About This Role

About our client

Our client is an engineering and manufacturing business serving the marine, fishing, aquaculture, energy and renewables sectors. Established in 2005, it specialises in coded welding and marine fabrication. It also designs and manufactures its own patented marine access equipment for piers and vessels. Its in-house team takes projects from concept through design, prototyping and fabrication, and it provides on-site support in Ireland, the UK and overseas.

The role

This is a permanent, full-time role for a Design Mechanical Engineer in County Donegal. You will join the in-house design team and turn customer requirements into practical, manufacturable designs for marine equipment and fabricated steel structures. You will work closely with the welders and fabricators who build what you design, so your drawings and specifications need to be clear, accurate and workable on the shop floor. Projects range from bespoke one-off solutions to the ongoing development of the company's own products, and you will sometimes work alongside customers, shipyards and naval architects.

What you will do

  • Study each customer's requirements and the conditions the equipment must operate in, and develop concept designs that address them.

  • Produce 3D models, general arrangement drawings and detailed fabrication drawings, including weld details, tolerances and bills of materials.

  • Carry out engineering calculations to confirm that structures and mechanisms are strong, safe and compliant with the relevant standards.

  • Support the prototyping and testing of new designs, then refine them based on the results.

  • Work with the fabrication team to resolve build queries, improve manufacturability and keep projects on schedule.

  • Liaise with customers, shipyards and naval architects to agree technical details and design changes.

  • Prepare and maintain technical documentation, including design records, manuals and quality paperwork.

  • Contribute to the continued development and improvement of the company's own product range.

Key Responsibilities

Essential

  • Experience in a mechanical design engineering role, ideally involving fabricated steel or heavy equipment.

  • Strong skills in 3D CAD and in producing detailed 2D manufacturing drawings.

  • A good understanding of welded fabrication, including weld symbols and how design choices affect build time and cost.

  • The ability to carry out structural and mechanical engineering calculations with confidence.

  • Clear written and spoken English, so you can work with fabricators, customers and outside engineers.

  • The ability to manage several projects at once and keep accurate design records.

Desirable

  • A degree in mechanical engineering or a related discipline.

  • Experience in the marine, offshore, aquaculture or renewables sectors.

  • Knowledge of relevant standards, such as EN 1090 for steel structures or marine classification requirements.

  • Experience with finite element analysis (FEA).

  • A full driving licence, for visits to customer sites.

Benefits

  • Hours: 39 hours a week, Monday to Friday

  • Contract: Permanent, full-time
