Program & Delivery Management

• Lead cross-functional teams—architects, developers, QA, and business analysts—in executing mainframe modernization projects on time, within budget, and to quality standards.

• Establish and own the program governance framework, including reporting cadences, escalation paths, and change management protocols.

• Identify and proactively mitigate risks across technical, operational, and organizational dimensions.

• Ensure compliance with applicable security, regulatory, and data governance requirements throughout transformation programs.

Solution Design

• Partner with technical architects to design modernization solutions tailored to clients’ unique environments and constraints.

• Evaluate existing mainframe ecosystems, identify optimization opportunities, and propose migration architectures leveraging modern cloud-native patterns and DevOps practices.

• Oversee quality assurance and validation processes to confirm that modernized systems meet performance, reliability, and functional requirements.

People & Practice Development

• Lead, mentor, and develop a team of modernization professionals, fostering a culture of continuous learning, accountability, and innovation.

• Define talent and capability development priorities for the practice, identifying skill gaps and sponsoring targeted growth initiatives.

• Communicate complex technical and program status to both technical and non-technical audiences with clarity and confidence.

This role may require up to 100% travel based on client engagement requirements.

Basic Qualifications:

• Minimum 8+ years of consulting experience including leadership of mainframe modernization or large-scale legacy transformation programs.

• In-depth knowledge of legacy mainframe platforms (IBM z/OS, CICS, DB2, COBOL, IMS) and their modernization pathways.

• Hands-on familiarity with major cloud providers (AWS, Azure, GCP) as modernization destinations.
