Senior Application and Operation Support Engineer

Our requirements

• 5+ years of experience 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 of experience working within an ITIL framework (incident, problem, change management).
• Experience working in Agile delivery environments alongside development teams.
• Advanced English communication skills, with the ability to explain technical issues clearly to both engineers and non-technical stakeholders.
• Monitoring & Observability: Proficiency with Splunk, Apica, Sysdig, Prometheus, and Grafana (reading dashboards, tuning alerts).
• Infrastructure: Comfort operating services on Kubernetes and Linux CLI (e.g., checking pod health, reading logs, triggering restarts).
• CI/CD & Version Control: Familiarity with Jenkins pipelines for deployments and troubleshooting, and proficiency in GIT.
• Application & Data Layer: Experience with relational databases (Oracle, DB2)—querying, interpreting execution plans, and troubleshooting data incidents.
• Architecture Knowledge: Working knowledge of Spring/Hibernate behavior, Kafka message flows, and XML/JSON payloads to trace issues through the stack.

Optional

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

Your responsibilities

• Incident & Problem Management: Own the RCA process for production incidents—diagnose, resolve, and implement preventive measures.
• Production Monitoring & Support: Continuously monitor service health, detect anomalies early, and proactively prevent incidents.
• Deployment Execution: Trigger and oversee release deployments through existing CI/CD pipelines; troubleshoot failures and coordinate rollbacks when necessary.
• Environment Oversight: Maintain the stability and alignment of Pre-Production and Production environments.
• Runbook & Knowledge Management: Document operational procedures, known issues, and resolution steps to build a reliable team knowledge base.
• Operational Improvement: Identify recurring pain points and propose automation to reduce manual toil. Improve observability coverage (dashboards, alerts, log queries) and contribute to disaster recovery drills.
• Cross-team Collaboration: Work closely with development and platform teams to triage issues, clarify requirements, and close the feedback loop between production and development.
