The Opportunity

Reporting directly to the Change Implementation Team Lead, you will act as a vital line of defence to ensure absolute design integrity and producibility. This comprehensive role offers deep day‑to‑day variety. Managing modifications across a wide range of products including machined mechanical components, textiles, pyrotechnics, and complex mechanisms gives you excellent engineering breadth and exposure.

What You’ll Do

• Engineering Change Management: Process engineering change requests, perform rudimentary impact analysis, and coordinate with the change review board based on the affected parts.
• CAD Modelling & Drafting: Generate and modify 3D CAD models and related Product Manufacturing Information (PMI), ensuring engineering data is fully defined but unambiguous.
• System Traceability: Accurately input, maintain, and monitor engineering data and release statuses within our Teamcenter PLM system and bespoke SBM platform.
• Producibility & Liaison: Partner directly with the Production Engineering Department to align datum and tolerance schemes with strict manufacturing and inspection requirements.
• Analysis & Calculation: Use basic engineering principles to conduct tolerance and clearance analyses, mass optimization, and preliminary sizing calculations.
• Legacy Product Sustainment: Reverse engineer older product data into modern formats and standards to aid in the long‑term support of existing products.

What We’re Looking For

• Engineering Baseline: An engineering or applicable science‑based degree, or an Engineering HND backed by relevant industry experience.
• Tolerancing Expertise: A strong, fundamental understanding of Geometric Dimensioning and Tolerancing (GD&T) principles.
• Change Principles: Solid comprehension of configuration management and engineering change processes.
• Technical Literacy: Experience using a PLM or PDM‑type database. Exposure to 3D CAD modelling software is required, while Siemens NX experience is preferred.
• The Mindset: Sound numerical and verbal skills, a proactive approach to Design for Manufacture and Assembly (DFMA), and a keen eye to minimize design iterations.
• Share and demonstrate the Martin-Baker values.
