Cloud Reliability Engineer (Platform Infrastructure)

The Opportunity:

We're looking for a Cloud Reliability Engineer to drive the design, build, and support of cloud-native infrastructure and platform services for critical Department of Defense mission systems. This isn't just about operations; it's about owning the reliability of the product, directly impacting user outcomes. You'll define, measure, and enhance reliability using frameworks like Critical User Journeys (CUJs), collaborating with product stakeholders, DevSecOps, and cybersecurity teams.

We have career opportunities spanning four collaborative teams:

• Collaboration Services

• Infrastructure as a Service

• Mission Applications

• DevSecOps (Development, Security, and Operations)

Job Responsibilities:

• Engineer Cloud-Native Platforms: Design, deploy, and maintain robust Kubernetes clusters and supporting services across AWS GovCloud and Azure.

• Drive User-Centric Reliability: Collaborate to understand Critical User Journeys (CUJs). Define and implement product-level Service Level Objectives (SLOs), focusing on user-visible behaviors and outcomes (availability, latency, etc.).

• Automate Everything: Provision, configure, and monitor platforms using Infrastructure-as-Code (Terraform, CloudFormation).

• Enhance Observability: Implement and leverage telemetry and request-level annotation to directly link infrastructure requests to product functionality and mission partner objectives.

• Secure & Comply: Manage identity, access, patching, logging, and backups in multi-tenant environments, integrating RMF, Zero Trust, and IL5+ hardening into platform design.

• Troubleshoot with Impact: Prioritize and resolve platform service and infrastructure issues based on user impact and product criticality.

• Collaborate & Document: Work within Agile teams, contribute to user objective refinement, and maintain comprehensive system documentation.

Qualifications:

Required:

• Active TS/SCI Clearance.

• Bachelor’s degree in a technical field with 3+ years of relevant experience.

• Deep expertise with AWS (GovCloud/SC2S), Kubernetes (EKS or self-managed), Linux, and CI/CD tools.

• Proficiency in Bash or Python.

• Hands-on experience with Git/GitLab, container registries, and infrastructure monitoring.

• Strong understanding of cloud security, IAM, networking, and platform lifecycle management.

• Proven ability to translate user needs into measurable reliability targets and implement user-focused SLOs.

• Excellent communication and troubleshooting skills, with a focus on end-user experience and product reliability.

• Solid grasp of cloud networking, load balancing, and DNS.

• Certifications: CompTIA Cloud+ or Security+; GICSP, SSCP, or GSEC.

Desired:

• Master’s degree in a technical discipline.

• Experience with Air Force or DoD platform infrastructure environments (e.g., Platform One, Iron Bank, Big Bang).

• Familiarity with Atlassian tools and DevSecOps workflows.
