A day in the Platform Engineer role:

The Platform Engineer may design and build cloud foundations, develop infrastructure-as-code templates, improve CICD pipelines, and automate system provisioning and configuration. They will focus on creating reliable, reusable platform components that support secure application deployment, system operations, and compliance requirements.

The Platform Engineer will work closely with Operations teams to ensure platform services are resilient, observable, and aligned with frameworks such as CMMC and NIST 800-171. They will participate in design discussions, contribute to technical standards, and continuously improve platform reliability and developer experience. The role provides opportunities to work with modern cloud tooling, automation frameworks, and observability stacks, while growing into senior technical or architectural leadership roles.

Responsibilities:

Design, build, and maintain shared platform services that support secure and scalable infrastructure across client and internal environments.

Develop and maintain infrastructure-as-code (IaC) using tools such as Terraform, ARM/Bicep, or similar frameworks.

Build automation for system provisioning, configuration management, patching, and lifecycle operations.

Support and improve CICD pipelines, deployment workflows, and platform integrations.

Implement platform-level security controls, including identity integration, logging, monitoring, encryption, and segmentation.

Collaborate with Security Operations and Compliance teams to embed compliance and audit-readiness into platform designs.

Monitor platform health and reliability, supporting incident response, root cause analysis, and continuous improvement efforts.

Communicate platform designs, changes, and operational guidance clearly to internal teams and clients.

Contribute to platform documentation, standards, runbooks, and architectural diagrams.

Identify opportunities to reduce manual effort, improve consistency, and enhance developer and operator experience through automation.
