Senior Cloud SRE

Cloud Infrastructure SRE / Tier 4 Engineer

As a Cloud Infrastructure SRE / Tier 4 Engineer, you will join a specialized engineering task force dedicated to preventing and resolving the most critical and strategic customer issues encountered in the field.

Our global team of experienced engineers has a deep understanding of the lower layers of private cloud infrastructure. Together, we work on practical solutions, continuously learning and adapting. We collaborate closely, share knowledge, and tackle challenges head-on.

If you're an engineer eager to understand the core of cloud technologies and looking for a team that values hands-on expertise, you'll fit right in with us.

What you will learn and contribute to

- Maintain and enhance Red Hat private cloud: You’ll work extensively with Nokia Container Services (NCS) and CloudBand Infrastructure Software (CBIS), private cloud solutions based on Kubernetes and OpenStack.
- Deep Dive Troubleshooting: Starting from high-level Kubernetes error messages, you’ll navigate through multiple layers until pinpointing issues—even down to kernel-level bugs.
- Automate and Develop: Spend 30–50% of your time developing automation to prevent recurring issues. Solve it once, automate for the future. Use your Python skills to create health checks and improve reliability.
- Continuous Learning: In our rapidly evolving tech landscape, ongoing learning is a cornerstone.
- Collaborate with Developers and Engineers: Work closely with developers and product engineers to bridge infrastructure and software, ensuring seamless product delivery.
- Mode of Operation: This role requires participation in a follow-the-sun scheme with 12-hour shifts (within regulatory limits) or participation in on-call rotations to ensure business continuity during emergencies.

Your skills and experience

- Linux Expertise: Strong familiarity with Linux distributions; we primarily use Red Hat and CentOS.
- Networking Foundations: Solid understanding of networking fundamentals (VLANs, IP routing). Experience with Calico, Multus, and Open vSwitch is a plus.
- Problem-Solving Mindset: Excellent troubleshooting skills and analytical thinking to address complex challenges.
- Scripting and Automation: Proficiency in Bash and Python, or willingness to learn, plus familiarity with Ansible.
- Containerization & Virtualization: Knowledge of Podman, Kubernetes, Helm, and/or OpenStack; experience with KVM/QEMU is advantageous.
- Storage Systems: Experience with Ceph and Rook is highly valued.
- Database Expertise: Understanding of relational databases (MySQL, MariaDB) and experience with etcd.
- Monitoring and Logging: Familiarity with tools like ELK (Elasticsearch, Logstash, Kibana), Prometheus, and Grafana.
- Advanced written and spoken English.

It would be nice if you also had

- Proactive thinking and ownership mindset.
