Senior FullStack Engineer

Kanmon | Senior FullStack Engineer | Hybrid (San Mateo) or REMOTE Kanmon is built around B2B finance and it's one of the largest and most broken markets in the world. SMBs are 44% of US GDP and extend over $5 trillion in trade credit to each other every year yet modern financial infrastructure intermediates less than 10% of it. The rest still runs on PDFs, paper invoices, and underwriting cycles measured in months. Kanmon is rebuilding that stack from scratch. We're the finance infrastructure that lets software platforms embed payments and working capital directly into the software their SMB customers already run their businesses on. Kanmon has raised new capital to go a layer deeper and are building an AI cashflow and business credit copilot that helps businesses make smarter financial decisions in real time. It's a genuinely new category of product, and we're architecting it from zero. We're hiring a senior full-stack engineer to own it. End-to-end ownership, direct line to founders, no PM handoffs. Full stack TypeScript: React, Next.js, NestJS, PostgreSQL, GCP. Competitive comp | mags@kanmonhq.com
