Job description

Lead Software Engineer

Sedaro is hiring a Lead Software Engineer to optimize the performance of our data visualization platform for aerospace simulation.

What You'll Do

  • Design and build high-performance productivity tools with impactful incremental releases
  • Profile and eliminate bottlenecks across our Cesium-based visualization pipeline and data processing backend
  • Optimize API response times and data throughput for scaling complexity
  • Build performance testing and observability that catches regressions and guides decisions
  • Become an expert on rendering performance, shaping how the team approaches speed and efficiency as we scale

Benefits

  • Unlimited PTO
  • 401(k) with 4% match
  • 100% premium payment for medical insurance
  • Parental Leave
  • Flexible work schedule with core hours
  • Company provided lunches 3 days a week
