About The Position

Fathom Robotics provides operations, maintenance, training, and applied engineering services for uncrewed maritime systems supporting U.S. Government and commercial defense programs. We have multiple active projects across a variety of government and commercial clients and are actively fielding systems in operational environments. Fathom Robotics is hiring a Mechanical Engineer to design and build payloads for uncrewed surface and underwater vehicles. You will take payload hardware from a customer requirement through CAD, prototype, fit-check, and test, then support it on the water. We are looking for an experienced engineer who has put real prototypes in the field and can move a design from sketch to working hardware without a large support structure. The hardware you build goes onto vehicles supporting active government and commercial defense programs.

5+ years of mechanical design experience, with a record of prototypes taken from concept to working hardware
Strong CAD skills in Onshape or SolidWorks, including fabrication drawings and GD&T
Hands-on fabrication: machining, 3D printing, sheet metal, or composites
Design for manufacture and experience working with machine shops and fabrication vendors
Experience designing for harsh or wet environments, including O-ring and seal design
Comfortable working in a shop, outdoors, and on boats
US Person status required (defense program context)
Must be able to pass a background check and be eligible to obtain a SECRET clearance

Responsibilities

Design payload hardware for USVs and AUVs, including enclosures, pressure housings, mounts, brackets, fairings, and structural interfaces
Take designs from concept through prototype, fit-check, and revision on a fast turn
Fabricate prototype parts in-house and manage outside machine shop and vendor builds
Produce fabrication drawings with GD&T and keep design revisions under control
Design for the marine environment: sealing, corrosion, material selection, shock, vibration, and depth rating
Work with platform OEMs, payload vendors, and government customers to define mechanical and electrical interfaces and SWaP limits
Coordinate cable, connector, and harness routing with the electrical team
Plan and run bench, leak, pressure, and vibration tests before hardware goes to the field
Support payload integration and on-water testing, including launch and recovery
Document designs, test results, and field findings
