About the Role
Most finance roles leave you buried in month-end while someone else makes the decisions that matter. This one doesn’t.
You’ll take full ownership of the Cambridge site’s finances at a company that has just gone from independent UK biotech to part of a major global organisation. Lex Diagnostics builds ultra-fast cartridge-based PCR systems that deliver results in minutes, not hours. The technology is already changing how clinics work. Now the finance function needs to keep pace as we scale manufacturing, commercialise the first products, and integrate with a much larger parent company.
What You’ll Actually Do
- Run the day-to-day financial management of the site — accounts payable and receivable, general ledger, cash, and a controlled month-end.
- Own the weekly cash flow forecast so leadership always knows where we stand.
- Lead the quarterly forecasting and annual budgeting cycles, challenge the numbers that come in, and turn them into plans people can actually use.
- Prepare the monthly management packs that go in front of the site CEO and senior team.
- Be the main point of contact for the external auditors and tax advisors (including Research and Development Expenditure Credit RDEC).
- Keep the balance sheet clean and the controls tight.
- Spend a lot of time talking to operational leaders and colleagues in global finance, treasury, shared services, corporate accounting, so the numbers support real decisions rather than just reporting them after the fact.
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.
This is a hands-on role. You’ll still get your hands dirty in the detail, but the real value is in the insight and the partnership.
Who This Will Suit
- A fully qualified accountant (ACA, ACCA, CIMA or equivalent) who has already run financial management, reporting, and business partnering in a fast-moving environment.
- Knows your way around month-end, statutory accounts, budgeting, and forecasting.
- Comfortable with IFRS or UK GAAP and understands how proper controls actually protect a growing business.
- Good with numbers and better with people.
- Can sit with an operational manager and help them see the financial consequences of their choices without making them feel stupid.
- Can prioritise when everything feels urgent.
