Grimsby, On-Site (5 days per week

Full time, Permanent

£30-35k DOE

Our client, a rapidly growing chilled food manufacturer supplying major supermarkets, is expanding its finance team to support continued business growth. This is an exciting opportunity to join a dynamic organisation that’s investing heavily in people, systems, and process improvement.

As Assistant Management Accountant, you’ll play a key role in a small, growing team of three, bridging the gap between the Head of Finance and a junior team member. You’ll support day-to-day financial operations, assist with management accounting, and help strengthen controls and reporting across the business.

Key responsibilities include:

• Supporting the month-end close, preparing journals, reconciliations, and management reports
• Assisting in budget preparation, forecasting, and performance analysis
• Managing daily banking, processing purchase and sales ledger transactions, and reconciling supplier accounts
• Coordinating weekly payroll data (for c.125 headcount) and liaising with the outsourced payroll bureau
• Participating in stock takes, costing analysis, and ensuring accuracy in stock and production reporting
• Producing key financial and operational reports — sales, debtors, headcount, and performance dashboards
• Mentoring the junior team member and supporting the Head of Finance as needed
• Contributing to process improvements as the business transitions to digital systems, Power BI, and a future ERP implementation

We’re looking for someone who brings energy, curiosity, and a drive to make an impact in a busy FMCG finance environment.

Essential:

• Minimum AAT Level 4 qualification (or equivalent experience)
• Experience within food manufacturing or FMCG environments
• Strong understanding of costing, stock control, and month-end accuracy
• Confident working in fast-moving, high-volume environments (7-day operational business)
• Experience with weekly payroll data and liaising with outsourced payroll providers
• Excellent attention to detail and strong Excel skills

Desirable:

• Exposure to Power BI, digital timesheets, or ERP systems
• Experience using Xero or similar accounting software
• A mindset focused on learning, continuous improvement, and innovation

If you’re analytical, hands-on, and ready to grow your career in a thriving FMCG business, we’d love to hear from you.
