Role SummaryWe're seeking a Senior Power Systems Mechanical Engineer to support development of next generation power plants for naval applications. The development of autonomous ships demands a step change in the reliability of ship power systems. Here at Blue Water we are working on architecting power generation and transmission systems that can survive for months untouched in a harsh maritime environment. In this role you would be responsible for system and component design, test, and validation to enable modular power generation for a range of applications from 1-50MW. This Role is highly interdisciplinary and will need to work closely with the ship design team and power electronic design team.
What You'll Do- Support architecture and detailed design of fluid, mechanical and electrical systems: schematics (P&IDs), component selection, routing/layout, mounting, and serviceability.
- Partner with mechanical/electrical/software teams on sensors, controls, and fault detection for fluid subsystems.
- Utilize the FMECA/FMEA process to ensure the ship systems are robust to individual failures and capable of graceful degradation
- Create and execute development development, acceptance and qualification test plans to verify the feasibility, capability and build quality of your designs
- Create and maintain 3D CAD of mechanical assemblies
- 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.
- Working with and managing vendors to ensure on time delivery of critical hardware.
Who You Are- Clear track record of delivering novel hardware for complex integrated systems.
- An extreme owner who wants to develop a product from cradle to grave and understand every aspect of how it operates.
- Someone who is able to think at the vehicle level about how their engineering decisions impact the broader system.
- Someone who challenges requirements and ensures you are working towards the correct requirements and goals.
- Comfortable working with physical hardware and learning hands-on (fittings, tubing, seals, harnessing, pumps/valves, instrumentation).
- Strong fundamentals in fluids, thermal, mechanical and electrical design and an engineering mindset that balances performance, safety, and maintainability.
- Clear, collaborative communicator who can translate field observations into actionable design improvements.
- BS in Mechanical, Aerospace, or related engineering discipline.
Nice to Haves- Familiarity with high voltage/high power electronics and safety practices.
- Strong familiarity with ASME Y14.5 and corresponding drafting requirements
- Experience with qualifying mil-spec hardware for marine, aviation or space applications.
- 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).
What We Offer - Incredibly high-caliber teammates. You'll work directly with our co-founders.
- A fast-paced, creative working environment that offers a lot of room for ownership and growth.
- Opportunity to join a meaningful mission that protects American and our Democracy.
- Salary Range: $110,000 - $130,000 annual base salary (final compensation will depend on experience and skill level
- Startup equity options
- Generous PTO, medical, dental, and vision coverage.
