Senior Software Engineer

### WHO WE ARE

DebtBook is the financial platform powering treasury and capital markets across the public sector. State and local governments, public universities, health systems, and the bankers and advisors who serve them run trillions of dollars in debt, cash, and investments on DebtBook.

We've built the most sophisticated treasury platform in public finance — sitting at the intersection of treasury management and a $4 trillion fixed income market that's been waiting for modern infrastructure.

As a senior member of the team, you will act as a bridge between various practice areas, providing mentorship to colleagues while leading efforts in system design, solution shaping, and decomposing complex epics into actionable tasks.

• Our front-end is built with React, TypeScript, and MUI React. We have an in-house library of acces
