Job description

Leidos is seeking a Program Manager (PM) to lead the capture-to-delivery transition and, upon award, to serve as the single point of accountability for program performance, cost, schedule, and customer satisfaction across a large, multi-year program to extend the existing Operational Network into a classified private multi-cloud capability (“ON-X”). The NATO Communications and Information Agency (NCIA) procurement is structured as a ten-year Indefinite-Delivery/Indefinite-Quantity (IDIQ) framework, through firm-fixed-price (FFP) Task Orders drawn from a Contractor-built Service Catalogue. Early Task Orders are expected to cover network takeover and transition planning, discovery and target-architecture design, and a Proof-of-Concept gate, followed by a hybrid mix of one-time delivery and steady-state managed-service outcomes spanning cloud platform engineering, identity and data services, AI platform services, secure access, digital workplace, cyber resilience, accreditation, and sovereignty assurance. The PM will own end-to-end delivery of the ON-X contract: integrating cost, schedule, and technical performance across a portfolio of firm-fixed-price Task Orders; managing the transition from the incumbent NATO-operated model to a Contractor-operated model; and building the governance, financial management, and risk-management rigor required to sustain a decade-long IDIQ relationship with a demanding, security-conscious international customer. The PM will be the primary customer-facing interface with the NCIA and will direct a multi-disciplinary team spanning cloud engineering, security accreditation, service management, and subcontractor/partner organizations.

Responsibilities:

Serve as the single point of accountability for overall program performance, cost, and schedule across all active Task Orders issued under the ON-X IDIQ. Plan, staff, and mobilize the program at contract start, including stand-up of the Project Management Office (PMO), integrated master schedule, and Purchaser-approved governance rhythm. Own Task Order-level and program-level financial management: budgeting, forecasting, Estimate-to-Complete, invoicing, and firm-fixed-price margin performance; apply FinOps discipline to cloud consumption and cost transparency obligations. Lead the takeover and transition of ON operations from the incumbent NATO-operated model, ensuring service-level continuity against the pre-handover baseline and demonstrable absorption of operational knowledge. Direct discovery, target-architecture design, and Proof-of-Concept execution, coordinating cross-functional teams (cloud/platform engineering, identity and data services, security and accreditation, service management) against Purchaser-approved gate criteria. Maintain traceability across Outcomes (HLOs), Implementation Requirements, the QASP, CDRL, Service Catalogue, and Task Orders, ensuring the program's delivery evidence stays audit ready. Own program risk management, including risks related to migration/cutover, accreditation and Authority to Operate timelines, sovereignty and jurisdictional-control obligations, and supply-chain/4th-party dependencies. Manage subcontractors and technology partners supporting the multi-cloud platform, ensuring performance, security, and compliance obligations flow down and are enforced. Act as the primary interface with the NCIA customer and NATO stakeholders for contract performance, escalations, and Award Fee/performance reviews; support Purchaser governance boards and quarterly reviews. Ensure compliance with applicable NATO security policy (including cloud-specific NATO SECRET directives), export control, and Leidos corporate contract-management standards. Report program status, financials, and risk to Leidos executive leadership and to the customer on an agreed cadence; prepare and present Integrated Program Baseline / resource-loaded schedule updates. Support proposal-to-execution continuity by contributing PM-domain input during remaining capture and Step 2 proposal activities, and by owning post-award transition-in planning. Mentor and develop program leadership and task leads; build a high-performing, security-cleared workforce able to sustain a ten-year program.

Required Qualifications are as follows:

Bachelors in Electronic Engineering, Computer Science, Telecommunications, or related discipline and 15+ years or more of experience; Masters and 12+ years or more of experience. 10+ years of program management experience managing large scale firm-fixed-price (FFP) contracts or Task Orders in a complex technical environment, including cost, schedule, and technical-performance accountability. 5+ years of experience with Information and Computer Technologies (ICT) procurement, implementation, migration and management. Demonstrated experience managing IT infrastructure, managed-services, or systems-integration programs of comparable scale and complexity. Proven experience serving as the primary customer-facing interface on programs involving multiple stakeholders and workstreams. Strong financial management skills, including budgeting, forecasting, Estimate-to-Complete, and variance analysis on fixed-price programs. Experience managing program risk, subcontractors, and cross-functional/matrixed teams Excellent executive-level written and verbal communication skills. Project Management certifications (e.g. PRINCE2 Agile Practitioner, Project Management Institute (PMI) Project Management Professional (PMP) or equivalent) and valid Information Technology Infrastructure Library (ITIL) Foundation Certificate at minimum Must have a current active NATO Secret level security clearance. High ability in speaking, writing, and understanding English is essential as all on-site work will be conducted in English. Minimum required level of English language of SLP3333 as defined in NATO STANAG 6001.

Desired skills are as follows:

Experience managing cloud infrastructure, cloud migration, or multi-cloud platform programs (IaaS/PaaS, DevSecOps pipelines, identity and data services, or secure cloud access) is highly desired. Prior experience supporting NATO, NCIA, a NATO Nation Ministry of Defense, or another international/coalition organization is desired. Experience with security accreditation processes (Authority to Operate, continuous compliance) in a classified or high-assurance environment. Familiarity with FinOps practices, cloud cost transparency/chargeback models, and cloud cost-management tooling. Experience with large-scale network or data-center takeover/transition-in from an incumbent operator, including operational knowledge transfer. Additional relevant certifications such as SAFe Agile, CISSP/CISM, an AWS/Azure/Google Cloud certification. Experience operating in a multinational, geographically distributed team environment, including coordination across allied or coalition partners.
