Principal Mechanical Engineer

Principal Engineer 

If you’re the kind of engineer who thrives on solving complex problems, guiding others, and influencing how projects are delivered, this is the role that puts you in the driving seat. Not just another technical post — this is your chance to lead, shape and elevate engineering standards across meaningful, high‑impact programmes.
You’ll join a team that values expertise, curiosity and clear thinking. A place where experienced engineers step up, take ownership and push for smarter, safer, better ways of working. If you want room to grow, real autonomy and the platform to make a difference, you’ll feel at home here.

What makes this worth your time?

• Lead the engineering direction on projects that genuinely matter
• Be the go‑to specialist – the one people trust for clarity, quality and technical judgement
• Work with multi‑discipline teams and influence how solutions are shaped from day one
• Coaching and developing talent – play a key role in growing capability, not just delivering tasks
• Flexibility and ownership – manage your own workload and make decisions without micromanagement
• Progression that reflects your contribution, not time served
• A culture that backs professionals – respect, openness and a real focus on engineering best practice

What you’ll be doing This role is about leading through expertise 
You’ll take on the most challenging engineering problems, guide teams through technical decisions, and ensure outputs are robust, safe and aligned with the agreed scope. You’ll build strong relationships with stakeholders, translate expectations into clear deliverables, and act as the steady technical voice others rely on.
You’ll also shape how engineering is done here: promoting best practice, championing safety, developing people, and sharing insight across projects. 

What you’ll bring

• Strong Mechancial engineering background, ideally with piping experience – this will give you a real edge
• Experience within the nuclear sector or another highly regulated industry – essential for the complexity and safety standards you’ll be working within
• Ability to obtain the required level of nuclear security clearance
• Confidence leading teams and tackling complex technical issues
• Clear communication, strong judgement and a collaborative, professional approach
