· 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
