Interim Treasury Manager | Fast-Growth Retail & Ecommerce Brand | London/Hybrid

Harmonic are delighted to be working with an exciting, high-growth consumer business within the FMCG, ecommerce and retail space, in their search for an experienced Interim Treasury Manager to join for an initial 6-month contract (outside IR35). The business has seen rapid expansion in recent years and is continuing to scale both in the UK and internationally.

This role will suit someone with a background in ecommerce, FMCG or retail, who thrives in a fast-paced, entrepreneurial environment and enjoys building structure and implementing processes from the ground up.

The Role

Reporting directly into the Finance Director, this is a key role responsible for driving efficiency, control, and visibility across cash, liquidity, and treasury operations. You'll take ownership of treasury processes, ensuring the business is well-positioned to manage growth, financing, and risk effectively.

You'll also play a pivotal role in developing the treasury framework — shaping how the business monitors cash flow, manages risk exposure, and builds robust processes to support scalability.

Key Responsibilities

  • Oversee daily cash positioning, forecasting, and liquidity management to ensure optimal working capital levels.
  • Lead the development of cash flow forecasting models and provide insightful reporting for leadership and board review.
  • Manage and optimise banking structures, facilities, and relationships to support growth and improve financing flexibility.
  • Implement strong treasury policies, controls, and operational procedures to enhance governance and mitigate risk.
  • Support financing activities — including arranging facilities, managing covenants, and evaluating funding options.
  • Monitor and manage financial risks (FX, interest rate, credit), introducing hedging strategies where relevant.
  • Collaborate with finance and commercial teams to ensure accurate reporting and compliance with accounting standards.
  • Continuously review and streamline treasury operations, identifying opportunities to improve efficiency and visibility.

What We Need to See (Essential)

  • Prior experience in a Treasury or Finance leadership role, ideally within FMCG, Retail, or another fast-paced industry.
  • Demonstrated success in building or enhancing treasury processes and controls.
  • Strong analytical and problem-solving skills with a proactive approach.
  • Excellent stakeholder management skills with confidence dealing with senior leadership and external partners.

£400–550 per day (Outside IR35)

Length of Contract:
6 Months

Start Date:

Location:
