UI & SDK Web Engineer

About the Role

We are looking for a senior UI & SDK Web engineer to join our Web Observability team, responsible for both our dashboard UI (React + TypeScript) and our Web RUM SDK built on OpenTelemetry. This is a hybrid role that bridges product development and observability infrastructure—ideal for someone who’s as comfortable designing frontend components as they are contributing to open-source SDKs.

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)
