Carolyn Mosinski

Carolyn W. Mosinski serves as a Contract Specialist within the C5I Division 1 Alexandria under the U.S. Coast Guard and Department of Homeland Security, where she manages the acquisition of mission-critical information technology and communications systems essential to maritime domain awareness and operational resilience. She plays a pivotal role in executing full lifecycle procurements for enterprise-grade C5I infrastructure, including secure software development, satellite telecommunications, and wireless communications equipment. Her acquisitions directly support the modernization of secure, interoperable IT ecosystems that enable real-time decision-making across Coast Guard operations. Mosinski collaborates with a diverse range of vendors, including systems integrators, defense contractors, and specialized technology providers focused on secure communications and command-and-control platforms. While no single contractor dominates her portfolio, she consistently engages firms with expertise in satellite networking, custom software development, and telecommunications equipment manufacturing. Her procurement approach emphasizes technical compliance, cybersecurity readiness, and vendor performance accountability, fostering long-term partnerships with contractors capable of supporting complex, high-assurance environments. Her contracting patterns reflect a strong preference for open competition, with 88.9% of acquisitions conducted without set-asides, indicating a focus on broad market competition for mission-critical capabilities. Nevertheless, she maintains a deliberate 11.1% commitment to Total Small Business Set-Asides under FAR 19.5, ensuring opportunities for qualified small businesses to contribute to national security missions without compromising technical requirements. Mosinski’s primary NAICS focus includes 541990 (Professional Technical Services), 517410 (Satellite Telecommunications), and 541511 (Custom Computer Programming), reflecting her specialization in integrated C5I solutions. She routinely procures enterprise software, secure satellite ground systems, radio frequency equipment, and maintenance services for industrial communications infrastructure, demonstrating deep expertise in the technical domains of maritime command, control, and intelligence systems.
