You are a technically curious Backend Developer who loves the Devops side too and wants to be part of a core development product team. You have flirted with Devops scope before, love automation and definitely have an opinion on systems architecture?
You do understand (and maybe even have already harvested) the power of things like TDD, DDD, CQRS, AWS, Ansible, Terraform ?

Then apply for the position of Senior Backend Developer at VONQ and be part of our team that builds our flagship product, tools and APIs that serve global customers! #gettingthingsdoneright.
