In this role, you will:

• Lead end-to-end mainframe modernization engagements , including discovery, application and infrastructure assessment, inventory and dependency analysis, target‑state architecture, code and data transformation, cloud migration, cutover, and stabilization.
• Define modernization strategies and transformation roadmaps across rehost, replatform, refactor, re‑architect, and replace approaches, incorporating AI‑driven portfolio analysis, complexity assessment, estimation, and solution design.
• Apply generative AI and AI‑enabled engineering solutions such as GitHub Copilot, Azure OpenAI, Amazon Q, Claude, ChatGPT, code translators, and rule‑extraction capabilities to accelerate code comprehension, conversion, documentation, testing, and engineering productivity.
• Provide architecture and technical governance throughout the transformation lifecycle, including modernization patterns, cloud‑native architecture, AI tool selection, responsible‑AI guardrails, human‑in‑the‑loop validation, and quality assurance of AI‑generated code.
• Advance AI‑led modernization capabilities by developing reusable accelerators and intellectual property, mentoring consulting and engineering teams, supporting client workshops and solutioning, and contributing to thought leadership and go‑to‑market initiatives.
