We are seeking an experienced Technical Project Manager with strong hands-on experience leading ERP, systems integration, and data transformation initiatives. This role requires a blend of project leadership, technical understanding, and cross-functional coordination to deliver complex enterprise technology projects on time and within budget.
The ideal candidate has successfully managed projects involving multiple ERP platforms, legacy and modern business systems, data migration and transformation, and distributed development teams including onsite and offshore programmers. This person must be comfortable working closely with business stakeholders, technical teams, vendors, and leadership to drive execution from requirements through deployment and post-go-live support.
This role requires the ability to thrive in a fast-paced environment, managing multiple projects simultaneously while maintaining high delivery standards. You must be able to juggle competing priorities, make rapid decisions under tight timelines, and adapt quickly to evolving requirements — all without losing quality or team alignment across concurrent workstreams.
