Platform Engineer (Cloud-Native AI/ML Systems Integration) Location: Dayton, OH (preferred) | Remote Eligible (CAC Access Required) Clearance: TS/SCI Preferred Build the Infrastructure That Makes AI Mission-Ready This is not a typical engineering role. As a Platform Engineer, you will design and operate the infrastructure that enables AI/ML systems to function in real-world mission environments. Your work will directly support Air Force / NASIC-aligned programs, where performance, security, and reliability are non-negotiable. You won’t just build platforms: you’ll bridge the gap between AI development and operational deployment, ensuring systems scale, integrate, and perform under real constraints. What You’ll Do - Architect and operate Kubernetes-based platforms supporting AI/ML workloads - Build and manage containerized environments (Docker, Helm, OCI) for scalable deployment - Design and optimize data pipelines for ingestion, transformation, and model lifecycle support - Integrate AI/ML services into secure, mission-critical systems - Develop Infrastructure as Code (Terraform, Ansible) for repeatable, compliant environments - Build and enhance CI/CD pipelines (GitLab, Jenkins, GitHub Actions) - Implement observability and monitoring (Prometheus, Grafana) to ensure system health and performance - Collaborate cross-functionally to translate complex requirements into deployable systems - Solve engineering challenges within classified and constrained environments What You Bring - Strong experience with Kubernetes and cloud-native platform engineering - Hands-on experience with containerization (Docker, Helm) - Experience supporting data pipelines or ML-enabled systems - Familiarity with Infrastructure as Code (Terraform, Ansible) - Experience with CI/CD and DevSecOps practices - Understanding of distributed systems and system integration - Ability to operate effectively in secure or regulated environments Why This Role Matters In many environments, AI stops at experimentation; in this role, you ensure it becomes operational capability. You will: - Enable AI/ML systems to move from development to deployment - Support mission-critical operations tied to national security - Work at the intersection of cloud-native engineering, DevSecOps, and AI infrastructure - Build systems where failure is not an option and performance is essential Your work directly impacts how advanced technology is applied in real-world scenarios.
