What you’ll do

You’ll join a technology community of product-focused and data-led product and platform engineers working at scale. We have a diverse ecosystem, spanning TypeScript on AWS, Go on GCP and Scala, we index on product-minded problem solving over language purity.

As a Senior Engineer you’ll own a slice of the product end-to-end, from design through to production, and you’ll build AI coding agents as your default. We’re looking for someone whose judgement is worth more than their typing speed.

From your first day you’ll have paid access to Claude Code, with a budget we don’t ration, and access to the systems you need through MCP. Our tools and conventions evolve quickly, and you’ll directly impact how we build from here.

• Own a slice of the product end to end:
• Work across the stack over time
• Build with AI coding agents as your default
• Stay close to the people who use what you build
