Amentum is currently recruiting for a Principal Civil and Structural Engineer to join our Energy business, which is entering an exciting phase of opportunity: supporting a key client’s UK nuclear fleet through a business transformation; supporting new small and advanced modular reactor developers. Our work is varied, covering nuclear projects (Licensing, New Build, Generation, Life Extension, and Defueling), Renewable Energy projects and high energy industrial projects, such as data centres and hydrogen production facilities.

In addition, we have opportunities across the wider business to help us to keep work interesting as you develop your career with us.

We’re looking for a driven individual who embraces collaboration and diversity, and who shares our vision to create a secure and vibrant future by continuously reinventing, realising breakthroughs and taking on challenges with courage.

Our goal is to support development of new nuclear technologies and to keep existing power stations operating safely, contributing to the UK’s Net Zero carbon target.

Your role will be to manage and deliver civil and structural engineering solutions to time, cost and quality on projects of varying sizes. If you’re familiar with project delivery, you’ll know that they have lots of moving parts and complexity, which is why you’ll be working alongside our Engineering Managers and Operations Managers to enable delivery of maximum value.

Central to the success of the role will be your people skills, building effective relationships and interacting with multiple internal and external stakeholders in multiple locations.

You’ll also work closely with colleagues to support activities that offer the best service to the client. Through your interactions, you’ll be able to gather useful intelligence on client needs and work with the team to deliver innovative solutions.

You’ll utilise your strong communication and engagement skills to achieve client, people and business outcomes, working with your team and peers that are based in different locations across the UK.

We’re continuously evolving and growing the business, so there’s plenty of opportunity to evolve and grow your skills and career too.

This role will be based at one of our Energy offices (Newcastle, Warrington, Gloucester or Knutsford). We put flexibility at the heart of what we do and we’re happy to consider flexible working patterns.
