Supplier Development Engineer, Photovoltaics (Starlink)

SpaceX • Bastrop, TX

16h • Onsite

About The Position

The Starlink User Terminal business is experiencing exponential growth, requiring a resilient and scalable supply chain for solar cells, wafers, ingots, and polysilicon. This role involves early engagement in supplier and equipment selection, and process engineering to ensure success in high-volume manufacturing. The position also includes ownership of on-time delivery, monitoring field performance, addressing issues, and feeding 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 and manufacturing bring-up across the photovoltaic supply chain, with a strong focus on solar cell fabrication and upstream polysilicon, ingot, and wafer supply. The ideal candidate will possess deep expertise in solar cell manufacturing processes and provide technical guidance on high-efficiency cell technologies. This position will have significant technical influence across Starlink engineering, quality, and supply chain teams, with extreme end-to-end ownership from early engagement through production scaling and field performance.

Requirements

• Bachelor’s degree in materials science, chemical engineering, electrical engineering, or a other engineering discipline
• 1+ years of experience in solar photovoltaic manufacturing, crystalline silicon supply chain, or supplier development (internship and extracurricular experience is applicable)

Nice To Haves

• 3+ years of experience in solar photovoltaic manufacturing, crystalline silicon supply chain, or supplier development
• Strong technical background in solar cell fabrication and upstream silicon processes
• Hands-on experience bringing up solar cell manufacturing lines, with preference for advanced high-efficiency technologies such as Tunnel Oxide Passivated Contact (TOPCon), Heterojunction Technology (HJT), Passivated Emitter and Rear Cell (PERC), and Interdigitated Back Contact (IBC)
• Deep knowledge of crystalline silicon photovoltaic processes including polysilicon refining, ingot crystallization (Czochralski or directional solidification), wafer slicing, texturing, diffusion, passivation, metallization, and cell testing
• Experience with production part approval process (PPAP), advanced product quality planning (APQP), design failure mode and effects analysis (DFMEA), and process failure mode and effects analysis (PFMEA)
• Strong understanding of manufacturing capability assessment, yield improvement, and scaling high-volume photovoltaic production
• Familiarity with relevant industry standards including International Electrotechnical Commission (IEC) 61215, IEC 61730, and Underwriters Laboratories (UL) 1703
• Strong problem-solving skills using structured root cause analysis methods and statistical tools such as Minitab, design of experiments (DOE), and Six Sigma
• Excellent written and verbal communication skills with the ability to distill complex technical topics into clear one-pagers and presentations
• Demonstrated ability to influence cross-functional teams and suppliers in a fast-paced, high-growth environment

Responsibilities

• Own end-to-end supplier development and manufacturing bring-up for the photovoltaic supply chain within the Starlink User Terminal Bill of Materials, spanning polysilicon, ingots, wafers, solar cells, and module integration
• 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
• Lead the bring-up of solar cell manufacturing lines while also supporting upstream wafer, ingot, and polysilicon supply chain development to enable high-volume module output
• Assess supplier manufacturing capabilities with strong emphasis on solar cell fabrication processes including texturing, diffusion, passivation, anti-reflective coating, metallization, and cell testing, along with upstream silicon material processes
• Lead new product introduction (NPI) activities, production part approval process (PPAP), first article inspections (FAI), production rate ramps, and qualification campaigns to enable full-rate, high-volume manufacturing
• Develop and execute robust qualification plans covering polysilicon purity, ingot quality, wafer specifications, solar cell efficiency, reliability, and overall module performance
• Implement artificial intelligence (AI) solutions for process control, defect detection, yield optimization, and predictive analytics in solar cell manufacturing
• Create and standardize qualification protocols across the 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, yield, cost, and on-time delivery
• 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 Solar Cell Design Engineering, Process Engineering, Test Engineering, and Production teams to ensure supplier processes and manufacturing capability align with Starlink’s aggressive high-volume product requirements and performance goals

Benefits

• Ability to travel up to 30% of the time, both domestically and internationally
• Extended working hours and occasional weekends to support production ramps and critical issue resolution
• This position is based in Bastrop, TX and requires being onsite
• U.S. citizen or national, U.S. lawful, permanent resident (aka green card holder), Refugee under 8 U.S.C. § 1157, or Asylee under 8 U.S.C. § 1158, or be eligible to obtain the required authorizations from the U.S. Department of State.
