Senior Group Accountant

A well-funded deep-tech business building hardware and AI products for industrial customers, having raised over $100m in its Series A from leading VC investors. It is moving from R&D and prototypes into production, operates across multiple international entities including the US, and is building its finance function to public-company standards.

Reporting to the Global Financial Controller, this is a hands-on Senior Group Accountant role covering monthly and statutory reporting and group consolidation across the group's global entities. You will run the close, own the consolidation and the external audit, and lead technical accounting as the business moves into manufacturing, including inventory, standard costing and the transition from FRS 102 to IFRS.

Much of the close, audit and controls framework is still to be built, so this suits an audit-trained accountant who wants to set those foundations rather than inherit them.

• Run the month-end and year-end close, owning journals, accruals, prepayments, fixed assets, payroll postings and full balance sheet reconciliations
• Operate and improve the group consolidation across all entities, including intercompany reconciliations, eliminations and multi-currency translation
• Prepare monthly management reporting and group cash flow reporting for leadership, investors, lenders and auditors
• Prepare UK/US statutory financial statements and support local filings in other jurisdictions alongside external advisors
• Own the external audit end to end, including PBC lists, auditor relationships and technical position papers
• Write technical accounting papers on complex transactions and develop policies across revenue, inventory, R&D, leases and share-based payments
• Lead inventory and manufacturing cost accounting as the business moves into production, including standard costing, cost of sales and stock provisioning
• Build and document internal controls, play a central role in the ERP build-out, and use AI and automation to speed up the close and reconciliations
• ACA, ACCA or CPA qualified (CIMA considered), ideally trained in an audit firm
• 4+ years' post-qualified experience across multi-entity, multi-currency groups, ideally including US entities (US GAAP).
• Strong technical knowledge of FRS 102 and IFRS, with experience preparing statutory accounts and managing external audits end to end
• Hands-on close and consolidation experience, owning journals, reconciliations, intercompany and eliminations rather than only reviewing them
• Inventory and cost accounting experience, including standard costing, in a manufacturing, physical goods or high-volume environment
• Experience in a high-growth business where processes, controls and documentation still need to be built
• ERP implementation experience (e.g. Net Suite, SAP)
• Background in a venture-backed hardware, robotics or deep tech business
• Confident using AI and automation tools to speed up close and reporting
