Harness Design Engineer

Wanna join the adventure?

Loft Orbital is redefining how satellites are built and deployed. We provide a fast, simple, and reliable path to orbit by combining standardized space vehicles, mission-specific payload integration, and end-to-end mission execution.

As a Harness Design Engineer, you’ll help design the electrical harnesses that connect spacecraft systems, avionics, payloads, and test equipment. You’ll work across electrical systems, mechanical engineering, manufacturing, and integration & test to turn electrical interfaces into reliable, production-ready hardware.

This is a great opportunity for an earlier career candidate with a strong electrical engineering foundation and an interest in developing expertise in spacecraft harness design.

• Design electrical harnesses for spacecraft, payloads, and test systems.
• Translate schematics, ICDs, pinouts, and electrical interfaces into harness designs.
• Create harness schematics and 3D harness assemblies using Creo.
• Develop manufacturing drawings, bills of material, and harness documentation.
• Support harness fabrication, inspection, integration, testing, and troubleshooting.
• Contribute to harness libraries, design standards, and continuous improvement.

• Bachelor’s degree in electrical engineering, aerospace engineering, or a related field
• Strong foundation in electrical engineering, circuits, electronics, and electrical interfaces.
• Ability to read electrical schematics, wiring diagrams, pinouts, and interface documentation.
• Strong attention to detail and interest in precise, hands-on engineering work.
• Ability to learn new engineering tools and collaborate across electrical, mechanical, manufacturing, and test teams.
• Strong problem-solving, communication, and organizational skills.

• Experience with Creo, SolidWorks, CATIA, or another 3D CAD system.
• Experience with electrical schematics, wiring diagrams, block diagrams, or connectivity data.
• Familiarity with connectors, wires, cables, shielding, grounding, strain relief, or EMI/EMC.
• Hands-on experience with electronics, PCBs, soldering, crimping, electrical test equipment, or hardware integration.
• Coursework or project experience in embedded systems, RF, signal integrity, power electronics, or high-speed digital design.

• Equity, we want you to have an active role in our success
• Up to 35 days of Paid Time Off (vacations & RTT ) and flexible working hours, we want you to be at your best
• Health and life insurance, we care about your health
• Lunch Vouchers, because let’s be honest, we love food! (we even have a slack channel about it #loft-gourmand)
• Cross-office travel opportunities between San Francisco, Colorado, and Toulouse to learn from our differences
• Company and team off-sites and many other events to work & celebrate together
• Relocation assistance to Toulouse when applicable

 *Research shows that while men apply to jobs where they meet an average of 60% of the criteria, women and other underrepresented people tend to only apply when they meet 100% of the qualifications. At Loft, we value respectful debate and people who aren’t afraid to challenge assumptions.  We strongly encourage you to apply, even if you don’t check all the boxes.

Who We Are

Loft: Space Made Simple. 

Founded in 2017, Loft provides governments, companies, and research institutions with a fast, reliable, and simple way to deploy missions in orbit.

We integrate, launch, and operate spacecraft, offering end-to-end missions as a service across Earth observation, IoT connectivity, on-orbit AI, national security missions, and more. Leveraging our existing space infrastructure and an extensive inventory of satellite buses, Loft is reducing years-long integration and launch timelines to months. With more than 30 missions flown, Loft’s flight heritage and proven technologies enable customers to focus on their mission objectives.

With a growing fleet on track to reach 30 satellites by 2027, we are scaling up quickly across our offices in San Francisco, CA | Golden, CO | and Toulouse, France to meet accelerating demand for space infrastructure.
