Management Accountant
Swansea, South Wales | Full-time, office-based | £42,500 – £45,000 per annum
At Castell, we're passionate about building high quality social homes and communities and we're growing fast. With a secured land pipeline set to deliver 40% year-on-year growth over the next few years, we're looking for a hands-on Management Accountant to join us as we build the infrastructure our finance team needs to support that ambition.
About Us
Castell is part of a Welsh housing developer founded in 2019 with a simple mission: to help solve the housing crisis by delivering affordable, high quality, disability-adapted homes in partnership with housing associations and local authorities. What started as a small team has grown into a business of over 70 people, having already delivered hundreds of homes across South Wales with hundreds more currently on site.
The Role
The Management Accountant is the technical engine of our monthly close. You'll own accounts preparation across the Group, accounts receivable, all month-end journals, the balance sheet reconciliation schedule, intercompany accounting, SPV accounts preparation, payroll and related taxes (CIS, VAT, PAYE), and our monthly cost & valuation reporting.
This is a demanding, deadline-driven role in a fast-growing construction business — ideal for someone who enjoys ownership, structure, and getting the detail right, while helping shape the finance processes that will scale with us.

- Track Companies House filing deadlines across all SPV entities

- Support the year-end audit, including samples, evidence and working papers
What We're Looking For
- Part-qualified or qualified accountant (CIMA, ACCA or equivalent), or equivalent experience
- Solid month-end close experience, including balance sheet reconciliations and journals
- Experience with payroll, CIS and VAT
- Construction, property development or SPV-based accounting experience is a strong advantage
