Your work will directly empower millions of developers to build better, more reliable software, no matter which runtime powers their stack
- End-to-End Ownership: We believe in giving our engineers the autonomy to see their vision through. You'll have the freedom to plan, implement, and ship your code, from writing robust unit and integration tests to crafting crystal-clear documentation that educates both our team and our customers
- The AI-Powered Developer Experience: We're committed to leveraging the latest advancements to work smarter, not harder. You'll utilize AI tools to supercharge your productivity and focus on what truly matters: solving complex problems and delivering exceptional value

You'll have the chance to collaborate with influential organizations and committees such as TC39, the Node.js core team, and the OpenTelemetry SIG, representing Sentry and helping to steer the future of JavaScript standards and runtime interoperability
- Direct Impact and Connection: Say goodbye to layers of bureaucracy. You'll be on the front lines, assisting our Customer Operations team to squash critical bugs and interacting directly with our vibrant user base on GitHub and at industry conferences
You'll love this role if you
- Are a craftsperson who takes immense pride in building features that are not only functional but a delight to use
