SpaceX jobs in McGregor Texas in 2026: the rocket engine proving ground
Every engine that powers a Falcon 9, every Raptor destined for Starship, and every Draco thruster on a Dragon capsule passes through the same 4,000-acre facility in rural Central Texas before it ever flies. SpaceX's McGregor Rocket Development Facility is where engines are tested to destruction or certified for flight. The facility runs hot-fire tests so frequently that the local cattle have stopped flinching at the sound. If you want a job where the core metric is whether hardware survives a controlled explosion, McGregor is the place.
McGregor has grown from a small test operation when SpaceX acquired the former Beal Aerospace site in 2003 to a full-scale engine testing campus with multiple test stands, a propellant farm, and an expanding workforce. The headcount has increased from roughly 500 in 2024 to an estimated 600 in 2026, driven by the ramp in Raptor 3 production and the need for faster engine acceptance testing to support Starship's launch cadence.
The testing operation: what actually happens here
McGregor is a test facility, not a manufacturing plant. Engines and components arrive from other SpaceX locations, get bolted to test stands, and are subjected to controlled firings that validate their performance before they fly.
Raptor engine testing dominates the workload. Each Raptor engine undergoes acceptance testing: a series of firings at various power levels and durations that verify combustion stability, turbopump performance, thrust vector control, and thermal margins. With Starship requiring 33 Raptor engines on the Super Heavy booster and 6 on the upper stage, and SpaceX targeting multiple flights per year, the acceptance test throughput must handle hundreds of engines annually.
Merlin engine testing continues for the Falcon 9 program. Every Merlin 1D (sea-level and vacuum variants) is acceptance-tested at McGregor before being shipped to Hawthorne for vehicle integration.
Draco and SuperDraco thruster testing supports the Dragon capsule program. These smaller engines power the capsule's orbital maneuvering and launch escape systems.
Development testing is where new engine variants are characterized. When SpaceX designed the Raptor 3 (a major redesign with simplified architecture and reduced part count), the development test series ran at McGregor for months, pushing engines through off-nominal conditions to map the performance envelope.
Component testing targets individual subsystems: turbopumps, injectors, valves, and ignition systems. These tests isolate specific components to verify performance before they are integrated into complete engines.
McGregor operates multiple test stands configured for different engine types and test objectives. The facility has expanded its stand count as Raptor production has scaled, with new stands built specifically for Raptor 3 acceptance testing. During peak operations, multiple stands fire simultaneously on different engines. The sound carries for miles, and the rocket exhaust plumes are visible from Highway 84.
Roles at McGregor and salary ranges
McGregor jobs are focused on testing, instrumentation, data analysis, and facility operations. The role mix is narrower than Hawthorne or Starbase but deeply specialized.
| Role | Salary / hourly range | What you do |
|---|---|---|
| Test Engineer | $92K–$140K | Plan and execute engine test campaigns, analyze performance data, write test reports |
| Propulsion Engineer | $95K–$145K | Support development testing, characterize engine performance, work with design teams |
| Instrumentation Engineer | $88K–$125K | Design sensor configurations, calibrate measurement systems, ensure data quality |
| Data Acquisition Engineer | $88K–$125K | Manage DAQ hardware/software, process telemetry, build analysis tools |
| Test Technician | $22–$34/hr | Install engines on stands, connect propellant and instrumentation lines, operate ground equipment |
| Instrumentation Technician | $24–$36/hr | Install sensors, thermocouples, strain gauges; maintain calibration standards |
| Facilities Engineer | $82K–$120K | Maintain propellant systems, high-pressure gas, cryogenic infrastructure |
| Safety Engineer | $88K–$130K | Hazard analysis, safety procedures, emergency response for hot-fire operations |
| NDE Technician | $26–$40/hr | Non-destructive examination of engines and hardware post-test |
| Controls Engineer | $90K–$135K | PLC programming, test stand automation, control system design |
Test engineers are the most in-demand role at McGregor. A test engineer owns the test campaign from planning through data review. During a hot-fire test, the test engineer monitors real-time engine parameters, makes go/no-go calls, and shuts down the test if something looks wrong. After the test, they analyze the data against predicted performance and either certify the engine for flight or flag issues for investigation.
This role requires a combination of propulsion fundamentals, data analysis skills, and the composure to make decisions in real time when millions of dollars of hardware are on the line.
McGregor has one of the strongest internal promotion cultures in SpaceX. Test technicians who demonstrate strong technical judgment, analytical thinking, and problem-solving skills regularly transition into engineering roles. SpaceX values demonstrated ability over credentials, and a technician who has hands-on experience with engine testing has a practical knowledge base that is difficult to replicate in a classroom. If you are a technician looking to grow into engineering, McGregor is a good bet.
