The company is trusted by major enterprises and thousands of developers worldwide, with tens of millions of monthly SDK downloads.
Product engineers here own the full lifecycle of a feature: from talking to users and writing the spec, through shipping the code, to writing the docs and the public changelog post.
No handoffs — you see features through from user problem to production.
Recent examples of features owned by a single engineer include a major agents release, a TypeScript SDK rewrite on OpenTelemetry, and a hosted MCP server for prompt management.
That's the scope and ambition of this role.
What You'll DoOwn features end-to-end — user calls, spec writing, implementation, documentation, and public-facing changelog posts.
No handoffs, full accountability.
Work the full stack — React frontend, Next.
js backend, ClickHouse analytics, and Python/TypeScript SDKs.
You touch whatever the feature demands.
Build in the open — write code that ships to the open-source community, respond to GitHub issues, review public PRs, and contribute to developer-facing documentation.
Talk to users — participate in user interviews and translate feedback into product decisions and engineering solutions.
Contribute to platform observability — work on tracing, monitoring, evaluation pipelines, prompt management, and cost/latency analytics.
