The Client

Harmonic are excited to be working with a fast-growing, FCA-regulated consumer credit business that has more than doubled its revenue over the past year and expanded its headcount significantly in the same period. It's a great stage to join, with real investment going into building out the finance team. For an ambitious early-career finance professional, this is a chance to build strong accounting fundamentals while learning how reporting, controls, payments, audits, data and regulation come together in a real fintech environment.

The Role

This Assistant Accountant role has been created to support the company's internal accountant as the business continues to grow. You will keep the day-to-day finance operation running smoothly, posting bank transactions, processing supplier invoices and owning regular bank reconciliations, while building genuine hands-on exposure to month-end close: journals, accruals, prepayments and balance sheet schedules. You will support month-end reporting packs, variance analysis, budgets and forecasts, and help keep the team's records audit-ready. You will be joining a small, hands-on finance team where your work will be visible, your ideas will be heard, and you will get exposure to the finance engine behind a rapidly scaling financial services business. There is a genuine path to progress, with a hiring manager who is invested in developing you.

Key Responsibilities

  • Post daily bank transactions accurately and on time
  • Process supplier invoices, receipts and payment records with a strong focus on accuracy and controls
  • Support the accounts payable process, including invoice coding, supplier statement checks, queries and payment run preparation
  • Own regular bank reconciliations across company accounts and payment platforms, investigating and escalating differences
  • Gain hands-on exposure to month-end close, including journals, accruals, prepayments and balance sheet schedules
  • Support month-end reporting packs, variance analysis, budgets and forecasts
  • Maintain organised finance records and working papers so the team is ready for audit, internal review or regulatory requests
  • Support process improvements and finance projects as the business scales
