At Mace, our purpose is to redefine the boundaries of ambition. We believe in creating places that are responsible, bringing transformative impact to our people, communities and societies across the globe. To learn more about our purpose, culture and priorities, visit our strategy site.

Within our business we harness our unique combination of leading-edge practical expertise and project deliveryconsultancy to unlock the potential in every project.

The Project

We are seeking an experienced Project Scheduler to develop and maintain OT (Operational Technology) and MES (Manufacturing Execution System) schedules for multiple pharmaceutical API facility projects at a single geographic location. This contractor role will work as part of a scheduling team, with responsibility for creating and maintaining loosely coupled OT/MES schedules that integrate with master project schedules maintained by other team members. Projects include facility expansions and one greenfield API manufacturing facility.

Our Values

• Safety first - Going home safe and well
• Client focus – Deliver on our promise
• Integrity – Always do the right thing
• Create opportunity – For our people to excel

You’ll Be Responsible For

• 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 the 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

You’ll Need To Have

• Minimum of 10 years of project scheduling experience, including extensive experience with Primavera P6
• 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
• Background in API or pharmaceutical manufacturing facility projects strongly preferred
• Experience with both expansion projects and greenfield facility construction
• 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.
• 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
