Job brief

We are looking for a dedicated Marine Engineer to join our technical operations team and ensure the high-performance maintenance of our diverse maritime fleet. In this role, you will take ownership of engine room systems, spearhead preventative maintenance programs, and lead technical troubleshooting efforts during critical sea transits. You will work closely with port engineers, deck officers, and third-party contractors to modernize our mechanical infrastructure and improve fleet energy efficiency. If you are a hands-on problem solver with a passion for maritime technology and safety, we invite you to advance your career with our dynamic organization.

Key highlights

Design and optimize ship propulsion systems, power generation units, and auxiliary machinery to enhance fuel economy and overall vessel reliability.
Monitor real-time system performance using SCADA and PLC interfaces to detect operational anomalies before they escalate into costly failures.
Oversee dry-docking operations, including hull inspections, shaft alignment, and propeller maintenance, while managing vendor-provided repair services.
Ensure all shipboard engineering activities strictly comply with SOLAS, MARPOL, and flag state requirements to maintain operational licensing.

What is a Marine Engineer?

A Marine Engineer is a specialized professional responsible for the design, construction, operation, and maintenance of propulsion systems, power plants, and auxiliary machinery aboard ships and offshore structures. Marine Engineers apply rigorous mechanical and electrical engineering principles to ensure vessels remain seaworthy, fuel-efficient, and compliant with international maritime regulations like IMO and MARPOL. Their expertise is foundational to the safety, reliability, and operational continuity of global shipping, offshore oil and gas, and naval defense fleets.

What does a Marine Engineer do?

A Marine Engineer oversees the daily performance of shipboard mechanical systems, including diesel engines, turbines, steam generators, and hydraulic pump assemblies. They conduct diagnostic analysis using vibration monitoring, thermal imaging, and oil analysis to prevent equipment failure before it disrupts maritime operations. These professionals collaborate with naval architects, port authorities, and regulatory bodies to perform dry-dock repairs, conduct sea trials, and manage complex engineering refits that maintain vessel integrity and adherence to international safety protocols.

Key responsibilities

Design and optimize ship propulsion systems, power generation units, and auxiliary machinery to enhance fuel economy and overall vessel reliability.
Execute comprehensive preventative maintenance schedules for marine engines, boilers, and electrical switchboards based on OEM technical guidelines.
Monitor real-time system performance using SCADA and PLC interfaces to detect operational anomalies before they escalate into costly failures.
Perform detailed forensic analysis on failed mechanical components to identify root causes and implement sustainable engineering modifications.
Oversee dry-docking operations, including hull inspections, shaft alignment, and propeller maintenance, while managing vendor-provided repair services.
Ensure all shipboard engineering activities strictly comply with SOLAS, MARPOL, and flag state requirements to maintain operational licensing.
Prepare precise technical documentation, including maintenance logs, performance reports, and repair budgets for review by shore-side management teams.
Coordinate with naval architects and electrical engineers to integrate new automation technologies or emission-reduction systems into existing vessels.

Requirements and skills

Bachelor’s degree in Marine Engineering, Naval Architecture, or a closely related Mechanical Engineering discipline.
Possession of a valid STCW-compliant Certificate of Competency (CoC) as a Marine Engineer Officer (Class 1 or 2).
Proven proficiency in using AutoCAD and SolidWorks for reviewing technical schematics and designing mechanical system modifications.
Deep technical knowledge of high-speed diesel engine maintenance, centrifugal pumps, and complex hydraulic control systems.
Strong familiarity with maritime regulatory standards, including ISM Code, STCW, and Class Society rules like ABS or DNV.
Hands-on experience with shipboard automation systems, programmable logic controllers (PLCs), and electronic governor controls.
Ability to communicate complex technical risk assessment data clearly to ship captains, crew members, and offshore stakeholders.
Demonstrated expertise in managing multi-stage technical projects, from initial design feasibility to final sea-trial validation.

FAQs

What does a Marine Engineer do on a daily basis?

A Marine Engineer manages the mechanical integrity of a vessel, which involves performing scheduled maintenance on main propulsion engines and auxiliary equipment like compressors and purifiers. On a daily basis, they troubleshoot electrical faults using diagnostic tools, monitor fluid levels and pressures via SCADA systems, and ensure that the engine room logbooks are accurate and compliant with international maritime law. They also spend significant time planning for upcoming port calls and managing spare parts inventory to ensure the vessel remains operational at sea.

What are the essential qualifications for a Marine Engineer?

To become a professional Marine Engineer, you typically need a Bachelor's degree in Marine Engineering or a related technical field, often combined with specialized training at a maritime academy. Most roles require a valid Certificate of Competency (CoC) issued under STCW standards, which proves your ability to safely manage shipboard power plants. Practical experience with engine room machinery, safety certifications like BOSIET, and proficiency in CAD software are often highly valued by employers in the shipping and offshore industries.

Who does a Marine Engineer work with in the maritime industry?

A Marine Engineer works in a cross-functional environment, collaborating closely with the Captain and deck officers to coordinate engine performance with vessel navigation requirements. They interact frequently with shore-side technical superintendents, port authorities, and regulatory inspectors from Class Societies to certify equipment safety. Additionally, they supervise engine room ratings and technicians and coordinate with external vendors and specialized contractors during major dry-docking or vessel refit projects.

Why is the role of a Marine Engineer important for shipping companies?

The role of a Marine Engineer is vital because they are directly responsible for the availability and safety of a vessel’s mechanical heart. By optimizing fuel consumption, conducting proactive repairs, and ensuring strict adherence to environmental regulations like MARPOL, they minimize downtime and protect the company from significant financial losses and legal penalties. Their technical oversight ensures that shipping operations remain efficient, safe for the crew, and sustainable within the highly regulated global maritime transport sector.
