Job Description:

Our “Billing” team is in charge of making sure that publicly funded mental halth agencies get paid for the valuable work they do supporting youths and their families. As a Sr. .NET Engineer / Architect you will become a pivotal member of our “Billing” team maintaining the flow of money that feeds the free psychological and psychiatric services to those who need them.

You’ll be working with the team to both maintain, debug, and improve our full stack solution. This is a very hands on position where you’ll have the ability to learn the stack “through doing” as well as contribute to the overall direction of the software and decide how we can address tech debt while delivering constant value to our customers.

Our architects work alongside the rest of the team, and their expertise it’s seen by their constructive contributions, by how they work for the success of the team, by their positive insights and how they improve everything they touch. The more Sr. you are at Exym, and the more you’ll be expected to help and support team members and to work for the success of our customers. You will NOT be sitting in an ivory tower designing a pie in the sky. You’ll lead by example and show others what it means to have deep architectural insights that allow a better approach to how we work, improving the quality, speed, and ease of delivery every step of the way. At times that might mean some drastic changes to our stack, while many others it will be the result of small but constant improvements in a definite direction.
