About our Central Technology team

At Xplor, we have many different products and technologies. We have evolved from a bunch of start-ups to a single company with over 700 Xplorers who work in our CT team as one team across the world. You can find everything from super modern to older languages. We continue to iterate on our processes and technologies to find common ground between the different projects and product we have.

With this, we rely heavily on our engineers to be dynamic. Xplor is not the company (yet) where you’ll always have well-defined requirements and rigid processes. Our Engineers have a lot of input into the process and requirements. However, there can be challenges and ambiguity you as an Engineer have to overcome – and we know that’s not for everyone. The positive side of this is that you get to have a lot of say and ownership in the product and the process.
