About the Role

Reflex Robotics is seeking a Senior Electrical Engineer to own the robot's power electronics and power distribution architecture. This role involves defining requirements, making system-level architecture decisions, and guiding designs from concept through testing and deployment, while collaborating with junior engineers and external resources.

Responsibilities

  • Define requirements for power electronics and power distribution architecture.
  • Make system-level architecture decisions for power systems.
  • Take designs from concept through bring-up, testing, and deployment.
  • Work closely with junior engineers and external layout resources to execute designs.
  • Miniaturize motor drives by reducing bus capacitance and switching-stage size without sacrificing efficiency or creating EMI problems.
  • Design the power system safety architecture, including safe startup, shutdown, fault handling, and battery hot-swapping.
  • Design and validate a custom battery management system.
  • Improve motor inverter performance, reliability, thermal performance, and packaging.
  • Diagnose and mitigate conducted and radiated EMI across the robot.

Requirements

  • Strong electrical engineering fundamentals.
  • Deep experience designing power electronics systems, ideally in the ~48V range.
  • Experience with motor inverters, motor drives, or similar high-current switching systems.
  • Strong PCB design, board bring-up, test, and debug skills.
  • Comfortable debugging power electronics with scopes, power supplies, current probes, and other lab equipment.
  • Strong understanding of system-level tradeoffs across electrical, firmware, mechanical, thermal, and cost constraints.
  • Ability to independently define technical requirements and make architecture and design decisions.
  • Experience taking complex electrical designs from concept through prototype and validation.
  • Strong communication skills and ability to lead technical work across multiple contributors.
  • BS or higher in Electrical Engineering or a related field.
