If you are passionate about mechanical engineering, and want to play a pivotal role in delivering engineering excellence for regulated industry projects, we’d love to hear from you.

Mechanical Design Engineering – Designer, Engineer, Senior Engineer, Principal Engineer

Join our expert Mechanical Design Engineering team and work at the forefront of engineering innovation for the UK’s industrial and energy sectors, including nuclear, process, and heavy industry. Our projects span concept to detail design, giving you the chance to own and deliver work that shapes the future. We offer rewarding opportunities for people with experience in mechanical systems, equipment, and plant layout—at every career stage.

Main Responsibilities

Lead or contribute to the development of high-quality mechanical design deliverables, such as equipment layout drawings, detailed component designs, 3D CAD models, calculations, and technical reports.
Collaborate closely with multi-disciplinary teams (EC&I, process, and project management) to ensure fully integrated engineering solutions.
Apply knowledge of mechanical systems and industry standards to engineer safe, robust, and cost-effective solutions.
Undertake engineering calculations and design validation activities to verify fitness-for-purpose and statutory compliance.
Participate in design reviews, risk assessments, safety studies, and constructability workshops to drive technical excellence and manage potential risks.
Review and check technical documents, drawings, and calculations—supporting continuous improvement of design quality and compliance processes.
Share knowledge, mentor junior engineers and designers, and contribute to a proactive learning environment.
Support the preparation of technical specifications, project documentation, procurement packages, and client proposals.

Proven background in mechanical design ideally within regulated sectors — for example, nuclear, energy, oil & gas, process or heavy industry.
Strong understanding of mechanical engineering principles, mechanical systems and assemblies, and plant/equipment design.
Experience producing or checking 2D drawings and 3D models using CAD software (e.g. AutoCAD, Inventor, or similar).
Knowledge of UK and international engineering standards and statutory regulations.
Ability to communicate effectively—explaining concepts clearly and engaging with diverse teams and clients.
Analytical and detail-focused, with problem-solving skills and a drive for continuous improvement.
Full UK driving licence or ability to travel to client/project sites as needed.

What We Offer

Competitive salary, generous pension contributions, annual bonus, and Health Shield healthcare plan.
Excellent benefits package, including 26 days holiday (plus bank holidays), EV car scheme, company share scheme (qualifying periods apply), and death in service insurance.
Hybrid and flexible working arrangements to support your work-life balance.
A structured pathway for career development and progression—mentoring, technical training, and support from a world-class engineering leader (VINCI Energies).
Inclusive and supportive team environment where every contribution is valued—and innovation and technical achievement are championed.
