Position Summary

The Electrical Systems Engineer will lead and support the development of high-voltage battery systems, power distribution architectures, and vehicle-level electrical integration. This role spans system design, requirements, embedded controls coordination, safety analysis, and hands-on prototype validation.

You will collaborate closely with mechanical, controls, software, and manufacturing teams to deliver robust systems through the full development cycle—from concept to system launch.

Key Responsibilities

Electrical & System Design

Design and document electrical architectures, schematics, wiring diagrams, and component selections for Li-ion battery systems, HV distribution, and vehicle integration.

Develop and maintain system requirements, interface definitions, DFMEAs, PFMEAs, DVP&R, and system test plans.

Apply strong engineering knowledge of HV components: contactors, switches, HVIL, insulation, isolation monitoring, safety interlocks, bus bars, sensors, and protective devices.

Support PCB/hardware development efforts (Altium preferred; OrCAD or equivalent considered).

Controls & Software Integration

Coordinate with controls and software teams on system behaviors, state machines, protection logic, and calibration.

Support embedded controls development using MATLAB/Simulink/Stateflow, model-based design, and C-based integration review.

Use CAN tools (Vector CANalyzer, CANape) to evaluate control systems, validate functionality, and troubleshoot issues.

Testing, Validation & Debug

Develop validation test procedures for system-level and component-level verification.

Perform hands-on prototype testing, fault evaluation, root-cause analysis, and troubleshooting of high- and low-voltage systems.

Follow lab and vehicle test procedures to evaluate system performance, safety interactions, and functional behavior.

Program & Cross-Functional Coordination

Work with internal team members and external suppliers to ensure successful design, build, and validation.

Participate in recurring technical review meetings to identify risks, integration issues, and quality concerns.

Assist in project planning—tracking timing, risks, status, and technical deliverables.

Documentation & Build Support

Generate and coordinate build documentation, assembly instructions, inspection sheets, and test records.

Support prototype build reviews, manufacturing handoff, and initial production readiness.

Qualifications

Education

Bachelor’s degree in Electrical Engineering, Controls, Computer Engineering, or Mechatronics from an accredited institution.

Equivalent experience will be considered.

Experience

5–15 years of experience in electrical or systems engineering for EV, hybrid, automotive, heavy vehicle, or defense systems.

Proficiency in electrical system architecture, safety concepts, and requirements flow-down.

Experience with:

MATLAB/Simulink/Stateflow

LabVIEW

Vector CANalyzer / CANape / CAN tools

SPICE / PSpice

Controls platforms (MotoHawk, dSPACE, ETAS preferred)

Hands-on experience with high-voltage battery systems, inverters, DC-DC converters, BMS, and vehicle electrical integration.

Familiarity with EV industry standards, ISO 26262 concepts, and relevant military or commercial vehicle standards (preferred).

Experience with PCB design tools (Altium) is a plus.

What You Bring

Strong analytical and problem-solving skills.

Ability to manage multiple technical tasks in a fast-paced, hands-on environment.

Excellent communication, collaboration, and documentation capabilities.

A proactive mindset with strong attention to detail.

Why Join This Opportunity

Work on cutting-edge battery systems, high-voltage electrification, and ruggedized energy products.

Be part of a small, agile engineering environment with meaningful technical ownership.

Exposure to diverse projects and close collaboration with customers and leadership.

Competitive compensation and opportunities for long-term growth.
