Job summary

Greywright is seeking a Mechanical Engineer to design and improve structures, mounts, and enclosures for equipment aboard small autonomous vessels. You will create robust systems that survive slamming, vibration, and saltwater, validating with FEA and testing.

You’ll work with senior mechanical engineer, naval architect, and electrical team, owning designs through build and sea trials, with opportunities to travel up to 50% and contribute to hands-on fabrication and testing.

Qualifications

• B.S. in Mechanical, Marine, or Ocean Engineering.
• 5+ years of mechanical design experience on small vessels.
• Hands-on FEA experience for structural, shock, and vibration problems (e.g., ANSYS, Abaqus, or SolidWorks Simulation).
• Understanding of loads small craft experience at sea, including slamming and wave impact.
• Proficiency with 3D CAD (e.g., SolidWorks, NX, or Creo) and GD&T.
• Knowledge of marine materials and corrosion, including stainless steels, aluminum, and composites.
• Hands-on attitude and comfort working on boats and in the shop.
• Willingness to travel up to 50% of the time when needed.
• This role requires access to ITAR/EAR-controlled data; U.S. person status is required as defined by 22 CFR 120.62.

Responsibilities

• Design mechanical systems for carriage on small vessels, including equipment mounts, foundations, racks, enclosures, and payload integration.
• Perform FEA for structural, shock, vibration, and slamming loads, and use the results to size and refine designs.
• Design for the marine environment: corrosion resistance, sealing and waterproofing, and material selection.
• Develop isolation and mounting approaches that protect sensitive electronics from shock and vibration.
• Create 3D CAD models, drawings, and tolerance stack-ups, and release designs for fabrication.
• Work with machine shops, fabricators, and suppliers to build and install parts.
• Support environmental testing and sea trials, and correlate test data with analysis.
• Document designs, analyses, and test results.
