Founding Engineer (£100k-£120k + Equity) at Iridium Credit

Job Description

• 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.

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

• 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.
