanks a lot. Charles Cook Generic Exec Person I wake up so excited to get to work that sometimes I pinch myself to make sure I'm not dreaming. The combination of high expectations, high trust, high autonomy, and high reward is so unique and drives me to improve every day. Paul D'Ambra Engineer exec for anecdotes PostHog enables me to do my best work. I am autonomous, empowered to do what I think is best, and truly on the maker schedule. Ian Vanagas Technical Content Marketer We take autonomy seriously. It's not the perfect fit for everyone, but for someone like me who has strong opinions and likes to make her own decisions, PostHog is an incredible place to be. Raquel Smith Engineering exec person
