Servers, networks, containers, and cloud services — you build the platform that everything else runs on, and you're paged when it doesn't.
As a Senior Infrastructure Engineer, you design, build, and maintain the foundational technology platform — compute, networking, storage, and cloud services — that applications and services depend on. This includes server management, container orchestration, infrastructure-as-code, CI/CD pipelines, and monitoring systems. The senior title means you're making architectural decisions about the infrastructure platform, not just provisioning individual resources.
Your day blends building with maintaining. You might spend the morning writing Terraform modules to standardize cloud deployments, then investigate a latency issue affecting production services, then review a pull request for a Kubernetes configuration change, then plan a migration from one cloud region to another. You need deep Linux knowledge, cloud platform expertise (AWS, Azure, or GCP), and coding skills in Python or Go for automation.
The core tension is reliability versus velocity. Development teams want infrastructure changes fast; reliability requires careful change management. You're building platforms that allow developers to move quickly without compromising stability — and when those things conflict, you're the one making the judgment call.
