Iridium Credit is a London-based fintech, backed by a multi-million-dollar seed round from top US VCs and Entrepreneurs First, automating the $7 trillion US invoice financing market. Founded by veterans from Morgan Stanley and Microsoft, the company builds AI agents that verify invoices for bank-owned lenders processing $100M+ monthly.

As the first founding engineer at Iridium Credit, you will build and own production AI agents across browser, voice, and email. Working directly with founders from Morgan Stanley and Microsoft, you'll solve complex verification challenges for bank-owned lenders, architecting reliable systems that process hundreds of millions in monthly invoice value for small businesses.

Location: London, UK

Why this role is remarkable:

  • Work on a $7 trillion problem building "self-healing" AI agents and voice systems that navigate complex B2B dialpads and portals for bank-owned lenders.
  • Backed by a multi-million-dollar seed round from two major US VCs and Entrepreneurs First, with live contracts already processing $100M+ in monthly volume.
  • Transition with the company from London to New York in the coming months, with full US visa sponsorship and relocation costs covered by the company.

What You Will Do:

  • Design and deploy sub-agent architectures that handle browser automation, CAPTCHAs, 2FA, and real-time voice interactions with accounts payable teams using Python.
  • Own features end-to-end as employee number four, making critical architectural decisions across the backend, frontend, and infrastructure to ensure bank-grade system reliability.
  • Collaborate directly with lenders and founders to understand commercial context and bridge the gap between technical builds and complex banking compliance requirements.

The ideal candidate:

  • Strong engineering generalist with deep Python experience and a track record of building reliable systems that work against the messiness of the real-world web.
  • Experience with browser automation (Playwright/Puppeteer), AI agents, or production ML, particularly systems requiring high reliability when operating within changing external environments.
  • High-growth mindset with the appetite for early-stage startup intensity, ready to step into an engineering lead role within the next twelve months as the team expands.
