Sr. Hardware System Integration Engineer, Off Board Charging Tesla Motors, Inc. 120000 - 252000 USD paid holidays, flex time, 401(k) United States, California, Palo Alto Sep 26, 2026

What to Expect The Off-Board Charging team is seeking a hardware integration engineer with 4+ years of industry experience specializing in EVSE hardware integration from prototype through production. This role will primarily focus on integrating, debugging, and validating power electronics and high- and low-voltage hardware-including custom PCBs, harnesses, grid-connected stages, and EVSE-vehicle communication interfaces-for next-generation charging products. You will serve as a technical anchor for EVSE hardware integration, driving cross-functional decision-making that bridges hardware, firmware, and controls. The role demands hands-on judgment to translate complex system interactions into clear integration and validation plans. You will define validation strategies, lead hardware bring-up, conduct system testing on the bench and in grid-connected environments, and support firmware integration (~30% of work) by reading and debugging C++ during system validation. You will partner with electrical, firmware, mechanical, test, manufacturing, and quality teams to bring designs from first bring-up through production ramp. What You'll Do

Integrate, test, and validate EVSE hardware and firmware across prototype, pilot, and production phases, with focus on power electronics, HV/LV subsystems, and EVSE-vehicle communications

Debug and triage integration issues on custom PCBs, harnesses, interconnects, and power stages; identify root cause and help implement and validate fixes with design and firmware owners

Develop and execute integration and validation test plans-including grid-connected, power quality, and signal-quality characterization using scopes, power analyzers, and DAQ-and align test milestones to program timelines

Lead cross-functional integration discussions with electrical, firmware, controls, mechanical, test, reliability, manufacturing, and supplier teams

Support early prototype development to de-risk new hardware, interconnect, and EVSE-vehicle communication designs before pilot and production builds

Read, comprehend, and debug C++ as needed to support system testing and firmware/controls integration during development cycles

Work with manufacturing and test teams to achieve production ramp with robust integration processes and high first-pass yield What You'll Bring

Strong foundation in hardware fundamentals with ability to bridge electrical schematics, harness design, and firmware behavior during integration and debug

4+ years hands-on hardware integration and validation experience in product development (EV, energy, automotive, or industrial)

Ability to read electrical schematics and use lab equipment (oscilloscopes, DMMs, power analyzers, electronic loads, DAQ) for bring-up and troubleshooting

Ability to read, comprehend, and debug C++ for system test and validation (firmware development not required)

Strong knowledge of one or more areas among power electronics, high-voltage systems, low-voltage embedded hardware, vehicle communication networks (e.g., CAN, Ethernet), custom PCB bring-up, and harness/interconnect debug; ability to integrate across these domains is paramount

Ability to design test scripts or automation (Python preferred) to improve bring-up and validation efficiency

High-voltage system integration or grid-connected testing experience, preferred

EVSE, charger, or grid code/compliance testing experience, preferred

Power electronics background (converter topologies, magnetics, protection), preferred

Bias toward systematic problem-solving, root-cause analysis, and explicit risk-based decision making; exceptional communication skills and ability to lead through influence
