- Communicate regularly with Quality in Design, Design for Manufacture and R&D engineering teams.
- Provide practical test evidence and technical feedback to support design improvement activities.
- Contribute to design reviews by highlighting validation risks, testability issues and manufacturing considerations.
- Support corrective actions and design changes by reproducing faults, validating fixes and documenting results.
- Industrialisation and manufacturing test support
- Work alongside Industrialisation teams to define and implement test protocols for manufacturing.
- Support the development of production test methods, test limits and acceptance criteria.
- Assist with the transfer of test knowledge from R&D into manufacturing and production environments.
- Provide engineering support during prototype, pre-production and early production build phases.
- R&D administration and process support, secondary responsibility
- Support adherence to established R&D workflows and approval processes, acting as a point of contact for documentation and procedural queries where appropriate.
- Maintain accurate and up-to-date project files, technical documentation and administrative records connected to R&D and test activity.
- Organise and archive compliance-related paperwork and internal reports to support clear traceability.
- Manage purchase orders, supplier documentation and internal requests when required to support R&D delivery.

Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
