Senior Software Engineer, Telemetry ExperienceNew€81K–€220K

The opportunity

Sentry's SDKs instrument dozens of platforms and our ingest pipeline takes in billions of events every day. The Telemetry Experience team owns what happens next: the product surfaces and APIs where that telemetry turns into something a developer can actually debug with.

What you'll do

  • Own projects end to end. Take a problem from a rough customer complaint: through scoping, design, implementation across the stack, rollout, and measurement. You'll write the design doc, cut the work into shippable pieces, and stay with it until the numbers move

  • Work across the full stack of the Sentry monolith. React and TypeScript in: the browser, Django and Postgres behind the API. Most projects here touch both, and the interesting decisions live at the seam

  • Partner closely with SDK and ingest teams. Telemetry arrives exactly as the: SDKs send it and as the pipeline shapes it. You'll shape those contracts together with the engineers who own them, rather than working around what shows up

  • Collaborate daily with product managers, designers, and other product: engineers. You'll bring the technical perspective that makes a design better, explain constraints in terms of what they cost the user, and sweat the details other people skip: empty states, error messages, loading behavior, the edge case that only bites 2% of accounts

  • You'd rather own an outcome than a ticket. You take ambiguous problems,: decide what to build, drive it across team boundaries, and follow through after launch. Nobody has to hand you a spec

  • You're obsessed with making an experience smooth. Friction offends you. You: notice the extra click, the confusing label, the query that takes 400ms too long - and you fix them instead of filing them

What they're looking for

  • + years of professional experience building and shipping full-stack web applications
  • Strong experience with React and TypeScript, and with Python (Django or: similar) backed by a relational database such as PostgreSQL - depth in one side and real competence in the other is fine
  • A track record of driving non-trivial projects end to end, including the: parts that require getting other teams to agree with you
  • Excellent written and spoken English communication skills
  • Experience leveraging AI-powered development tools to enhance productivity and code quality
