The UI/UX Modernization Lead will shape the design strategy, align it with COBOL-driven workflows and C#-compatible front-end technologies, and drive an achievable modernization schedule. This position requires a visionary designer with strong leadership, systems thinking, and the ability to translate legacy complexity into modern user experiences.

  • Develop the design vision, principles, and roadmap for the modernization effort.
  • Analyze, deconstruct, and reimagine 750 legacy screens, grouping workflows into coherent user journeys.
  • Conduct stakeholder interviews, workshops, and usability validations to inform design decisions.
  • Create wireframes, prototypes, high-fidelity designs, and supporting documentation.
  • Build or refine a scalable design system to support consistent and efficient delivery.
  • Partner with engineers to ensure technical feasibility and alignment with modernization constraints.
  • Define Agile-ready design stories, estimates, sequencing, and acceptance criteria.
  • Participate in PI Planning, Sprint Planning, Refinements, and Reviews as the program’s design authority.
  • Provide leadership, guidance, and feedback to the team throughout the modernization cycle.
  • Identify risks early and recommend mitigation strategies to maintain schedule integrity.

Required Abilities / Experience

  • 7+ years of experience in UI/UX design, including lead-level responsibility.
  • Demonstrated success modernizing legacy or mainframe applications, ideally at scale (300+ screens).
  • Strong understanding of design considerations for systems interacting with COBOL or other mainframe workflows.
  • Experience building and governing enterprise-level design systems.
  • Ability to break complex design work into Agile-friendly increments and partner effectively with engineering teams.
  • Strong portfolio showing workflow redesign, information hierarchy, and transformation of outdated interfaces.
  • Excellent communication skills, with the ability to present concepts to technical and non-technical audiences.
  • Proven success facilitating workshops, gathering requirements, and leading consensus-building discussions.

Desired Abilities / Experience

  • Experience working directly with mainframe modernization technologies, terminal emulator UI updates, or COBOL modernization tools.
  • Familiarity with cloud modernization patterns.
  • Experience supporting government, enterprise, or highly regulated modernization efforts.
  • Knowledge of DevSecOps processes.
  • Background developing modernization plans or migration roadmaps for large application portfolios.
