Fluid System Development Engineer

We are an early-stage, maritime defense technology startup backed by top tier investors. Our team is designing and building autonomous and highly producible ships that can serve multiple missions on the open ocean.

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).

• →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.

• 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.

• Experience with P&IDs, pressure testing, hydraulic/pneumatic components, or thermal management systems.
• Familiarity with development programs that emphasize reliability, verification, and documentation discipline (common in aerospace/space).
