Job Description

ABOUT POSTHOG

We equip every developer to build successful products https://posthog.com/handbook/why-does-posthog-exist.

We started with open-source product analytics, launched out of Y Combinator's W20 cohort https://posthog.com/handbook/story.

We've since shipped more than a dozen products https://posthog.com/products, including a built-in data warehouse https://posthog.com/docs/data-warehouse, a customer data platform https://posthog.com/docs/cdp, and PostHog AI http://posthog.com/ai, an AI-powered analyst that answers product questions, helps users find useful session recordings, and writes custom SQL queries.

Next on the roadmap are messaging, customer analytics, ai task creation and coding based on customer data, logs and support analytics.

Our values https://posthog.com/handbook/values are not a poster on the wall full of aspiration. They’ve come from how we really work, day in day out.

PostHog is Open Source, https://posthog.com/docs/self-host product led, and a default alive https://paulgraham.com/aord.html company that is well funded.

WHAT YOU'LL BE DOING

You'll be part of our Error Tracking team https://posthog.com/teams/error-tracking that built an error tracking product https://posthog.com/error-tracking that captures and ingests tens of millions of exceptions experienced by our customers users every day https://www.youtube.com/watch?v=IJJKLxhcsIA.
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’LL FIT RIGHT IN IF:

- 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.
