Robotics Electrical Engineer — End-to-End Hardware

TAR; San Francisco (CA); Hybrid; USD 140,000 - 165,000; Full time

Job summary

TAR is seeking an Electrical Engineer in robotics at our San Francisco facility. You will own electronics end-to-end from schematic capture through layout, bring-up, and validation, with regular field time at our West Texas campus.

This mid-to-senior individual contributor role requires deep power electronics experience, including battery packs, BMS, and high-reliability hardware for off-grid operation. Based in San Francisco, you’ll collaborate with a multidisciplinary team under ambitious

Qualifications

• 4+ years of electrical engineering experience on robotic, vehicle, or electromechanical systems.
• End-to-end PCB design experience with live-load bring-up and debugging.
• Power electronics depth across battery packs and BMS, DC-DC conversion, power distribution, and charging.
• Track record 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: 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: navigation, perception, controls, and comms.
• Design harnesses, connectors, and enclosures that survive dust, heat, vibration, and rough handling on an active jobsite.
• Own EMI/EMC, grounding, thermal, and electrical safety, including E-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: sourceable BOMs, testable boards, and harnesses built for repeatable production.
