Over time, the successful candidate will become the in-house expert on the VersaCall platform, serving as the go-to resource for both clients and internal teams. This role has two sides: client-facing technical support and hands-on software development. The expectation is not to build new features independently from day one -- our stack is complex and has many moving parts. We value someone who is eager to learn how our technologies fit together, get comfortable with the codebase, and gradually take on debugging, enhancements, and eventually new feature development.
