Software Engineer 2 or 3 - Infrastructure

This is a multi-level posting. Candidates may be considered for any of the posted levels, depending on their level of experience and depth of expertise.

Our team is building a modern hybrid cloud platform from the ground up to support the next generation of applications across the organization. The platform provides foundational infrastructure, container runtime environments, developer tooling, messaging systems, and observability capabilities required to run reliable and scalable applications.

This is a greenfield engineering opportunity. The team is defining how infrastructure is built and operated using code, APIs, and declarative systems, with reliability, observability, and repeatability built in from the start.

Our approach emphasizes:

• Linux-first systems design
• Kubernetes as a core abstraction layer
• Infrastructure-as-code and Git-based workflows
• Open observability standards (Prometheus, OpenTelemetry)
• Distributed, software-defined storage and networking

Engineers on this team help build and operate the foundational platforms that support modern workloads and internal technology services.

MidAmerican Energy Company, a Midwest utility, provides regulated electric and natural gas service to more than 1.6 million customers in Illinois, Iowa, Nebraska and South Dakota. The company owns and operates a portfolio of power-generating assets, approximately 61% of which is wind generation.

Bachelor''s degree in management information systems (MIS), computer science or related technical field or equivalent work experience. (Typically four years of related, progressive work experience would be needed for candidates applying for this position who do not possess a bachelor''s degree.)

A minimum of four years of experience in infrastructure engineering, platform engineering, site reliability engineering, or a related engineering role.

A minimum of five or more years of experience in infrastructure engineering, platform engineering, site reliability engineering, or a related engineering role for level 3.

Experience in one or more of the following areas:

• Linux systems and core infrastructure fundamentals
• Container platforms and orchestration technologies such as Kubernetes
• Infrastructure‑as‑code and declarative system design (e.g., Terraform, Git‑based workflows)
• Distributed systems concepts and large‑scale infrastructure environments
• Open‑source observability tools including Prometheus, Grafana, or OpenTelemetry
• Exposure to distributed storage systems (e.g., Ceph or similar technologies)
• Networking fundamentals in distributed or hybrid environments
• API‑driven infrastructure and automation systems
• Foundational infrastructure security practices, including identity and secrets management
• Hybrid infrastructure environments spanning on‑premises data centers and cloud platforms

This software engineer-infrastructure contributes to the design, implementation, and operation of foundational infrastructure systems that power the company's technology platform. This role supports compute, storage, networking, and container infrastructure used by enterprise applications, internal platforms, and hybrid cloud environments.

Software engineers at this level focus on building, operating, and improving infrastructure platforms using established patterns, automation, and infrastructure-as-code. They work collaboratively with platform and operations teams while continuing to build deep technical expertise in distributed systems and modern infrastructure practices.

Automation & Infrastructure as Code

• Develop and maintain infrastructure automation using Go, Python, or Java
• Implement infrastructure provisioning and configuration using infrastructure-as-code tools such as Terraform
• Contribute to standardized infrastructure deployment and lifecycle management practices
• Build tooling that reduces manual effort and improves operational reliability

Platform Integration

• Support infrastructure dependencies for container platforms and distributed systems
• Assist with deploying, upgrading, and maintaining Kubernetes clusters
• Operate infrastructure services such as virtualization platforms and storage systems
• Collaborate with platform engineering teams supporting CI/CD, messaging, observability, and developer platforms

Observability & Reliability

• Implement monitoring and observability using Prometheus, Grafana, and OpenTelemetry
• Participate in incident response and post-incident analysis
• Contribute to reliability improvements and operational maturity

Security & Access Management

• Apply infrastructure security best practices
• Support identity, access management, and secrets management systems
• Collaborate with security teams to ensure infrastructure resilience and compliance
