  • • Maintain and enhance observability tooling to provide real-time insights into system performance and reliability.

  • • Engage in team offsites and in-person collaboration opportunities in locations including New York, San Francisco, Barcelona, Toronto, Italy, and France.
  • • Contribute to a high-growth AI-native ERP environment where financial stack scalability matches the velocity of fast-moving customers like Mercor and Function Health.
  • • Deliver systems that support zero-day financial closes and power the financial core of the world’s fastest-growing companies.
  • • Translate customer-centric mission into technical execution, prioritizing work that delivers maximum impact even when outside original scope.

🎯 Requirements

  • • 5+ years of software engineering experience with a track record of leading large-scale projects and architecting scalable systems
  • • Deep expertise in cloud infrastructure, distributed systems, or developer productivity
