Backend Engineer — Ingestion

• Build and own the ingestion pipeline that processes tens of billions of events a month — and growing — across PostHog's platform. • Design elegant, efficient distributed systems that handle terabytes of data reliably without compromising data integrity. • Own the entire service end to end with no committees or overzealous PMs — the destiny of the ingestion pipeline is in your hands. • Work with a mixture of Node.JS and Rust for high-throughput processing, and data stores including Kafka, PostgreSQL, ClickHouse, S3, and Redis. • Ship small, confident, frequent changes in a natively remote, async-first engineering culture with two meeting-free days per week.

• Have experience working with highly scalable, event-driven distributed systems. • Have developed multi-tenant software-as-a-service products. • Have experience with Node.JS, Go, Rust, or similar languages. • Have worked with Kafka and PostgreSQL, Redis, or similar systems at scale. • Know how to ship changes quickly without breaking things.

• Have experience with customer data platforms or similar data analytics systems. • Have carried a pager and dealt with incidents in production. • Be comfortable provisioning and maintaining cloud infrastructure. • Have experience with benchmarking and profiling tools. • Have knowledge of observability systems and practices.

• Develop and maintain the infrastructure that captures, processes, and delivers billions of events a month across PostHog's platform. • Design distributed systems from first principles using the best tools for the job. • Build open-source software in the hot path — your code directly impacts customer and engineer experience. • Evaluate and re-evaluate technological choices as data volumes grow. • Collaborate asynchronously with a team spread across North America and Europe.

We have used PostHog's web analytics ourselves and genuinely loved the experience. The product is fast, thoughtfully designed, and surprisingly fun to use. PostHog is unlike most SaaS companies: their entire handbook is public, their codebase is open source, and they share revenue figures and board meeting notes with every team member. The company has raised $194M from investors, including Stripe, GV, and Y Combinator, reached a $1.4 billion valuation in 2025, and is targeting $100M in ARR by the end of 2026. They pay generously, benchmarking engineering salaries at the 90th percentile of San Francisco rates adjusted by location, with a fully public compensation calculator so you know your salary before you even apply. Employees on Glassdoor consistently highlight the flexible spending, genuine remote-first culture, and regular offsites, alongside a $1,500 quarterly budget for meeting up with colleagues anywhere in the world. Many team members are former founders, and the company is structured around small, autonomous teams that own their products end-to-end. If you are an engineer or builder who thrives on autonomy, ships fast, and wants to work on a product used by nearly 200,000 teams, PostHog is a rare opportunity.

• Work fully remotely from the UK or EMEA with GMT 0 to GMT +2 timezone alignment. • Receive significant equity in a well-funded, default-alive company. • Access unlimited paid holiday with a guaranteed minimum. • Enjoy two meeting-free days per week for focused building time. • Receive a home office budget and coworking credit. • Access private health, dental, and vision insurance. • Receive a training budget and pension contributions. • Attend company offsites and access PostHog's Hedge House. • Get paid $1,000 for the SuperDay paid work trial as part of the interview process.

PostHog is the operating system for software builders — shipping every product companies need from day one to IPO and beyond. With over 100,000 companies installed and revenue growing 10% MoM, PostHog is default alive and well-funded. The Ingestion team owns the pipeline that processes tens of billions of events a month across product analytics, feature flags, CDP, and more — with ambitions to add another zero to that number.
