About Fonix
Fonix is a fast-growing, publicly listed payments and messaging technology company. We help some of the biggest brands engage customers and take frictionless mobile payments, with operations spanning the UK, Ireland, France, Switzerland, and Portugal. Our finance team is small and fast-paced, and this role is a great fit for someone part-qualified who's ready to develop their finance career.
The Role
You'll own the preparation of management accounts for our growing French subsidiary, handling balance sheet reconciliations and VAT across multiple territories, including regular contact with accountants and advisors in different territories.
Alongside that, you'll flex into day-to-day finance operations when the wider team needs an extra pair of hands. It's a great opportunity to broaden your experience across international entities while turning your exam knowledge into real, hands-on experience.
What You'll Be Doing
Reasons to use Rodeo
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.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
