Supplier Development Engineer, Power Electronics (Starlink)

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, POWER ELECTRONICS (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 electronics, including power conversion modules, power supply units, and critical power 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 power electronics 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 power electronics design and manufacturing, along with the ability to provide technical guidance on power conversion topologies, semiconductors, and thermal systems. The Supplier Development Engineer, Power Electronics will be responsible for executing supplier strategies focused on power conversion modules, power supply units, and associated power components.

This position will have significant technical influence across Starlink engineering, quality, and supply chain teams.

RESPONSIBILITIES

: Own end-to-end supplier development for the power electronics and power conversion portfolio within the Starlink User Terminal Bill of Materials, spanning strategic supplier selection, new product introduction (NPI), qualification, production ramp, and reactive quality support Engage early with suppliers on selection, equipment selection, and process engineering to properly set up high-volume manufacturing programs by ensuring material and process corners are fully characterized and completed Assess supplier manufacturing capabilities, process controls, and technical readiness for high-volume production of power electronics, including silicon, silicon carbide (SiC), and gallium nitride (GaN) based designs, power conversion topologies, magnetics, capacitors, and thermal management solutions Lead new product introduction (NPI) activities, production part approval process (PPAP), first article inspections (FAI), production rate ramps, and reliability campaigns to enable full-rate, high-volume manufacturing Develop and execute robust qualification plans tailored to power electronics, including power cycling, thermal validation, highly accelerated life testing (HALT), highly accelerated stress screening (HASS), corner-case testing, gate drive validation, and electromagnetic interference and electromagnetic compatibility (EMI/EMC) compliance Create and standardize qualification protocols across the power electronics supply base, including equipment buy-off checklists, factory acceptance tests (FAT), site acceptance tests (SAT), and consistent reliability demonstration methods 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 power electronics failure modes such as metal-oxide-semiconductor field-effect transistor (MOSFET) and gallium nitride (GaN) device failures, capacitor degradation, thermal runaway, solder fatigue, bond wire lift, and
