Job summary

Siemens Energy is seeking a Network Automation Engineer to transform repetitive network tasks into software-driven workflows. You will build Infrastructure-as-Code modules, integrate a source of truth with controllers, and create automated validation processes to boost reliability.

You will collaborate with network architects, service owners, SRE, operations, and suppliers to streamline platforms, making them faster, safer, and easier to use.

Qualifications

• University degree in IT, CS, engineering, or equivalent practical experience.
• Solid enterprise networking knowledge: routing, switching, IP services, and data centers.
• Hands-on software and automation with Python, APIs, data structures, and automation frameworks such as Ansible, Terraform, Nornir, or comparable tools.
• Experience with enterprise version-control and configuration-management practices, CI/CD, declarative infrastructure workflows, automated testing, secrets management, code review, and traceable infrastructure changes.
• Knowledge of network data models and interfaces such as YANG, NETCONF, RESTCONF, gNMI, OpenConfig, and vendor APIs is desirable.

Responsibilities

• Build and maintain reusable automation for campus, WAN, Data Center, DDI, and Secure Access platforms using declarative data models, APIs, and Infrastructure-as-Code practices.
• Establish version-controlled engineering workflows that include peer review, automated testing, policy checks, change validation, rollback, and configuration-compliance controls.
• Integrate network source-of-truth, IPAM/DDI, ITSM, controllers, telemetry, and supplier workflows to enable end-to-end orchestration and ensure accurate operational context.
• Convert high-volume manual activities and runbooks into standardized self-service workflows, reducing lead time, configuration drift, and dependency on individual experts.
• Create the technical foundation for AI-assisted and agentic NetOps by exposing trusted data, safe actions, audit trails, and measurable automation outcomes.
• Collaborate effectively across traditional network operations, architecture, SRE, and supplier teams to drive innovation and efficiency.
