• Exposure to modern DevOps/automation tools on IBM i.
• Formal IBM Certifications (e.g., IBM Certified System Administrator - IBM i).
• Experience supporting major IBM i ERPs or WMS platforms.
• Hands-on with Power11 capacity planning, shared processor pools, and dynamic LPAR moves.
• Firmware/HMC/VIOS lifecycle planning aligned to IBM best practices for newest hardware generations.
• Storage acceleration experience (flash/NVMe), SAN zoning/NPIV, and performance troubleshooting across the I/O stack.
• PowerHA advanced scenarios (IASP, multi site), Precisely MIMIX tuning and audit, or storage based replication.
• Security add ons (e.g., Fortra Powertech), SIEM integration, and MFA for IBM i.
• DevOps awareness: RDi, RPG free format exposure, Git based deployment tooling, TurnOver/ARCAD/X Analysis.
• Hybrid/Cloud DR patterns (IBM PowerVS), cloud based backup targets, or cross site orchestration.
• Observability integrations (Robot Monitor/Navigator SQL Services, and hooks to enterprise APM/alerting).
• ITSM process maturity (ServiceNow/Jira) and CMDB hygiene.
• Bilingual (EN/FR) communication is an asset.
• IBM Certified System Administrator – IBM i (or equivalent experience).
• HA/DR vendor certifications (Precisely/Rocket).
• Security: CompTIA Security+, CISSP (plus) or IBM Security specialties.
• ITIL v4 Foundation.

Responsibilities

• Administer IBM i environments (LPARs, HMC, hardware/storage).
• Manage the OS/PTF lifecycle, monitor subsystems, batch operations, advanced job scheduling, and system housekeeping.
• Own the DR strategy end-to-end. Operate and tune Maxava replication, manage the IBM PowerVS Cloud DR environment, and execute regular, validated failover testing.
• Architect and maintain the backup strategy utilizing BRMS, ensuring data integrity and successful restore testing.
• Provide infrastructure-level support for the RPG-based ERP/WMS. Coordinate application deployments, change management, and troubleshoot across application, database, and OS layers.
• Tune CPU, memory, and disk I/O. Optimize batch jobs and Db2 for i database performance using modern IBM i SQL services.
• Manage user profiles, object authority, system values, audit logging (QAUDJRN), and ensure compliance with security frameworks.
• Maintain network connectivity, secure protocols (SFTP, APIs), and EDI integration flows.
• Automate routine administration tasks using CL and QShell/bash.
• Maintain rigorous SOPs, runbooks, and configuration management (CMDB).

Benefits

• Flexible working arrangements
