1759 - DevSecOps Engineer

Sigma Defense is seeking a DevSecOps Engineer to join our team in Rome, NY. The successful candidate will be a technically curious problem solver who enjoys automation and learning new systems. This person may not be the team's deepest expert in Kubernetes, Azure networking, Linux, Python, or software development. Instead, they should understand enough across these areas to follow a problem through the entire release process, collaborate effectively with specialists, and determine where an issue needs to be solved.

The ideal candidate can look at a failed deployment and move comfortably between GitLab CI, source code, Linux, Infrastructure as Code, Microsoft Azure infrastructure, networking, and application configuration until they understand what happened.

Equal Opportunity Employer/Veterans/Disabled: Sigma Defense Systems is an Equal Opportunity Employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, or protected veteran status and will not be discriminated against on the basis of disability.
