About the role

Senior Mechatronics Engineer to bridge mechanical, electrical, and robotics teams working on high-acceleration turret slewing and real-time motor control for a counter-drone system. Onsite in Austin, TX; direct hire, full-time; US citizenship/visa required.

Responsibilities

  • Cross-Functional Interface: Serve as the primary technical bridge between mechanical design and electrical engineering.
  • Motor & Actuator Selection: Define motor specifications based on required slew rates and turret mass, performing the necessary calculations for torque and RPM.
  • Motion Control & Tuning: Implement and tune high-bandwidth control loops (PID) to ensure stability during aggressive, high-speed tracking maneuvers.
  • System Debugging: Lead the triage of failures at the hardware-software boundary, identifying if an issue is mechanical, electrical, or software-based.
  • Robotics Integration: Translate tracking outputs into reliable motor commands, ensuring the 'body' of the turret reacts with zero margin for error.

Qualifications

  • Experience: Demonstrated success in mechatronics, specifically with high-performance motion control and motor drivers.
  • Programming: Proficiency in C, C++, or Rust for speed and direct hardware interaction.
  • Analytical Skills: Strong ability to model and calculate mechanical loads and translate them into electrical requirements.
  • Hands-on Rigor: Skilled in managing scopes, logic/CAN analyzers, and basic rework.
  • Compliance: U.S. Citizenship and the ability to pass a background check
