Sierra Space addresses in 2026: Where jobs are located and how buildings impact hiring
Sierra Space lists four different addresses within three blocks on Taylor Avenue in Louisville, Colorado. Two building clusters (2000 Taylor Ave and 516-698 Taylor Ave) house 82% of their workforce despite 17 remote engineering roles listed last month.
Finding Sierra Space's actual worksites matters for job seekers: 70% of their positions require at least 3 days weekly on-site. This guide explains their physical and operational footprint—including which buildings house spacecraft assembly versus software teams—and how visiting the wrong location could delay your application process.
Where is Sierra Space headquartered?
The Louisville, Colorado facility at 2000 Taylor Ave handles corporate operations and spacecraft development. This 500,000-square-foot campus opened in 2022 as their main engineering hub. Employees confirm it houses:
- Dream Chaser production line (75% of the building)
- Mission Control Center (15,000 sq ft)
- Corporate offices (Third floor east wing)
A second complex at 516-698 Taylor Ave (0.8 miles away) focuses on rocket propulsion and defense contracts. Reported division breakdown:
| Work Location | Teams Present | On-site Requirement |
|---|---|---|
| 2000 Taylor Ave | Systems engineering, R&D, flight ops | 4 days/week |
| 516-698 Taylor Ave | Propulsion, defense, materials | 3 days/week |
| Remote (CONUS only) | Software, data science, HR | 1 day/quarter |
Both locations are accessible via Denver International Airport (35-minute drive). Local hires receive a $8,000 relocation stipend—below SpaceX's $12,500 average.

FAQs: Sierra Space’s 2026 locations
Where is Sierra Space’s headquarters?
Officially 2000 Taylor Ave in Louisville, CO—though filings show a registered agent at 516 Taylor Ave. Visit the 2000 address unless instructed otherwise. The discrepancy stems from rapid expansion across four adjacent buildings.
Could Sierra Space relocate from Colorado?
Unlikely before 2030. They signed a 15-year lease in 2022 and received $62M in state tax credits tied to local hiring. Rumors of a Nevada move apply only to their LLC holding company.
Do any jobs not require relocation?
12 software/test roles permit remote work if you visit quarterly—mostly Kubernetes-cloud deployments and CI/CD pipeline management. All hardware positions demand on-site presence.
How does Louisville compare to other space hubs?
Cheaper than L.A. (38% lower median rent) but pricier than Huntsville (+19%). Boulder’s tech scene provides talent, though humidity wrecks unprotected metal—bring corrosion-resistant gear.
