Mechanical Build Engineer

Saronic Technologies is a leader in revolutionizing autonomy at sea, dedicated to developing state-of-the-art solutions that enhance maritime operations through autonomous and intelligent platforms.

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
• Lead precision shaft alignment procedures using laser alignment equipment and ensure compliance with manufacturer and classification society tolerances
• Perform functional testing and commissioning including engine run-ups, genset load testing, fuel system pressure tests, cooling system verification, and alignment checks

• Bachelor's degree in Marine Engineering, Mechanical Engineering, Naval Architecture, Ocean Engineering, or a related field
• Familiarity with maritime industry standards including ABS machinery rules, ABYC fuel system standards, engine manufacturer specifications, and US Coast Guard engineering regulations
• Strong fundamentals in mechanical engineering principles including propulsion systems, shaft alignment, fuel systems, cooling systems, generator sets, and marine machinery
• Experience working in a shipyard, aboard ships, or with marine propulsion systems, fuel systems, gensets, and seawater cooling systems
• Strong knowledge of 2D and 3D CAD software (e.g., Solid Works, AutoCAD, Rhino, NX)
• Experience with shaft alignment procedures, laser alignment equipment, and propulsion system installation
• Deep familiarity with interpreting P&IDs, machinery arrangement plans, fuel system diagrams, cooling system schematics, and shaft alignment specifications
• Understanding of diesel and alternative propulsion systems, fuel delivery and filtration, seawater cooling systems, heat exchangers, and exhaust systems
• Knowle…
