Job description

As a developer for Loek! you are expected to be pro-active, working directly with the Product & Delivery Manager in the Netherlands. You will maintain the existing software (all .NET/Azure related) and develop new features that will wow our customers. As you will be one of two developers working from the Plovdiv office in a startup like environment, we really need you to be experienced and confident in your coding skills to work independently and professionally.

What does this software do exactly?

Loek’s software ensures that the owner, manager and tenants of a building keep in touch on the exact status of the state of the building, i.e. all maintenance that needs to be done and that’s been carried out. Through a smart system of QR codes that are put on all devices (e.g. the elevator, a washing machine, lamps etcetera), every tenant can scan a broken machine and upload in the the app where it automatically becomes a ticket. In the same fashion, the real estate manager can use the app to make a service request to a supplier. These tickets and requests are then uploaded and the metda data tracked in the Blockchain so every stakeholder knows exactly its status. The same goes for lease contracts; everything is tracked through Blockchain so no need to send and follow up emails anymore ?
