Junior Fullstack Developer

Invitation Project is creating an app that helps Christians invite their close friends to discover & follow Jesus. Many Christians long to see someone in their life - a cousin, roommate, coworker - discover Jesus, but don't know how to start, or what to say.

We equip believers to invest intentionally in friendships with up to five people they already know, helping them discover Jesus. Everything we create is grounded in Scripture, shaped by grace, and built to honour the pace of every journey.
