Developer

About the Role

As our new Developer, you'll work with our close-knit Agile team to support and implement changes to our billing software. This is a full lifecycle development role, not a reporting, ETL, or database administration position. You'll work primarily in SQL Server (the majority of the role), with APIs and application-level components (C#/.NET) rounding it out. The ability to reverse-engineer and confidently modify existing code is central to the role. In addition to maintenance and support tasks for the client, you'll be involved in all aspects of Agile software development including planning, designing, building, testing, releasing, and feedback.
