Job description

Interim Group FP&A Consultant | Tech Scale-Up | London

Harmonic is delighted to be working exclusively with a rapid-growth technology business that has scaled internationally and now runs a number of entities across several countries. The finance function is rebuilding its reporting off the back of a systems change.

The Role

This is a six month interim engagement with a likelihood of being extended. You will be reporting into the Group Finance Director and partner closely with the broader FP&A and finance function. You will own the reporting rebuild: working out what the business needs to see at both regional and consolidated level, designing it, and getting it built and signed off. The systems work is being led separately, so this is a finance-owned role rather than a programme role.

Key Responsibilities

• Lead the design of the group's reporting suite covering actuals, budgets, forecasts and ad hoc reporting requirements
• Define reporting requirements with central and regional finance teams and establish a single reporting standard across the group
• Build automated reporting within the new environment to reduce manual preparation and improve turnaround
• Rebuild existing spreadsheet reporting, including the consolidation logic, within the new systems
• Ensure consolidation outputs and management reporting reconcile at every reporting level
• Ensure a high level of testing across both the old and new reporting to confirm accuracy ahead of sign-off
• Document changes, reporting logic and data definitions effectively for future use
• Support issue resolution and continuous improvement once the reporting is live
• ACA, ACCA or CIMA qualified
• Has designed a group reporting suite from scratch, not only run one built by someone else
• Strong grasp of consolidation, intercompany and the planning cycle
• Advanced Excel, comfortable with large data sets and rebuilding models
• Led on a programme of change management previously (ERP/Systems etc)
• Power BI
• Worked with ERP e.g. NetSuite, D365 etc
• Multi-entity or international group experience

Day Rate: up to £650 per day (Outside IR35)

Location: London (hybrid pattern to be confirmed)

Contract: Six months, with scope to extend

Start Date: ASAP

At Harmonic, we are dedicated to fostering an inclusive and equitable workplace. We actively welcome applications from individuals of all backgrounds and assure you that every candidate will be thoughtfully considered for the roles we represent, without regard to race, religion, gender expression, disability, or sexual orientation.
