Reports To: Chief Technology Officer

About Position

This is a full-time back-end developer role, reporting to our Chief Technical Officer (CTO) and supporting Useful Group’s development services.

The back-end developer will work closely with the CTO and development team across multiple projects and clients with an emphasis on strategic problem solving and back-end development activity. The CTO is currently performing the majority of back-end development and is looking for a candidate who can support and own back-end development tasks for an ongoing pipeline of projects. This will enhance the current project flow and reduce the chance of bottlenecking new project activity.

While some repetitive tasks are part of this position, week-to-week tasks may vary based on Useful Group’s needs. The most important responsibility of the back-end developer is to ensure back-end development tasks are completed efficiently and effectively.
