Job Description

The L2 Engineer is the second-tier technical support layer within Zybisys's 24x7 managed cloud operations. This role owns the escalation queue from L1, performs deep-dive troubleshooting and root cause analysis, implements approved infrastructure changes, and manages the day-to-day configuration and administration of cloud and hybrid on-premises environments.

This is a hands-on technical role requiring strong Azure administration skills, solid networking and security platform knowledge, and the ability to independently resolve complex infrastructure incidents. The L2 Engineer is also a key contributor to operational improvement configuring monitoring rules, writing runbooks, and driving automation of repeatable tasks.

Key Responsibilities

Incident Management & Escalation Handling

• Own all L1-escalated incidents perform structured deep-dive troubleshooting, establish scope of impact, and drive resolution within SLA thresholds.
• Lead root cause analysis (RCA) for P1 and P2 incidents; produce clear, structured RCA reports with timeline, contributing factors, and corrective actions within agreed timelines.
• Coordinate war-room responses during major incidents liaising across L1, specialist, DevOps, and vendor support teams to restore service as quickly as possible.
• Maintain accurate and timely ticket documentation throughout the incident lifecycle; ensure all escalations have clear handover notes and status updates.
• Identify recurring incident patterns and proactively recommend permanent fixes, monitoring improvements, or runbook additions to reduce repeat escalations.

Infrastructure Administration & Change Management

• Administer Azure resources across multi-region environments VM provisioning and decommissioning, disk and snapshot management, VNet configuration, NSG rule management, and resource tagging.
• Manage Windows Server (2019/2022) and Linux (RHEL/Ubuntu) at an advanced level — OS hardening, service configuration, performance tuning, log analysis, and patch management.
• Implement and validate approved changes through the change management process; participate in change advisory board (CAB) reviews and post-implementation testing.
• Manage hybrid connectivity — ExpressRoute, Site-to-Site VPN, and Azure Arc-connected on-premises resources; troubleshoot connectivity degradation and failover scenarios.
• Administer identity and directory services: Azure AD, ADFS, hybrid identity, Conditional Access policies, and group policy management for enterprise user and device environments.
• Oversee storage operations: NetApp ONTAP volume management, snapshot scheduling, SnapMirror replication health, and Azure-native storage account administration.

Security Platform Operations

• Configure and manage Palo Alto NGFW firewall rules, security policies, NAT policies, and URL filtering profiles per approved change requests and client infosec policy directives.
• Administer Zscaler ZIA and ZPA — manage forwarding rules, user policies, SSL inspection profiles, and connector health for secure internet and private application access.
• Manage Trend Micro EDR policy groups, agent deployment, exclusion lists, and alert response actions; coordinate with the infosec team on policy tuning requirements.
• Operate CyberArk PAM — manage safes, account onboarding, access provisioning, and session recording in line with privileged access policies.
• Implement and document all security configuration changes with full change record traceability; ensure no security platform change is made without an approved change record.

Monitoring, Observability & Automation

• Configure and maintain Prometheus alerting rules, scrape targets, and recording rules; build and manage Grafana dashboards for infrastructure, application, and network observability.
• Develop and tune Azure Monitor alert rules and Log Analytics (KQL) queries for hybrid environments; reduce false positives and improve signal-to-noise ratio across all alert streams.
• Configure sFlow and NetFlow collectors and visualizations for network traffic baseline analysis, anomaly detection, and capacity reporting.
• Evaluate APM tool data (Dynatrace, AppDynamics, Azure Application Insights, or equivalent) and work with application teams to resolve performance degradation issues.
• Write and maintain operational runbooks, SOPs, and post-incident playbooks; contribute automation scripts (PowerShell, Python, Bash) to eliminate repetitive manual tasks.

Vendor & OEM Coordination

• Raise and manage support cases with Microsoft, Palo Alto, Zscaler, NetApp, Trend Micro, CyberArk, and other OEM vendors; drive cases to resolution with accurate reproduction data and clear escalation paths.
• Track open vendor cases, maintain status communication with internal stakeholders, and coordinate vendor-recommended fixes through the change management process.
• Participate in vendor maintenance windows, firmware upgrades, and product lifecycle activities for all managed platforms.

Documentation & Knowledge Contribution

• Produce high-quality RCA reports, change records, and technical documentation that can be consumed by L1 teams and operations leads.
• Maintain and continuously improve the operations knowledge base — document new solutions, update runbooks after every major incident, and identify knowledge gaps.
• Mentor and upskill L1 engineers through guided troubleshooting sessions, knowledge transfer, and structured feedback on escalated tickets.
