CesiumAstro is seeking a Wire Harness Design Engineer II to join their team in Austin, TX. The company develops communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms.
In this role, you will design critical power, digital, analog, and RF interconnects that integrate subsystems into complete platforms. You will take full ownership of wire harness designs from conception through integration and test, including schematic development, cable routing, connector selection, and harness assembly drawings. The work is highly collaborative, with close partnership between electrical engineers, mechanical engineers, and harness assembly technicians.
Key responsibilities include:
- Design and develop high-complexity wire harnesses for space and airborne systems and ground support equipment
- Ensure adherence to requirements and workmanship standards for harness design
- Leverage preferred parts listings based on component reliability, availability, and manufacturability
- Inform 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 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

- Familiarity with harness design tools such as Capital Essentials or Zuken E3
- Basic understanding of electrical/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
- Exposure to industry standards and regulations related to wire harness design, such as IPC-WHMA-A-620 and/or NASA-STD 8739.4A
- Awareness of high-reliability components such as D38999, Micro-D, Nano-D connectors and M227569/M27500 series of wire
- Detail-oriented approach 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 assembling wire harnesses and necessary tooling
