Financial Accountant – SAP S/4HANA Implementation £550.00 - £600.00 per day Umbrella Milton Keynes (2 Days per week) Contract until end of year (likely extensions)
We are seeking an experienced Financial Accountant with proven SAP S/4HANA implementation experience to support a number of strategic finance transformation programmes. This role will act as the Finance SME within project delivery teams, ensuring that finance requirements, accounting treatments, reporting needs and control frameworks are effectively designed, tested and implemented within new systems and processes.
The successful candidate will have previous hands-on experience supporting or delivering SAP S/4HANA implementations within a finance environment and will be comfortable working alongside project teams, business analysts, developers, testers and key finance stakeholders. This is a project-focused role and not a traditional operational accounting position. The successful candidate must be able to contribute immediately, bringing practical experience gained from previous finance system implementation programmes.
Key Responsibilities
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.
