Kalles Group; United States; On-site; USD 140,000 - 180,000; Full time

Job summary

Kalles Group is seeking a DevSecOps Engineer to join a fast-paced security engineering team. You will build and maintain infrastructure as code with Terraform, own CI/CD workflows in GitHub, and ensure robust security practices across edge platforms including CDN/WAF with Fastly exposure.

You will mentor offshore teammates and contribute to scalable, proactive operations. The role emphasizes hands-on engineering, ship-and-run responsibilities, and collaboration with senior engineers to modernize

Qualifications

• Bachelor’s degree in Computer Science, Information Technology, or a related discipline, or equivalent professional experience.
• 3 years of experience in DevSecOps, infrastructure engineering, or a security-adjacent engineering role.
• Hands-on experience with CI/CD pipelines — you have built, maintained, or actively contributed to them, not just managed teams that do.
• Working knowledge of Terraform — you have used it in a real environment; building from scratch is a plus but not required.
• Proficiency in GitHub — PR creation, review workflows, branching strategies, and collaborative development practices.
• Experience with one or more coding or query languages such as Python, JavaScript, PowerShell, Bash, or SQL.
• Security-aware development mindset with an understanding of separation of duties, secure coding practices, and how to avoid introducing vulnerabilities through infrastructure changes.
• Ability to work independently in a fast-paced, understaffed environment and get oriented quickly without heavy hand-holding.

Responsibilities

• Build, manage, and maintain infrastructure as code using Terraform across security and edge platforms.
• Own CI/CD pipeline work including PR creation, review, and approval processes in GitHub.
• Support the operational health of CDN and next-gen WAF platforms, with direct experience in or strong exposure to Fastly highly valued.
• Contribute to the security of the software development lifecycle by enforcing separation of duties, reducing vulnerability introduction through code, and following secure development practices.
• Collaborate with senior engineers and platform owners to support platform migrations and modernization initiatives.
• Help build operational documentation, runbooks, and processes as the team matures its operational model.
• Onboard and mentor offshore team members on platform standards and engineering practices.
• Use GitHub Copilot and other AI-assisted development tools as part of day-to-day engineering work.
