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.

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.

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 contractors, 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.

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…
