Fractional Head of Engineering / AI Architect at Foundy - AI-native M&A advisory platform

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.

• 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.

• Proven experience building multi-agent conversational AI or voice systems (Vapi, Retell, LangGraph) 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.

• 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.