Cost of living: the McGregor financial advantage
The single biggest reason McGregor attracts and retains talent is the cost of living. Central Texas is dramatically cheaper than any other SpaceX location, and the combination of competitive salaries with low expenses means McGregor employees can accumulate savings faster than their peers elsewhere.
| Expense | Waco / McGregor area | Hawthorne, CA | Redmond, WA | Cape Canaveral, FL |
|---|---|---|---|---|
| Median home price | $225,000 | $850,000+ | $750,000 | $365,000 |
| 1BR apartment | $800–$1,100/mo | $2,200–$2,800/mo | $2,000–$2,500/mo | $1,300–$1,700/mo |
| State income tax | 0% | 9.3–13.3% | 0% | 0% |
| Groceries (monthly) | $340 | $550 | $480 | $380 |
A test engineer earning $115,000 at McGregor with zero state income tax, a $1,500/month mortgage, and low daily expenses has more disposable income than an engineer making $155,000 in Hawthorne paying California taxes and $3,000/month rent. Add SpaceX RSUs on top, and the financial picture at McGregor is genuinely attractive.
Where people live
Waco (20 minutes north of McGregor) is where most SpaceX employees live. Population around 140,000. Waco has grown significantly in the last decade: restaurants, breweries, a riverwalk, Baylor University, and the Magnolia Market development. It is not a major city, but it has enough amenities for comfortable daily life.
McGregor itself is a small town of about 5,000 people. A few restaurants, a grocery store, and a small-town character. Some employees live here for the extremely short commute (5-10 minutes to the facility).
Temple / Belton (30 minutes southeast) offer affordable housing near Belton Lake. Outdoor recreation access is the draw.
Hewitt / Woodway (suburban Waco) are residential communities popular with families. Good schools, safe neighborhoods, 20-25 minute commute.
McGregor is rural. The nearest major airport is Austin-Bergstrom (90 minutes south) or DFW (100 minutes north). The nearest city with a full range of dining, entertainment, and shopping is Austin. If you need urban energy to be happy, McGregor will feel isolating. If you are comfortable with small-town life and save money while doing meaningful work, it is a strong option. Many McGregor employees are young engineers who live frugally and build significant savings in their first few years.
Work schedule and shift structure
Engine testing does not follow a 9-to-5 schedule. Test campaigns run around the clock, and the McGregor workforce operates in shifts.
- Day shift: 6 AM to 6 PM (12-hour shifts during campaigns)
- Night shift: 6 PM to 6 AM
- Standard weeks: Engineers typically work 50-60 hours
- Campaign surges: During critical testing (Raptor 3 qualification, new engine variant characterization), hours stretch further
- Between campaigns: Relative calm, but the increasing test cadence means quiet periods are shortening
Test engineers and technicians rotate through day and night shifts. The assignment depends on when your engine test is scheduled. If the test window opens at 2 AM, you are on the stand at 2 AM.
Raptor 3 and why McGregor matters more than ever
Starship's success depends on Raptor 3 engines, and every Raptor 3 must pass through McGregor for acceptance testing. The numbers tell the story:
- 33 Raptor engines per Super Heavy booster
- 6 Raptor engines per Starship upper stage
- 39 engines per Starship stack
- Multiple Starship flights planned per year
- Goal: hundreds of Raptor engines per year
This engine production rate is unprecedented in rocket history. McGregor must match this rate with acceptance testing throughput. That means more test stands, more test engineers, more technicians, and faster turnaround between tests. The facility is investing in automation and parallel testing capabilities to keep up.
The implication for job seekers: McGregor is hiring and will continue to hire. The demand for test engineers and test technicians will grow in proportion to Raptor production.
McGregor compared to other SpaceX locations
If you are deciding between McGregor and another SpaceX site, the comparison comes down to what kind of work you want and what lifestyle you prefer.
| Factor | McGregor | Hawthorne | Starbase | Cape Canaveral |
|---|---|---|---|---|
| Primary work | Engine testing | Design + manufacturing | Starship production + launch | Launch operations |
| Cost of living | Very low | Very high | Low | Moderate |
| State income tax | 0% | 9.3-13.3% | 0% | 0% |
| Lifestyle | Rural small-town | Urban LA | Border town | Beach / Space Coast |
| Team size | ~600 | ~5,000+ | ~3,000+ | ~800 |
McGregor is the clear winner on cost of living and take-home pay relative to salary. An engineer making $115K at McGregor has more purchasing power than one making $150K at Hawthorne. The tradeoff is the rural setting: if you want urban amenities, McGregor will feel limiting.
