Role Overview

We are seeking an experienced iSeries / IBM i Administrator with 6+ years of hands‑on experience to support a clients managed IBM i environment. You will manage assigned L2 administration and operational activities from investigation through resolution, communicate risks and blockers proactively, and implement changes through established change-management and approval processes.

This role combines system administration, PTF and software maintenance, backup and recovery, security and authority management, journaling, performance tuning, monitoring, environment refreshes and vendor-supported issue resolution. You should have strong IBM i fundamentals, take ownership of operational deliverables and work independently. The position involves rotational support and participation in scheduled disaster‑recovery and environment‑refresh activities.

Key Responsibilities

IBM i System Administration

• Administer IBM i environments, including system configuration, CPU, memory and storage tuning, workload optimization, memory pools, job priorities, subsystems, job queues, job descriptions and class definitions.
• Investigate and resolve L2 incidents and service requests; take ownership through closure and escape proactively when technical, access, vendor or schedule risks arise.
• Coordinate with IBM and third‑party vendors for defect investigation, support cases, fixes and resolution tracking.
• Execute application user profile creation, object authority requests and other approved operational requests using documented procedures.

Patching, Upgrades & Software Management

• Own IBM i OS and PTF activities, including monitoring applicable HIPER and defective PTF notifications, impact assessment, planning, communication, implementation and validation.
• Perform or support IBM i OS upgrades, firmware and HMC updates, security patching, open‑source package maintenance, and installation, configuration and maintenance of approved third‑party software.
• Plan outage‑dependent activities, distinguish work that can be completed in advance, and maintain accurate implementation, validation and backout documentation.

Backup, Recovery, DR & Environment Management

• Administer and troubleshoot backup and recovery operations using BRMS and VTL/tape‑based processes.
• Participate in scheduled disaster‑recovery testing and execution, including DR/HA switch activities, recovery validation and issue documentation.
• Execute approved QA and test environment refreshes from production backups and verify completion against documented controls.
• Support Db2 journaling, data replication and related operational recovery requirements.

Security, Database & Service Requests

• Administer IBM i user and object security across object, IFS and file levels; support authority reviews, access remediation and approved security changes.
• Support network‑security and IBM i security tooling activities, security assessments and remediation within the managed‑services scope.
• Execute approved Db2 data fixes using provided DML scripts and configure application secrets or field‑level encryption through established procedures.
• Set up B2B file transfers using pre‑developed templates and execute documented deployment requests without introducing application‑code changes.

Monitoring, Performance & Automation

• Monitor system health and operational alerts; analyze QHST history logs, jobs, subsystems, queues, storage, workload and performance indicators.
• Perform performance tuning and capacity analysis, identify trends, and provide resource‑utilization and capacity‑planning inputs.
• Use CL/CLLE and IBM i SQL Services to improve repeatability and operational efficiency; contribute automation using Python, Ansible or Bash where appropriate and approved.
• Maintain runbooks, system documentation, change records, operational reports and knowledge‑transfer materials for client‑specific tooling.

Service Delivery Expectations

• Work effectively in a rotational coverage model, complete clear shift handoffs, and support scheduled after‑hours or weekend activities for DR tests and environment refreshes.
• Follow incident, request, change and problem‑management processes; protect production stability and maintain complete audit evidence.
• Meet defined service levels and operational measures for response, resolution, backlog health, quality, automation and customer satisfaction.
• Take ownership of assigned deliverables, investigate issues before escalating, communicate potential delays early, and work independently following knowledge transfer.
