Mission of this role
As a Fullstack Integration Developer, you make sure that scanners, Zebra devices, the RFID gate and all related hardware work reliably and seamlessly with Geartracking and Rentman. You own and build the middleware that connects devices to our cloud APIs and apps, keeping things stable, fast and maintainable with minimal support overhead.
In this role you are the main technical point of contact for everything hardware-related. You work closely with the Rentman product and development teams, escalate blockers quickly and make sure knowledge is documented and never dependent on a single person.
