About the Role

Apex is seeking a Harness Design Engineer to join our team developing cutting-edge space systems for government and commercial customers. You will design, analyze, and verify electrical harnesses for spacecraft, satellites, rovers, and aerospace applications, meeting rigorous spaceflight standards and ensuring system integrity in harsh space environments.

Responsibilities

• Develop detailed designs for electrical harnesses, including wiring diagrams, schematics, and 3D routing models
• Select suitable connectors, backshells, wires, and shielding materials specifically designed for space environments
• Work with systems and mechanical engineering teams to ensure harness designs meet system requirements and integration needs
• Perform electrical analyses, including voltage drop, current derating, signal integrity, and thermal effects to validate harness performance
• Ensure designs comply with EMI/EMC requirements and spaceflight standards such as NASA and ESA
• Conduct environmental assessments to ensure harnesses are suited for extreme space conditions, including thermal, radiation, and mechanical stresses
• Develop comprehensive test plans and procedures for harness qualification, acceptance, and environmental testing
• Collaborate with testing teams to validate designs under simulated space conditions such as thermal vacuum, vibration, and radiation testing
• Address performance issues identified during testing and implement design improvements
• Generate detailed design documentation, including Bills of Materials, Interface Control Documents, and manufacturing drawings
• Ensure all designs meet aerospace standards including IPC/WHMA-A-620, SMC-S-020, and NASA-STD-8739.4
• Maintain accurate records for design iterations, compliance checks, and testing results
• Support harness installation, integration, troubleshooting, and problem resolution during spacecraft assembly and testing phases

Requirements

• U.S. Person status required to access export controlled data
• Bachelor's or Master's degree in Electrical Engineering, Aerospace Engineering, or related field
• 3+ years of experience in electrical harness design for aerospace, space systems, or related industries
• Strong understanding of electrical design principles, including grounding, shielding, power distribution, and signal integrity
• Proficiency in electrical CAD tools (e.g., Altium, Rapid Harness) and mechanical CAD tools (e.g., NX, PLM in Teamcenter)
• Experience with harness manufacturing processes, including vendor interaction, prototyping, and production support
• Knowledge of spaceflight standards (NASA, ESA) and quality compliance requirements (IPC/WHMA-A-620, MIL-STD-810, SMC-S-020, NASA-STD-8739.4)
• Ability to interpret electrical schematics and technical drawings with keen attention to detail
• Strong problem-solving skills and ability to work collaboratively in a multidisciplinary team environment
