Job description

Role & responsibilities

Technical leadership

• Own technical design and delivery for IBM i initiatives, ensuring solutions are secure, resilient, and supportable.
• Provide day-to-day technical direction to developers (coding standards, design reviews, estimation, and prioritisation).
• Lead root-cause analysis for major incidents and drive permanent fixes (problem management).
• Partner with architecture, infrastructure, security, and product owners to align delivery with strategic roadmaps.
• Ensure documentation is fit for purpose: solution designs, runbooks, support guides, and knowledge articles.

Hands-on IBM i development

• Design, develop, and maintain IBM i applications using RPGLE (Free preferred), CL/CLLE, COBOL (as applicable).
• Work with DB2 for i (SQL, performance tuning, indexing strategies, locking/journalling considerations).
• Apply IBM i operational concepts: subsystems, job queues, output queues, work management, and scheduling.
• Implement robust exception handling, logging, and recovery patterns to improve operational resilience.

Production support & operational excellence

• Provide L3 production support and technical oversight for L2 teams; participate in on-call/major incident support as required.
• Drive stability improvements through trend analysis, defect prevention, and proactive monitoring enhancements.
• Own release readiness: deployment planning, back‑out strategies, post‑release validation, and production sign‑off.

Data migration & integration

• Lead/execute data migration activities(analysis,mapping,ETL,reconciliation,cutover planning,validation & Implementation).
• Enable and consume integrations using API concepts (REST/JSON), service enablement patterns, and middleware where relevant.
• Ensure integrations are observable and supportable (logging, alerts, error handling, retries).

Automation, Python, and AI (preferred)

• Build automation using Python (or similar) for migration, operational tasks, reconciliation, reporting, and validation.
• Explore AI-enabled improvements (e.g., log analytics, anomaly detection, incident triage support) in collaboration with platform/tooling teams.
• Promote CI/CD and test automation practices for IBM i delivery where tooling supports it.

Agile delivery & ways of working

• Lead technical delivery in Agile (Scrum/Kanban): refinement, estimation, sprint planning, and continuous improvement.
• Coach the team on engineering practices (quality gates, peer reviews, definition of done, and technical debt management).
