Join Oasis Project as our Finance Manager and play a vital role in an organisation that has been giving hope to women, children and families affected by drugs and alcohol since 1997.  

We are now looking for an experienced Finance Manager to oversee our financial operations and support strong, transparent governance across the charity. Working closely with the CEO, Senior Leadership Team and Board, you will ensure that our finances remain robust, accurate and strategically aligned with our mission.

You will lead on monthly financial reporting, quarterly management accounts, budgeting, forecasting and cash-flow management, providing the insight and assurance that enables effective decision-making. Your role will also include preparing year-end accounts, liaising with external auditors and maintaining sound financial controls that meet statutory, HMRC and Charity Commission requirements. 

You will oversee the bookkeeping and payroll functions, support the smooth administration of funding and income, and ensure that financial data is recorded accurately using Sage accounting software. You will work collaboratively with colleagues across HR, fundraising and operations, supporting them with financial information for bids, reports and service planning. Line managing the Bookkeeper, you will provide guidance, development support and oversight to ensure our finance processes run efficiently and in line with policy  

About you 

We are seeking someone with an accounting or bookkeeping qualification such as AAT or CIMA, or someone part-qualified and working toward completion. You will bring experience of charity accounting, strong working knowledge of Sage or a similar system, and the confidence to communicate clearly with colleagues, leaders and trustees. You will be organised, resilient and able to manage a varied workload while maintaining accuracy and professional boundaries. Strong IT skills, the ability to work both independently and as part of a team, and a reflective, adaptable approach are also essential. 

If you want to bring your financial expertise to a purpose-driven organisation and help sustain services that make a profound difference to women and families, we would love to hear from you.

About us  

We give hope to people affected by drugs and alcohol. We help women, children and families find the strength and opportunities to make choices that lead to change. Not just for themselves, but for their families, their friends and their communities. For all of us.  

We treat the person, not just the problem. We don’t ‘fix’ or rescue anyone. Instead, we give women hope that things can be better, and the tools to make changes. We understand that people aren’t always straightforward – and that a tough start in life doesn’t have to mean a bad end. For over 25 years, we’ve worked with compassion and creativity to show just that.
