Harness Design Engineer

K2 is building the largest and highest-power satellites ever flown, unlocking performance levels previously out of reach across every orbit.Backed by $450M from leading investors including Altimeter Capital, Redpoint Ventures, T. Rowe Price, Lightspeed Venture Partners, Alpine Space Ventures, and others – with an additional $500M in signed contracts across commercial and US government customers – we’re mass-producing the highest-power satellite platforms ever built for missions from LEO to deep space. The rise of heavy-lift launch vehicles is shifting the industry from an era of mass constraint to one of mass abundance, and we believe this new era demands a fundamentally different class of spacecraft. Engineered to survive the harshest radiation environments and to fully capitalize on today’s and tomorrow’s massive rockets, K2 satellites deliver unmatched capability at constellation scale and across multiple orbits. With multiple launches planned through 2026 and 2027, we're Building Bigger to develop the solar system and become a Kardashev Type II (K2) civilization. If you are a motivated individual who thrives in a fast-paced environment and you're excited about contributing to the success of a groundbreaking Series C space startup, we’d love for you to apply. The Role You willbe responsible for harness and wiringsystem design, analysis,testingand integration on some of the largest, most powerful, rapidlydesignedand manufactured satellites. You will have the unique opportunity tocollaboratewith a cross functional team of engineersand own tradesto reducecost,increaseintegration rate,anddecreasemassof bus and payload harnessing.You will be the Responsible Engineer forharnesssystem design and components such as connectors, wire and cable,instrumentation,andheaters. You will helpestablishproduction testrequirementsand support vehicleavionics integration to enablehigh-rateproduction andconstellation launch cadence. In your first two years, you will have qualified hardware for flight, completed avionics integration on the satellite bus, and flown yourhardware through intense LEO, MEO and GEO environments. Responsibilities Serve as Responsible Engineer for harness system design for bus avionics, mechanisms, RF systems, and payloads across the Mega and Giga satellites Define interface control documents for avionics boxes and bulkheads to optimize system diagrams and schematics Design, analyze,and release harnessing and secondary mounting hardwareinCADand production drawingsbased on system schematicsand vehicle layout Drive design tradesto reduce costandselectharness components such as connectors,contacts,wire/cables,shield braid,heaters, RTDs and more Collaborate closely with the manufacturing engineering and technicians on the harness and electro-mechanical subassembly teamstosolve in process issues and ensure high reliability Execute development andqualification testingof harness components and assemblies for critical space missionsin MEO and GEO orbits Collaborate closely with the cross functionalengineeringteamsto capture requirements, lead design trades, and integrate the design into the spacecraft systems Effectively manage and communicate project plan, milestones, and schedule execution Qualifications Bachelor’s degree in aerospace, mechanical, or electrical engineering or any equivalent combination of education and experience 2+ years of experience in electrical harness design, routing, production, and system integration Ability to work in a fast-paced and high velocity start-up atmosphere Creative problem solver that can assess risk and make collaborative design and development decisions Nice to Have Hands-on experience with environmental testing for space harnessing such as thermal, thermal vacuum, vibration, shock, radiation, and EMI/EMC testing per SMC-S-016 Competence with electrical test equipment (multimeters, oscilloscopes, network analyzers, etc.) Strong presentation experience in highly technical design forums and reviews (Preliminary Design Reviews, Critical Design Reviews, Flight Readiness Reviews, etc.) Proficient with NX or similar CAD software including electrical harness routing Experience with practical application of GD&T and FEA Compensation and Benefits Base salary range for this role is $120,000- $160,000+ equity in the company Salary will be based on several factors including, but not limitedto: knowledge and skills, education, and experience level Comprehensive benefits package paid time off, medical/dental/vision coverage, life insurance, paid parental leave, and many otherperks If you need a reasonable accommodation as part of your application for employment or interviews with us, please let us know. Export Compliance As defined in the ITAR, “U.S. Persons” include U.S. citizens, lawful permanent residents (i.e., Green Card holders), and certain protected individuals (e.g., refugees/asylees, American Samoans). Please consult with a knowledgeable advisor if you are unsure whether you are a “U.S. Person.” The person hired for this role will have access to information and items controlled by U.S. export control regulations, including the export control regulations outlined in the International Traffic in Arms Regulation (ITAR). The person hired for this role must therefore either be a “U.S. person” as defined by 22 C.F.R. § 120.15 or otherwise eligible for a federally issued export control license.
