Responsibilities
Design and build internal platform capabilities that support application development, deployment, and operations
Establish and implement enterprise technical standards and architecture patterns for infrastructure, platforms, and development environments
Develop and maintain DevSecOps platforms and CI/CD pipelines that support secure and automated software delivery
Design and operate cloud and hybrid infrastructure environments across AWS, Azure, on-premises, or edge environments
Engineer and manage compute, storage, and virtualization platforms supporting scalable workloads
Design and maintain secure network architectures and connectivity, including segmentation, zero trust approaches, and hybrid networking
Build and operate infrastructure as code (IaC) capabilities to standardize environment provisioning and configuration
Implement security boundaries, platform hardening, and baseline configurations aligned with enterprise security requirements
Support endpoint and collaboration platforms that enable secure productivity and engineering workflows
Manage infrastructure lifecycle operations including provisioning, upgrades, patching, and capacity planning
Collaborate with security, architecture, and product engineering teams to ensure platforms support secure, compliant, and reliable application delivery
Improve platform reliability through monitoring, automation, and operational tooling
Qualifications
Strong experience designing and operating modern infrastructure and platform environments
Experience building and maintaining DevOps or DevSecOps platforms and CI/CD pipelines
Proficiency with cloud platforms (AWS, Azure, or GCP) and hybrid infrastructure architectures
Experience with infrastructure as code using tools such as Terraform, CloudFormation, Pulumi, or similar frameworks
Experience working with containerization and orchestration platforms such as Docker and Kubernetes
Strong understanding of networking fundamentals, including routing, segmentation, and secure connectivity
Experience managing compute, storage, virtualization, and infrastructure services
Familiarity with automation, configuration management, and platform observability tools
Strong engineering fundamentals including version control, automation, and operational reliability
Preferred Qualifications
Experience designing internal developer platforms or platform engineering capabilities
Familiarity with enterprise architecture frameworks and technical standardization
Experience implementing DevSecOps practices including automated security scanning and policy enforcement
Knowledge of zero trust networking, identity-aware infrastructure, and secure platform architectures
Experience supporting regulated or security-sensitive environments
Experience with infrastructure monitoring, logging, and observability platforms
Familiarity with endpoint management and collaboration platforms
Experience working in cloud-native and hybrid enterprise environments
What Success Looks Like
Engineering teams can provision environments and deploy applications quickly using standardized platforms
Infrastructure is automated, reproducible, and managed through code
Platforms provide secure, reliable, and scalable foundations for mission applications
Enterprise technical standards are consistently implemented across environments
Infrastructure operations are highly automated and operationally efficient
Platform capabilities improve developer productivity and delivery velocity
Why This Role Matters
Modern organizations depend on platforms that enable engineering teams to move quickly without sacrificing security or reliability. The Platform Engineer builds and operates these foundational
capabilities—turning complex infrastructure into reusable, automated platform services that support secure and scalable software delivery.
By standardizing infrastructure, automating operations, and enabling self-service environments, this role helps ensure that development teams can focus on building mission capability rather than managing infrastructure complexity.
