Electrical Systems Engineer

Key Responsibilities

• Design, analyze, test, and integrate bespoke mission equipment kits into an array of International® vehicle electrical architectures, with a primary focus on power, ground, signal, and network interfaces.
• Configure and integrate vehicle network communication (CAN, LIN, Ethernet) to pass required signals between the vehicle and the integrated kits.
• Layout and configure wiring harnesses, including wiring schematics — properly sizing and selecting conductors, connectors, and terminals for kit integration.
• Perform electrical load analysis, power distribution design, and circuit protection sizing for added equipment.
• Define, develop, and document vehicle-to-system (V2S) messaging requirements and interface control documents (ICDs) between the base vehicle and added subsystems.
• Interpret OEM International® and ND Defense® electrical schematics, body builder/upfitter guidelines, and datalink specifications to identify available interfaces.
• Capture and document customer system, hardware, and software requirements with full traceability.
• Perform bench-level and vehicle-level integration, testing, and troubleshooting to verify the integrated system meets customer and contractual requirements.
• Develop and execute test plans and procedures; document results in formal test reports.
• Interface with cross-functional teams, suppliers, and customer representatives in design reviews, program meetings, and technical exchanges.
• Support proposal development by providing technical input, level-of-effort estimates, and electrical integration assessments for new programs.

Required Qualifications

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Mechanical Engineering, or Computer Science.
• Must be a U.S. citizen (ITAR requirement).
• Minimum 3 years of post-graduate working experience in vehicle electrical integration (automotive, commercial truck, or military vehicle level preferred).
• Experience with vehicle network CAN communications (J1939 protocol).
• Experience integrating equipment or kits into an existing vehicle electrical architecture, including interpreting OEM wiring and body builder/upfitter documentation.
• Able to read, understand, and create electrical schematics, with a solid understanding of electrical and electronics fundamentals.
• Familiarity with electrical load analysis, power distribution, and circuit protection.
• Excellent verbal, written, and interpersonal skills, including the ability to write concise technical reports such as interface control documents and test procedures.
• Initiative to work independently and manage multiple assignments simultaneously.
• Ability to work in, on, under, and around large vehicles.

Preferred Qualifications

• Experience with military vehicle electrical systems or defense vehicle upfitting/integration programs.
• Familiarity with MIL-STD specifications applicable to electrical systems (e.g., MIL-STD-461, MIL-STD-1275, MIL-STD-1553).
• Proficiency with CAD tools for electrical design (e.g., AutoCAD Electrical, CATIA Electrical, Capital Harness, Mentor Graphics).
• Experience with vehicle diagnostic tools and CAN bus analysis software (e.g., CANalyzer, PCAN, Vehicle Spy).
• Knowledge of International® truck platforms, Diamond Logic® programming, or Navistar body builder documentation.
• Working knowledge of SAE standards (J1939, J1708/J1587).
