Aerospace engineer salary at Boeing in 2026: pay levels, SPEEA rates, and location adjustments
Boeing's aerospace engineer salary in 2026 depends on three things: your level, your location, and whether you're in a SPEEA-represented bargaining unit. Boeing uses a six-tier technical ladder (L1 through L6) for individual contributors, and the Society of Professional Engineering Employees in Aerospace (SPEEA) negotiates pay minimums for roughly 17,000 engineers in the Puget Sound region. That union layer makes Boeing unique among major aerospace employers.
Here's what the numbers actually look like across levels, sites, and divisions — and how Boeing stacks up against other employers hiring aerospace engineers.
Boeing aerospace engineer salary by level
Boeing's leveling system maps loosely to experience, though internal promotions and external hire calibrations can shift things:
These ranges come from Glassdoor, Levels.fyi, and SPEEA-published salary data. The median aerospace engineer salary at Boeing sits around $118K — skewed toward L2/L3 where most of the workforce lands.
L1 to L2 promotion takes 2-3 years. L2 to L3 takes another 3-4 years. L4 and above require demonstrated leadership on programs, and L5/L6 are reserved for engineers with company-wide or industry-wide technical influence. Boeing Fellows (L6) are rare — maybe 100 across the entire company.
The SPEEA factor
Boeing is the only major aerospace company where engineers have union representation. SPEEA (International Federation of Professional and Technical Engineers, Local 2001) covers engineers and technical workers primarily in Washington state and a smaller unit in Wichita.
What SPEEA means for your pay:
- Salary minimums by level — SPEEA contracts set floor rates for each level. An L1 in the Puget Sound unit can't be paid below the contract minimum regardless of what Boeing might offer otherwise
- Annual general wage increase — The 2024-2028 SPEEA contract includes yearly raises of 4-5%, applied across the board
- Overtime protections — SPEEA members earn overtime pay (1.5x) after 40 hours/week. Non-SPEEA Boeing engineers are salaried exempt
- Layoff protections — Reductions in force follow seniority-based rules under SPEEA contracts, giving longer-tenured engineers more security
Boeing engineers in Washington state (Everett, Renton, Seattle, Auburn, Kent) fall under SPEEA. Engineers at non-SPEEA sites (St. Louis, Huntsville, El Segundo, Oklahoma City, Charleston) are at-will employees without union minimums or overtime protections. Same company, different rules. A move from Everett to Huntsville means losing SPEEA coverage even if your title stays the same.
Boeing aerospace engineer salary by location
Location changes your take-home pay significantly — both through Boeing's geographic salary bands and through state tax differences:
| Location | Key Programs | Salary Adjustment | State Income Tax |
|---|---|---|---|
| Everett / Seattle, WA | 787, 777X, defense avionics | Highest band (SPEEA) | None |
| El Segundo, CA | Satellites, Millennium Space Systems | +5-10% CA premium | 9.3-13.3% |
| St. Louis, MO | F-15, F/A-18, T-7A, MQ-25 | Standard | 4.8% |
| Huntsville, AL | SLS, Space Launch System | -5% below standard | 5% |
| Oklahoma City, OK | KC-46, B-52 modernization | -5-10% below standard | 4.75% |
| Charleston, SC | 787 production | Standard | 6.5% |
| Kennedy Space Center, FL | SLS launch ops, Starliner | Standard | None |
Washington state is Boeing's best deal for engineers: SPEEA minimums push salaries higher, and Washington has no state income tax. An L3 engineer earning $130K in Everett keeps roughly $10K-$15K more per year than the same salary in El Segundo after California taxes.
The El Segundo campus, home to Millennium Space Systems (a Boeing subsidiary), tends to pay at the higher end of Boeing's bands because it competes directly with SpaceX Hawthorne and Northrop Grumman's nearby facilities for the same talent pool.
Boeing space division salary
Boeing's space work splits across two main entities:
Boeing Defense & Space handles SLS (Space Launch System), Starliner crew vehicle, and satellite communications. These programs are based in Huntsville, Kennedy Space Center, and El Segundo. Salaries for aerospace engineers on SLS programs run $100K-$165K at the L2-L4 range.
Millennium Space Systems builds small satellites for military customers. Based in El Segundo, Millennium typically pays a 10-15% premium over Boeing's general bands because the work requires cleared engineers in a high-cost market. Deputy Chief Engineer roles at Millennium reach $211K-$310K per internal data.

Total compensation beyond base
The aerospace engineer salary at Boeing doesn't tell the full story. Total comp includes:
401(k) — Boeing contributes 10% combined: a dollar-for-dollar match on the first 8% you contribute, plus a 2% automatic company contribution. On a $130K salary, that's $13K/year in retirement contributions from Boeing alone.
