Finance Assistant

About the role

Zinc is growing fast and its finance operations need to keep pace. We are hiring a Finance Assistant to take full ownership of day‑to‑day AP/AR, mailbox management and debt chasing. You will keep invoices moving, mailboxes clear and debtors chased, turning a process that currently takes days into one that takes hours, working closely with our Senior Finance Manager and with a clear path into a broader finance career.

• Run weekly reconciliations across accounts.
• Own debt chasing, proactively keeping debtor days down.
• Deliver the monthly invoicing cycle and manage overages.
• Own accounts payable end‑to‑end: process supplier invoices, raise payment runs, ensure correct coding, approvals and timely payment.
• Help close the books on a tight cadence (OPEX by WD1, revenue by WD3).
• Assist with VAT returns and other routine statutory and compliance filings.
• Use Zinc’s tools (Xero, HubSpot, Stripe, Sigma) and AI tools like Claude to work efficiently.

Required profile

• 6 months–1 year experience in a finance role such as AR Assistant, Credit Controller, AP Assistant or Finance Assistant.
