Senior OpenShift Engineer – Tieto Tech Consulting (m/f/d)

Job Description

Tieto Tech Consulting (MentorMate from 2001 to 2026) is looking for a highly skilled and motivated Senior OpenShift Engineer, a professional who will join a project within a Telecom Team for our respectful client BICS.

Join the software engineering team for our customer BICS – a global telecommunications enabler – and impact how billions of people communicate. 

Build solutions used by top enterprises and carriers: from network for voice, messaging, and data, to 5G IoT, roaming, signaling, and cloud communications businesses. Beyond traditional telecommunications, BICS is at the forefront of enabling digital transformation, cloud interconnectivity, IoT ecosystems, and next-generation mobile services, helping customers navigate the evolving global connectivity landscape. 

You won’t find micromanagement here, but you will find the support of a local People Manager, a diverse team, and an AI-enabled culture shaped to increase your productivity instead of replacing people. 

Become a part of the BICS community at Tieto Tech Consulting that has been growing since 2010 and enjoy the comfortable and stable environment where new ideas thrive. 

Areas of Responsibility

• Engage with business stakeholders to gather requirements and design solutions that align with engineering standards and support business needs.

• Perform patching and upgrades of OpenShift clusters, ArgoCD, GitLab CI, and related components in compliance with change-management procedures. 
• Design, implement, and maintain backup, disaster recovery, and redundancy strategies. 
• Participate in on-call / standby rotation to support critical platform and infrastructure services and ensure service continuity. 
• Support daily operations including trend analysis, root cause analysis, monitoring, troubleshooting, and resolution of platform issues to ensure high availability and reliability. 
• Implement and enforce security best practices, including RBAC, vulnerability management, and compliance controls. 
• Improve alerting, monitoring, and observability capabilities across OpenShift and related systems. 
• When OpenShift-related workload is limited, perform general system administration activities, including Linux server administration, infrastructure maintenance, and support of data center services as part of the infrastructure team. 
• Produce and maintain up-to-date documentation, including architecture diagrams, operational procedures, and runbooks. 
• Provide knowledge transfer, mentoring, and training to colleagues on OpenShift, GitLab, and related infrastructure technologies. 

Qualifications

• 4+ years of relevant professional experience; alternatively, equivalent professional certifications (including Red Hat OpenShift training) combined with at least 5 years of experience.
• Proven hands-on experience deploying, operating, and maintaining OpenShift and GitLab CI platforms.
• Strong experience with infrastructure automation practices, particularly using Ansible.
• Solid background in Linux system administration within enterprise or datacenter environments.
• Ability to document architectures, configurations, and standards, and to develop and maintain SOPs and training materials.
• Upper-intermediate level of English (both spoken and written).

Will be an advantage
