• Contributing to finance and CRM systems development, and leading finance systems induction and training for staff.
• Helping to shape and update finance policies and procedures.

What we are looking for:

• Proven experience supporting a finance function in an SME or charity.
• Strong numeracy, attention to detail, and experience with purchase ledger, sales ledger, bank reconciliations and month-end processes.
• Confidence working with finance systems, and comfortable adopting new digital tools (experience with Microsoft Dynamics Business Central, Continia or Jet Reporting is a plus).
• AAT qualified, or actively studying towards AAT, is desirable.
• A clear communicator who can explain financial information to colleagues at all levels.
• Someone who shares our values, works well collaboratively, and takes pride in getting things right.

Why join us:

• 28 days' annual leave (pro rata) plus bank holidays, rising to 30 (pro rata) after two years.
• Group pension scheme with 6% employer contribution.
• Group life assurance and healthcare cash plan.
• Employee Assistance Programme and discounted gym membership.
• Employee volunteer days.
• Free car parking at SIA House.
• Genuine investment in your development, with a dedicated budget for training and growth.
