Overnight Remote Senior Software Developer Jobs in Tennessee

Overview

The Senior Development Engineer – Hands-On Data Integrations is a senior individual contributor role within the Data Services team, focused on the design, build, and day-to-day operation of production data integrations for nonprofit and mission-driven clients.

This role is deeply hands-on. The specialist spends the majority of their time writing code, configuring integrations, monitoring data flows, troubleshooting issues, and delivering working solutions. Client interaction is practical and delivery-oriented, with success measured by integration stability, accuracy, and supportability—not slide decks or abstract architecture.

This role requires a continuous, fluid transition between very technical work and speaking in plain language for non-IT client staff. The Specialist must be able to translate accounting end-user experiences into a viable technical solution design that addresses all the client’s pain points, and then translate that solution design back into plain language for the clients.

Client & Team Collaboration

• Work directly with non-profit clients to understand desired system functionality and design the appropriate solution to best meet their needs.
