CFO | Frontier AI Lab | Series A | London
Package: £275,000 - £350,000 + £150,000 bonus + meaningful equity.
Harmonic are delighted to lead the search for a London-based frontier AI lab that have raised one the largest Series A rounds in UK history.
The Role:
First senior finance hire, reporting to the co-founders. This is a commercial and strategic role, not a reporting one. The company sells something technically complex and capital-intensive, with novel unit economics, and the CFO will be the person who turns that into a financial model, a pricing strategy, and a set of deal structures that actually work. This is the seat if you want to sit at the centre of the business rather than behind it.
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.
Core Initial Focus:
- The financial model the company runs on, built from scratch to reflect a business that does not fit standard templates.
- Product and pricing economics, including the commercial strategy for how the company charges for what it delivers.
- Financial structuring of significant capital commitments as the business scales its infrastructure.

Who This Is:
A commercial finance leader who has built, not inherited, in a high-growth environment.
- You will have operated in a capital-intensive or infrastructure-heavy technology business.
- Compute, Semiconductor, Defence, Energy & Telecoms backgrounds are all relevant. What we are looking for above all is someone with the credibility and communication skills to be a genuine partner to a highly technical founding team.
Package: £275,000 - £350,000 + £150,000 bonus + meaningful equity.
