About Riverside Engineering LLC
Riverside Engineering LLC, a woman-owned, minority-owned, economically disadvantaged small business subsidiary of Soliel LLC, operates as a prime contractor on defense systems engineering and IT infrastructure modernization programs, competing entirely through federal contracts (100% prime, zero subcontractor awards) with a focus on DISA and Navy customers. Riverside holds SBA designations as an SBA-certified economically disadvantaged women-owned small business and self-certified small disadvantaged business, positioning the company to compete both on set-aside vehicles and full-and-open contracts.
Riverside's customer base is concentrated in defense infrastructure. The top three funding agencies account for 100% of recent awards: the Defense Information Systems Agency (DISA) leads with eight awards totaling $627.8 million combined potential value, the Department of the Navy Information Warfare Systems Command holds four awards worth $38.3 million, and the Department of the Air Force Air Education and Training Command anchors the portfolio with a single award of $13.37 billion combined potential value. This concentration reflects Riverside's core position on DISA's Systems Engineering Technology and Innovation (SETI) IDIQ vehicle, where four task orders carry $69.5 million in combined potential value. Riverside also maintains task-order seats on the C4ISR Emerging PNT Technologies and ENCORE III Information Technology Services vehicles.
Recent representative work demonstrates Riverside's systems-engineering and infrastructure-security capability profile. A February 2026 DISA delivery order valued at $11.9 million covers electromagnetic spectrum architectures, data, and planning services supporting defense enterprise architecture engineering and policy. An April 2024 SETI task order for $25.4 million (set aside for total small business) provides Demilitarized Zone engineering program management support at Fort Meade, Maryland; in fiscal year 2024, this order invoiced $2.1 million across 4.3 FTEs with government-paid blended rates of $231.21 per hour, with one subcontractor performing 100 percent of contractor hours. A December 2026-expiring DISA delivery order (October 2023 award) carries a $32.3 million ceiling for public key infrastructure sustainment, a core DoD cryptographic-security mission. A smaller Naval Information Warfare Systems Command task order covers GPS, navigation, and timing platform integration and engineering support. The portfolio spans computer systems design services (five awards) and research and development in physical and engineering sciences (four awards), with IT systems development and electronics/communications engineering dominating the project-specific category (PSC) footprint.
Activity volume over the past five years shows sparse award frequency — three awards in 2019, two in 2020, then two in 2023, one in 2024, and one in 2026 — rather than consistent pipeline generation. One award (the public key infrastructure sustainment contract worth $32.3 million) reaches ultimate completion within the next twenty-four months and faces recompete exposure in that window. SCI-reported federal service-contract invoicing is limited to the single $2.1 million Demilitarized Zone order in fiscal year 2024; SCI data do not reflect Riverside's full federal revenue or the majority of its task-order potential. As a Soliel LLC subsidiary, Riverside operates within the parent's minority-owned, woman-owned small business posture and shares the Annapolis Junction, Maryland address with its parent entity.
