О компании и продукте

• Product development used to mean manually writing code, running analysis, diagnosing bugs, and rolling out changes using dozens of tools.
• PostHog is the only platform that acts like a co-pilot for you (and your AI agents) to do it all – autonomously.
• 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:
• PostHog Code https://posthog.com/code, the only AI devtool that understands your product, not just your codebase.

Задачи

• Our team is spread across North America and Europe and we're looking for another engineer in Europe or the UK
• We're growing very quickly at PostHog, so quickly that the numbers in our job descriptions often get out of date
• Our ingestion pipeline is currently processing 10s of billions of events a month and we're hoping to add one more zero to that soon
• You’ll be responsible for developing the infrastructure to capture all that data, process it reliably, and provide it to other parts of PostHog's platform, such as product analytics, feature flags, CDP, and more

Требования

• We're seeking a Europe/UK based ingestion pipeline engineer who
• Thrives on challenges of building systems that process billions of events per day
• Gets excited about designing elegant and efficient systems that can handle terabytes of data without giving people insomnia
• Understands the importance of data integrity and reliability for customers
• The ideal candidate has experience with high-throughput data processing systems such as
• Analytics platforms
• Metric collection systems
• Log aggregation engines
• Streaming and batch-processing pipelines
• We use a mixture of Node.JS and Rust for high-throughput processing
• We store most of our data in Kafka, PostgreSQL, Clickhouse, S3, and Redis, but with the growing volume of data, we're constantly re-evaluating our technological choices
• We're looking for someone who understands the principles of designing distributed systems and can use them to pick the best tools for the job
• WHAT MAKES THIS ROLE UNIQUE
• At PostHog you won't get stuck maintaining an obscure microservice or working in the shadows of the product org, instead, you will
• Own the entire service from end-to-end: No committees or overzealous PMs, the destiny of the ingestion pipeline will be in your hands
• Build open-source software: You'll be able to show your Rust-fu to your friends and family (and security researchers too)
• Build in the hot path: Your code will decide whether our customers and engineers have a good time or not
• Start from first principles: No cookie-cutter solutions here, you'll be safe from AI agents for a good while
• See immediate results: Small, confident, frequent steps forward – that's how we like to move
• Experience working with highly scalable, event-driven distributed systems
• You have developed multi-tenant software-as-a-service products
• Experience with Node.JS, Go, Rust, or similar languages
• You have worked with Kafka and PostgreSQL, Redis, or similar systems at scale
• You know how to ship changes quickly without breaking things

Будет плюсом

• Experience with customer data platforms or similar data analytics systems
• You've carried a pager and have dealt with incidents
• You're comfortable with provisioning and maintaining cloud infrastructure
• Experience with benchmarking and profiling tools
• Knowledge of observability systems and practices
• We are committed to ensuring a fair and accessible interview process. If you need any accommodations or adjustments, please let us know
