Job summary

Greywright Inc is hiring a Senior Mechanical Engineer to lead the build-out and improvement of propulsion and mechanical systems for high-performance autonomous vessels. You will own the diesel engines, drivetrains, and supporting systems from selection through testing and fielding.

In this role you will ensure long-endurance operation without crew, integrate engines with autonomy systems, and mentor junior engineers while driving design standards and reliability.

Qualifications

• A B.S. in Mechanical, Marine, or Ocean Engineering or related field is required.
• Experience of 10+ years in mechanical engineering with marine propulsion systems is required.
• Deep experience with marine diesel engines: selection, installation, integration, and troubleshooting.
• Strong knowledge of drivetrains and propulsors (gearboxes, shafting, propellers, waterjets) is required.
• Experience designing engine support systems (fuel, cooling, exhaust, mounting) is required.
• Experience with engine electronic controls and monitoring (e.g., J1939, NMEA 2000) is required.
• Proficiency with 3D CAD and engineering analysis is required.
• Track record of supporting dockside and sea trials and solving field problems is required.
• Willingness to travel up to 50% of the time when needed.

Responsibilities

• Lead integration and improvement of marine propulsion systems on baseline platforms, and selection for new variants, including diesel engines, gearboxes, shafting, propellers, and waterjets.
• Size and match engines and propulsors to hull performance, mission profiles, and speed and endurance targets.
• Design supporting systems: fuel, cooling, exhaust, air intake, lubrication, and engine mounting.
• Integrate engines with electronic control, monitoring, and autonomy systems for uncrewed operation, including remote start, throttle and shift control, and health monitoring.
• Design for reliability, maintainability, and long-endurance operation without onboard crew.
• Lead shock, vibration, and noise analysis of the propulsion train, and work with naval architecture on weight, center of gravity, and signature.
• Work with engine and drivetrain OEMs and suppliers on specifications, integration, and support.
• Plan and lead propulsion testing, from dyno and dockside trials through sea trials, and drive design changes from the data.
• Mentor other mechanical engineers and set design standards for the team.
