The Engineering Team employs some of the top engineering talent who are constantly working to improve processes, quality and techniques, with the goal of producing the highest quality software solutions in the industry. The lines between traditional QA and software engineering are blurred here, with quality being considered at all stages of development.

Our team is comprised of very talented and highly motivated individuals, who pride themselves on working smarter, not harder. We’re empowered to make local decisions, reducing the overhead of getting things done. We aim for operational excellence, having a Dev Ops culture and a “you build it, you run it” mentality. We favor a Lean approach to our product development, following agile workflows such as Scrum and Kanban depending on the directive of the team.
