Founding Engineer at Proximitty

As the first founding engineer, you will build autonomous lending agents for major US banks. You'll solve frontier AI challenges including long-horizon reasoning over financial data and self-evolving agent architectures. This high-impact role involves owning the product end-to-end, from core infrastructure to deploying live systems alongside credit officers at leading financial institutions.

• Architect and build the core infrastructure for autonomous lending agents capable of document ingestion and financial spreading.
• Deploy products live at customer sites, flying to banks to iterate in real-time based on direct feedback from credit officers.
• Develop a software factory and self-evolving agent systems that automatically improve through automated hill-climbing on evals.

• Expert-level TypeScript and AWS skills with a deep understanding of distributed systems and frontier agentic architectures.
• Proven ability to ship reliable AI agents for regulated industries like fintech or banking where security and auditability are paramount.
• Founding-engineer mindset: you are a product-focused builder who thrives on talking to customers, shipping fast, and owning outcomes end-to-end.

• Join a YC W26 startup with high-pedigree founders from McKinsey and Bloomberg who are already hitting 7-figure ARR milestones.
• Backed by elite investors including CRV, Y Combinator, and Uphonest, alongside strategic angels from Stripe and OpenAI.
• Direct ownership of frontier agentic infrastructure, including self-healing agents and large-scale evals for a $3+ trillion commercial credit market.
