Supplier Development Engineer, SMT (Starlink) at SpaceX · LumiJobs

Responsibilities

Own end-to-end supplier development for the WiFi router and wireless module 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 WiFi routers, including printed circuit board (PCB) assembly for radio frequency (RF) circuits, antenna integration and tuning, radio frequency (RF) shielding, thermal solutions, and automated testing systems
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 WiFi routers, including radio frequency (RF) conducted and radiated testing, over-the-air (OTA) throughput validation, multiple-input multiple-output (MIMO) and multi-user multiple-input multiple-output (MU-MIMO) performance verification, beamforming calibration, thermal throttling assessment, and electromagnetic interference and electromagnetic compatibility (EMI/EMC) compliance
Create and standardize qualification protocols across the WiFi router 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 WiFi router failure modes such as radio frequency (RF) desense, antenna detuning, signal degradation due to poor shielding, thermal-induced WiFi instability, packet error rate increases, and interference from power electronics
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 WiFi Router Design Engineering, Radio Frequency (RF) Test Engineering, and Production teams to ensure supplier processes and manufacturing capability align with Starlink’s high-volume product requirements and performance goals

Qualification

Required

Bachelor’s degree in electrical engineering, computer engineering, or other engineering discipline
1+ years of experience in WiFi or radio frequency (RF) engineering, quality engineering, reliability engineering, or supplier development (internship and extracurricular experience is applicable)

Preferred

3+ years of experience in WiFi or radio frequency (RF) engineering, quality engineering, reliability engineering, or supplier development
Strong technical background in Institute of Electrical and Electronics Engineers (IEEE) 802.11 WiFi standards, radio frequency (RF) hardware, antenna systems, and high-volume manufacturing
Hands-on knowledge of high-volume WiFi router manufacturing processes including surface mount technology (SMT) assembly for radio frequency (RF) circuits, antenna tuning and integration, radio frequency (RF) shielding application, automated functional testing, and thermal management solutions
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 WiFi routers and wireless modules
Deep familiarity with relevant standards including Institute of Electrical and Electronics Engineers (IEEE) 802.11ax (WiFi 6), 802.11be (WiFi 7), Federal Communications Commission (FCC) Part 15, European Telecommunications Standards Institute (ETSI) EN 300 328, International Electrotechnical Commission (IEC) 62368-1, IPC-A-610, and AS9100
Practical experience qualifying dual-band and tri-band routers, multiple-input multiple-output (MIMO) antenna arrays, orthogonal frequency-division multiple access (OFDMA), 1024-quadrature amplitude modulation (QAM) and 4096-QAM schemes, channel bandwidths up to 320 megahertz (MHz), and beamforming technologies
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, thermal cycling, humidity exposure, and radio frequency (RF) performance drift analysis
