The role
You'll be the person who takes ownership of the finance function at Mammoth and shapes how our business operates and scales. As a Financial Controller, you're leading the finance function day to day while bringing greater clarity, control and commercial insight into the business. This is a hands-on leadership role with real influence. It's ideal for someone ready to step into a No.1 position and shape the financial direction of a creative business.

About Mammoth
We're a brand consultancy that specialises in clever answers to challenging questions. We work with world-leading universities, life sciences organisations, environmental leaders and ambitious brands to help them define what they stand for, where they compete and what comes next. Our offices are in Belfast and London, and our clients are spread across the UK, Europe, Canada and the US.

Who you'll work with
Day to day, you'll manage and develop one team member. You'll also partner closely with the MD and Managing Partners on financial performance and planning. You'll work with external accountants to take ownership of VAT and corporation tax processes.

What you'll do
Own all core finance operations including invoicing, cash flow, forecasting and reporting. Lead budgeting cycles and profitability analysis across clients and projects. Improve systems, processes and reporting to support a growing agency. You'll bring greater clarity, control and commercial insight into the business.

What we're looking for
You're professionally qualified (ACCA, CIMA or ACA) with a degree in finance, accounting or economics. You have 5+ years of experience, ideally within an agency or project-based business. You have a strong working knowledge of Sage and agency management systems (Synergist preferred). You're comfortable operating across both detail and strategy. You're commercially sharp and astute, able to translate numbers into insight and influence decisions. You're ambitious with the appetite to grow into a broader finance leadership role over time.

What we offer
Finance sits at the heart of how we run the business, and this role is central to that. You'll work closely with the MD and Managing Partners on the decisions that matter, and you'll play a real part in shaping how the agency grows. Beyond that: 33 days annual leave including bank holidays plus your birthday off, hybrid working (3 days in the office, 2 wherever works), a city-centre office, a competitive salary, workplace pension and flexible hours when you need them.
