Backend Engineer

We're shipping every product that companies need from their first day, to the day they IPO, and beyond. The operating system for folks who build products.

We started with open-source product analytics, launched out of Y Combinator's W20 cohort. We've since shipped more than a dozen products, including:

• A built-in data warehouse, so users can query product and customer data together using custom SQL insights.

• A customer data platform, so they can send their data wherever they need with ease.

• PostHogAI, an AI-powered analyst that answers product questions, helps users find useful session recordings, and writes custom SQL queries.

Next on the roadmap are CRM, workflow, revenue analytics, and support products. When we say every product, we really mean it!

We are:

1. Product-led. More than 100,000 companies have installed PostHog, mostly driven by word-of-mouth. We have intensely strong product-market fit.

2. Well-funded. We've raised more than $100m from some of the world's top investors. We're set up for a long, ambitious journey.

3. Default alive. Revenue is growing 10% MoM on average, and we're very efficient. We raise money to push ambition and grow faster, not to keep the lights on.

We're focused on building an awesome product for end users, hiring exceptional teammates, shipping fast, and being as weird as possible.

You'll be part of our Error Tracking team that built an error tracking product that captures and ingests tens of millions of exceptions experienced by our customers users every day.
By using symbol sets we can unminify the captured exceptions and group them into issues with full code context that customers can then fix.
Error tracking has a massive impact on what we deliver and integrates with PostHog events, session replay, and revenue analytics, so you can see who an issue affected, what they were doing when it happened, and the impact on the business

You will be working with Rust to build a performant, scalable ingestion pipeline that handles millions of events per minute.
You'll investigate the minification and compilation details of various languages and with our mix of SDKs, you'll work with everything from source maps to debug symbols!

You'll operate like a product engineer, ensuring the pipeline can support spike detection, controlling the cardinality of threshold based alerts, and making improvements to our issue grouping algorithms, and you'll be adding observability and monitoring to make sure we always know what's happening under the hood

• You’re a builder. You bring strong skills in building resilient systems with a focus on developing in Rust. Python is welcome.

• Ingestion pipelines have not secrets for you. You have worked with Kafka, and ClickHouse or an other OLAP Database.

• You know your tools: You'll be working with Grafana and Terraform amongst others

• You love getting things done. Engineers at PostHog have an incredible amount of autonomy to decide what to work on, so you’ll need to be proactive and just git it done.

• You’re ready to do the best work of your career. We have incredible distribution, a big financial cushion and an amazing team. There’s probably no better place to see how far you can go.

If this sounds like you, we should talk.

We are committed to ensuring a fair and accessible interview process. If you need any accommodations or adjustments, please let us know.
