We're working with a fast-growing, venture-backed SaaS company that's reshaping how engineering teams monitor and optimize frontend and mobile performance.

Contribute to the OpenTelemetry ecosystem
Design and optimize systems to handle millions of sessions per day

What We're Looking For

Strong experience with JavaScript and modern frontend performance techniques
Deep understanding of web vitals, tracing, and browser debugging tools
Experience building or maintaining SDKs/libraries used by developers
Open-source contributions or community engagement is a plus
6+ years of professional software engineering experience
BS in Computer Science or equivalent hands-on experience

Perks & Benefits

$150K-$250K base salary (depending on experience)
100% remote work (U.S. only)
Comprehensive health, dental, and vision coverage
Flexible PTO and working hours
Collaborative, fast-paced engineering environment
Work with modern tools and real-world performance problems
