Wire Harness Design Engineer II Verified today

CesiumAstro develops communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We are seeking a Wire Harness Design Engineer II to join our Austin, TX team.

In this role, you will design the critical power, digital, analog, and RF interconnects that integrate subsystems into complete platforms. You will own wire harness designs end-to-end: from defining specifications through schematic development, cable routing, connector selection, and assembly drawings. You will work directly with electrical engineers, mechanical engineers, and harness assembly technicians.

Responsibilities

• Design and develop high-complexity wire harnesses for space and airborne systems and ground support equipment.
• Adhere to requirements and workmanship standards for harness design.
• Leverage preferred parts lists based on component reliability, availability, and manufacturability.
• Define design for EMI / EMC compliance, radiation tolerance, and space charging environments.
• Collaborate cross-functionally to align harness designs 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 in the wire harness discipline.
• Work with suppliers and contract manufacturers to manage supply chain, build quality, and schedule.
• Present technical solutions in internal and external design reviews as subject matter expert for interconnect systems.

Required Qualifications

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

Preferred Experience

• Experience designing for aerospace environments.
• Conceptual understanding of wire harness assembly and necessary tooling.

Full-time employment includes company stock options and benefits: health, dental, vision, HSA, FSA, life, disability, and retirement plans.
