Amentum is currently recruiting for a Digital Engineer (Inventor) to join our Energy business, which is entering an exciting phase of opportunity supporting new small and advanced modular reactor developers internationally. Our work is varied, covering nuclear projects (Licensing, New Build, Generation, Life Extension, and Defueling). 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.

This is an excellent opportunity for someone with a background in engineering design, CAD, BIM, modularisation and/or digital engineering who has hands‑on experience using Autodesk Inventor and wants to support modular project delivery. You will develop and coordinate accurate 3D models, assemblies, fabrication drawings, bills of materials and installation information for integrated mechanical, electrical, piping and instrumentation modules.

The ideal candidate will have practical Autodesk Inventor experience, a good understanding of engineering design and fabrication processes, and the ability to work confidently across multi‑discipline modular engineering teams. Experience with modularisation, Autodesk Vault, iLogic/parametric modelling, Navisworks, Plant 3D, common data environments or digital handover would be advantageous.

• Developing and updating Autodesk Inventor 3D models, parts, assemblies, sub‑assemblies and modular design packages.
• Supporting modularisation, including module breakdown, boundaries, interfaces, access, lifting/handling, transport constraints, installation sequencing and site tie‑ins.
• Modelling and coordinating integrated mechanical, electrical, piping and instrumentation modules, including skids, fabricated frames, pipe racks, equipment packages, cable containment, instrument supports and local panels/junction boxes.
• Producing and checking general arrangement, fabrication, manufacturing, assembly, installation, interface/tie‑in drawings, exploded views, bills of materials, parts lists and material schedules.
• Interpreting design briefs, specifications, P&IDs, line lists, equipment data sheets, cable/instrument schedules, vendor information, surveys and engineering calculations.
• Working with engineers, designers, fabricators, suppliers, construction and site teams to resolve buildability, clash, access, maintenance and interface issues.
• Ensuring model data and drawings are accurate, controlled, revision‑managed and aligned with company/client CAD, BIM, document control and quality requirements.
• Supporting design reviews, clash and constructability reviews, factory assembly/pre‑commissioning, as‑built updates, digital handover and improvement of Inventor templates, libraries and workflows.
