What about Qatium’s challenges?

We have no choice but to innovate

Qatium is competing face to face against heavy desktop applications, but as a web application.

In order to succeed, we have to use the resources provided by the browser to their full potential. You will use technologies such as Mapbox and you will have to care about your code’s efficiency. Also, most of the app’s logic runs in the browser: there is no backend.

We’re building a completely new product, building the tools and frameworks that make Qatium possible.

We apply high quality engineering

Qatium is not a simple CRUD. You will face complex problems related to hydraulic simulation, handling GIS data and real-time graphical representation among others. Qatium is able to ingest and transform data from hundreds of sensors in real time.

Qatium needs to convey a lot of information simultaneously

We are building a single software package for users with different expertise levels inside the water industry. All of this, built over an interactive map. We learn from our users to provide them with the information they find more useful at every moment in time.

We are continuously discovering our path

Being a new product, our future is yet to be built. We have the responsibility of transforming our product vision into software that is useful for our users, relying on their feedback.

We participate in the whole product cycle

We are organized as a single autonomous product team, including people with different backgrounds and expertise levels.
