Marie.S. Feinberg

Marie S. Feinberg serves as Radios Branch Chief at W6QK Acc-apg under the Department of the Army’s W91CRB organization, where she leads the acquisition and integration of advanced radio frequency systems critical to tactical communications and battlefield intelligence. In this role, she oversees the end-to-end procurement lifecycle for next-generation software-defined radios, cognitive networking platforms, and secure waveform technologies that enable interoperable, resilient communications across expeditionary and contested environments. Her portfolio directly supports the Army’s modernization priorities in aeronautical instrumentation and real-time data fusion, ensuring fielded systems meet stringent MIL-STD and NATO interoperability requirements. Feinberg collaborates with a broad ecosystem of defense technology providers specializing in RF hardware, embedded software, and signal processing solutions. While no single contractor dominates her portfolio, she consistently engages firms with proven expertise in software-defined radio architectures, cryptographic key management, and adaptive spectrum access technologies. Her procurement approach emphasizes technical rigor, rapid prototyping, and seamless integration with existing battlefield networks, fostering partnerships with vendors capable of delivering field-upgradable, modular systems under tight developmental timelines. Feinberg’s contracting activity reflects a strict focus on open competition, with 100% of her acquisitions designated as non-set-aside. This reflects the technical complexity and mission-critical nature of the systems she procures, which often require specialized engineering capabilities beyond the scope of most small business concerns. While she does not prioritize socioeconomic set-asides, her team maintains rigorous evaluation criteria to ensure performance, security, and sustainment are paramount. Her primary procurement focus lies in NAICS 541511 (Custom Computer Programming Services), reflecting her emphasis on software-centric radio systems, waveform development, and embedded firmware for tactical platforms. She procures advanced signal processing algorithms, secure communication protocols, and battlefield data analytics tools that enable real-time situational awareness, underscoring her deep expertise in software-defined radio and cognitive electronic warfare domains.
