At OQC

We aren't just theorising about the future; we're building it. Born from a philosophy of bold innovation, we've successfully transitioned quantum computing from an academic dream into a commercial reality. The most exciting thing is that we're just getting started and we've recently closed our £260 million Series C funding round which is the largest fundraise ever completed by a quantum computing company in Europe.

The Purpose

As OQC scales, our Finance function is evolving to meet the needs of an increasingly complex, international business.

As Financial Controller, you'll play a key role in strengthening our financial control environment, solving complex accounting and process challenges, and building scalable ways of working. This is a hands-on, delivery-focused role where you'll take critical finance workstreams from diagnosis through implementation, testing and handover.

The Role

Reporting to the Group Financial Controller, you'll operate with significant autonomy across financial accounting, control remediation, finance operations and process improvement.

You'll combine strong technical accounting expertise with a pragmatic, problem-solving mindset. Whether you're fixing an underlying control weakness, improving the close process, establishing finance operations for a new overseas entity or strengthening how NetSuite supports the business, you'll be expected to turn complex problems into robust, sustainable solutions.

The Group Financial Controller will retain overall accountability for Group reporting, statutory reporting, tax, treasury, material accounting judgements and the wider Group control environment.

This is an initial 6 month fixed term contract with the possibility of it becoming permanent.

What You'll Be Working On

• Lead financial-control remediation across areas including order-to-cash, procure-to-pay, payroll, fixed assets, financial close, reporting and finance systems, taking issues from root-cause analysis through to implementation and testing.
• Resolve complex accounting, reconciliation and reporting issues, replacing recurring manual fixes with sustainable processes and controls.
• Strengthen month-end, year-end and statutory reporting processes through improved reconciliations, working papers, review controls and technical accounting analysis.
• Design, document and embed scalable financial controls, procedures and accounting policies with clear ownership, evidence and segregation of duties.
• Establish finance processes, systems, reporting structures and controls for new overseas entities, working with internal teams and external professional advisers.
• Lead finance systems and process improvements, using NetSuite, automation and better data flows to improve accuracy, efficiency and scalability without compromising control.
• Act as a senior technical resource across Finance, challenging existing ways of working, supporting colleagues and ensuring improved processes transition effectively into business-as-usual operations.
