Job DescriptionJob Description

DomainTools is looking for a dynamic Senior Systems Engineer who is passionate about operational excellence in hybrid cloud and bare metal infrastructure, automation, and team-building. Come help us build the tools and processes to accelerate the management, 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 tend to be 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. This includes helping move traditional services into our Kubernetes-based hybrid cloud, writing automation to deploy to bare metal hosts and services, modernizing our monitoring and observability tools, and building tools and processes to empower our 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.
