Fluid System Development Engineer

Job description

We’re seeking a Fluid System Development Engineer to support the design, development, and test of fluid systems that enable vehicle operation and reliability (fuel, cooling, hydraulics/pneumatics, lubrication, seawater handling, and related controls—depending on platform needs). You’ll help take systems from concept through requirements, layout, prototyping, and qualification—aligned with how space and aerospace teams develop flight-critical fluid systems (pumps, valves, actuators, controls).

Job responsibilities

  • Support architecture and detailed design of fluid systems: schematics (P&IDs), component selection, routing/layout, mounting, and serviceability.
  • Size components and lines using first principles and simple models (pressure drop, flow rates, heat transfer) and validate assumptions with test.
  • Partner with mechanical/electrical/software teams on sensors, controls, and fault detection for fluid subsystems.
  • Create and execute development tests: leak checks, performance characterization, endurance screening, and instrumentation plans.
  • Own tight feedback loops: capture issues, propose design changes, and re-test quickly with strong documentation.
  • Support producibility: BOM rationalization, supplier engagement, assembly procedures, and verification checklists.

Job requirements

  • BS in Mechanical, Aerospace, or related engineering discipline.
  • Comfortable working with physical hardware and learning hands-on (fittings, tubing, seals, pumps/valves, instrumentation).
  • Strong fundamentals in fluids/thermo and an engineering mindset that balances performance, safety, and maintainability.
  • Clear, collaborative communicator who can translate field observations into actionable design improvements.
