Job Description

Are you a Mechanical Design Engineer who thrives on solving difficult engineering problems? Are you drawn to complex projects and eager to develop your technical leadership by heading multi-disciplinary projects?

If so, you might enjoy tackling the energy industry’s most critical mechanical engineering challenges across various energy systems for diverse clients. Your work could include designing test rigs for UK nuclear fusion development, assessing structural integrity of primary plant in civil and defense applications, creating high-integrity structures for new nuclear facilities, or leading renewable energy projects within a growing carbon net-zero portfolio. Managing multiple projects simultaneously requires adaptability, and the role offers the chance to provide innovative solutions to complex problems, making a significant contribution to UK and global energy security.

If you are a self-starter capable of managing multiple projects, collaborating closely with clients and internal teams to understand requirements, initiate projects, and deliver precise solutions, we encourage you to apply.

• Experience supervising optioneering studies for design solutions.
• Experience reviewing mechanical substantiation for new or existing designs.
• Proficiency in writing, reviewing, and approving technical reports (design calculations, safety cases, etc.).
• Ability to liaise confidently with stakeholders at all levels, internally and externally.
• Proven leadership in successful engineering projects with varying team sizes.
• Accountability in delivering mechanical engineering solutions.

Please indicate if you have experience in any of the following (but apply even if you're eager to gain this experience):
