Mechanical Design Engineer
£50-52/hr Outside IR35
3-Month initial contract
Bristol, UK (Hybrid)
We're working with a Bristol-based engineering team on a fast-moving EV programme and are looking for a Battery Pack Design Engineer to take ownership of mechanical design work packages from concept through to delivery.
This is not a CAD-only role. You'll be trusted to own solutions, interpret requirements, manage interfaces and work closely with multidisciplinary engineering teams to deliver high-quality designs.
What You'll Be Doing
- Own and lead delivery of mechanical battery pack design work packages
- Gather, interpret and break down requirements before moving into detailed design
- Develop high-quality CATIA models and manufacturing drawings
- Work closely with CAE, electrical, thermal and other engineering teams
- Manage technical interfaces, risks, timing and design changes throughout delivery
- Apply strong GD&T and tolerancing principles to released designs
- Take designs from concept through to manufacturing/release
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.
