Job Summary:

We are seeking a highly skilled Solution Infrastructure Architect to lead the design and implementation of an AIX infrastructure upgrade to IBM Power10 systems. This role involves end-to-end architectural oversight, system integration planning, risk management, and collaboration with cross-functional teams to ensure a smooth, secure, and efficient migration from legacy Power systems (e.g., Power8/Power9) to Power10.

Key Responsibilities:

• • Architect and lead the upgrade strategy and roadmap for AIX systems transitioning to IBM Power10 hardware.

• • Design scalable, high-performance, and resilient infrastructure solutions aligned with enterprise architecture standards.

• • Assess existing AIX workloads, dependencies, and integration points to define optimal migration paths.

• • Develop technical architecture documents, including HLDs and LLDs, covering compute, storage, network, and backup considerations.

• • Evaluate and incorporate virtualization technologies (e.g., PowerVM, VIOS), LPAR design, and micro-partitioning strategies.

• • Define and enforce security hardening, patching, and compliance requirements throughout the upgrade lifecycle.

• • Work closely with UNIX/Linux administrators, DBAs, application owners, and vendors to coordinate the transition.

• • Establish rollback, disaster recovery, and business continuity procedures related to the upgrade.

• • Provide technical leadership, mentoring, and knowledge transfer to infrastructure and support teams.

• • Manage and mitigate risks through proactive issue resolution and contingency planning.

• • Participate in project planning, cost estimation, and timeline development with project managers and stakeholders.
