Security clearance note
Seal Beach is heavily classified. Most engineering roles require an active TS/SCI clearance or the ability to obtain one. Boeing will sponsor clearances for new hires, but the process adds 6-18 months to your start timeline. Having an existing clearance is a significant advantage.
### El Segundo — Millennium Space and Defense
Boeing acquired Millennium Space Systems in 2018. The El Segundo operation builds small and medium-class satellites for national security customers, including the **Space Development Agency (SDA) Tranche** programs.
| Detail | Info |
|--------|------|
| Address | El Segundo, CA (near LAX) |
| Employees | ~1,500 |
| Key programs | SDA transport and tracking satellites, responsive space |
| Specialties | Small satellite design, rapid prototyping, mission assurance |
| Clearance | Most roles require Secret or higher |
Millennium Space has a more startup-like culture than traditional Boeing sites. The team builds satellites faster and in higher volume than the legacy Boeing satellite division, which gives engineers exposure to full lifecycle work — design through integration and test — on compressed timelines.
### Long Beach — C-17 Sustainment
Boeing's Long Beach facility is the former McDonnell Douglas plant where C-17 Globemaster III production happened. Production ended in 2015, but the site now serves as the **C-17 sustainment center**, supporting the global fleet of 275+ aircraft.
| Detail | Info |
|--------|------|
| Address | 2401 E. Wardlow Rd, Long Beach, CA 90807 |
| Employees | ~3,000 |
| Key programs | C-17 sustainment, modifications, fleet support |
| Specialties | Structural engineering, avionics upgrades, logistics |
| Clearance | Some roles require Secret |
### Other CA locations
Boeing also maintains smaller offices in **San Jose** (autonomous systems), **Sylmar** (propulsion components), and various Southern California test facilities.
## Salary ranges with California locality
California Boeing salaries are adjusted upward for cost of living. Here's what to expect by role and experience level:
| Role | Level | CA Base Salary | National Avg for Comparison |
|------|-------|---------------|---------------------------|
| Mechanical Engineer | Entry (0-2 yr) | $95K–$120K | $80K–$100K |
| Mechanical Engineer | Senior (5-10 yr) | $140K–$185K | $120K–$160K |
| Systems Engineer | Mid (3-5 yr) | $125K–$160K | $110K–$140K |
| Software Engineer | Senior (5-10 yr) | $155K–$205K | $135K–$175K |
| Satellite Engineer | Mid (3-5 yr) | $130K–$170K | $115K–$150K |
| RF Engineer | Senior (5+ yr) | $150K–$195K | $130K–$170K |
| Program Manager | Senior (8+ yr) | $165K–$215K | $145K–$190K |
| Quality Engineer | Mid (3-5 yr) | $105K–$140K | $90K–$120K |
| Manufacturing Engineer | Entry (0-2 yr) | $85K–$110K | $72K–$95K |
| Technician (union) | Experienced | $70K–$95K | $55K–$80K |
California tax impact
California's state income tax tops out at 13.3%, the highest in the nation. A Boeing engineer earning $160K in Huntington Beach takes home roughly $8,000-$12,000 less per year than the same salary in Washington state (no income tax) or Texas. Factor this into your location decision — Boeing's WA sites offer comparable work without the state tax burden.
## Boeing benefits (same nationwide)
Boeing's benefits package is consistent across all U.S. locations:
- **401(k)**: Boeing contributes 75% match on the first 8% of pay (effective 6% company contribution), plus an automatic 4% employer contribution regardless of employee contribution. Total potential: **10% employer contribution**.
- **Health insurance**: Multiple plan options. Boeing picks up a large share of premiums.
- **Pension**: Boeing froze its defined-benefit pension in 2016 for new hires, replaced with increased 401(k) contributions.
- **Tuition assistance**: Up to **$25,000/year** for approved programs — one of the most generous in aerospace.
- **PTO**: 15-25 days depending on years of service, plus holidays.
- **Parental leave**: 12 weeks paid.
## Space programs driving CA hiring in 2026
Several active programs are creating openings at California Boeing sites:
**SLS Exploration Upper Stage (Huntington Beach)**: The larger, more capable upper stage for SLS Block 1B is in development. This drives hiring in propulsion, structures, avionics, and systems engineering. The Artemis IV mission, which will use the EUS for the first time, is targeted for the late 2020s.
**Starliner (Huntington Beach)**: After successful crewed flight tests, Starliner is ramping to operational ISS rotation missions. Manufacturing, mission ops, and integration technicians are in demand.
**SDA satellite production (El Segundo)**: The Space Development Agency's Proliferated Warfighter Space Architecture requires dozens of satellites delivered on aggressive timelines. Millennium Space is hiring across all engineering disciplines to meet production quotas.
**WGS follow-on (Seal Beach)**: The next generation of Wideband Global SATCOM satellites keeps Seal Beach staffed with satellite systems engineers and RF specialists.

## Is Boeing California worth it?
Working at Boeing in California gives you access to some of the most consequential space programs in the country — SLS, Starliner, and national security satellites. The salary premium partially offsets the high cost of living, and the programs themselves offer genuine technical depth.
The downsides: California's tax burden, housing costs in Orange County and the South Bay, and Boeing's well-documented organizational challenges (which are company-wide, not CA-specific). If you can handle the cost of living and want to work on hardware that flies, Boeing California is a strong option.
