You'll sit at the intersection of engineering, production, quality, and suppliers, taking ownership of investigations, driving root cause resolution, and ensuring robust, manufacturable engineering solutions.

What You'll Be Doing

Technical Leadership & Collaboration

Represent Engineering at Level 1 & 2 QRQC meetings, providing clear technical direction and confident decision making
Work closely with OE and MRO teams to deliver high quality engineering solutions and supporting documentation
Act as a senior engineering point of contact across production, suppliers, assembly, and test teams

Production & Through Life Support

Support production teams to meet demanding build schedules by resolving engineering issues quickly and effectively
Lead engineering investigations, delivering clear, concise analyses and robust corrective actions
Demonstrate persistence and technical depth when tackling complex, high pressure engineering challenges

Design, Validation & Optimisation

Translate customer and internal requirements into robust mechanical designs
Apply calculations, analysis, and validation tools to verify and refine solutions
Ensure designs are optimised for manufacture, assembly, cost, and quality

Continuous Improvement & Governance

Lead detailed Root Cause Analysis (RCA) activities and drive corrective actions
Promote a culture of continuous improvement, both technically and behaviourally
Author, review, and approve engineering documentation throughout the through life support phase
Contribute to and report against engineering KPIs and budget targets

Strong background designing complex electromechanical products within highly regulated industries (e.g. aerospace)
Proven ability to analyse complex problems and deliver practical, high quality engineering solutions
Excellent written and verbal communication skills, comfortable engaging with stakeholders at all levels
Deep understanding of mechanical design principles, materials, and production methods
Experience leading investigations, RCA, and design assurance activities

Highly Desirable

Experience with rotating machinery, including motors and generators
Background across R&T, R&D, and NPI environments
Strong CAD/PLM capability (NX, CATIA, Teamcenter, Windchill)
Ability to interpret and challenge technical analyses (FEA, thermal, bearings, hand calculations)

Why This Contract?

12 month Inside IR35 engagement with a strong technical challenge
High visibility role with genuine influence on engineering outcomes
Opportunity to work within an advanced aerospace environment
Ideal for contractors open to relocating to Pitstone for a rewarding, hands on assignment
