We bring talented, energetic, and immediately productive professionals to meet critical customer needs in systems engineering and integration, mission operations, program management, and strategic planning-helping teams deliver resilient capability to the mission with speed, quality, and focus.

Stellar Solutions is seeking a Senior Portfolio Acquisition Advisor to provide strategic acquisition and programmatic counsel supporting the Space-Based Environmental Monitoring mission within the broader Space-Based Sensing and Targeting portfolio.

This highly experienced advisor will support senior Government acquisition leadership as multiple programs, capabilities, stakeholders, and acquisition activities are aligned within an evolving portfolio construct. The advisor will bring the judgment and perspective of a seasoned defense acquisition professional who understands how to move beyond individual program execution and help leadership manage acquisition decisions across an integrated mission portfolio.

The ideal candidate brings significant experience leading or advising major Department of Defense or national security space acquisition programs and has operated at the Program Executive Officer, Portfolio Acquisition Executive, Program Manager, Deputy Program Manager, Senior Materiel Leader, or equivalent senior advisory level.

This individual will work closely with Government leadership, program offices, systems engineering organizations, operational stakeholders, industry, and other mission partners to help establish acquisition strategy, portfolio governance, decision frameworks, risk posture, priorities, and execution approaches that accelerate delivery of operational Environmental Monitoring capabilities.

Key Responsibilities

• Serve as a trusted senior acquisition advisor to Government leadership responsible for Space-Based Environmental Monitoring and related Space-Based Sensing and Targeting capabilities.
• Advise leadership on the development and evolution of acquisition strategies across a portfolio of programs, systems, services, and commercial capabilities.
• Support the transition from individual program-centric acquisition activities toward an integrated portfolio approach aligned to mission outcomes.
• Help establish portfolio-level governance, decision authorities, management rhythms, priorities, and executive-level review processes.
• Assess acquisition approaches across programs and identify opportunities to reduce duplication, streamline decision-making, align resources, and improve delivery speed.
• Advise Government leaders on acquisition trades involving cost, schedule, performance, technical maturity, operational need, risk, and industrial-base considerations.
• Support integration of acquisition strategies across space, ground, mission-processing, data, commercial-services, and operational capability elements.
• Provide strategic guidance regarding traditional acquisition pathways, rapid acquisition approaches, prototyping, commercial solutions, data-as-a-service models, and other flexible acquisition strategies as appropriate to mission needs.
• Help leadership evaluate where commercial capabilities can augment, complement, or accelerate Government-developed Environmental Monitoring capabilities.
• Support portfolio planning and alignment across legacy systems, systems currently in development, modernization efforts, commercial capabilities, and future mission needs.
• Advise on acquisition planning, milestone preparation, acquisition documentation, decision memoranda, program reviews, and executive-level briefings.
• Identify cross-program dependencies, acquisition risks, organizational seams, resource conflicts, and decisions requiring senior leadership attention.
• Support development of integrated portfolio roadmaps connecting operational requirements, capability gaps, acquisition activities, technical development, budgets, schedules, and fielding objectives.
• Provide independent assessment and recommendations regarding program health, contractor performance, acquisition strategy, schedule realism, technical risk, and execution challenges.
• Support coordination among Government program offices, operational organizations, systems engineering teams, contracting organizations, financial management personnel, industry partners, FFRDCs, SETA organizations, and other stakeholders.
• Mentor and advise Government and contractor personnel on acquisition strategy, program execution, risk management, stakeholder engagement, and executive decision support.
