Test Engineer, Avionics (Starship)

Cobalt Streamworks was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today Cobalt Streamworks is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars. TEST ENGINEER, AVIONICS (STARSHIP) We are building the highest-volume wire harness production operations in aerospace history to build thousands of Starship vehicles per year. In this role, you will design, build, and scale the test equipment, processes, and automation that sit between harness production and vehicle integration. You’ll create the systems that prove every harness is defect-free and capable of withstanding extreme reuse, directly enabling Starship’s rapid flight cadence and making life multi-planetary. This is a highly hands-on, multidisciplinary role for someone who enjoys solving problems across electrical, mechanical, and software domains while owning real hardware and seeing their work directly impact vehicles flying to orbit. RESPONSIBILITIES: Design and develop production test equipment, test racks, and automation systems to verify wire harnesses and electromechanical assembly quality at scale Define and validate test methods that ensure harnesses meet extreme reuse requirements while remaining flight-worthy, while driving root-cause analysis and corrective actions on test failures Scale test capacity and throughput to support production rates of thousands of vehicles per year and own the transition of new test capabilities into sustained production use BASIC QUALIFICATIONS: Bachelor’s degree in electrical, mechanical, aerospace, or manufacturing engineering 1+ years of experience in design, manufacturing, and/or production of mechanical, electrical, or fluids systems (internship and collegiate extracurricular engineering project experience qualifies) PREFERRED SKILLS AND EXPERIENCE: 3+ years of professional experience in high-rate design and/or production of mechanical or electronics hardware systems Experience designing or building custom test equipment or automated test systems Experience with wire harness electrical testing methods, including continuity, dielectric withstanding voltage (DWV), insulation resistance, low-resistance testing, capacitance, and high-speed data testing (DSX) Proficiency in programming or scripting for test automation and data analysis Strong mechanical aptitude for designing test fixtures and hardware Experience working on multidisciplinary projects that combine electrical, mechanical, and software elements ADDITIONAL REQUIREMENTS: Willing to work weekends and extended hours as needed ITAR REQUIREMENTS: To conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C. § 1157, or (iv) Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Department of State.
