The Role

We are hiring a Software Engineer (B2B Lending & Payments) to take ownership of the financial infrastructure that powers how our clients finance their assets through INFINIT.

We believe the most resilient lending and payment systems are built by engineers who operate at the intersection of deep technical mastery, genuine product judgment, and direct proximity to the client’s financing workflow. This is not a ticket-execution role. You will work with business stakeholders and clients to understand why a problem matters before deciding what to build then use agentic coding to ship the how fast and well.

Partnering with other engineers owning this domain, you will own two deeply connected responsibilities. First, crafting the best possible experience for a client going through a loan application, from the moment they submit a request to the moment financing is confirmed, every step should feel clear, fast, and trustworthy. Second, ensuring that every payment executed throughout the loan lifecycle (interest accruals, supplier disbursements, reimbursement) is processed correctly, securely, and without exception. Third, supporting the physical audit and due diligence workflows that allow us to maintain control over the collateral throughout the life of the loan.

You will be the person the rest of the team pings when something in this domain breaks.
