We are a dynamic and rapidly growing software company with a strong sense of dedication to our customers and the Chef community. We work hard but try not to take ourselves too seriously. This is a very collaborative and inclusive work environment. Individuals, strong on aptitude and attitude, will have an opportunity to grow their professional careers through working with some of the most advanced technology and talented developers in the business. We provide competitive compensation, generous benefits, and a professional yet relaxed atmosphere.

Application automation (Chef Habitat) is one of the three pillars of Chef technologies, in addition to Infrastructure Automation and Security and Compliance Automation. Chef Habitat enables IT Operators to codify how an application is built, how it runs, and all of its dependencies to free the application from underlying infrastructure and make updates easy. It enables the same application, along with all its dependencies to be defined once and packaged to run in various environments including on various Operating Systems, cloud environments and containers.

Chef Habitat allows you to package, deploy, and run your application in an infrastructure agnostic way. Chef Habitat enables applications to run in containers, in virtual machines, and on bare metal hosts. As a member of the Habitat team you'll be working on our Supervisor and/or Builder components. Supervisor is an agent that manages Habitat enabled services and shares configuration data with other Supervisors on other machines. Builder is the artifact repository, user facing API, CI build service, and web front end for Habitat packages. Both of these services are written in Rust. We also make extensive use of Bash and Powershell shell scripts for creating Habitat plans and building our packages.
