Fractional Head of Engineering Salary

£600-£700/day + Equity

Company Description

— an AI-native M&A advisory platform building a world-first matching engine for business sales.

Job Description

You will architect a novel algorithmic engine to match business sellers with buyers using dual conversational AI agents. As a fractional technical leader, you will audit existing no-code infrastructure, design a scalable scoring system, and draft technical specs for execution. This role combines high-level architecture with long-term strategic engineering management.

Why this role is remarkable

• Architect a world-first product applying conversational AI agents to the $50B+ M&A industry, turning relationship-driven brokering into an algorithmic science.
• High-impact fractional equity stake (1.2%) in a funded startup with a £2M+ pipeline and proven product‑market fit.
• Flexibility to lead high-level technical strategy and team building without the daily grind of full-time execution, while owning essential industry infrastructure.

What you will do

• Conduct a technical audit of current Supabase and Vapi integrations to define a production-ready roadmap and scalable data model.
• Design the proprietary matchmaking scoring algorithm that weights buyer‑seller signals to deliver surgical targeting and valuation uplifts.
• Create detailed technical specifications and a hiring scorecard to recruit and manage the mid-level engineering team through to exit.

The ideal candidate

• Proven experience building multi-agent conversational AI or voice systems (Vapi, Retell, Lang Graph) in production environments.
• Background designing complex two-sided matching engines or scoring systems for marketplaces, recruiting platforms, or financial services.
• Senior leadership experience at post‑seed / Series A startups with the ability to translate non-technical founder vision into robust engineering architecture.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin. You could land this role. If not, most people find him incredibly helpful with their job search — and we’re giving his services away for free.
