Software Engineer II - Backend
About The Position
We are seeking a Software Engineer II to join a new team building the next generation of back-end services, APIs and integrations in the finance tech organization. Initially this role will focus on the systems that move financial data between external platforms and our enterprise contracting system, integrating with existing APIs, message queues and SQL databases. You will help build configurable, reusable services that can be extended to new sources, systems and acquisitions through configuration rather than one-off, hard-coded integrations. You will also help standardize how data moves across our billing systems to allow for greater visibility into patterns, errors and optimizations across a payments flow of billions of dollars a year. This position is in Richmond, VA and has a work schedule of Monday through Thursday in office and Friday work from home.
