Job Description
We are seeking a Lead MBSE Engineer to take ownership of the Model-Based Systems Engineering (MBSE) strategy for a first-of-a-kind commercial fusion power plant programme. This is a unique opportunity to act as the technical authority for MBSE capability, working across the organisation and its partners to deliver the landmark STEP (Spherical Tokamak for Energy Production) programme.
The Role
As the MBSE lead, you will define and deliver a transformational MBSE capability, enabling the successful execution of one of the most ambitious engineering programmes in the world.
Working closely with the Systems Engineering Manager and diverse technical teams, you will articulate a clear MBSE vision, develop a pragmatic implementation roadmap, and champion best practice across the organisation.
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.
