AI Engineer
London | Hybrid (3 days onsite)
£80,000 - £120,000 + meaningful equity
We’re partnering with an early-stage AI company building an agentic AI platform designed to transform how teams within financial services operate.
This is a rare opportunity to join as a Founding AI Engineer, working at the core of the product and playing a key role in shaping both the technology and the engineering culture from day one.
The OpportunityYou’ll be building production-grade AI agents that automate complex, mission-critical workflows across client-facing and operational teams. These agents integrate with existing systems, pull from internal and external data sources, and execute real work on behalf of users - with optional human-in-the-loop control.
The platform is already live with paying customers, generating meaningful revenue, and has a long-term roadmap focused on scale, depth, and impact.
This is not an R&D sandbox - this is real AI, in production, solving real problems.

Why This Role?- Founding-level impact - your work will directly shape the platform
- Modern AI stack - building at the cutting edge, not maintaining legacy systems
- Strong equity upside alongside a competitive salary
- Hybrid London setup with a collaborative, high-calibre team
- A product already in market, with traction, revenue, and momentum
- £80,000 - £120,000 base salary
