Senior Software Engineer Charlotte, NC

Debt Book 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 Debt Book.

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.

We are looking for a Senior Software Engineer who can exist in a fullstack environment. You will need to balance working on projects with your team and working across teams to implement improvements platform wide. Engineers at Debt Book work on products in multiple stages of maturity: we are enhancing some products that have been in use for years, we are launching new products, and we have some products that are in a more greenfield state.

We are seeking a Senior Software Engineer to thrive within our Majestic Monolith of Ruby on Rails and React. You’ll strike a balance between driving impactful team initiatives and collaborating across the organization to enhance our entire platform. At Debt Book, our engineers touch the full lifecycle of product maturity—from refining established systems to architecting brand-new, greenfield solutions. 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 application is a Majestic Monolith built with Ruby on Rails, React, and PostgreSQL. Our app is hosted in AWS, and we use Git Lab for our CI/CD pipelines and deployments. We use feature flags to allow us to continually integrate our code.
• Our front-end is built with React, Type Script, and MUI React. We have an in-house library of accessible components documented in Story Book. These components are being used in new development, and we are in the process of updating existing pages to use them.
• Our back-end is a Ruby on Rails JSON API that communicates with a React SPA (single page application).
• All of our engineers work on the front-end, back-end and database. We have some engineers who are much more experienced in one, but we can all do some work in any part of the stack.
• We have a small dedicated infrastructure team, but our teams deploy and monitor their own code.
• Engineers collaborate closely with product managers, designers, and industry specialists to understand problems and design solutions. Engineers manage breaking down work into tickets and planning and managing projects.

• Participate in all stages of the SDLC: solution shaping, system design, ticket writing/breakdown, write full-stack code, review code, perform deployments, participate in monitoring, and gather data for reporting.
• Own the quality of your work. Write tests and work with your team to ensure everything works before merging and releasing.
• Work cross-functionally on your team to ensure work is scoped to deliver quickly and deliver the right functionality.
• Work collaboratively with other cross functional product-focused teams.

• 4+ years of related professional experience
• Experience with Ruby or React
• Some familiarity with front-end and back-end web development
• Ability to communicate complicated technical concepts well with teammates in all functions, including non-technical roles
