Financial Modeller
Oxford
6 Months Fixed Term Contract
Competitive salary + strong benefits package
Hydrogen · Clean energy · Infrastructure
THE CONTEXT
The UK's hydrogen infrastructure is being built right now. Hydra B is at the centre of it, developing the technology, vehicles, power systems and services that will move green hydrogen from ambition to operational reality across the transport and energy sectors.
The numbers that underpin those decisions - investment cases, project economics, scenario planning, lender analysis - need to be right.
That's this role.
THE ROLE
You'll build, maintain and run financial models across HydraB's projects and business units. Three-statement models, cash flow analysis, scenario and sensitivity work, and the supporting schedules that serious finance decisions are made from.
You'll work directly with the Head of Finance and Group CFO, and partner with engineers, commercial leads and operations teams to make sure the numbers reflect what's actually happening on the ground.
High volume. High accuracy. Fast turnaround. The kind of role where the work genuinely matters.
WHAT WE'RE LOOKING FOR
- Advanced Excel craft — structured, documented, auditable workbooks that finance leaders can trust and others can pick up
- Working Python — pandas, openpyxl or equivalent for data wrangling, automation and repeatable outputs
- 3–5 years in a modelling role — corporate finance, project finance, infrastructure, banking, FP&A or similar
- Obsessive accuracy — reconciles to the last penny, never sends a model with a hardcoded plug
- Comfortable holding multiple model requests in flight while partnering with senior stakeholders
BACKGROUND - WE'RE OPEN
A formal finance qualification is not required. We're equally interested in candidates from engineering, mathematics, physics or computer science who have built serious modelling craft.
What counts is the quality of the work.
NICE TO HAVE
- Infrastructure or project finance modelling experience
- Energy, hydrogen or transport sector exposure
- Lender or investor-ready model delivery
- Experience building model standards or libraries across a finance function
WHAT WE OFFER
- Salary — competitive, benchmarked to the role and your experience
- Pension — up to 8% employer contribution (via NEST)
- Holiday — 25 days plus bank holidays, with buy and sell flexibility
- Life assurance — 4x basic salary

- Private medical and dental — (BUPA), with option to add dependents
- Salary sacrifice electric car scheme

- Critical illness cover
- Employee Assistance Programme — 24/7, 365 days
- Employee referral bonus
