• Support technical interfaces with classification societies, including technical submissions and resolution of electrical comments where required.
• Provide technical support during tendering, including scope definition, equipment selection, engineering estimates, technical risk assessment and technical clarifications.
• Mentor junior electrical engineers and technicians as the engineering team develops.

VFD Expertise – Essential

The successful candidate must demonstrate significant hands-on engineering experience with Variable Frequency Drive systems, covering both system design and practical application, ideally from major manufacturers such as ABB, Siemens, Danfoss, Schneider Electric, Rockwell, or equivalent.

Experience should include:

• VFD sizing and selection
• LV drive systems, with experience or strong technical understanding of MV drive systems
• VFD/motor matching
• Induction and permanent-magnet motors
• Constant and variable torque applications
• Pump, fan, compressor, winch and other motor-driven machinery applications
• Drive parameterisation and commissioning
• Harmonics and harmonic mitigation

• Protection and interlocking
• Understanding of drive safety functions, including Safe Torque Off (STO), and associated machinery safety interfaces
• PLC/VFD integration and industrial communications, including Profinet, Profibus, Modbus RTU/TCP, EtherNet/IP or equivalent protocols
• Fault diagnosis and troubleshooting
• FAT, SAT and commissioning of drive systems
• Knowledge of applicable VFD standards, particularly the IEC 61800 series

Experience with modern LV and MV VFD platforms from manufacturers such as ABB, Siemens, Danfoss, Schneider Electric, Rockwell or equivalent would be particularly valuable.

Marine / Offshore Experience – Essential

Candidates should have previous experience within one or more of the following:

• Commercial vessels, offshore vessels, FPSOs / offshore production facilities, drilling rigs, shipyards
• Marine electrical system integrators, marine electrification, marine electrical retrofit projects
• Offshore equipment manufacturers, offshore process/package equipment, propulsion or thruster systems

Essential:

• Degree/HND or equivalent qualification in Electrical Engineering
• Typically 8+ years' electrical engineering experience
• Strong marine/offshore electrical engineering background
• Demonstrable specialist experience with VFD systems
• Strong understanding of LV electrical distribution and associated protection systems
• Experience with motors, MCCs and switchboards and electrical drive systems
• Ability to read and develop electrical single-line diagrams and schematics
• Experience with electrical calculations, power system studies, protection coordination and equipment selection
• FAT, SAT and commissioning experience
• Strong fault-finding and troubleshooting capability
• Experience working directly with OEMs, suppliers and customers
• Ability to interpret and apply relevant electrical standards, marine classification requirements and manufacturer documentation
• Good written and spoken English.

Highly desirable:

• Experience with MV electrical systems, including MV distribution, switchgear, protection, transformers and associated cable systems
• Experience with MV VFD / drive systems
• Marine propulsion and thruster drives
• Compressor, pump, fan, winch and other motor-driven machinery packages

• Flexible work schedule and hybrid work options.
• Modern work equipment (laptop, company phone).
• Access to international projects and complex collaborations.
• Opportunities for professional training and specialization.
• Annual bonuses and rewards for outstanding performance.

We are looking for someone practical as well as technically strong. This is not intended to be a purely office-based design role.

The successful candidate should be comfortable moving between engineering, onboard surveys, workshop integration, FAT, SAT, and vessel/site commissioning, and should be capable of taking ownership of electrical problems and driving them through to resolution.

They should be commercially aware, comfortable dealing directly with customers, OEMs, and suppliers, and capable of serving as the senior electrical authority on multidisciplinary projects.

The Senior Electrical Engineer will help GLO Marine build a strong internal capability in marine electrification, drive systems, power systems engineering, and electrical integration, reducing reliance on external engineering support and enabling the company to take greater ownership of technically complex electrical and packaged-system projects.

They will play a key role in developing the electrical engineering capability required to support GLO Marine's expanding work in marine electrification, VFD-driven equipment, e-houses, process packages, compression systems,  shore power, BESS/hybrid systems, and OEM integration projects.
