CesiumAstro is an American company founded in Austin in 2017 that builds active phased array communications payloads for satellites, aircraft and defence platforms. Its systems are software-defined and electronically steered, which lets a moving platform track several links at once without mechanical antennas, and the company manufactures them in house rather than integrating third-party subsystems. It sells mainly to defence customers and satellite operators, has raised venture funding from investors including Airbus Ventures and Lightspeed, and operates facilities in Austin, Colorado and the United Kingdom.

We are looking to add a Senior Wire Harness Design Engineer to our team. If you enjoy working in a startup environment and are passionate about developing leading-edge hardware for satellites, spacecraft, and aerospace systems, we would like to hear from you.

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

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

JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS

  • Bachelor of Science degree in Electrical Engineering from an accredited university.
  • 5 years of relevant industry or university research experience.
  • Proficiency in harness design tools such as RapidHarness.
  • Solid understanding of electrical 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 and regulations related to wire harness design, such as IPC-WHMA-A-620 and ISO 9001.
  • Extensive hands-on experience with lab instruments such as oscilloscopes, spectrum analyzers, and electronic loads.
  • Detail-oriented approach with a high level of 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.
