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.

• 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.
