About the company
Sienna Technologies, Inc., a for-profit Subchapter S corporation headquartered in Mukilteo, Washington, manufactures specialized high-performance sensors, multi-chip module packages, and advanced electronic components for aerospace, defense, and space applications, operating as a prime contractor on 98% of its federal awards with no set-aside designation. The vendor has maintained federal contracting activity since 2002 and competes on full-and-open basis, with technical capabilities concentrated in silicon carbide and silicon nitride sensor fabrication, hermetic packaging, extreme-temperature component assembly, and RF/microwave attenuators — areas where Sienna holds exclusive manufacturing processes and tooling that frequently trigger sole-source procurements under FAR 13.106-1(b)(1)(i).
Sienna's customer concentration is heavily weighted toward NASA and Department of Defense space and aerospace programs. The top five customers by award count account for 64% of recent awards, dominated by NASA's Shared Services Center (19 awards, $2.3 million combined potential value) and NASA Glenn Research Center (17 awards, $794 thousand combined potential value), followed by the Department of the Navy (11 awards), Department of the Air Force (6 awards), and NASA headquarters (5 awards). By combined potential value, the top five customers account for 72%, with the Air Force Materiel Command Research Laboratory placing five awards worth $1.2 million and the DOD Missile Defense Agency accounting for $1.1 million across two awards. Sienna's capability portfolio reflects this customer concentration: recent representative work includes a $143,750 sole-source purchase order from NASA SSC in June 2024 for packaging of durable and reliable pressure-temperature sensor chips capable of withstanding 900 degrees Celsius and 500 psi, a $143,750 February 2024 order from NASA SSC for high-performance silicon carbide pressure-temperature sensor packaging with aluminum nitride and Kovar tube brazed construction, and a $53,228 January 2026 order from Naval Sea Systems Command for attenuators.
Activity has been episodic over the past five years — one or two awards annually from 2020 through 2022, then five awards in 2024 and three in 2026 through November. Only two awards face ultimate completion in the next twenty-four months (combined potential value $126 thousand), indicating minimal recompete exposure in that window. Sienna subcontracts sparingly: recent sub work includes aluminum nitride absorber procurement for Verus Research LLC on a Space-Compatible Anechoic Technologies Retrofit program and radar panel procurement and integration for Leidos on a classified MJOLNIR add-work effort. Primary NAICS concentration aligns with the sensor and component focus: Research and Development in Physical, Engineering, and Life Sciences (20 awards), Other Electronic Component Manufacturing (11 awards), and Engineering Services (11 awards). The combined potential value across all 90 awards totals $8.5 million, though obligated dollars ($16.7 million) exceed that figure, reflecting backlog and multi-year component orders typical of specialized manufacturing for extreme-environment aerospace applications.
