About the role

As a Consulting Principal, AI-Led Mainframe Modernization, you will make an impact by leading complex mainframe transformation engagements and applying generative AI and AI-enabled engineering capabilities to accelerate modernization from discovery through cloud migration and stabilization.

You will work collaboratively with client executives, enterprise architects, business and technology leaders, engineering teams, and AI/ML professionals to define modernization strategies, architect target-state solutions, and deliver large-scale legacy transformation programs.

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.

We strive to provide flexibility wherever possible. Based on this role’s business requirements, this is a remote position open to qualified applicants in the United States with some travel involved.

  • Proven track record delivering end-to-end mainframe modernization, beyond advisory and assessment, including code conversion, application decomposition, API enablement, data migration, cloud migration, cutover, and go-live.
  • Hands-on experience applying generative AI and LLM-enabled capabilities to modernization, including code comprehension, business-rule extraction, automated code conversion/refactoring, documentation, test generation, and AI-assisted estimation.
  • Strong knowledge of mainframe modernization, cloud, and engineering platforms, including technologies such as IBM z/OS Connect, AWS Mainframe Modernization, Micro Focus/OpenText, Heirloom, Raincode, Docker, Kubernetes, CI/CD, microservices, middleware, and at least one major cloud platform such as AWS, Microsoft Azure, or Google Cloud.
  • Strong consulting and client-facing experience, including the ability to architect complex transformation solutions, engage senior client stakeholders, lead cross-functional teams, manage technical risks, and communicate the business value and ROI of AI-enabled modernization.

These will help you succeed

  • Practical experience designing and validating AI-assisted code conversion pipelines, including prompt engineering, LLM evaluation, accuracy benchmarking, AI output-quality controls, responsible-AI practices, and human-in-the-loop validation.
  • Experience developing or scaling AI-enabled modernization accelerators or intellectual property, including inventory analyzers, code translators, business-rule extraction engines, test-case generators, or modernization workbenches.
  • Strong understanding of cloud-native architecture, application portfolio rationalization, DevOps, MLOps, containerization, microservices, service mesh, and enterprise architecture frameworks such as TOGAF.
  • Experience delivering complex modernization engagements across industries such as insurance, banking and financial services, healthcare, and retail, working across business SMEs, architects, developers, DevOps, and AI/ML engineering teams.
  • Relevant certifications such as AWS Solutions Architect, Azure Solutions Architect, Google Cloud Professional Cloud Architect, Azure AI Engineer, AWS AI/ML certifications, TOGAF, or equivalent credentials.
