Management Accountant | Global Creative Agency | London / Hybrid

The Client

Harmonic are delighted to be partnering exclusively with a leading communications agency whose client base are B2B tech businesses across the US, EMEA, and APAC. Following a recent acquisition, the business has entered an exciting period of evolution, with projected growth of 5-10% YOY.

The business works predominantly on a retained business model, with roughly 100 ongoing EMEA projects at any given time. In this role, you'll report to the Financial Controller who is a brilliant mentor, and work closely with a highly commercial CFO. The role sits in a wider finance team of 5, and headcount of 50 in their beautiful Central London offices.

The business are rolling out a new ERP system, processes are being sharpened post-integration, and there is clear appetite from the leadership team to invest in and develop the right person over time.

The Role

This role is an excellent opportunity to gain broad exposure across commercial finance and management accounting (UK and international), whilst working across a tight-knit team and a business that genuinely values finance and sees the team as a key partner in their decision-making.

You'll own two distinct areas of work: revenue accounting across a high-volume client portfolio, and core management accounting including month-end close, accruals, prepayments, fixed assets, and VAT. This role would suit an experienced qualified or part-qualified accountant, with great benefits and study support on offer.

Responsibilities

• Lead month-end close across multiple European entities, including accruals, prepayments, and fixed assets
• Prepare and submit VAT returns
• Deliver consistently to non-negotiable monthly deadlines and take real ownership of the finance cycle
• Operate effectively across a multi-system environment, maintaining clean and reliable outputs throughout
• Contribute to an ongoing ERP migration alongside dedicated project resource, helping to embed new processes as they go live
• Act as a trusted finance business partner across the agency, building strong relationships with non-finance stakeholders
• Identify and support process improvements as systems consolidate and workflows become more streamlined

What our client needs to see (essential)

• Part-qualified or qualified accountant (ACA, ACCA, CIMA, or equivalent)
• At least two years of management accounting experience, with direct ownership of month-end close
• Experience with revenue recognition in a time-based model - agency, consultancy, or professional services background preferred
