Fluid Systems Engineer, Solar Cell Factory (Starlink)

Fluid Systems Engineer, Solar Cell Factory (Starlink) Bastrop, TX 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 ofenabling human life on Mars. The Solar Cell team is revolutionizing power generation for space applications through advanced solar cell manufacturing. We're scaling production of high-efficiency solar cells to support sustainable energy solutions for Starlink constellations, launch vehicles, and beyond. As a Solar Cell Factory Fluids Engineer, you will design, build, and optimize fluid systems for the delivery of critical gases and chemicals in solar cell fabrication. This role requires a detail-oriented engineer passionate about safe handling of hazardous materials in a high-volume manufacturing environment, ensuring reliable supply to processes like vacuum deposition and etching while minimizing risks and maximizing efficiency in our cutting-edge solar cell factory.

RESPONSIBILITIES:

Design, build, and activate fluids systems for the distribution of key gases (e.g. specialty and bulk gases), chemicals (e.g., hydrofluoric acid, solvents) and exhaust systems used in solar cell processes, including tanks, pumps, heat exchangers, gas panels, valves, scrubbers, and abatement systems Cradle-to-grave project ownership including requirement definition, design, justification of key decisions, equipment procurement, build coordination, commissioning and project management throughout Design modular systems capable of being manufactured at scale for future solar production facilities Apply fluids/mechanical engineering skills such as P&ID development, equipment sizing, detailed fluid and thermal analysis, system-level CONOP development, structural analysis, materials and component selection. Perform safety/hazard assessments (ex. FMEAs, HAZOPs) to ensure appropriate hazardous system design, including emergency shutdown CONOPs, redundancy, and general compliance with hazardous material safety standards Design, build, and deploy data acquisition and control systems for fluid facilities control and monitoring Collaborate with process engineers to integrate fluid systems with manufacturing equipment and optimize delivery rates, purity levels, and recovery/recycling of process fluids to support high-yield production Support installation, commissioning and troubleshooting of fluid systems, working closely with facilities operations, EHS, automation, and procurement teams to resolve issues and implement improvements Ensure regulatory compliance with OSHA, EPA, ASME, NFPA, and SEMI standards for chemical and gas handling in semiconductor-like environments Track system performance metrics (e.g., flow rates, contamination levels, downtime) and contribute to continuous improvement initiatives, such as lean manufacturing and sustainability efforts for fluid reuse

BASIC QUALIFICATIONS:

Bachelor’s degree in mechanical engineering, chemical engineering, aerospace engineering, or other engineering discipline 1+ years of hands- on build or design experience (internship, club, and competition team experience qualifies)

PREFERRED SKILLS AND EXPERIENCE:

Advanced degree in engineering or related field 2+ years of experience in fluid systems design, particularly with gases or hazardous chemicals in manufacturing or semiconductor industries 2+ years of experience in photovoltaic, semiconductor, or thin-film deposition manufacturing Knowledge of safety protocols for handling pyrophoric materials (e.g., silane) and toxic gases/chemicals (e.g., phosphine, HF) Knowledge of ASME B31.3, SEMI S2/S8 standards and experience with cleanroom HVAC integration for fluid systems Familiarity with cleanroom fluid systems, gas cabinets, scrubbers, and wastewater neutralization for solar cell fabrication Familiarity with air separation units (ASUs) for gaseous nitrogen production. Certification in process safety (e.g., CSP, Six Sigma Green Belt) or hazardous materials handling Proficiency in fluid dynamics software (e.g., ANSYS Fluent, Pipe-Flo) and CAD tools (e.g., AutoCAD, SolidWorks) for system modeling and diagramming Experience with process safety management, including risk assessment and regulatory compliance Ability to thrive in a fast-paced, iterative environment and collaborate across multidisciplinary teams Ability to work independently, take initiative, and communicate effectively Ability to rapidly change roles/responsibilities while maintaining a high sense of urgency in a demanding work environment Creativity to imagine and design for reliability, efficiency, and maintainability from scratch

Voluntary Self-Identification For government reporting purposes, we ask candidates to respond to the below self-identification survey. Completion of the form is entirely voluntary. Whatever your decision, it will not be considered in the hiring process or thereafter. Any information that you do provide will be recorded and maintained in a confidential file. A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability. A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service. An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense. An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985. Voluntary Self-Identification of Disability Form CC-305 Page 1 of 1 OMB Control Number 1250-0005 Expires 04/30/2026 Why are you being asked to complete this form? We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.
