Company

Building orbital infrastructure using satellites in Low Earth Orbit to generate and distribute energy and transmit high-bandwidth optical data.

What you will do

• Design valves, regulators, tanks, pressure vessels, accumulators, tubing, manifolds, fittings, flex lines, and quick-disconnects for propulsion, pressurant, and thermal fluid systems.
• Own fluid subsystem layout, integration, and interfaces across propulsion, thermal, pneumatic, and ground systems.
• Perform hydraulic, pneumatic, thermal-fluid, and structural analyses, including pressure drop, flow distribution, water hammer, thermal transients, and pressure-vessel calculations.
• Create detailed component and assembly drawings, specifications, and interface control documents.
• Support component and system-level proof, burst, flow, leak, and cycle-life testing, as well as vehicle integration and fill/drain operations.
• Work with manufacturing and technicians to resolve build issues and improve producibility, reliability, and reuse through anomaly investigation and post-flight inspection.

Requirements

• Bachelor’s degree in Mechanical, Aerospace, Chemical, or a related engineering field.
• 3+ years of experience designing fluid system hardware for flight or high-performance applications.
• Experience with fluid system analysis, pressure vessels, or thermal-fluid modeling.
• Hands-on experience taking hardware from design through build and test.
• Proficiency with NX, CATIA, or SolidWorks for detailed part and assembly design.
• Must satisfy U.S. ITAR eligibility requirements, including U.S. citizenship, lawful permanent residency, protected individual status, or eligibility to obtain the required authorizations.

Nice to have

• Experience with launch vehicle or spacecraft propulsion fluid systems and cryogenic fluid handling.
• Experience designing or qualifying solenoid, pneumatic, or mechanically actuated valves.
• Knowledge of material compatibility with LOX, methane, hydrazine, NTO, helium, and nitrogen.
• Experience with additive manufacturing, advanced fabrication, propulsion hot-fire testing, or vehicle fill/drain operations.
• Familiarity with AIAA, SAE, MIL-spec, and ASME pressure vessel standards.
