**About the Opportunity**
Amentum is currently recruiting for a Senior 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.
**And this is where you come in**
Your role will be to support 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 Principal Engineers, Engineering Managers and Operations Managers to enable delivery of maximum value.
**People are at the heart of everything we do**
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, Bristol or Knutsford). We put flexibility at the heart of what we do and we're happy to consider flexible working patterns. Key responsibilities could include:
+ Lead the development of civil and structural engineering designs and solutions across the full project lifecycle from bid generation, through concept and detailed design development to construction.
+ Prepare technical documentation, specifications, and design justifications for safety-critical systems
+ Oversight, verification and preparation of safety case inputs, such as Safety Functional Requirements (SFRs), Structural Design Method Statements (SDMSs) and Design Substantiation Reports (DSR).
+ Oversight, verification and preparation of Interpretive Reports, Basis of Design, Analysis Reports, Calculations, CDM documentation, Material Specifications, Scopes of Work, and Technical Reports
+ Perform analysis and/or design tasks as necessary.
+ Demonstrate knowledge of the practical aspects of implementing engineering designs and understand the use of standards and compliance with regulatory requirements in an engineering environment.
+ Work with international Small and Advanced Modular Reactor developers to pass through the Office of Nuclear Regulation's Licencing process.
+ Manage and check deliverables from junior engineers to ensure compliance and quality.
+ Provide technical guidance and mentorship to less experienced engineers.
+ Interface with clients, regulators, and project stakeholders on technical matters.
+ Ensure designs meet nuclear safety, cybersecurity, and quality standards.
+ Support project planning, cost estimating, and risk management activities.
+ Produce high-quality technical reports.
+ Build and maintain valuable relationships with clients, partners and peers.
Skills and Qualifications (the following list outlines desirable skills and qualifications. While these attributes are valued, we understand that applicants may not possess all of them. We therefore encourage applications from individuals with relevant experience and potential):
+ MEng, MSc, BEng or BSc or equivalent in civil engineering or another relevant discipline.
+ Chartered or near Chartered Engineer status with a relevant professional body (we will support you).
+ An awareness of civil nuclear plant systems, structures and components and associated design and assessment guidelines (or relevant engineering principles from other highly regulated industries).
+ Knowledge or civil engineering principals, design tools and relevant guidelines, standards and practices (in particular American standards ACI, ASCE and AISC).
+ Ability to simplify complex problems.
+ Experience using finite element modelling software and associated post processing software, with experience in validation and verification of modelling tools and their outputs.
+ Good knowledge of health and safety legislation and good practice.
+ Understanding of the use of design tools within a BIM environment.
+ UK Nuclear Licencing and Generic Design Assessment process experience is desirable
+ Experience in producing and checking high-quality technical deliverables

We have to look beyond code checks to get a deeper insight into structural response and failure mechanisms, considering ductility, nonlinear buckling, and soil structure interaction. We work things out as a team, starting from first principles, researching methodologies, challenging assumptions, thinking outside the box, and constantly learning. This role provides a fantastic career opportunity, whilst developing your skills and experiences under the guidance and mentorship within our central systems engineering team.
Take your existing skills and join our team, locations can be hybrid, nationwide with main office locations, Glasgow, Reading, Bristol, Warrington, Site visits are expensed and occasional.
