This is a hands-on role in a lean 30-person startup combining deep tech, AI/ML, hardware, and IoT.

What you'll do

  • Design and optimize schematics, PCBs, and housings for solar-powered roadside units with cell connectivity and high-speed sensors
  • Write firmware and edge software (Python, C/C++) that bridges hardware constraints with system requirements
  • Conduct reliability hardening of power systems and connectivity to achieve 99.9% uptime in extreme weather conditions
  • Lead CAD iterations in Onshape to improve assembly yield, weatherproofing, and field serviceability
  • Collaborate with cross-functional teams on hardware-software integration and troubleshoot issues using oscilloscopes and logic analyzers
  • Support outdoor deployment and long-term maintenance of production devices across the Interstate Highway System

What they're looking for

  • Embedded systems design and firmware development
  • PCB schematic capture and layout (Altium)
  • Hardware CAD modeling (Onshape)
  • Python, TypeScript, and/or C/C++
  • Linux and IoT edge device development
  • Hardware debugging tools (oscilloscopes, logic analyzers)
  • Edge computer vision and sensor integration
  • AWS or cloud infrastructure basics

Benefits

  • Relocation support and signing bonus to Denver office
  • Personalized health coverage (ICHRA monthly allowance for individual/family plans)
  • 401(k) matching up to 4% with competitive equity package and annual tender opportunities
