Enterprise Modernisation Lead

About the Role

As an Enterprise Modernisation Lead at Rensora, you will own and drive end-to-end modernization engagements for some of the world's largest organisations. You will work with C-suite stakeholders and enterprise architecture teams to assess legacy portfolios, design migration strategies, and orchestrate the transformation of critical systems from mainframes, monoliths, and on-premise infrastructure to modern cloud-native architectures.

This is a senior leadership role that sits at the intersection of technology and business transformation. You will define modernization roadmaps, manage cross-functional delivery teams, and ensure that migrations are executed safely, on schedule, and with measurable business outcomes. You will leverage Rensora's ModernZAI platform and AI-powered analysis tools to accelerate discovery, planning, and execution phases.

You will bring deep experience with legacy technologies and a proven track record of leading complex, multi-year transformation programs. You understand the risks, politics, and technical realities of enterprise modernization — and you know how to navigate all of them.

What You'll Do

Lead end-to-end modernization engagements — from initial portfolio assessment through migration execution and post-migration optimisation
Conduct legacy system audits across mainframe (COBOL, PL/I, JCL), midrange (AS/400, RPG), and monolithic application estates
Design migration strategies: re-platform, re-factor, re-architect, or replace — with clear rationale, risk analysis, and business case for each approach
Build and present modernization roadmaps and business cases to C-suite and board-level stakeholders
Manage cross-functional delivery teams including engineers, architects, and client-side technical leads
Drive adoption of Rensora's ModernZAI platform for automated code analysis, dependency mapping, and migration planning
Establish governance frameworks for large-scale migrations — change management, risk mitigation, rollback planning, and quality assurance
Mentor junior consultants and contribute to Rensora's modernization methodology and knowledge base

What We're Looking For

7+ years of experience in enterprise modernization, digital transformation, or IT consulting — with at least 3 years in a lead or principal role
Deep hands-on experience with legacy technologies: mainframe (z/OS, CICS, DB2), midrange (AS/400), or large-scale monolithic applications
Proven track record of designing and executing multi-million-dollar migration programs from legacy to cloud-native architectures
Strong understanding of modern cloud platforms (AWS, Azure, GCP) and cloud-native patterns (microservices, containers, serverless)
Experience with change management methodologies and organizational transformation in large enterprises
Excellent stakeholder management skills — able to build trust and alignment with technical teams and executive sponsors alike
Program management capability — budgets, timelines, risk registers, and cross-team coordination
Outstanding written and verbal communication, with the ability to translate complex technical concepts for business audiences

Nice to Have

Experience with AI-assisted modernization tools or automated code transformation
Certifications in cloud architecture (AWS Solutions Architect, Azure Architect, GCP Professional) or project management (PMP, PRINCE2)
Background in regulated industries (financial services, healthcare, government) where modernization carries additional compliance requirements
Experience building and scaling consulting practices or delivery teams
Familiarity with TOGAF, Zachman, or other enterprise architecture frameworks
