Hybrid work model

Descrizione del lavoro

Nordea in Poland (Warsaw or Gdansk) is seeking an IT Infrastructure Specialist to support the Commercial Cards platform. The role is hybrid with responsibilities spanning incident management, deployments, and security remediation.

You will own day-to-day operations, coordinate major incidents, and drive improvements across a Kubernetes-based environment and legacy WebLogic stack while collaborating with cross-functional teams.

Competenze

• 5+ years in IT operations, application operations or infrastructure, including ownership of production systems.
• Solid Linux and Windows Server administration.
• Hands-on Kubernetes and container experience: kubectl, Docker, deployments, troubleshooting pods.
• Administration of Java application servers (WebLogic preferred; Tomcat, JBoss or similar accepted).
• Working knowledge of Git: branching and pull requests.
• DB2 or SQL: writing queries to investigate and verify data issues.
• Strong ITIL practice: incident, major incident, change and problem management, using an ITSM tool.
• Good understanding of networking and security: TLS/certificates, firewalls, network zones, SSO.
• Scripting (PowerShell and/or Bash).
• Experience with monitoring and alerting tools (e.g. Grafana, AppDynamics, Prometheus).
• Ability to analyse Java application logs and stack traces.
• Clear written and spoken English, including incident updates for non-technical stakeholders.
• Ownership and independence: makes decisions, escalates well, and stays calm under pressure.

Mansioni

• Own operations end to end: incidents, service requests and work orders in BMC Helix, handled within SLA.
• Lead major incidents: coordinate the teams involved, communicate with stakeholders and drive root‑cause analysis.
• Monitor applications and infrastructure (Grafana, AppDynamics, batch jobs), tune alerting and dashboards, and run problem management to remove recurring issues.
• Plan and execute production changes, including recurring work such as monthly Windows patching.
• Manage certificates and TLS, and remediate security and vulnerability findings (scan results, CVEs, TLS issues).
• Troubleshoot across the stack: logs, pods, Java application servers, DB2 databases, SFTP and file‑transfer flows.
• Make configuration changes through Git (branches, pull requests) and run deployments via Jenkins across dev, test, pre‑prod and prod.
• Automate repetitive operational work with scripts.
• Act as the operations contact for platform, network, database and other infrastructure teams: raise, track and follow up requests.
• Own the runbooks, work instructions and knowledge base in Confluence, and coach colleagues on operational practices.
• Drive the operational side of migrating legacy workloads to the new platform and decommissioning old environments.
