Backend Software Engineer (C/C++)

We are developing a high-performance Rate Calculation Engine SDK used by banks across the U.S. to compute complex financial fees in real time. While our codebase is lean, it powers a mission-critical product relied on by a growing number of banks nationwide.Every bank has unique business rules, fee structures, and configurations — and that’s where the complexity and challenge lie. Our SDK abstracts that complexity and delivers speed, reliability, and flexibility to financial institutions at scale.If you're passionate about low-level programming, math-heavy logic, and building clean, dependable systems for high-stakes environments, you’ll fit right in.
