Job Description

Reporting to the Group Financial Controller, you’ll play a key role in ensuring the accuracy, integrity, and user access control for our master data across Jellyfish’s finance systems. Working closely with the Finance Team in London, you’ll maintain and improve our Enterprise Resource Planning (ERP) systems, with an initial focus on reviewing and cleansing key finance master data sets to deliver accurate and fully controlled data that underpins our financial operations.

Please note that this will start as a six-month, full-time, fixed-term position, with a gross monthly salary of GBP 2,500–2,900.

There is potential for the role to evolve beyond the initial six months. You may have the opportunity to help shape the position and collaborate with the Operations Team on cross-departmental master data challenges.

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.
