Accounts Receivable Specialist | Global Design & Architecture Consultancy | London

The Client

Harmonic are working with one of the world's most established architecture and design consultancies on their search for an Accounts Assistant with an accounts receivable/sales ledger focus to join the London finance team. The business is a genuine heavyweight in its field - working across a wide range of commercial, cultural, and civic projects at scale, with a large international team and a strong reputation built over several decades. The London office is home to a collaborative, high-performing finance function that sits at the centre of a creative, multi-disciplinary business. It’s a tight-knit team with a good culture, and one where people tend to stay long term - the Finance Director and Accounting Manager (which this role reports into) have been with the business a long time and know it inside out, which makes for a solid environment to develop in.

The Role

This is an AR-focused role working across the UK and EMEA. Alongside the London team, you’ll be supporting the financial operations of the firm’s European offices - processing high volumes of cash receipts daily (upwards of 20 transactions per day across multiple currencies), producing daily liquidity reports to the Finance Director across multiple bank accounts, and owning the end-to-end AR cycle: downloading bank reports, mapping payments to specific invoices, notifying project stakeholders, and ensuring accurate system allocation. The multi-currency and multi-entity dimension is real, and previous exposure to both is important. Beyond cash management, you’ll act as the subject matter expert for weekly timesheet submission and reconciliation in Deltek VantagePoint, run complex month-end reporting including balance sheet reconciliations, fixed asset monitoring, and credit card audits, and provide cover for AP payment runs and employee expense approvals - verifying VAT, GL codes, and project-specific reimbursable back-up. It’s a hands-on role that moves at pace, and the team is looking for someone who takes ownership quickly rather than waiting to be directed.

Key Responsibilities

• Deliver daily liquidity reporting across multiple bank accounts to the Finance Director
• Process high volumes of cash receipts daily, mapping payments to invoice numbers and ensuring accurate system allocation
• Manage the end-to-end AR cycle across the firm’s European offices, including collections and aged debt monitoring
• Act as subject matter expert for weekly timesheet submission and reconciliation in Deltek VantagePoint
• Execute month-end balance sheet reconciliations, fixed asset monitoring, and credit card audits
• Support project accountants with reimbursable back-up documentation, verifying VAT and GL codes
• Provide cover for AP payment runs and employee expense approvals
• Identify and implement improvements to processes and internal controls

What our client needs to see (essential)

• 2-5 years of general accounting experience, with a clear focus on Accounts Receivable/Sales Ledger
• Experience working in a multi-currency environment (EMEA, France, Germany)
• Highly organised with the ability to manage high transaction volumes accurately and at pace
• Solid Excel skills and comfort across the MS Office suite
• Clear communicator - able to manage priorities and deal with stakeholders at all levels
• Proactive and ownership-focused approach to the role

What we’d like to see (desirable)

• Background in professional services, architecture, engineering, advertising, consultancy, construction, real estate, or a project-led environment
