About the Job

Requirements

  • At least 4 years of electrical engineering experience on robotic, vehicle, or electromechanical systems.
  • End-to-end printed circuit board design experience on hardware that the candidate subsequently brought up and debugged under load.
  • Depth in power electronics across battery packs and battery management systems, direct-current-to-direct-current conversion, power distribution, and charging.
  • A track record of shipping hardware with vendors and contract manufacturers.
  • High ownership, bias for speed, and comfort with ambiguity.

Responsibilities

  • Own the electrical architecture of TAR’s deployment machines, including high- and low-voltage distribution, battery and charging systems, and the power budget for robots that work a full shift off-grid.
  • Design boards end-to-end for motor control, sensing, power, and compute, including schematic capture, layout, bring-up, and validation.
  • Specify and integrate motor drives and actuation electronics, working with mechanical and controls engineers on current sensing, loop tuning, and protection.
  • Integrate the sensors and compute that enable core autonomy functions, including navigation, perception, controls, and communications.
  • Design harnesses, connectors, and enclosures that survive dust, heat, vibration, and rough handling on an active jobsite.
  • Own electromagnetic interference/electromagnetic compatibility, grounding, thermal management, and electrical safety, including emergency stops, interlocks, overcurrent protection, and fault handling on machines that move heavy loads around people.
  • Bring up new hardware on the bench and in the field, and debug it under real load.
  • Own the build package and manufacturer handoff, including sourceable bills of materials, testable boards, and harnesses built for repeatable production.

Desired Qualifications

  • Experience with high-voltage battery systems and traction-class power electronics.
  • Experience with functional safety for mobile machinery, including ISO 13849, ISO 25119, or similar standards.
  • Experience with ruggedization and ingress protection for outdoor or off-highway equipment.
  • Firmware fluency with embedded C/C++, real-time operating systems, and controller area network.
  • Experience with off-highway, construction, or agricultural vehicle electrical systems.

About the Company

TAR

Off-grid power plants for AI data centers

TAR builds and operates behind-the-meter power plants for AI data centers that cannot wait out a utility interconnection queue. The company designs islanded microgrids pairing solar, battery storage, and gas peakers, then manufactures, installs, and runs them, handling power electronics, microgrid controls, dispatch software, and site construction in-house. Compared with grid interconnection, which can take years to clear, an off-grid plant can be sited and energized on the developer's own schedule, and TAR says it is working with a large compute provider and targets 5 GW by 2028. Its goal is to remove power as the constraint on AI buildout by owning generation end to end.
