Finance Business Partner

About Isembard

Isembard is rebuilding industrial capacity through a connected network of factories. We bring skilled people, advanced machine tools and our own software, MasonOS, together to make precision components for aerospace, defence, energy and robotics.

The role

We are building Isembard's finance function from the ground up, and this role works directly alongside our Finance Director to do it. It is not a traditional business partnering role with settled processes and a large team.

From supplier payments and payroll to month-end, budgeting, cash flow and management reporting, you will run day-to-day finance while building the processes and systems that support our growth. One day you design a payment approval process; the next you run the payment cycle yourself.

• Own and improve supplier payments, invoice approvals, accounts payable and purchasing workflows.

• Support payroll across several countries so people are paid accurately and on time.

• Set up processes for expenses, reimbursements, supplier onboarding and payment terms.

• Help manage cash flow, working capital and short-term cash forecasting.

• Work with the Financial Controller on month-end: accruals, prepayments and reconciliations.

What you bring

• Part-qualified or qualified ACA, ACCA, CIMA or equivalent, or strong relevant finance experience.

• Experience in management accounting, finance operations, commercial finance or business partnering.

• A solid grasp of accounting fundamentals and month-end processes, and excellent Excel skills.

• Comfort moving between operational tasks and analytical, commercial work.

• Organised and resourceful, with strong communication across teams.

• Useful, not essential: startup or scale-up experience, a manufacturing or operationally complex environment, production costing and unit economics, or finance operations across several jurisdictions.
