Join Serco’s Finance Transformation and help build the engine of growth
Serco is transforming Finance to support its future growth, creating a UK-led Global Finance Services (GFS) Hub at the heart of the organisation. This hub is designed to be a true engine of growth - delivering accurate, timely and well-controlled financial information while driving standardisation, efficiency and continuous improvement across the business.
This is an exciting opportunity to join that transformation in a key leadership role, owning the end-to-end Record-to-Report (R2R) process for the UK Division and helping shape how Finance operates across a complex, contract-led organisation.
The role
As Reporting & Transformation Controller, you will play a pivotal role in delivering a consolidated reporting service to Business Unit Finance Directors, Finance Business Partners and operational stakeholders.
Aligned to a specific Business Unit, you will act as the key interlock between the horizontal Record-to-Report (R2R) processes within the GFS Hub and the vertical Business Unit view of financial performance - translating outputs into clear, accurate and insightful P&L, cashflow and balance sheet reporting.
This is a highly visible role, acting as a trusted partner and “face of the Hub” to the business. You will support Finance Directors in signing off month-end results with confidence, owning the integrity of outputs and challenging where necessary to ensure accuracy, consistency and control.
Beyond month-end, you will play a central role in driving transformation - identifying inefficiencies, improving processes and helping embed a best-in-class finance operating model across Serco’s UK business.
As part of this you’ll:
- Act as a strategic partner to Finance Directors and Business Partners, providing assurance over the accuracy of reported results
- Own the translation of R2R outputs into Business Unit-level reporting, including P&L, cashflow and balance sheet
- Lead month-end “calibration” and act as a gatekeeper for Finance Director sign-off
- Investigate complex accounting entries, operational drivers and material variances to ensure Trial Balance integrity
- Build strong cross-functional relationships with Finance, operational and senior stakeholders
- Identify process inefficiencies and drive continuous improvement initiatives across reporting and finance processes
- Act as the “voice of the customer” within the GFS Hub, influencing and shaping end-to-end process design
- Partner with Global Process Owners and Finance leadership to standardise and enhance reporting outputs
- Support the development of consistent, insight-driven reporting packs (e.g. BPR) and improved data accessibility
- Work closely with offshore resources to deliver efficient, scalable reporting solutions
What you’ll need to do the role:
You’ll be someone who:
- Is a qualified accountant (ACA, ACCA, ACMA or equivalent)
- Has strong experience delivering financial reporting and analysis in a complex environment
- Thrives in stakeholder-facing roles and is confident engaging with senior Finance and operational leaders
- Has a strong control mindset, with a clear view of best practice processes and governance
- Is naturally curious, with the ability to investigate, challenge and interpret financial and operational data
- Has a passion for continuous improvement and driving transformation
- Is comfortable working with ambiguity, incomplete data and evolving processes
- Can balance operational delivery with strategic improvement initiatives
Essential experience & skills:
- Proven experience delivering monthly reporting and insight to senior stakeholders
- Strong understanding of financial reporting, controls and R2R processes
- Experience working across complex, multi-contract or multi-entity environments
- Ability to identify inefficiencies and implement practical, scalable solutions
