Amentum is the Design and Engineering partner for Sellafield under the PPP (Programme and Project Partners). This is a 20‑year arrangement to deliver ~£7bn of major projects. We are looking to recruit high‑value expertise from across regulated and comparable sectors to work in a collaborative environment. PPP is delivering major projects, site‑wide improvements and provision of supporting services.

The SNM Analytical Project is progressing into a critical phase of delivery, and we are looking for a proactive and collaborative Area Engineering Manager to support the safe and efficient transition of design into construction delivery.

Based at our offices in Cumbria, as an Area Engineering Manager (AEM) you will act as the key engineering interface to the onsite construction team, ensuring engineering outputs are aligned, coordinated, and ready to build.

• Leading engineering delivery for a defined SNM Analytical Project area, ensuring outputs are fully aligned with construction needs.
• Act as the day‑to‑day engineering interface for onsite construction teams, supporting issue resolution and enabling safe construction progress.
• Drive timely close out of technical queries, design changes, and construction clarifications.
• Support constructability reviews, build sequencing, and readiness assessments in line with PPP delivery practices.
• Maintain strong relationships across engineering, construction, safety, planning, and assurance teams.

• Experience in engineering management on major infrastructure or highly regulated projects.
• Strong understanding of multidisciplinary engineering and its interface with construction.
• Confident communicator who builds positive, collaborative relationships.
• Delivery focused mindset with the ability to manage emerging issues at pace.
• Chartership desirable, but not essential.

Our values are built on a strong foundation of safety, integrity, and respect for every individual. People are at the heart of our mission, and we believe in supporting one another through a culture of care and collaboration.

We strive to create a workplace where everyone feels they belong and can thrive. Supporting mental wellbeing and fostering a sense of connection are essential to how we work. When we embrace different perspectives and work together, we become more innovative, more agile, and more successful.
