The Business

Harmonic are excited to be working with an extremely high growth Cleantech scale-up in their search for a Group Finance Manager to join the team on a 12 month fixed-term basis.

The business has developed a cutting-edge device for reducing fuel consumption in the transportation industry. They are the only business to have proven their technology in the space and have the revenue growth to reflect their market dominance. They have grown revenue from £2m in 2019 to over £60m now with limited external investment.

The company culture is incredibly high performing but friendly. Everyone is working towards a common goal and there are no huge egos in the room. They remain in a hybrid working model.

The Role

Reporting directly to the Financial Controller (but working closely with the VP Finance, CFO and other departments), the Group Finance Manager will oversee the day-to-day accounting operations, including treasury, tax, and managing the Accounts Assistant. They will lead both the Dutch group audit and the UK audit, including preparing the statutory financial statements. The role involves handling regular, calendar-driven tasks that a qualified accountant would typically manage in a small, well-rounded finance team.

Responsibilities:

• Lead month-end accounting processes including balance sheet preparation, journal postings, and reconciliation of key accounts.
• Oversee daily and weekly cash management activities, including cashflow forecasting and investment tracking.
• Act as the finance lead for the company’s foreign entity, working with local accountants to review monthly reports, manage funding, and oversee compliance.
• Support the preparation of tax filings and submissions, including VAT returns, R&D tax credit claims, and corporation tax.
• Maintain oversight of accounts payable processes, including reviewing payment runs, bank reconciliations, and supplier data.
• Assist with governance and administrative tasks, such as company secretarial filings, pricing updates, and managing corporate cards.
• Manage the full statutory audit process for both UK and Dutch entities, including preparing financial statements, coordinating with auditors, and responding to queries.
• Contribute to ad hoc finance projects and provide support to senior finance leadership as required.

What we need to see:

• Qualified Accountant (ACCA, CIMA, ACA or equivalent)
• Experience with NetSuite accounting software (highly desired)
• Intermediate Excel skills for report building and analysis
• Strong communication and influencing skills
• Confident holding people to account and implementing change where needed
• A team player who will be working with the wider business and the rest of Finance
• Pro-active, entrepreneurial 'can do’ attitude with exceptional attention to detail
• Inquisitive to learn and develop
