About The Position

Caliola is a woman-owned small business that is improving and protecting our Nation's way of life through secure collaboration and resilient communications. Our engineers, subject matter experts, and veterans are developing and delivering trusted solutions for mission-critical communications. We seek teammates who share our core values: I3 for C3 - Insight, Innovation, and Integrity for Command, Control, and Communications. These values guide how we work every day. At Caliola, you will find technically challenging, mission-focused work within a flexible and collaborative culture that is uncommon in the defense industry. We offer flexible PTO, subsidized health insurance, 401(k) matching, professional development, and a competitive compensation structure designed to support long-term growth. Our performance has driven rapid growth and national recognition, being named twice to the Deloitte Technology Fast 500™ and inclusion on the 2025 Inc. 5000 list of America's fastest-growing private companies. We have also been recognized as a Colorado Company to Watch, a ColoradoBiz Top Company in Aerospace & Defense, and the #2 Gazette's Best Workplace (medium size) in 2025. Headquartered in Colorado Springs, CO, we operate in a leading aerospace and defense hub with proximity to major military installations. Set against the Rocky Mountains, the region offers year-round outdoor recreation and a high quality of life for professionals and families considering relocation. The DevOps / Platform Engineer will be responsible for ensuring Caliola's on-premises and cloud infrastructure is operational, maintained, backed up, hardened, and aligned with program and security requirements. This role sits within Caliola's IT & Cybersecurity team and supports engineering teams working across unclassified and secured environments where infrastructure, tooling, build workflows, scanning, configuration, and documentation are often customized to meet specific customer, accreditation, and mission requirements. This is not a traditional commercial DevOps role focused primarily on large-scale automated deployment pipelines. Caliola's environments are complex because of security requirements, program-specific configurations, controlled development workflows, legacy software constraints, accreditation needs, and classified operations. This individual will resolve infrastructure issues through Caliola's ticketing system, communicate regularly with engineering teams to understand their needs, and help develop, deploy, and maintain compliant solutions, tools, and initiatives in support of Caliola's development environments.
