Finance Operations Specialist in Basingstoke

Nomios' mission is to build a ‘secure and connected’ future, focusing on delivering top-tier cyber security services to our customers. Organisations across the globe depend on us to secure their digital infrastructures. In support of our continued growth, we are seeking a Finance Operations Specialist to join our team to own day‑to‑day financial administration processing activities. This role offers an exciting opportunity for a high‑potential, energetic, and dedicated individual looking to advance their career within a company poised for sustained growth in the years to come.

Your role as Finance Operations Specialist:

This is a hands‑on finance operations role focused on keeping day‑to‑day processing running smoothly and accurately. You will take ownership of accounts payable and expenses processing (including the full process, from processing invoices to payment), and you will support the wider finance team by maintaining a clear audit trail and strong financial controls. Alongside accounts payable and expenses, you will provide broader support across finance operations, including elements of accounts receivable administration and banking activity. This role is not responsible for producing statutory accounts or owning the full month‑end close; instead, you will provide high‑quality processing support, escalated exceptions, and help the Finance Director and wider team by ensuring information is complete, compliant and on time. You will also support continuous improvement by spotting recurring issues, suggesting practical fixes, helping document processes, and supporting testing/training when workflows or systems change.

Key responsibilities include:

• Accounts Payable (AP): receive and process supplier invoices; validate required back‑up (e.g., PO/approval/receipt where applicable); code accurately; resolve queries; and ensure timely posting.
• Expenses: process employee expense claims in line with policy; check completeness/receipts; follow up on missing information; and ensure correct coding and approvals.
• Supplier & master data: maintain accurate supplier records (including payment details); support supplier set‑up/changes in line with controls; and maintain a clear audit trail for updates.
• Payment run support: prepare payment runs for review/approval (including proposed payment lists, supporting documentation and exception notes) and coordinate timely query resolution with internal stakeholders and suppliers.
• Accounts Receivable (AR): support the AR process by ensuring accurate and timely posting of sales invoices into the accounting system, in coordination with the Sales Operations team.
• Close support (banking & month‑end): post bank transactions and support bank reconciliations by matching items and escalating exceptions; assist with month‑end activities as required.
• Controls, compliance & audit readiness: follow delegation of authority and payment approval controls; ensure documentation is complete and retained; and support internal/external audit requests.
• Continuous improvement: identify recurring issues (e.g., late approvals, missing POs, coding errors); propose practical improvements; help document procedures; and support testing/training when processes or systems change.

AAT‑qualified (or studying) and/or equivalent practical experience in a finance assistant / finance operations role. Proven experience in accounts payable and/or expenses processing, including query resolution and approval chasing. Good working knowledge of finance processes, reconciliations support, and the importance of financial controls and audit trail. Strong Excel skills and confidence working with finance systems and data. Highly organised with the ability to manage a busy workload, prioritise deadlines, and maintain attention to detail. Confident communicator with the ability to build strong working relationships across the business and with suppliers. Reliable and proactive, with a can‑do attitude; comfortable following defined processes and suggesting practical improvements.

Nice to have: experience supporting month‑end close and/or bank reconciliations.

• Hours: Full‑time, Monday‑Friday, 9:00am-5:30pm.
• Travel: Occasional travel may be required to other Nomios offices in Europe.
