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.

• Lead end‑to‑end delivery of technical projects involving ERP implementations, upgrades, integrations, and data transformation

• Document application requirements, data mappings, and integration contracts (APIs, messaging, ETL), ensuring alignment with enterprise architecture
• Support application release management, regression planning, environment coordination (DEV/TEST/UAT/PROD), and configuration management
• Collaborate with QA to define test strategy and oversee test execution (functional, integration, performance, failover) across application and infrastructure layers

• Partner with business owners to understand strategy, current pain points, and desired outcomes; define problem statements, success metrics, and business cases
• Elicit, document, and validate business, functional, and non‑functional requirements (availability, performance, security, compliance)
• Create and maintain process flows, system context diagrams, data flows, and user stories that clearly connect business needs to technical solutions
• Act as primary liaison between business, infrastructure, security, and application teams; facilitate workshops, drive decisions, and manage expectations
• Coordinate with business users, functional leads, architects, developers, QA teams, and external vendors to define scope, timelines, risks, and deliverables
• Facilitate requirements gathering, solution workshops, sprint planning, testing cycles, UAT, cutover planning, and go‑live readiness
• Ensure proper governance, documentation, change control, and stakeholder communication throughout the project lifecycle

• Manage and support onsite and offshore development teams, ensuring alignment on priorities, deliverables, quality standards, and communication cadence
• Work with product owners and application teams to plan and deliver new features, integrations, and upgrades across ERP, CRM, web, and line‑of‑business systems

• Work with infrastructure teams (cloud, data center, network, security) to design and deliver environments that meet scalability, resiliency, and performance requirements
• Translate business and application requirements into infrastructure specifications (compute, storage, network, backup/DR, identity, monitoring)
• Coordinate implementation of core infrastructure changes: server builds, OS upgrades, virtualization, storage/network changes, load balancers, VPN, and end‑user devices
• Ensure operational readiness: handover to support, runbooks, SOPs, monitoring and alerting configuration, and alignment with ITIL processes (incident, change, problem)

• Bachelor’s degree in Information Technology, Computer Science, Engineering, Business, or related field
• 10+ years of project management experience in enterprise technology environments Proven experience managing ERP and systems integration projects end‑to‑end
