Your responsibilities

• Incident & Problem Management: Own the Root Cause Analysis (RCA) process for production incidents—diagnose, resolve, and put preventive measures in place so issues don't recur.
• Production Monitoring & Support: Continuously monitor service health, detect anomalies early, and act before they become full-blown incidents.
• Deployment Execution: Trigger and oversee release deployments through existing CI/CD pipelines; troubleshoot failed deployments and coordinate rollbacks when needed.
• Environment Oversight: Keep Pre-Production and Production environments stable and aligned, ensuring they behave as expected day to day.
• Operational Improvement: Identify recurring pain points and propose automation or tooling to reduce toil. Improve observability coverage (dashboards, alerts, log queries) and contribute to disaster recovery drills.
• Knowledge Management: Document operational procedures, known issues, and resolution steps to build a reliable knowledge base.
• Cross-team Collaboration: Work shoulder-to-shoulder with development and platform teams to triage issues, clarify operational requirements, and close the feedback loop between prod and dev.

Our requirements

• 5+ years in IT operations, application support (L2/L3), or a similar production-facing role.
• Proven track record of owning incidents end-to-end—from alert to RCA to prevention.
• 2+ years working within an ITIL framework (incident, problem, and change management).
• Experience working in Agile delivery environments alongside development teams.
• Advanced English communication skills—ability to explain technical issues clearly to both engineers and non-technical stakeholders.
• Proficiency with log analysis and alerting tools (Splunk, Apica, Sysdig).
• Experience with Observability tooling (Prometheus, Grafana—reading dashboards, tuning alerts).
• Comfortable operating services running on Kubernetes and Linux CLI (checking pod health, reading logs, triggering restarts).
• Familiarity with Jenkins pipelines for executing and troubleshooting deployments, and proficiency in GIT.
• Experience with relational databases (Oracle, DB2)—querying, interpreting execution plans, and identifying data-related incidents.
• Working knowledge of Spring/Hibernate application behavior, Kafka message flows, and XML/JSON payloads to effectively trace issues through the stack.

Optional

• Experience with Helm deployments.
• Java/J2EE development background (highly beneficial for reading stack traces and collaborating with devs).
• IBM DataStage operational experience.
• Scripting skills (Bash, Python) for automating repetitive operational tasks.
• Ansible knowledge for applying configuration changes in controlled scenarios.
