You’ll work on internal tools, developer-facing dashboards, and high-performance instrumentation libraries—all aimed at helping the world’s best engineering teams understand and improve web performance. You’ll also have the opportunity to collaborate with the OpenTelemetry community and influence the future of web observability standards. What You’ll Do - Contribute to both the dashboard UI and Embrace Web SDKs used by our customers and internal teams - Build performance monitoring and diagnostics tools for modern web applications - Help shape our SDK design and upstream contributions to OpenTelemetry - Collaborate with Product, Design, and Engineering teams to deliver user-friendly, data-rich experiences - Partner with Customer Success to incorporate feedback from developers using our SDKs and dashboards - Establish best practices for code quality, modularity, testing, and observability Basic Qualifications - Deep proficiency in TypeScript, including advanced type system features - Strong experience with React and modern frontend architectures - Familiarity with browser internals (e.g., performance APIs, Web Vitals, event loop behavior) - Experience building or maintaining client-side SDKs or instrumentation tools - Strong advocate for testing, with experience using tools like Jest and Playwright/Cypress - Comfort debugging and optimizing both applications and libraries - Excellent verbal and written communication skills - Experience using Git and modern CI/CD workflows Preferred Qualifications - Experience with OpenTelemetry or other observability frameworks - Contributions to open-source projects in the JavaScript/TypeScript ecosystem - Familiarity with browser privacy, data collection consent, and sampling strategies - Experience designing developer APIs or libraries for long-term stability - Experience with data visualization libraries like Recharts and D3 - Interest in performance profiling, memory leak detection, and low-level browser behavior - A love of Star Wars (or maybe Star Trek) Work Culture & Travel We are a remote-first company. This role is open to candidates located anywhere in the U.S. or Canada. We believe in regular in-person connection and expect travel for team offsites and collaboration to be approximately once per quarter. The cash compensation for this role is in the $135k-165k range. In addition to base comp for this role, we offer equity in the form of options, a variety of benefits, and the opportunity to grow in an exciting and collaborative environment. Actual compensation may vary based on level, experience, and skillset as assessed in the interview process.

You will develop and maintain dashboard UIs and Web SDKs while contributing to open-source observability standards. You will also collaborate with cross-functional teams to build performance monitoring tools and incorporate developer feedback.

Candidates must have deep proficiency in TypeScript and React, along with experience building client-side SDKs or instrumentation tools. Strong knowledge of browser internals and a commitment to testing best practices are essential.
