Product Definition Engineer – Role Overview
Product Definition Engineers are responsible for the output of high‑quality Engineering Definitions and CAD Master Models across the UK Defence product base. They ensure that the technical and safety integrity of a design is maintained in accordance with company procedures, and that components satisfy fit, form and functional requirements while being optimised for manufacture.
Responsibilities
* Prepare, develop and maintain 3‑D master CAD models, relevant documentation, Model Based Definitions (MBDs) or technical drawings to meet engineering standards and downstream requirements.
* Manage and incorporate Drawing Alteration Requests (DARs), concessions and continuous design updates.
* Create specialised bespoke models for analysis or manufacturing purposes.
* Collaborate to ensure component definitions are aligned with design intent and manufacturability.
* Produce tolerance stack‑ups to support new product validation and in‑service investigations.
* Actively promote, encourage and support the identification and implementation of continuous improvement (of tools, processes, methods and guidance material).
At Rolls‑Royce we put safety first, do the right thing, keep it simple and make a difference. These principles guide our behaviours and are integral to our assessment process.
Qualifications
* Proficiency in Siemens NX and Teamcenter (other CAD and PLM tools will be considered).
* Experience using ISO/British Standard and/or ASME Y14.5 GD&T and drawing standards, and appropriate engineering experience in conceptual and detailed design and drafting techniques.
* Degree qualification in a STEM subject and/or relevant engineering experience (Mechanical, Aeronautical, Electrical or Controls). Other qualifications combined with relevant experience may also be considered.
* Strong technical, analytical and problem‑solving skills, with a systems‑level mindset.
* Understanding of manufacturing processes.
* Ability to plan and deliver to challenging deadlines.
* Ability to work accurately and at pace.
* Self‑motivation and an ability to drive for results.
* Strong communication and interpersonal skills to contribute effectively in a team environment.
To work for the Rolls‑Royce Defence business, an individual must hold a Security Check clearance. Rolls‑Royce will support the application for Security Clearance if you do not already have this in place. Due to the nature of the work, the business can only progress applications from individuals who are UK nationals or, in MoD approved cases, dual nationals.
