Role Overview

We are seeking an experienced Senior R&D Application Separation & Migration Technical Lead to drive the end-to-end technical separation, migration, and stabilization of mission-critical R&D and Engineering applications. In this high-visibility role supporting a Big 4 consulting client in the manufacturing sector, you will lead discovery, target architecture readiness, technical cutover execution, and hypercare across complex multi-tier environments.

Key Responsibilities

• Lead end-to-end separation and migration of R&D and Engineering applications across discovery, planning, target-state implementation, cutover, and stabilization.
• Conduct technical discovery to document current-state architecture, data models, integration landscapes, infrastructure dependencies, and migration scope.
• Define target-state configurations, technical prerequisites, object dependencies, and environment-specific changes across DEV, SIT, UAT, Staging, and Production.
• Develop migration wave strategies, technical readiness gates, cutover runbooks, rollback plans, and operational milestones.
• Oversee target infrastructure readiness, coordinating servers, databases, network connectivity, DNS, firewalls, certificates, service accounts, middleware, monitoring, and disaster recovery.
• Collaborate with data teams to establish requirements for data extraction, cleansing, transformation, reconciliation, archival, and purging.
• Manage cross-functional technical dependencies spanning IAM, licensing, vendor support, integration, and security teams.
• Direct SIT/UAT execution, mock migrations, dress rehearsals, defect triage, production cutover, and post-migration hypercare.
• Maintain migration RAID logs, drive root-cause analysis for blockers, support decommissioning activities, and ensure a smooth operational handover to steady-state support.

Required Qualifications

• 15+ years of enterprise experience across application implementation, systems administration, infrastructure engineering, technology transformation, and application separation/migration.
• Proven track record leading complex technical migrations, enterprise carve-outs, divestitures, TSA exits, or re-platforming initiatives.
• Deep expertise in multi-tier enterprise application architecture and SDLC deployment lifecycles (DEV, SIT, UAT, Staging, PROD).
• Hands-on platform expertise across Windows Server, Linux, application servers, load balancers, enterprise storage, and networking.
• Strong database and connectivity fundamentals, including SQL Server, Oracle, TCP/IP, DNS, firewalls, ports, SSL/TLS certificates, and reverse proxies.
• Working knowledge of enterprise identity systems, including Active Directory, SSO, SAML/OAuth, IAM, service accounts, and least-privilege security models.
• Demonstrated experience managing dependencies across APIs, middleware, ETL pipelines, licensing, and security boundaries.
• Solid grasp of data migration and validation principles, including profiling, mapping, reconciliation, backup/recovery, and business continuity.
• Hands-on technical leadership during mock cutovers, dry runs, technical dress rehearsals, production cutovers, and hypercare troubleshooting.
• Excellent stakeholder management skills, with the ability to bridge low-level technical problems with business impact, executive reporting, and risk mitigation.

Preferred Qualifications

• Domain experience supporting R&D, Engineering, Product Development, PLM, PDM, project controls, or engineering document management platforms.

• Hands-on or architectural familiarity with specialized platforms such as:

• Siemens Teamcenter

• Autodesk Vault

• Sopheon Accolade

• Hexagon EcoSys

• SiliconExpert

• Experience with enterprise ERP integrations, specifically SAP, enterprise middleware, REST/SOAP APIs, and enterprise reporting tools.

• Cloud architecture experience across Microsoft Azure, AWS, or hybrid enterprise hosting models.

• Prior exposure to regulated or controlled manufacturing/engineering environments.

• Relevant professional certifications (e.g., PMP, PgMP, SAFe, ITIL, AWS/Azure Solutions Architect, VMware, Linux).