Annual incentive — Variable bonus tied to company performance, typically 5-10% of base salary. In years where Boeing misses targets (which has happened), this can drop to zero.
SPEEA overtime — For union-represented engineers working overtime-eligible schedules, overtime at 1.5x can add $10K-$25K annually depending on program demands. This is money that salaried-exempt engineers at SpaceX or Lockheed don't get.
Tuition reimbursement — Up to $15,000/year for approved degree programs. Many Boeing engineers pursue master's degrees at the University of Washington on Boeing's tab while working full-time.
Healthcare — Standard corporate plans with Boeing contributing roughly 75% of premiums. Below-average compared to tech companies, comparable to other defense primes.
How Boeing compares to other employers
| Factor | Boeing | SpaceX | Lockheed Martin | Northrop Grumman |
|---|---|---|---|---|
| Entry salary (L1) | $85K-$100K | $95K-$130K | $72K-$95K | $79K-$119K |
| Mid salary (L3) | $110K-$145K | $140K-$180K | $110K-$155K | $118K-$176K |
| Senior salary (L4-L5) | $150K-$210K | $170K-$230K | $135K-$220K | $144K-$240K |
| 401(k) | 10% total | Standard match | 10% total | 6% match |
| Union | Yes (SPEEA) | No | No | No |
| Avg hours/week | 40-45 | 55-65 | 40-45 | 40-45 |
| 9/80 schedule | Some sites | No | Yes (most) | Yes (most) |
Boeing's base salary is competitive with Lockheed Martin and slightly below Northrop Grumman. SpaceX pays more in base and offers equity, but Boeing engineers work 15-25 fewer hours per week and have union protections that don't exist elsewhere.
The real Boeing advantage is the combination of SPEEA overtime eligibility, 10% 401(k) contribution, and reasonable hours. An L3 aerospace engineer at Boeing making $125K base who works 400 hours of overtime in a year at 1.5x adds roughly $36K to their income — pushing total comp well above $170K without the 60-hour-week grind.
An L3 Boeing engineer in Seattle earning $130K for 42 hours/week earns roughly $60/hour. A SpaceX engineer earning $170K for 60 hours/week earns roughly $55/hour. Boeing pays less per year but more per hour — and SPEEA members get paid for those extra hours instead of donating them.
Boeing's challenges and how they affect pay
Boeing's well-documented quality and production issues in commercial aviation haven't directly reduced engineering salaries, but they affect compensation in indirect ways. Program delays mean fewer bonuses (the annual incentive ties to company metrics). Layoff rounds in 2024 and 2025 hit thousands of employees. Morale scores on Glassdoor sit at 3.7/5 — below Lockheed (4.0) and Northrop (4.0).
For aerospace engineers focused on space, Boeing's SLS delays and Starliner setbacks have similar morale effects. The upside: SLS is funded through at least Artemis IV, meaning job stability on the program is decent through the late 2020s. And Millennium Space Systems operates as a semi-independent unit with a startup culture distinct from Boeing's corporate bureaucracy.
Frequently asked questions
What is the starting salary for an aerospace engineer at Boeing?
Entry-level aerospace engineers (L1) at Boeing earn $85K-$100K base salary, depending on location and degree level. BSAE holders typically start at $85K-$92K, while MSAE holders can start at $92K-$100K. SPEEA-represented sites in Washington state have contractual minimums that guarantee rates at or above these ranges.
Does Boeing pay overtime to engineers?
At SPEEA sites (Washington state, parts of Wichita), Boeing engineers are overtime-eligible and earn 1.5x their hourly rate after 40 hours per week. At non-SPEEA sites, most engineers are salaried exempt and do not receive overtime pay. This is a major financial difference — overtime can add $10K-$25K annually.
How does Boeing's aerospace engineer salary compare to SpaceX?
SpaceX pays 15-25% more in base salary and offers equity. Boeing pays less per year but more per hour due to shorter work weeks. Boeing's 10% 401(k) contribution and SPEEA overtime eligibility narrow the total compensation gap significantly. At the L3 level, Boeing total comp of $155K-$175K (including overtime and 401k) approaches SpaceX's $170K-$200K (including equity) — but with 15-20 fewer hours worked per week.
Which Boeing location pays aerospace engineers the most?
Washington state (Everett, Seattle, Kent) offers the highest base salary due to SPEEA contract minimums and the Seattle labor market. El Segundo, CA pays similar base rates but California's 9.3-13.3% state income tax reduces take-home pay. For purchasing power, Washington wins: high salaries, no state income tax, and union protections.
