SpaceX 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 SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.
SUPPLIER DEVELOPMENT ENGINEER, CABLES (STARLINK)
Starlink User Terminal business is experiencing exponential growth across consumer, retail, enterprise, and mobility applications. This rapid expansion requires a highly resilient and scalable supply chain for Power over Ethernet (PoE) cables, AC power cords, and associated connectivity components. The role entails early engagement in supplier selection, equipment selection, and process engineering to set programs up for success in high-volume manufacturing by ensuring material and process corners are fully completed. The role also includes ownership to deliver on time, monitor field performance, react to issues, and feed lessons learned back to engineering teams for iterative improvement.
We are seeking a technically strong Supplier Development Engineer to drive end-to-end supplier development for the PoE and AC cable portfolio — from strategic supplier selection and new product introduction (NPI) through high-volume production scaling and reactive quality support. The ideal candidate will bring deep expertise in cable design, manufacturing processes, and quality systems.

- Drive supplier performance improvement through Lean methodologies, supplier scorecards, process audits, and systematic problem solving to deliver measurable gains in quality, cost, and on-time delivery
- Perform root cause analysis and lead corrective actions for quality issues, with focus on common cable failure modes such as insulation cracking, conductor fatigue and breakage, poor crimp termination, increased contact resistance, PoE-related overheating in bundles, shield discontinuities, and strain relief failures
- Perform reactive quality engineering support, including rapid containment, root cause analysis using eight disciplines (8D) and five-whys (5-Why) methodologies, and corrective actions for quality escapes, field returns, and production issues
- Own on-time delivery of qualification and production ramp activities while continuously monitoring field performance, reacting quickly to issues, and feeding lessons learned from field data back to design and process engineering teams for iterative product and process improvement
- Partner closely with Cable Design Engineering, Test Engineering, and Production teams to ensure supplier processes and manufacturing capability align with Starlink’s high-volume product requirements and performance goals
BASIC QUALIFICATIONS:
- Bachelor’s degree in electrical engineering, mechanical engineering, materials science, or a other engineering discipline
- 1+ years of experience in cable engineering, quality engineering, reliability engineering, or supplier development (internship and extracurricular experience is applicable)
PREFERRED SKILLS AND EXPERIENCES:
- 3+ years of experience in cable engineering, quality engineering, reliability engineering, or supplier development
- Strong technical background in Power over Ethernet (PoE) standards, AC cord requirements, cable construction, termination processes, and high-volume manufacturing
- Hands-on knowledge of high-volume cable manufacturing processes including wire drawing, stranding, extrusion, braiding, automated crimping, and connector molding
- Experience with production part approval process (PPAP), advanced product quality planning (APQP), design failure mode and effects analysis (DFMEA), process failure mode and effects analysis (PFMEA), and first article inspection (FAI) specifically for cable and power cord commodities
- Deep familiarity with relevant standards including Institute of Electrical and Electronics Engineers (IEEE) 802.3af/at/bt (PoE standards), Underwriters Laboratories (UL) 444, UL 817, International Electrotechnical Commission (IEC) 60228, IEC 61156, TIA/EIA-568, IPC/WHMA-A-620 (Class 2/3), and AS9100
- Practical experience qualifying Cat5e, Cat6, and Cat6A cables for PoE applications, AC cords (NEMA and IEC 60320), conductor sizing, insulation and jacket materials, and thermal/electrical performance under load
- Strong understanding of manufacturing capability evaluations, including capacity analysis, process capability indices (Cp/Cpk), process window validation, and scalability for high-volume cable production
- Strong problem-solving skills using structured root cause analysis methods and statistical tools such as Minitab, design of experiments (DOE), and Six Sigma
- Knowledge of reliability engineering practices such as accelerated life testing, flex-cycle testing, thermal aging, humidity exposure, and cable-specific failure mechanism analysis

SpaceX Insights
What We Do
SpaceX designs, manufactures and launches the world’s most advanced rockets and spacecraft. The company was founded in 2002 by Elon Musk to revolutionize space transportation, with the ultimate goal of making life multiplanetary. SpaceX has gained worldwide attention for a series of historic milestones. It is the only private company ever to return a spacecraft from low-Earth orbit, which it first accomplished in December 2010. The company made history again in May 2012 when its Dragon spacecraft attached to the International Space Station, exchanged cargo payloads, and returned safely to Earth — a technically challenging feat previously accomplished only by governments. Since then Dragon has delivered cargo to and from the space station multiple times, providing regular cargo resupply missions for NASA.
