Sr. Electrical Systems Engineer – EV / High Voltage Systems

Location: Troy, Michigan, USA

Company: Hybrid Design Services, Inc. (www.hds.us)

Job Type: Full-time – Onsite

About Us

Hybrid Design Services, Inc. (HDS) is an engineering and manufacturing company specializing in advanced battery systems, high-voltage power distribution, ruggedized energy systems, and custom electrification solutions. We support OEM, commercial vehicle, specialty, and defense customers with rapid prototyping and production-intent system development. We are seeking a highly capable Electrical Systems Engineer to support the design, development, integration, and validation of complex high- and low-voltage vehicle systems.

Position Summary

The Electrical Systems Engineer will lead and support development of high-voltage battery and distribution systems, power distribution architectures, and vehicle-level electrical integration. This role spans system design, requirements development, 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 / Areas of Impact

Electrical & System Design:

• Design and document electrical architectures, schematics, wiring diagrams, and component selections for lithium-ion (Li-ion) and other battery chemistries, high-voltage (HV) distribution, and vehicle integration.
• Develop and maintain system engineering artifacts, including requirements, interface definitions, DFMEAs/PFMEAs, and DVP&R/test plans.
• Apply strong engineering knowledge of high-voltage components, including contactors, switches, HVIL, insulation/isolation monitoring, safety interlocks, bus bars, sensors, battery cells/packs, and protection devices.
• Support hardware development and design reviews, including PCB schematic reviews (Altium preferred; OrCAD or equivalent acceptable).

Controls & Software Integration:

• Collaborate with controls and software teams to define system behavior, state machines, protection logic, and calibration strategies.
• Support embedded controls development using model-based design tools (MATLAB / Simulink / Stateflow) and assist with C-based integration reviews.
• Utilize CAN tools (e.g., Vector CANalyzer, CANape) to evaluate system performance, validate functionality, and troubleshoot issues.

Testing, Validation & Debug:

• Develop and execute validation test procedures for both component- and system-level verification.
• Perform hands-on prototype testing, including fault evaluation, root-cause analysis, and troubleshooting.
• Follow lab and vehicle test procedures to assess system performance, safety interactions, and functional behavior.
• Utilize tools such as SPICE/PSpice, LabVIEW, CAN tools, and battery test equipment for analysis and validation.

Program & Cross-Functional Coordination:

• Lead and support system engineering activities across the development lifecycle, including requirements management, integration, and validation.
• Collaborate with internal teams and external suppliers to ensure successful design, build, and validation outcomes.
• Participate in technical reviews to identify risks, integration challenges, and quality concerns.
• Assist in project planning by tracking timing, risks, status, and technical deliverables.

Documentation & Build Support:

• Develop and coordinate build, assembly, inspection, and test documentation.
• Support prototype builds and ensure alignment between design intent and physical implementation.
• Contribute to continuous improvement of engineering processes, documentation quality, and test methods.

Qualifications

Education:

• Bachelor’s degree in Electrical Engineering, Controls Engineering, Computer Engineering, Mechatronic Engineering, or a related field from an accredited institution (required).
• Master’s degree in a relevant field, or equivalent advanced experience, preferred.
• Equivalent combinations of education and applicable engineering experience may be considered.

Experience:

• 8–15 years of experience in electrical and/or systems engineering within EV, hybrid, automotive, heavy vehicle, or related defense applications.
• Strong proficiency in electrical system architecture, system engineering methodologies, requirements definition/flow-down, and safety concepts.
• Strong proficiency in applicable simulation and analysis tools: MATLAB/ Simulink/ Stateflow, LabVIEW, CAN tools (e.g., Vector CANalyzer, CANape), SPICE/PSpice, etc.
• Controls platforms (e.g., MotoHawk, dSPACE, ETAS) preferred.
• Hands-on experience with design and development of high-voltage systems, including battery packs, BMS, inverters, DC-DC converters, and vehicle electrical integration.
• Experience with battery pack and power electronics assembly, validation, EOL testing, and service is strongly preferred.
• Familiarity with EV industry standards, functional safety (ISO 26262 concepts), and relevant commercial or military standards preferred.
• Experience with PCB design tools (Altium or equivalent) is a plus.
• ISO 26262 or comparable functional safety certification is a plus.

NOTE: Eligibility to work on U.S. defense-related programs is required; U.S. person status may be necessary in accordance with applicable export control regulations.
