About Photon Eflux, LLC
Photon Eflux, LLC, a small-business limited liability company based in Huntsville, Alabama, operates as a child entity of Crossflow Technologies Inc. and holds a single federal prime contract vehicle: a GSA Federal Supply Schedule (Multiple Award Schedule) with a $96.3 million ceiling, awarded February 24, 2023, running through February 23, 2028. The vendor supplies labor services to civilian federal agencies nationwide across 266 labor categories, from technician through chief engineer roles, with no security-cleared positions offered.
Photon Eflux's GSA Schedule labor portfolio spans a broad capability range. Entry-level positions include Technician I roles at $35.07 per hour (high school education, no experience required) and Business Analyst III positions at $81.15 per hour (bachelor's degree, two years experience). Mid-spectrum work encompasses Hardware Tester V roles at $114.26 per hour and Program Analyst VI positions at $138.65 per hour. Senior technical capacity is represented by Electrical Engineer IX roles at $172.53 per hour (bachelor's degree, eight years experience) and Senior Engineer VI positions at $212.05 per hour (bachelor's degree, fifteen years experience). The top of the rate scale carries Chief Engineer V roles at $342.05 per hour (master's degree, thirty years experience). Education requirements span high school through master's degree; no roles require security clearance. Occupational categories include business analysis, hardware testing, general and electrical engineering disciplines, and technical support functions across the civilian federal market.
The vendor's federal footprint is entirely concentrated on the GSA Schedule: the single prime vehicle accounts for 100% of awards and combined potential value ($96.3 million). No subcontract work is present in the source data. GSA Federal Acquisition Service is the sole customer agency in the available award record. Because the award date is February 2023 and the most recent activity timestamp in the source is July 2026, task order activity data against the schedule is not present; the source captures the vehicle itself rather than downstream ordering patterns.
Photon Eflux operates as a subsidiary of Crossflow Technologies Inc., a for-profit Subchapter S corporation also headquartered at 15980 Chaney Thompson Road SE in Huntsville. Crossflow holds prime federal contract positions; no information on the parent's specific capability portfolio is present in the source.
