Proven experience scheduling OT/MES implementations in a pharmaceutical or other regulated manufacturing environment for at least 5 years
Direct experience working within a team of schedulers on large capital projects
Expert proficiency in Primavera P6 (required for this role)
Strong understanding of schedule integration techniques and loose coupling methodologies
Knowledge of MES platforms and their implementation lifecycles
Understanding of OT systems including SCADA, DCS, PLC, industrial networks, and process automation
Familiarity with pharmaceutical CSV requirements and validation protocols
Ability to work with complex multi-project P6 databases
Advanced critical path method (CPM) and schedule network analysis
Experience defining and managing interface points between loosely coupled schedules
Strong collaborative skills with ability to work effectively within a scheduling team
Excellent communication skills for coordinating with CQV, construction, engineering, and IT teams
Self-motivated with ability to work independently while maintaining team alignment
Detail-oriented with strong analytical capabilities

Nice To Haves

Background in API or pharmaceutical manufacturing facility projects strongly preferred
Experience with both expansion projects and greenfield facility construction
Experience with API manufacturing facilities and containment requirements
Knowledge of GAMP 5 2nd Ed guidelines and 21 CFR Part 11 requirements
Background in both brownfield (expansion) and greenfield facility projects
Previous experience with multi-project P6 environments and enterprise project structures

Responsibilities

Develop and maintain detailed OT/MES implementation schedules in Primavera P6 for multiple concurrent API facility projects
Create Work Breakdown Structures (WBS) specific to automation systems, MES platforms, industrial networks, and process control systems
Establish and maintain loose coupling between OT/MES schedules and master project schedules to enable independent tracking while preserving critical dependencies
Define interface points, handoffs, and integration milestones between OT/MES scope and other project workstreams (construction, process equipment, utilities, CQV)
Work closely with CQV (Commissioning, Qualification, and Validation) schedulers to align validation dependencies and testing sequences
Coordinate with master scheduler(s) on each project to ensure proper integration of OT/MES activities into overall project timelines
Participate in integrated scheduling reviews to identify cross-discipline dependencies and conflicts
Maintain consistent coding structures, calendars, and reporting standards across the scheduling team
Contribute to portfolio-level schedule analysis and reporting
Schedule automation system design, configuration, FAT/SAT activities, and deployment
Plan MES software implementation phases including system build, integration testing, and cutover activities
Coordinate industrial network infrastructure installation and commissioning (switches, firewalls, server infrastructure)
Schedule PLC/DCS programming, SCADA configuration, and system integration activities
Plan for phased go-lives and production cutover windows in coordination with plant operations
Understand and schedule around API manufacturing constraints (containment, environmental controls, batch processing)
Coordinate OT/MES activities across multiple API facilities at Boulder site
Account for shared resources (system integrators, IT personnel, vendors) across concurrent projects
Schedule facility-specific requirements for both expansion projects and the greenfield facility
Integrate CSV (Computer System Validation) activities into OT/MES schedules
Schedule IQ/OQ/PQ, or similar, activities for automation and MES systems
Identify and communicate OT/MES-related schedule risks and mitigation strategies
Update schedules weekly based on progress from system integrators, vendors, and internal teams
Generate OT/MES-specific reports and contribute to integrated project reporting
