Sierra Space Broomfield CO expands defense work with new solar array factory
Sierra Space added 120 engineering and manufacturing roles in Broomfield during 2025 — mostly for solar panel production supporting classified defense satellites. Their new 68,000 sq ft Power Station Technology Center became operational last June, monopolizing the Colorado facility's output through 2026. If you're eyeing space-sector defense work, here's what their Broomfield expansion means for engineering hiring, salaries, and required clearances.
This guide covers Sierra Space's Colorado operations with 2026-specific data on:
- Batch-produced satellite solar arrays powering military contracts
- Secret/Top Secret clearance requirements for 70% of new roles
- Compensation comparisons against Lockheed Martin and Northrop Grumman
- How Sierra's defense pivot changes hiring criteria vs. legacy space companies
Solar tech dominates Broomfield operations
Sierra Space's Broomfield facility exclusively manufactures satellite solar arrays after their 2025 defense sector pivot. The factory produces 200+ solar wings annually for:
- U.S. Space Force missile warning satellites
- Orbital Reef commercial space station modules
- Classified "dark ops" spacecraft (per Aviation Week reports)
All manufacturing equipment was transferred from Ohio after Sierra won a $1.4B Space Development Agency contract. This consolidation makes Broomfield their singular production site for spacecraft power systems through at least 2028.
Defense work demands specific skills
Clearance needs
72% of 2025 Broomfield job postings required active security clearances:
- 60% mandated TS/SCI eligibility
- 12% required Secret level
- 28% were uncleared technical roles (supply chain, non-critical software)
"Sierra Space's Broomfield facility builds the solar wings powering America's next-gen spy satellites — but breaking in requires TS/SCI clearance first."
Engineering specializations
Glassdoor postings from March 2026 show these top hires:

Leadership impact on Broomfield’s defense pivot
Sierra Space’s Colorado operations reflect CEO Fatih Ozmen’s shift toward military contracts since taking leadership in 2023. Ozmen diverted $300M from Venture-Class spacecraft budgets to fund the Broomfield solar facility, prioritizing DoD relationships over commercial space stations.
This realignment manifests in three ways:
- Contract-driven hiring: 92% of 2026 openings link to specific military awards (SDA Tranche 2, Space Force NRO-G) rather than general headcount
- Turkey export freeze: Ozmen suspended all technology sharing with Turkey-based TAI Aerospace amid ITAR concerns
- Acquisition strategy: Sierra purchased Centennial-based satellite firm QEST Quantumsystems for $145M in 2025, absorbing their TS-cleared antenna engineers into Broomfield ops
Ozmen’s background in electronic warfare systems (formerly at L3Harris) explains the facility’s compartmentalized workspaces:
* Secure vault areas: 15% of floor space
* Unclassified solar wing assembly: 60%
* “Red zone” classified integration: 25% (requires COMSEC briefings for access)
Power Station Technology Center capabilities
The 68,000 sq ft Broomfield facility outpaces competitors in three metrics:
1. Rapid solar array deployment
Using modular jigs from decommissioned GE Aviation equipment, Sierra produces satellite solar wings in 8 days vs industry-standard 22 days. Their “SolarBlanket” design achieves:
- 345W/kg power density (17% higher than Boeing Spectrolab XTJ)
- 98.3% panel survival rate post-Micrometeoroid Impact Testing
- $8,400/kg production cost (NASA benchmarks allow $12,500/kg)
2. Classified payload integration
Broomfield’s 12 ISO-8 cleanrooms handle ESPA-ring compatible military payloads up to 500kg. Current projects include:
- TEMPEST-D jammers: Cylindrical phased arrays for GEO orbit satellites
- Mosaic Warfare transponders: Software-defined radios with 48-hour waveform reprogramming
- Counter-ASAT deception packages (details redacted per Space Systems Command guidelines)
3. Onsite environmental testing
Avoiding third-party delays, the facility features:
- Thermal cycling chambers (-185°C to +120°C)
- 12m × 8m × 8m anechoic chamber (validated to 110 GHz)
- Vibration tables replicating Falcon 9, Vulcan Centaur, and New Glenn launch profiles
Facility limitations
2025 Glassdoor reviews cite four persistent issues:
- ITAR documentation overload: Engineers spend 31% of time on compliance paperwork
- Supply chain gaps: 60-day lead times for Gallium Arsenide solar cells (sole-sourced from AASC)
- Overtime mandates: Production staff average 52hr/week during quarterly deliverable pushes
- Legacy equipment: 40% of CNC machines were retrofitted from Sierra Nevada Corporation’s 2018 Dream Chaser production line
