Senior Systems Engineer

DomainTools is looking for a dynamic Senior Systems Engineer with a passion for making the right operational improvements in a collaborative team environment. Come help us build the tools and processes to accelerate the operation and delivery of our security products. We build on open source technologies and operate services in both public- and private-cloud environments to serve a customer base that includes 45% of the Fortune 100. 

Our senior engineers are deeply curious open source enthusiasts, veteran generalists who are eager to solve infrastructure problems at all levels of the stack. We are focused on projects that will help us operate faster, more reliably, and scale into the future. We are aggressively moving older services into our kubernetes-based hybrid cloud, re-writing the deploy automation for our bare metal services, improving our observability story, and looking for ways to better serve our many internal customers.

We’re a small enough company that we get to collaborate with most of the engineering teams in the organization. That means learning alongside a lot of smart people, and touching a technology stack that is broad and diverse. It’s an opportunity to have fun learning with a great team and make a big impact.
