Position Summary

The Transition / Senior Project Manager (SPM) is the single‑threaded project leader for a new portfolio. This role has a dual mandate: (1) lead the end‑to‑end transition and mobilization of the portfolio launches, and (2) evolve into the Sr. PM responsible for ongoing portfolio program coordination across all client verticals and all functional teams (Operations, Recruiting, HR, Compliance, Training, Scheduling, Logistics, Reporting/Analytics, and Finance/Billing). The SPM owns the master portfolio plan, governance cadence, RAID and decision management, and cross‑vertical initiatives that improve performance, reduce friction, and ensure consistent execution.

Primary Objectives

• Transition success: Mobilization milestones achieved on schedule; readiness gates met before go‑live; minimal day‑one disruption.
• Portfolio operating rhythm: Predictable governance cadence across the three verticals with clear decisions, actions, and escalation SLAs.
• Cross‑vertical coordination: Dependencies managed across Retail, Data Centers, and Corporate; shared processes standardized where possible.
• Operational transparency: Executive‑ready reporting and dashboards that surface risks early and drive corrective actions to closure.
• Continuous improvement: A living roadmap of cross‑functional initiatives that reduce fire drills, improve service consistency, and strengthen client experience.

Core Responsibilities

• A) Transition Leadership (Mobilization Phase)
• Own and maintain the integrated transition plan and master tracker (tasks, owners, dependencies, deliverables, readiness gates, and timeline).
• Drive transition governance (weekly localized + weekly global cadence), producing clear status, actions, decisions, and escalation paths.
• Lead critical‑path execution across workstreams: staffing ramp, recruiting pipeline, onboarding, training/OJT, post orders/SOP readiness, access/badging, uniforms/equipment, scheduling readiness, and Day‑1 reporting readiness.
• Implement and enforce site‑level go/no‑go readiness criteria and document sign‑offs prior to service commencement.
• Coordinate go‑live and stabilization support (first ~2 weeks post start) and transition handoff into steady‑state ownership.
• B) Senior PM – Portfolio Coordination (Steady‑State Phase)
• Serve as the portfolio Sr. PM coordinating across Retail, Data Centers, and Corporate verticals and all functional teams.
• Maintain a living portfolio roadmap of cross‑vertical initiatives (process improvements, tooling/reporting enhancements, staffing model adjustments, training refreshes, and governance improvements).
• Run ongoing portfolio governance: consolidate vertical updates, manage dependencies, track commitments, and drive decision closure.
• Own portfolio‑level change control: intake change requests, impact scope/cost/schedule/risk, route approvals, and update plans/communications.
• Standardize repeatable operating processes across verticals where appropriate (templates, readiness checklists, reporting packs, post order workflow, escalation playbooks).
• Coordinate quarterly/periodic business reviews support: ensure metrics, narratives, and action plans are prepared, consistent, and complete.
• C) Program Controls (RAID, Decisions, Reporting, and Governance)
• Own the RAID log (risks/assumptions/issues/decisions) and decision register; ensure each item has an owner, due date, and next step.
• Build and publish executive‑ready status packs (portfolio health, readiness, staffing, training, post orders, access/badging, financial/billing readiness, key risks/issues).
• Establish decision SLAs and escalation paths; facilitate rapid resolution of cross‑functional blockers.
• Maintain strict version control of portfolio artifacts; ensure audit‑ready documentation where required.
• Own portfolio KPI framework and ongoing KPI tracking; define metric owners, targets, and cadence; drive corrective actions from insights.
• Build and maintain Ops dashboards for leadership (staffing, training, compliance posture, incidents, readiness by site, and action closure).
• Own compliance tracking in partnership with Compliance (licensing, certifications, post orders version control, audit readiness evidence).
• Plan, prepare, and lead Quarterly Business Reviews (QBRs) with the Portfolio VP and Operations leadership, including KPI rollups, narrative, risks, and improvement plan.
• D) Cross‑Functional Leadership
• Operations: coordinate site readiness, supervision model inputs, coverage plans, and local execution cadence.
• Recruiting/HR: align recruiting ramp, screening/onboarding, and time‑to‑fill targets; maintain visibility into hiring constraints.
• Compliance/Training: coordinate licensing/certifications, training standards, OJT completion evidence, and post orders compliance cycles.
• Scheduling/Logistics: drive schedule build/QA/publication, uniform/equipment distribution readiness, and site readiness logistics.
• Reporting/Finance: ensure consistent reporting cadence and support billing/invoice readiness controls where required.

Key Deliverables

• Master portfolio plan and trackers (transition + steady‑state roadmap).
• Governance calendar and meeting outputs (status, actions, decisions, escalations).
• RAID log and decision register (living).
• Readiness gates and site sign‑off evidence (during mobilization).
• Portfolio reporting pack and metrics rollups (weekly/monthly/QBR support as applicable).

Required Qualifications

• 7+ years of program/project management experience leading multi‑site operational programs, mobilizations, or transitions (security services, facilities, logistics, field operations, or similar).
• Demonstrated success driving cross‑functional execution and decision‑making without direct authority.
• Strong project controls: integrated planning, dependency/critical path management, change control, and risk management.
• Advanced Excel‑based tracking/reporting proficiency; strong written and verbal executive communication skills.
• Experience in regulated/compliance‑heavy environments (licensing, training documentation, audits) preferred.

Preferred Certifications

• PMP/PgMP, PRINCE2, Lean/Six Sigma (Green Belt+) or equivalent.
• Security industry exposure (ASIS or similar) helpful but not required.

Skills & Competencies

• Portfolio coordination: ability to manage multiple verticals, dependencies, and competing priorities.
• Executive communication: concise, action‑oriented reporting and decision framing.
• Operational realism: understands field execution constraints; builds plans that teams can follow.
• Systems mindset: treats scheduling, timekeeping, reporting, and billing readiness as critical‑path items.
• Documentation rigor: version control, audit‑ready evidence, and repeatable templates.

KPIs for Success

• Transition: % sites meeting go/no‑go gates by target date; go‑live readiness pass rate; stabilization issue burn‑down.
• Portfolio: on‑time delivery of cross‑vertical initiatives; decision cycle time; action closure rate; reduction in recurring escalations/fire drills.
• Operational visibility: on‑time status pack delivery; quality of reporting (completeness, accuracy, usefulness).

Working Conditions / Travel

• Travel to priority sites may be required during mobilization, readiness validation, and go‑live support.
• Flexible hours may be required during go‑live windows and major events.
• Must be comfortable operating in high‑security environments with strict confidentiality and access controls.
