Senior Finance Manager - 12-Month Maternity Cover
We’re looking for an experienced Senior Finance Manager to join Ryze Power in Oxford on a 12-month maternity cover, owning month‑end, VAT, audit and cash forecasting for HydraB’s energy transition business. If you’ve seen it before, take pride in a clean balance sheet and are happy to take ownership and run with it, this one’s for you.
THE CONTEXT
The UK’s fleets are going zero-emission, and they need the energy to get there. Ryze Power provides it - supplying hydrogen, building EV charging infrastructure and delivering energy services for commercial fleet, industrial and public sector customers across the UK.
From hydrogen bought and sold to infrastructure projects delivered on the ground, Ryze is where the transition to zero-emission transport becomes real. As part of HydraB Group, alongside businesses building the vehicles and hydrogen infrastructure behind that shift, Ryze brings it all together for the customer.
Finance that keeps pace with that, with no surprises. This role owns that.
THE ROLE
This is a hands‑on, individual contributor role covering Ryze Power’s full reporting cycle - month‑end close, balance sheet reconciliations, quarterly VAT, audit and cash flow forecasting.
Reporting to the Finance Director, you’ll own Ryze Power’s results and sub‑ledgers in Sage Intacct, while Group Finance manages consolidation and treasury. You’ll work closely with Ryze’s operations and sales teams, Group Finance and Legal.
Support is there when you need it, but this role needs someone who can pick things up quickly and run with it from day one. It’s a full‑time role, based fully on‑site in Oxford, 5 days a week.
WHAT YOU’LL ACTUALLY DO
- Lead the monthly, quarterly and annual reporting cycle, producing accurate and timely management accounts
- Own month‑end close and balance sheet reconciliations, keeping the control environment strong
- Prepare quarterly VAT returns and manage other statutory and tax filings
- Coordinate the external audit - auditor queries and year‑end financial statements
- Manage cash flow forecasting and liquidity planning, working with Group Finance on treasury
- Get to grips with the commercials of the business - stock, fixed assets, project costs and revenue, and hydrogen bought and sold
- Keep Ryze Power’s sub‑ledgers and intercompany balances accurate and reconciled ahead of Group consolidation
- Oversee invoicing, collections, credit control and supplier payments to keep working capital under control
- Ensure compliance with FRS 102, the Companies Act and Group accounting policies, including fixed asset accounting and capitalisation
- Spot and deliver improvements to finance processes, controls and reporting
YOU’LL BE A GREAT FIT IF YOU
- Are ACA, ACCA or CIMA qualified with 5+ years’ post‑qualification experience, including time as a Finance Manager or similar
- Have owned month‑end close, balance sheet reconciliations, VAT and audit hands‑on
- Know UK GAAP and FRS 102 well, and have worked in a group structure with intercompany and consolidation reporting
- Have experience in a growing SME, engineering, manufacturing or project‑based environment
- Have advanced Excel skills and a high level of accuracy
- Are a natural problem solver who picks things up quickly and can run with it without close supervision
- Are proactive and keep people in the loop - no surprises
- Build good relationships with finance and non‑finance colleagues, and can explain the numbers clearly
NICHE TO HAVE
- Sage Intacct experience, or a similar cloud ERP
- Experience in energy, hydrogen or infrastructure project accounting
