What does a freelance wiring harness designer do?

A Freelance Wiring Harness Designer specializes in creating the electrical wiring systems that connect various components within machines, vehicles, or electronic devices. Their responsibilities include designing schematics, selecting appropriate materials, and ensuring that the harnesses meet safety and industry standards. Working independently or on a contract basis, they often collaborate with engineers and manufacturers to customize solutions for specific projects. Freelancers in this field must stay updated with the latest technologies and industry regulations to deliver efficient and reliable designs.

What are the key skills and qualifications needed to thrive as a freelance wiring harness designer?

To thrive as a Freelance Wiring Harness Designer, you need expertise in electrical engineering principles, schematic interpretation, and harness layout, often supported by a degree in electrical engineering or related experience. Familiarity with CAD software (such as AutoCAD or SolidWorks), wiring harness design tools, and industry standards like IPC/WHMA-A-620 is typically required. Strong problem-solving, attention to detail, and effective client communication set standout designers apart. These skills ensure that harnesses are safe, reliable, and tailored to project specifications, fostering client trust and successful project outcomes.

What are some common challenges faced by freelance wiring harness designers, and how can they be managed?

Freelance wiring harness designers often encounter challenges such as managing varying client specifications, tight project deadlines, and limited access to proprietary design tools or software. To address these, it's important to establish clear communication with clients regarding requirements and timelines, stay organized with project management tools, and invest in industry-standard CAD software or seek cost-effective alternatives. Networking with other professionals and staying updated on latest design standards can also help ensure successful project delivery and client satisfaction.

What is the difference between Freelance Wiring Harness Design vs Electrical Engineer?

AspectFreelance Wiring Harness DesignElectrical Engineer
CredentialsTypically requires technical training or certification in wiring or electrical systemsRequires a bachelor's degree in electrical engineering or related field
Work EnvironmentOften self-employed, working remotely or on-site for clientsUsually employed by companies, working in offices or labs
Industry UsageUsed in automotive, aerospace, and manufacturing sectors for custom wiring solutionsDesigns electrical systems for products, infrastructure, and machinery

Freelance Wiring Harness Design focuses on creating custom wiring solutions for clients, often independently, while Electrical Engineers design broader electrical systems within organizations. Both roles require technical knowledge, but differ in scope, employment setting, and project types.

Job description

Please Note: To conform with the United States Government Space Technology Export Regulations, the applicant must be a U.S. citizen, lawful permanent resident of the U.S., conditional resident, asylee or refugee (protected individuals as defined by 8 U.S.C. 1324b(a)(3)), or eligible to obtain the required authorizations from the U.S. Department of State.

At CesiumAstro, we are developers and pioneers of out-of-the-box communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We take pride in our dynamic and cross-functional work environment, which allows us to learn, develop, and engage across our organization. If you are looking for hands-on, interactive, and autonomous work, CesiumAstro is the place for you. We are actively seeking passionate, collaborative, energetic, and forward-thinking individuals to join our team.

We are looking to add a Wire Harness Design Engineer II 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.

KEY RESPONSIBILITIES
  • Assist the design and development of high-complexity wire harnesses across space and airborne systems and associated GSE.
  • Adherence to requirements and workmanship standards for harness design
  • Leverage preferred parts listing based on component reliability, availability, and manufacturability
  • Inform the definition of design 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 the box, subsystem, and platform levels.
  • Proliferate design standards and contribute to process improvements to advance the maturity of the wire harness discipline.
  • 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; serve as the subject matter expert for interconnect systems.
JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS
  • Bachelor of Science degree in Electrical Engineering or Mechanical Engineering from an accredited university. 
  • 2 years of relevant industry or university research experience.
  • Familiarity in 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 a high level of accuracy in design documentation and technical specifications.
  • Excellent written and spoken communication skills.
