The role will focus on engineering planning, technical governance, configuration management, design reviews, and acceptance evidence management. The engineer will act as a focal point between technical disciplines, ensuring engineering activities are appropriately planned, controlled, and evidenced in support of programme milestones and customer acceptance.
Experience within naval, maritime, or combat systems environments is desirable, particularly where candidates have supported complex platform or mission-system development programmes.
The initial project is remote working with occasional onsite meetings and workshops at any Expleo office (Preston, Derby, and/or Bristol).

- Coordinate responses to review comments, technical queries, and customer observations.
- Collate, structure, and manage acceptance evidence to demonstrate contractual compliance and support customer acceptance activities.
- Support verification, validation, and certification activities by maintaining requirements traceability and evidence repositories.
- Review acceptance evidence against Verification Cross Reference Index (VCRI) requirements and identify gaps, risks, and evidence shortfalls.

- Support audits, baseline reviews, and programme assurance activities.
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.
