About the company
Sierra Circuits, Inc., a woman-owned small business based in Sunnyvale, California, manufactures and assembles printed circuit boards (PCBs) and microelectronics components for federal defense and space programs as a prime contractor (76% of recent awards) and subcontractor across the Department of Defense and civilian agencies. Sierra Circuits holds SBA certifications as a woman-owned business, American Indian-owned enterprise, and Subcontinent Asian American-owned minority business, competing across both small-business set-asides and full-and-open procurements.
Sierra Circuits' concrete capability is high-reliability PCB design, fabrication, assembly, testing, and evaluation to military and space specifications, with sustained focus on bare PCB manufacturing (80 of 152 awards) and electronic assembly work. Representative prime awards include a $1.2 million multiple-award BPA with the Defense Microelectronics Activity established June 2023 (extended through June 2026) for microelectronics design and fabrication supporting trusted electronics for national security systems; a $28,022 firm-fixed-price purchase order from NASA's Shared Services Center (September 2026) for fabrication and assembly of 22-layer high-reliability printed circuit boards for an HPSC processor card with delivery to NASA Goddard Space Flight Center; a $95,638 sole-source purchase order from Naval Air Warfare Center (January 2023) for PCB fabrication supporting research and development; and a $89,184 purchase order from NASA Shared Services Center (August 2023) for PCB fabrication and assembly of a Lunar Inverter Breadboard Prototype. Across both prime and sub roles, all work is performed in Sunnyvale, California to military and aerospace specifications including NASA/GSFC standards, IPC-2221, IPC-2222, IPC-6011, and IPC-6012ES.
Customer concentration sits predominantly with Department of Defense commands. The top five customers account for 63% of award count: Defense Microelectronics Activity (17 awards, $3.4 million combined potential value), Naval Air Warfare Center (18 awards, $1.4 million), Naval Sea Systems Command (33 awards, $333 thousand), NASA Shared Services Center (14 awards, $342 thousand), and Office of Naval Research (8 awards, $309 thousand). By dollar value, DMEA dominates at 71% of the top-five share, while Naval Sea Systems Command places the most orders by count despite smaller per-award magnitude. Sierra Circuits holds two parent BPAs: a $1.2 million vehicle with DMEA (HQ072723A0800, 11 task orders at $484 thousand combined potential value) and a $1.285 million vehicle awarded February 2026 (HQ072726AE001, 2 task orders at $420 thousand), both set aside for total small business and running through 2026 and 2031 respectively.
Award activity has grown from four awards in 2022 to twenty-five in 2024, with a moderation to sixteen in 2025 and seven awards in 2026 year-to-date (through September). Only two awards ($421 thousand combined potential value) reach ultimate completion within the next twenty-four months, presenting minimal near-term recompete exposure on the prime side. In its subcontractor role, Sierra Circuits supplies PCB fabrication and assembly to Lockheed Martin Corporation (recurring across multiple NGI AUR development pre-KP3 programs involving printed wiring boards and circuit card assemblies), Northrop Grumman Systems Corporation (bit-flip suppressed fluxonium gates research and development), Triad National Security LLC (Los Alamos National Laboratory operations and management supporting electrical equipment procurement), the Johns Hopkins University Applied Physics Laboratory (SSN advanced sensors and systems materials), Mantech Advanced Systems International, and HII Mission Technologies Corp on vertical launching systems interface testing. The subcontract footprint spans defense RDT&E, space exploration, and specialized national-security microelectronics development, with recurring sub relationships anchored in PCB and assembly manufacturing rather than systems integration or prime-contract management.
