We're changing the way that people buy cloud services in Canada. Why? To help CTO's accelerate IT, improve disaster recovery, and avoid the legal and performance issues of relying on US-based cloud companies. Based in downtown Toronto and with operations across Canada, we provide a secure, fast, and scalable way to host enterprise applications, big data, and Disaster Recovery as a Service (DRaaS).

The Challenge

Think On Inc. is forming a local infrastructure and operations team to build the underlying physical architecture for our Virtual Data Centre offerings. This exciting and brand new endeavor in the realm of Virtual Data Centre technology has its roots in traditional network, systems and datacenter design and operations. The ability to span the gap between the physical disciplines and the virtual delivery is paramount.

Our mantra of “keep it simple” underlines all we do in delivering our solutions to our customers and initially to how we build it.

We are looking for highly motivated individuals that will use their understanding of craftsmanship and best practices to build robust, maintainable, redundant infrastructure. As a cloud provider, nothing is set in stone; we want to continually evolve our platform and the way we work by learning from what we've done and taking those lessons forward.
