Electrical Systems Engineer

Responsibilities

• You Will:
• Contribute to the architecture and design of electrical subsystems, ensuring alignment with overall machine requirements and operational goals.
• Define, maintain, and manage system and subsystem requirements, ensuring clear traceability from top-level objectives to implemented hardware.
• Develop and maintain Interface Control Documents (ICDs) that define electrical, controls, and mechanical interfaces between subsystems and suppliers.
• Support verification planning and execution, ensuring requirements have clear verification methods and participating in testing activities.
• Work hands-on during hardware bring-up and prototyping, helping diagnose and resolve issues across electrical hardware, controls systems, and subsystem interfaces.
• Collaborate closely with electrical, controls, mechanical, and test teams to ensure designs function correctly within the overall machine.
• Support integration of new hardware and subsystems during development and commissioning.
• Contribute to system documentation and engineering processes, including requirements management, design reviews, and integration planning.
• Required Skills:
• Bachelor's or Master's degree in Electrical Engineering or a related field.
• 3+ years of experience in electrical systems engineering, integration, test, or hardware development.
• Experience contributing to system or subsystem architecture, including defining electrical subsystems and their interactions.
• Experience developing and managing technical requirements and Interface Control Documents (ICDs).
• Ability to read and interpret electrical schematics, wiring diagrams, and interconnect documentation.
• Hands-on experience with hardware bring-up, troubleshooting, and root cause analysis using standard lab instrumentation such as oscilloscopes, DMMs, and logic or spectrum analyzers.
• Experience working with cross-disciplinary engineering teams including electrical, controls, mechanical, and test.
• Strong technical documentation and communication skills, including the ability to clearly capture requirements, interfaces, and design decisions.
• Experience working with hardware suppliers or external partners to define technical requirements and review deliverables.

Requirements

• Experience in aerospace, automotive, robotics, energy systems, or other safety-critical, high-reliability industries.
• Familiarity with large-scale electrical hardware systems, including power distribution, sensing, and controls integration.
• Knowledge of high-voltage or high-current electrical systems, including grounding, protection, and EMI/EMC considerations.
• Experience with requirements management and PLM tools such as Flow, Jama, DOORS, Teamcenter, or Confluence.
• Exposure to system safety and reliability methods, including FMEA, FMECA, or fault analysis.
• Experience supporting or executing system-level integration testing, including instrumentation, automation, and data analysis.
• Familiarity with electrical interconnect systems and harness manufacturing standards
