## Description

We are seeking a talented and motivated Mechanical Build Engineer to support the design, integration, and commissioning of main propulsion systems and associated machinery for autonomous surface vessels. This role will provide hands-on experience in marine propulsion machinery, shafting systems, fuel systems, generator sets, seawater systems, and advanced autonomous technologies, driving impact in defense innovation. As a Mechanical Build Engineer, you'll interface remotely with our design engineering teams in Austin while owning the hands-on oversight of main engine installation, shaft alignment, propulsion integration, fuel systems, gensets, cooling systems, and issue resolution at the shipyard., * Assist in the design, analysis, and integration of main propulsion systems, fuel systems, seawater cooling systems, and generator sets including main engines, transmissions, shafting, propellers, waterjets, steering systems, fuel supply/return, day tanks, genset packages, seawater intakes, heat exchangers, and exhaust systems

 * Collaborate with engineering teams to perform CAD modeling, analysis, and system optimization
 * Operate as liaison between engineering, drafting, and production teams to resolve technical challenges during construction
 * Identify and resolve non-conformances, lead root cause analysis, and drive resolution via IRBs (Issue Review Boards) and rework plans
 * Lead and coordinate Engineering Change Orders (ECOs)-ensure traceability, communication, implementation, and verification
 * Support the integration of autonomous navigation and control systems into vessel designs
 * Participate in design reviews and provide technical input on system architecture and performance
 * Support documentation including technical drawings, specifications, test procedures, and as-built records for internal use, regulatory bodies, and client presentations
 * Manage CAD models to document as-built changes made during ship construction
 * Oversee installation, alignment, and commissioning of main engines, shafting systems, stern tubes, propellers, rudders, steering gear, and generator sets
