• 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
