Marine Engineer; PT

Overview

Vessel/Platform: LCM-8 Mod 1 (twin-screw ~75 ft landing craft) used as our testing platform for ongoing operations and development work for our hull cleaning device. Future Opportunity:
Strong performers may transition to a full-time role at the company as needs grow. We are seeking a hands-on marine engineer to support the maintenance, reliability, and occasional assistance with operation of our LCM-8 testing platform. This role focuses on preventative maintenance, troubleshooting, and repair execution across diesel propulsion, electrical, hydraulics, plumbing, bilge/dewatering, and general marine systems. The ideal candidate can operate the engineering side similarly to a licensed marine engineer and can reasonably man the helm when needed for a twin-screw ~75 ft vessel (USCG 100-Ton Master Captain's License Desired, But Not Required
).

• Maintenance & readiness:
  Execute preventative maintenance for main propulsion diesels (Detroit Diesel familiarity preferred), gears, and auxiliary systems
• Maintain fuel, lube oil, cooling, and raw-water systems; monitor/resolve leaks, overheating, and contamination issues
• Maintain and troubleshoot hydraulic systems (pumps, valves, filtration, hoses/fittings, HPUs) and hydraulic deck machinery as installed
• Maintain electrical systems (DC distribution, starting/charging, batteries, alternators; shore power/AC panels/generators as installed)
• Maintain plumbing systems (freshwater/raw water, heads/sanitation, washdowns) and general marine plumbing systems
• Maintain bilge/dewatering systems, alarms, and emergency systems (and fire systems as installed)
• Maintain a clean, orderly engine room and service spaces; keep tools/spares organized and inspection-ready
• Maintain vessel in compliance with modern USCG rules and regulations
• Operational engineering support:
  Perform pre-sail checks and post-run inspections; track consumables (fuel/transmission & engine oil/coolant) and operating hours
• Stand engineering watch as needed and support safe operations (LOTO discipline, spill prevention, dewatering readiness)
• Document defects and corrective actions; coordinate vendors, services, and parts procurement
• Recommend practical reliability improvements and upgrades (no unnecessary complexity)
• Develop SOPs and documents for startup, running, and troubleshooting procedures for all systems
• Helm support:
  Serve as a relief helm on a twin-screw vessel when required, including docking/undocking support and close-quarters maneuvering
• Coordinate effectively with crew for line handling and safe vessel movements

• 5+ years of hands-on marine engineering, marine diesel, port engineer, or commercial vessel experience
• Maintenance Experience with strong mechanical troubleshooting skills (diesel propulsion and auxiliaries)
• Working knowledge of marine electrical (DC/AC), including safe use of meters and basic schematic comprehension
• Working knowledge of marine hydraulics (pressure/flow troubleshooting, contamination control, hose/fitting standards)
• Comfortable working in engine rooms (heat/noise/confined spaces, ladders, lifting, dirty work)
• Ability to write clear maintenance notes and communicate issues directly and professionally

• Detroit Diesel 71-series familiarity (e.g., 6-71 / 12V-71), including cooling system discipline and injector-related troubleshooting
• Twin-screw handling experience on workboats/landing craft/tugs
• Generator troubleshooting, shore power integration, battery bank management
• Familiarity with USCG/inspection credentials/credentials requirements

• Strong safety habits are required; credentials/qualifications preferred: USCG Merchant Mariner Credential (MMC) with an engine-room rating QMED (Qualified Member of the Engine Department) or higher, and Designated Duty (DDE) endorsement; TWIC;
