Senior Integrated Master Scheduler (IMS Lead)

Job Description

Job DescriptionPosition details

• Title: Senior Integrated Master Scheduler (IMS Lead)
• Location: Washington, DC (hybrid; periodic on-site as required)
• Employment type: Full-time W-2 (or long-term staff augmentation/contract-to-hire, if preferred)
• Travel: Occasional CONUS travel to installations and stakeholder sites
• Citizenship: U.S. Citizen required
• Security clearance: Ability to obtain and maintain a DoD clearance; active clearance preferred (level depends on tasking)

Primary responsibilities

• IMS development and baseline control
  • Develop, baseline, and maintain the Program Integrated Master Schedule (IMS) from schedule architecture through execution, integrating acquisition, engineering, regulatory/permitting, site preparation and integration, safety/security, commissioning, and transition to operations.
  • Establish schedule governance: coding structures (WBS alignment), calendars, milestones, schedule dictionary, and configuration management.
  • Support baseline change control (BCR) and maintain traceability of assumptions, constraints, and decision gates.
• Multi-organization integration and facilitation
  • Integrate schedules from government teams and multiple contractors (prime/subs, reactor vendor/integrator, A/E, construction, cybersecurity/physical security, installation energy/microgrid teams).
  • Lead working sessions with functional leads to elicit logic ties, constraints, deliverable-based dependencies, and approval gates.
  • Translate technical and acquisition realities into defensible network logic and an executable status cadence.
• Schedule quality, compliance, and analytics
  • Ensure schedule quality consistent with GAO schedule best practices and produce documented schedule health metrics.
  • Conduct DCMA 14-point (or equivalent) schedule checks; identify defects (logic gaps, constraints, high float, lags, missing predecessors/successors) and drive corrective actions.
  • Perform critical path / driving path analysis, near-critical path monitoring, constraint analysis, and scenario planning (what-if, recovery, acceleration).
  • Lead or support Schedule Risk Analysis (SRA) / Monte Carlo forecasting to produce confidence dates and risk-informed recommendations.
• Status, reporting, and executive communication
  • Own the schedule status cycle (weekly/biweekly/monthly): data calls, progress validation, integration of updates, and publication of schedule narratives.
  • Develop executive-ready reporting: milestone achievement, critical path movement, schedule variance trends, and forecast rationale.
  • Support senior governance forums, baseline reviews, and major program reviews with schedule products and briefings.
• Tools and process discipline
  • Serve as the scheduling tool and process owner (Primavera P6 required). Ensure consistent schedule standards, access controls, and audit trail.
  • Maintain the Schedule Management Plan (SMP): status rules, percent complete methodology, schedule-level change control workflow, and interfaces to cost/EVM (if applicable).

Required qualifications

• 8-12+ years of progressive scheduling and/or project controls experience supporting large, complex, multi-year programs (federal/DoD preferred).
• Demonstrated experience building and managing a program-level IMS that integrates multiple organizations and workstreams.
• Advanced Primavera P6 capability (required) and strong competence with MS Project and Excel-based analytics/reporting.
• Working knowledge of GAO schedule best practices and DCMA 14-point schedule assessment methods; able to remediate schedule quality issues and defend schedule credibility.
• Strong facilitation skills and ability to translate engineering/acquisition inputs into defensible schedule logic.
• Strong writing and briefing skills; comfortable presenting schedule drivers and forecast rationale to senior government and contractor stakeholders.
• Bachelor’s degree (engineering, construction management, business, or related) or equivalent experience.

Preferred qualifications

• Experience supporting EVMS/EVM programs (schedule/cost integration; control account alignment; baseline change control discipline).
• Schedule Risk Analysis (SRA) experience using tools such as Deltek Acumen Risk/Fuse, Primavera Risk Analysis, Safran, @RISK, or equivalent.
• Certifications: AACE PSP (Planning and Scheduling Professional), PMI-SP, and/or PMP.
• Domain experience in regulated or safety/security critical environments (energy/nuclear, critical infrastructure) and/or installation integration programs (microgrids, force protection, emergency management integration).
• Active DoD security clearance.
