Head of Finance | High-Growth Technology Consultancy | Remote-First (London Preferred)
The Client
Harmonic is partnering exclusively with a high-growth technology consultancy that has scaled rapidly to c.£25m in revenue and is targeting 50%+ year-on-year growth. The business has built a strong reputation in its market, delivering technology-led consulting services to a blue-chip client base, and is now at an inflection point.
Until now, the finance function has been largely outsourced. With the business at this scale and trajectory, the company is bringing finance fully in-house and investing in the people, processes, and infrastructure needed to support the next stage of growth. There is a clear ambition toward a significant liquidity event in the medium term, and finance will be central to making that happen.
This is a genuine builder role - not a caretaker position. You will be creating the finance function from first principles, with real ownership, direct exposure to strategic milestones, and the backing to build a team around you as the business scales.
The Role
Reporting to the CFO, this is a broad, high-impact Head of Finance role spanning financial accounting, management reporting, FP&A, treasury, and wider finance transformation. You will be the most senior hands-on finance hire in the business, responsible for insourcing the finance function, building processes and controls from the ground up, and creating the reporting and commercial insight the leadership team needs to make informed decisions.
Beyond the core finance remit, you will partner closely with the CFO on strategic priorities including lender reporting, cashflow management, and preparations for future financing and exit activity. There is a clear pathway to building out a finance team beneath you as the business continues to grow.
This is suited to someone who has done this before - or is ready to. If you thrive on building structure where there is none, want first-hand exposure to a meaningful exit process, and are motivated by ownership over maintenance, this is worth a serious look.
Key Responsibilities
* Own the monthly management accounts process end-to-end, ensuring accurate and timely delivery of P&L, balance sheet, and working capital reporting.
* Lead the year-end process, coordinating statutory accounts preparation and managing the external audit.
* Build and strengthen the financial control environment from scratch, including reconciliations, accruals, revenue recognition, and process documentation.
* Develop and lead the budgeting, forecasting, and reforecasting cycle, partnering with operational and commercial stakeholders across the business.
* Take ownership of rolling cashflow forecasting and working capital management, identifying key risks and opportunities.
* Build financial models and analysis to support commercial decision-making, including pricing, profitability, resource planning, and scenario analysis.
* Support the CFO on strategic finance projects, including financing preparation, lender reporting, and covenant tracking.
* Oversee tax compliance across VAT, payroll tax, and corporation tax, working with external advisors where appropriate.
* Lead and develop the existing finance team, while shaping the future structure and capability of the function as the business scales.
* Drive continuous improvement across finance processes, systems, and reporting - embedding scalable ways of working that will support the business through its next phase of growth.
Essential Experience
* Fully qualified accountant (ACA / ACCA / CIMA or equivalent) with strong post-qualified experience.
* Demonstrable experience building finance processes and controls from first principles in a scaling environment - this is not a role for someone who needs established infrastructure to operate.
* Confident communicator who can partner effectively with senior stakeholders, commercial teams, and non-finance functions.
* Experience working in a scaling SME environment (c.£10m–£30m revenue), ideally with exposure to the pace and ambiguity that comes with rapid growth.
Desirable Experience
* Experience operating in a professional services, consultancy, or project-based business model.
* Previous exposure to exit preparation, investor diligence, or PE/VC-backed environments.
* Experience scaling or building a finance team alongside business growth.
