Job Summary
Were looking for a Senior Fullstack Engineer (React Node) to join our partners startup.

About the Client
The client is building modern financial infrastructure to accelerate the growth of American industry starting with a fundamental problem: equipment financing.
In the U.S. most industrial businesses dont buy machinery upfront they finance it. This $1.3T market powers sectors like manufacturing logistics and agriculture but still runs on outdated systems. Third-party lenders dominate offering loans at 40% APR relying on manual approvals and paper-heavy processes and accounting for over $1T in annual financed sales.
A few major manufacturers have solved this by creating their own finance divisions but 99.5% of equipment vendors cant afford to. The client enables them to do just that providing AI-driven underwriting capital-as-a-service point-of-sale integrations and a complete suite of software and financial tools.
Their partners range from robotics startups and family-owned equipment dealers to medical suppliers and heavy machinery OEMs. Wherever equipment is sold their vision is to become the financial operating system powering the transaction.
This is a deeply complex challenge and it demands an exceptional team. The company brings together experts from industrial operations fintech and capital markets who have built platforms used by millions scaled finance funds beyond $100M in revenue and raised billions in capital facilities. Backed by a $7M seed round from leading investors theyre now executing on that vision.
Theyre looking for people who think long-term move fast and care deeply about rebuilding Americas industrial strength. If that sounds like you theyd love to meet you.
