Mechatronics Engineer — Robotics & Real-Time Control

TAR; San Francisco (CA); On-site; USD 120,000 - 190,000; Full time

Job summary

TAR is developing the world’s first off-grid power plant for data centers, combining hardware and software to power GW-scale AI infrastructure. The Mechatronics engineer will own electrical integration, firmware, and drive the machine’s control systems at our San Francisco robotics facility, with field time at the GW-scale campus in West Texas.

You will collaborate with mechanical and electrical teams, select motors and sensors, implement robust safety circuits, and push performance in extreme

Qualifications

• 4+ years of electrical engineering experience in robotics or mobile/field robotic systems.
• Deep fluency in power electronics, motor control, and sensor integration in noisy environments.
• Hands-on embedded skills: firmware in C/C++ for real-time control, CAN/EtherCAT, debugging with a scope.
• Track record of taking an electromechanical system from schematic to working hardware.

Responsibilities

• Own the driver’s electrical integration and fleet architecture from the electrical team: battery, power distribution, motor controllers, safety circuits, connectors and harnessing resistant to dust, heat and vibration.
• Select and integrate motors, drives and actuators with the mechanical team, and tune motor control for locomotion and the pile-driving tool head.
• Design and build the sensing stack: encoders, IMU, load/force sensing, RTK-GNSS, and limit/proximity sensing.
• Develop embedded firmware and real-time control, including CAN bus architecture, control loops, interlocks, fault handling, telemetry and logging.
• Stand up the electrical test and bring-up process: bench testing, hardware-in-the-loop, field debugging and root-cause analysis.
• Design for the environment: EMI, thermal management in hot conditions, ingress protection, field serviceability.
• Support transition from prototype to small fleet through wire harness DFM, documentation and supplier management.
