We’re looking for early‑career Mechanical Engineers with a passion for solving complex engineering problems to join our growing team. Whether you already have experience in pressure systems design or are eager to develop these skills, this role offers the opportunity to contribute to critical energy‑sector projects while growing your technical capability. As a Mechanical Engineer, you’ll play an important role across our Power and Energy Solutions business as we drive towards new energy solutions.

As well as delivering what’s best for major organisations, you’ll be able to point to something that improves thousands of lives every day and say, “I helped make this happen.” You’ll work on a broad range of projects with plenty of opportunities to deepen your technical expertise and keep yourself challenged.

Your role

You will support and deliver design projects that provide piping and process‑plant solutions for the next generation of energy infrastructure in the UK and internationally. You will also play a key role in the energy transition by supporting the operation, maintenance and enhancement of existing energy assets across a diverse range of clients and technologies.

Your work may involve integrity assessments of existing equipment, design substantiation for system modifications, supporting client outage/turnaround activities, or contributing to low‑carbon and future‑energy projects. This variety gives you the chance to develop a strong foundation in mechanical integrity, pressure systems and plant engineering.

• Producing clear, accurate and concise technical documentation (e.g., design calculations, substantiations, basis‑of‑analysis reports).
• Working with clients—remotely or at their sites—to understand their issues, goals and processes.
• Contributing to analyses of piping systems, pressure vessels or associated mechanical equipment.
• Supporting senior engineers in delivering engineering solutions across conceptual, FEED, detailed design and operational support scopes.

About you

• Degree‑qualified Mechanical Engineer (or relevant equivalent).
• Good experience in mechanical, plant, utilities or energy‑sector roles.
• Ability to apply sound engineering judgement and fundamental mechanical principles.
• Strong written communication skills, particularly in technical reporting.
• Experience in piping and/or pressure‑vessel design and stress analysis.
• Understanding of design codes such as ASME/BPVC Section VIII, BS EN 13445, PD 5500, ASME B31.1, ASME B31.3 or BS EN 13480.
• Awareness of UK legislation relating to pressure systems.
• Experience in pressure‑equipment design, fabrication, operation, maintenance or asset life‑management.
• Experience or interest in fitness‑for‑service assessments including API 579 or BS 7910.
• Progress toward chartership with a relevant professional institute.
• Experience in the energy or utilities sectors, particularly in plant operations, maintenance or reliability.
• Experience in pressure‑parts design or fitness‑for‑service as listed above is beneficial but not essential—we welcome applicants who are motivated to develop these skills with our support.
