• Comfortable in working AI-first, with agentic tools as part of everyday craft.
• Strong collaborative skills and being able to comfortably drive ambiguous problems towards clarity and implementation.
• It would also be music to our ears if you have deep experience architecting scalable web applications in React and TypeScript, including server-side rendering, frontend architecture and performance work, along with familiarity with observability tooling and experimentation and product analytics platforms.
• Equal opportunity employer We believe that bringing people together from different backgrounds, experiences and perspectives makes for a healthy workplace, a more successful business and a better world. We value diversity and encourage everyone to come and soundtrack the world with us.
