Senior Cloud & Infrastructure Engineer - Project Delivery & Implementation (m/f/d)

Shape the utilities market of the future with us!

Permanent / Full-time / Leipzig, Erfurt or Ilmenau (hybrid) – remote within Germany possible / Start ASAP

Cuculus is looking for a hands-on senior engineer to design, build, implement and manage secure, scalable and cost-effective cloud and infrastructure environments for customer projects across cloud, on-premises and hybrid platforms.

What is the role about?

Own customer environment delivery from approved architecture through cloud provisioning, Infrastructure as Code, OpenShift/Kubernetes implementation, migration, production readiness, optimization and handover. This is not a routine Production Support role; the engineer will assist with critical customer issues requiring specialist expertise.

Your Role at a Glance

Cloud infrastructure and services

• Design, deploy and manage cloud infrastructure and services across AWS, Azure or equivalent platforms, including on-premises and hybrid integrations.
• Configure networking, identity and access management, compute, storage, databases, load balancers, DNS, firewalls and customer connectivity.
• Translate approved architecture into development, UAT, staging, production, High Availability and Disaster Recovery environments.

Infrastructure as Code, platforms and CI/CD

• Implement version-controlled Infrastructure as Code using Terraform and develop secure, reusable modules for repeatable customer environment builds.
• Deploy, configure and manage OpenShift and Kubernetes platforms, including networking, ingress, storage, certificates, RBAC, secrets and workload resources.
• Build and maintain CI/CD pipelines and cloud automation using approved tools such as Ansible, Helm, GitOps, Python and Bash/Shell.

Security, resilience, monitoring and cost

• Apply cloud security, compliance and governance requirements across IAM/RBAC, encryption, secrets, network controls, operating systems and platform configuration.
• Implement backup, High Availability and Disaster Recovery practices and validate recovery against defined RTO and RPO requirements where applicable.
• Monitor performance, availability, security and cost; optimize scalability, resilience, capacity and cloud spending without compromising service requirements.

Migrations, delivery and technical escalation

• Assess and support infrastructure and workload migrations, including dependencies, cutover planning, rollback, validation and post-migration stabilization.
• Troubleshoot complex infrastructure, cloud-platform, CI/CD and deployment issues during implementation, testing, go-live and major technical escalations.
• Complete production-readiness checks, acceptance evidence, knowledge transfer and formal handover; routine operational ownership remains with Production Support.

Standards, collaboration and responsible AI adoption

• Develop cloud and infrastructure standards, architecture records, reusable modules, implementation guides, operational runbooks and support documentation.
• Collaborate with developers, security teams, architects, DBAs, network specialists, project teams and customers to deliver complete working environments.
• Use approved AI tools for IaC, pipeline development, automation, troubleshooting and documentation. Review, test and security-validate outputs and protect confidential data in line with company policy.

Must-haves (to thrive in this role)

Experience & education

• 5+ years of relevant experience in cloud infrastructure, platform engineering, DevOps, infrastructure or system engineering.
• Proven experience independently building and implementing customer or production environments end to end, including migration and production go-live activities.
• A degree in computer science or a related field, or an equivalent qualification.

Cloud, platforms & infrastructure

• Hands-on experience with AWS, Azure or an equivalent enterprise platform.
• Experience with on-premises or hybrid infrastructure, not only public cloud.
• Hands-on experience with OpenShift and/or production-grade Kubernetes, together with strong Linux administration and troubleshooting skills.
• Strong knowledge of networking, IAM, compute, storage, databases, load balancing, DNS, firewalls, private connectivity and TLS.

Automation

• Strong hands-on Terraform experience, including reusable modules, state management, version control and controlled infrastructure changes.
• Experience building CI/CD pipelines and automation using Ansible, Python, Bash/Shell or equivalent tools.

Operations & collaboration

• Experience with cloud monitoring, security, compliance, backup, HA/DR, scalability and cost optimization.
• Strong troubleshooting, customer-facing communication, documentation and cross-team collaboration skills, with responsible adoption of approved AI tools.
