Join to apply for the Team Lead Infrastructure & Network Engineering Team role at erasys GmbH

We are looking for an experienced and driven Team Lead to guide our Infrastructure & Network Engineering team. Our current infrastructure is datacenter-based, and we are planning a transition to a hybrid setup that integrates AWS cloud services. As the team lead, you will oversee a group of skilled system and network engineers, ensure the availability, scalability, and security of our infrastructure, and play a key role in strategic decisions regarding infrastructure automation, observability, and Kubernetes-based platforms.

This is a highly technical leadership role where you will balance hands-on expertise with strategic oversight. You’ll collaborate cross-functionally to support deployment pipelines, networking operations, and our overall DevOps maturity.

Key Responsibilities

• Lead, mentor, and support a team of system and network engineers.
• Drive the design and implementation of a hybrid infrastructure strategy (datacenter + AWS).
• Oversee networking operations including routing, firewalls, VPNs, and secure remote access.
• Own Kubernetes cluster operations, ensuring high availability, scalability, and automation.
• Implement and enforce infrastructure-as-code practices using tools like Gitlab, Terraform and Ansible.
• Drive observability initiatives using tools such as Prometheus, Grafana, and New Relic.
• Collaborate with other engineering teams to ensure infrastructure aligns with development and product needs.
• Establish incident response strategies and contribute to on-call procedures.
• Ensure compliance with security, privacy, and operational policies (e.g., GDPR, internal standards).
• Evaluate and manage third-party tools, hardware, and services relevant to infrastructure and networking.
  
• 5+ years of experience in system and/or network engineering roles.
• At least 2 years in a leadership or technical management position.
• Experience working with both datacenter environments and AWS, or leading migration to cloud-based infrastructure.
• Deep knowledge of Kubernetes in production, including setup, scaling, and observability.
• Strong networking expertise (TCP/IP, VPNs, routing, switching, firewalls).
• Hands-on experience with infrastructure automation (Gitlab, Terraform, Ansible, etc.).
• Familiarity with monitoring/alerting platforms and managing SLOs/SLAs.
  

Nice to have would be

• Experience with Rancher for Kubernetes cluster management.
• Experience with Foreman and/or Puppet for provisioning and configuration management.
• Experience with service meshes like Istio.
• Background in IT security or compliance (e.g., ISO 27001, SOC 2, GDPR).
• Experience with CI/CD pipelines and GitOps workflows.
• Relevant certifications such as AWS Solutions Architect, Certified Kubernetes Administrator (CKA), and/or CCNP.
