Job Description
These Grade 6 Principal Service Designer roles operate at a strategic level within Digital Delivery, bridging policy design and digital delivery to ensure services are coherent, user-centred and deliverable.
The roles provide design leadership across multiple complex services, setting direction for service design activity and assuring quality across teams. By embedding systems thinking and user-centred design early in the policy lifecycle, these roles help prevent fragmented delivery, reduce the risk of costly rework, and ensure digital services are designed as an integral part of policy rather than as an afterthought.
Principal Service Designers work closely with programme directors, service managers and policy teams, as well as delivery partners, to shape end-to-end service outcomes.
The roles also involve leading and coordinating other service designers, aligning their work with the wider service landscape and helping to create a consistent experience across Defra services. Principal Service Designers will need to work as a close community, developing a shared understanding of services from the user’s point of view and looking beyond Defra’s organisational structures to identify how services connect in practice.

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.
