Overview

Quantum Detectors is entering an exciting phase of growth and innovation, and we’re looking for a trusted, influential, and hands‑on Head of Finance to guide us through it.

Take full ownership of the finance function at a growing, globally active technology company. This is a hands‑on role with genuine strategic impact — ideal for someone who enjoys both running day‑to‑day finance operations and working closely with the CEO on high‑level planning.

Why This Role Matters

Our products power scientific discovery at world‑leading research facilities. Your work will power us, ensuring we scale sustainably, make smart commercial decisions, and stay financially strong as demand for our technology grows.

You’ll be the CEO’s trusted finance partner and a key voice in investment, planning, and strategic decision‑making—and you’ll still enjoy rolling up your sleeves and keeping our books clean, accurate, and insightful. You will be responsible for in‑sourcing core tasks from external providers and establishing a scalable, resilient internal finance function with impeccable controls.

Key Responsibilities

• Manage all daily finance operations (AP/AR, payroll, reconciliations, expenses)
• Lead budgeting, forecasting, month‑end and year‑end close
• Produce financial reports, cashflow forecasts, and management accounts
• Create financial models to support strategic decisions
• Partner with the Senior Leadership Team on growth and investment planning
• Support grants, funding rounds, and investor reporting
• Maintain strong internal controls, processes, and financial policies
• Improve financial systems and reporting tools (Xero, ERP, Salesforce)
• Manage external accountants, auditors, and banking partners

Qualifications & Experience

• Fully qualified accountant (ACA, ACCA, CIMA)
• Experience in an SME or scale‑up environment
• Strong hands‑on finance control experience
• Confident with Xero, Google Sheets, and ERP systems
• Able to turn data into clear commercial insight
• Excellent communicator who can influence non‑finance stakeholders
• Experience with grants, investment rounds, or investor relations
• Comfortable owning the full finance function end to end

What We Offer

• £60,000-£80,000 DOE
• Hybrid working
• 30 days holiday + public holidays
• Enhanced pension
• 35‑hour week
• Modern facilities at Harwell Campus
• Opportunity to shape the finance function as the business grows

If you’re looking for a role that mixes strategic influence with hands‑on financial ownership - we’d love to hear from you.
