OnSecurity
OnSecurity is a VCT-backed cybersecurity business — 63 people, headquartered in Bristol.
Finance today is the CFO plus outsourced support.
This is a build job, not a maintenance job. You'll own everything technical and operational below the CFO — building the group finance function at the same time as the group itself gets built — plus an ERP implementation over the next 6–12 months.
If you've built a finance function from scratch, integrated an acquisition as the finance owner, and want to do it again at real pace, this is that role.
What you'll own
- Close and group consolidation — intercompany, cross-charges, eliminations
- Statutory accounts, audit and the auditor relationship
- Corporation tax, VAT, R&D claims, payroll compliance
- The ERP — chart design, configuration, cutover, and ownership afterwards
- Revenue recognition across subscription and delivered-services revenue
- The control environment across a growing group
- Integration of each acquired business onto our ledger, chart and systems
- Outsourced providers — bookkeeping, payroll bureau, acquired-entity support
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
Not in scope: commercial analysis, M&A origination, board pack, investor reporting, cash collection. The CFO owns those — this role is the technical and operational engine underneath.
What we're looking for
- Qualified accountant — ACA or ACCA preferred
- Track record of building a finance function, not maintaining one — you've designed the close, written the controls, fixed what was broken
- Direct experience integrating an acquisition as the finance owner — taking an acquired ledger, mapping it to a new chart, bringing it into a group close
- Have run multi-entity consolidation yourself, including intercompany and eliminations
- Exposure to two or more entities, or two or more organisations, at FC level or one below
- Revenue recognition experience across both subscription and point-in-time delivery
- Led a system implementation end-to-end — selection through to cutover (any platform)
- Uses AI deliberately in finance workflows — and can show us what you've built, not just talk about it
- PE or VCT-backed business background

Where you'll fit best
You've likely been an FC, Head of Finance, or a strong number two at a PE- or VC-backed buy-and-build platform, roughly £10m–£40m revenue, in services or tech, with two or more acquisitions behind you. Small enough that you built the process rather than inherited a team.
We welcome applicants from cyber, IT and managed services, professional services, agencies, hybrid software-and-services, and TIC backgrounds — the pattern of building group finance through acquisition transfers well across all of them.
Why OnSecurity
We're at an inflection point — M&A strategy in motion, a real ERP decision ahead, and a finance function that needs someone to build it rather than run it as-is. You'll have direct exposure to the CFO and the wider leadership team, genuine ownership of the systems and processes you design, and a live, fast-moving buy-and-build story to build your career on.
