Mechanical Engineer - Nuclear

Job Description

Are you a Mechanical Engineer, with a background in either mechanical analysis or design, who thrives on difficult problems? Are you drawn to complex projects and excited by the opportunity to rapidly move on to leadership positions, heading up projects and guiding junior engineers?

If so, you might enjoy solving the energy industry’s most important conundrums across a variety of clients. You could be designing test rigs in support of the development of the UKs nuclear fusion capabilities, carrying out structural integrity assessment of primary plant to keep existing fleet generating, supporting the UK Submarine and SMR programmes, or enabling one of many renewable energy projects across a growing carbon net zero portfolio. You’re likely to be juggling several projects simultaneously, so enjoying being adaptable is a must! The constant in this role is the complex nature of the jobs and the chance to provide innovative solutions to a range of problems for several appreciative clients.

Whichever energy-related projects you get involved in, you’ll be engaged in developing engineering solutions to the industry’s most challenging problems, making a significant contribution to the energy and environmental security of the UK and beyond.

If you are a self-starter who can deliver multiple projects at the same time, working closely with clients and internal teams to capture requirements, set up projects, and deliver right-first-time solutions, then we’d love you to apply.

Role Requirements

You will work within small to medium-sized teams. To benefit from the collective experience of the team and our clients, and to drive innovative thinking, you’ll work in a collaborative and supportive office/site environment for at least half of your working week. You will bring a level of commercial awareness to effectively deliver tasks across multiple workstreams, ensuring delivery on time, within scope, and within budget.

Essential Criteria

• Degree qualified mechanical engineer (or other relevant qualification).
• Experience in mechanical engineering substantiation for new designs or existing plant.
• Experience in writing accurate, detailed, and concise technical reports (e.g., design substantiations, basis of analysis, safety case references).
• Experience in delivering mechanical engineering solutions with accountability.
• Ability to engage with existing and prospective clients, working at their sites and understanding their issues, goals, and processes.

Additional Experience (Desirable but not mandatory)

• Experience in Finite Element Analysis, e.g., using ABAQUS.
• Experience in piping and pressure vessel design and stress analysis.
• Experience in bidding within safety-critical and heavily regulated environments.
• Knowledge of design codes such as ASME BPVC Section III, RCC-M, ASME B31.1, BS EN 13480, and BS EN 13445.
• Experience in automation tools, e.g., using PYTHON.
• Chartered status or approaching registration with a relevant professional institute.
