About the Role

Apex is seeking a Harness Design Engineer to join the team developing 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 connectors, backshells, wires, and shielding materials 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 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 Bill of Materials, Interface Control Documents, and manufacturing drawings.
  • Ensure designs meet aerospace standards including IPC/WHMA-A-620, SMC-S-020, and NASA-STD-8739.4.
  • Maintain records for design iterations, compliance checks, and testing results.
  • Support harness installation, integration, troubleshooting, and problem resolution during spacecraft assembly and testing.

Requirements

  • 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 such as Altium and Rapid Harness.
  • Proficiency in mechanical CAD tools such as NX and Teamcenter.
  • Experience with harness manufacturing processes, vendor interaction, prototyping, and production support.
  • Knowledge of spaceflight standards such as NASA and ESA, and quality compliance requirements including IPC/WHMA-A-620, MIL-STD-810, SMC-S-020, and 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 multidisciplinary teams.
  • U.S. Person status required to access export controlled data.
