Senior Wire Harness Design Engineer II Verified today

CesiumAstro develops communication systems for satellites, UAVs, launch vehicles, and airborne platforms. The Skylark product line focuses on active phased array antennas (AESA) for terrestrial and airborne applications, spanning high-power ground terminals and commercial connectivity solutions.

This role focuses on designing the critical power, digital, analog, and RF interconnects that turn boxes into systems. You will take full ownership of wire harness designs, including schematic development, cable routing, connector selection, and harness assembly drawings. The environment is highly collaborative, working with electrical engineers, mechanical engineers, and harness assembly technicians.

You will guide the full design process, from defining initial specifications through integration and test. You will participate in design reviews, providing technical expertise and recommendations to enhance the performance and reliability of wire harness systems.

Key Responsibilities

• Design and develop high-complexity wire harnesses across space and airborne systems and associated ground support equipment.
• Define requirements and workmanship standards for harness design.
• Establish preferred parts listing based on component reliability, availability, and manufacturability.
• Define designs for EMI/EMC compliance, radiation tolerance, and space charging environments.
• Collaborate cross-functionally to ensure harness designs align with system-level requirements for performance, manufacturability, and reliability.
• Support integration, testing, and troubleshooting of harness systems at box, subsystem, and platform levels.
• Contribute to design standards and process improvements to advance wire harness discipline maturity.
• Work directly with suppliers and contract manufacturers to manage supply chain, build quality, and schedule outcomes.
• Present technical solutions in internal and external design reviews as the subject matter expert for interconnect systems.

Requirements

• Bachelor of Science degree in Electrical Engineering or Mechanical Engineering from an accredited university.
• 6 years of relevant industry or university research experience.
• Proficiency in harness design tools such as Capital Essentials or Zuken E3.
• Solid understanding of electrical and mechanical engineering principles, wire routing, controlled impedance, cable shielding, and electromagnetic compatibility (EMC) considerations.
• Ability to conduct thorough analysis and testing of wire harness designs to ensure compliance with applicable industry standards, safety regulations, and performance requirements.
• Knowledge of industry standards such as IPC-WHMA-A-620 and NASA-STD 8739.4A.
• Skilled with high-reliability components such as D38999, Micro-D, Nano-D connectors and M227569/M27500 series wire.
• Detail-oriented approach with high accuracy in design documentation and technical specifications.
• Excellent written and spoken communication skills.
• Aerospace industry experience.

Preferred Experience

• Experience designing for space environments.
• Hands-on experience assembling wire harnesses.
• IPC-WHMA-A-620 harness build certification.
