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.
