Is your passion for making great infrastructure being kept in a box labeled “for later”? Do you enjoy working with smart people and do you want to make their developer experience great?<br/><br/> Zendar is looking for an experienced Infrastructure Engineer who understands engineering needs and can work with engineers to make their life easier and more productive. Our team is a testament of the ability to unite engineers of different backgrounds over a common vision.

For our monorepo that means revisiting our testing strategy and making sure we can get a high-quality signal on the state of our release branch in a short period of time. For our smaller repos, we need to set up the release processes from scratch.</li> <li>Having large datasets at three geographical sites results in different challenges and some synchronization between locations is inevitable. We are currently working with different NAS devices and localized cloud buckets but we are ready to upgrade our data management capabilities.</li> <l
