What Does a Aerospace Engineer Do? Role Breakdown

Aerospace Engineer Job Description — Duties, Skills, Salary & Career Path

About 4,500 aerospace engineering positions open annually through 2034 according to the Bureau of Labor Statistics, driven by commercial space ventures, next-generation military platforms, and the push toward sustainable aviation fuels [1]. Aerospace Engineers design the aircraft, spacecraft, satellites, and missile systems that define both national security and commercial transportation — a scope that demands rigorous technical skill and an unflinching attention to safety margins.

Key Takeaways

• Aerospace Engineers design, develop, and test aircraft, spacecraft, satellites, and missiles.
• The median annual wage was $134,830 in May 2024, with the top 10% earning above $205,850 [1].
• A bachelor's degree in aerospace engineering or a closely related discipline is the standard entry requirement.
• Employment is projected to grow 6% from 2024 to 2034, faster than the average for all occupations [1].
• Engineers working on defense projects typically require a government security clearance.

What Does an Aerospace Engineer Do?

Aerospace Engineers apply principles of physics, materials science, and advanced mathematics — calculus, differential equations, linear algebra — to design vehicles and systems that operate in Earth's atmosphere or outer space [1]. The field splits into two primary branches: aeronautical engineering (aircraft, drones, helicopters) and astronautical engineering (rockets, satellites, space probes). In both branches, engineers run computational simulations, conduct wind-tunnel tests, analyze structural loads, and validate designs against rigorous safety and performance standards before a prototype ever leaves the ground.

Day-to-day work blends computer-based modeling with hands-on testing. An engineer might spend a morning refining computational fluid dynamics (CFD) models in ANSYS Fluent, then shift to reviewing stress-test results from a physical prototype in the afternoon. Collaboration across disciplines — avionics, propulsion, structures, thermal — is constant, since a single design decision can cascade through every subsystem [2].

Core Responsibilities

1. Design aircraft and spacecraft structures — Develop airframes, fuselages, wings, and payload fairings using CAD tools and finite element analysis.
2. Conduct aerodynamic analysis — Run CFD simulations and wind-tunnel tests to optimize lift-to-drag ratios, stability, and control surfaces.
3. Develop propulsion systems — Design and test jet engines, rocket motors, or electric propulsion systems for mission-specific performance envelopes.
4. Perform structural analysis — Calculate load paths, fatigue life, and failure modes under operational and extreme conditions.
5. Create and review technical specifications — Write engineering requirements documents that define performance, reliability, and safety criteria.
6. Prototype and test components — Build test articles, instrument them, and execute ground and flight test programs.
7. Analyze test data — Evaluate telemetry, sensor data, and test results to validate design models and identify anomalies.
8. Ensure regulatory compliance — Align designs with FAA, EASA, NASA, or DoD standards as applicable to the program.
9. Manage project timelines and budgets — Coordinate with program managers to keep engineering deliverables on schedule.
10. Collaborate across engineering disciplines — Work with avionics, thermal, and manufacturing engineers to integrate subsystems into cohesive platforms.
11. Investigate failures and anomalies — Lead root-cause analysis when components fail during testing or in-service operations.
12. Mentor junior engineers — Provide technical guidance and review work products from early-career team members.

Required Qualifications

• Education: Bachelor's degree in aerospace engineering, mechanical engineering, or a closely related field [1].
• Technical skills: Proficiency in CAD (CATIA, SolidWorks, NX), FEA (ANSYS, Nastran), and CFD software.
• Mathematics: Strong command of calculus, differential equations, trigonometry, and numerical methods [1].
• Problem-solving: Ability to diagnose complex system-level engineering problems under constraints.
• Communication: Clear written and oral communication for technical reports and cross-team reviews.
• Citizenship: U.S. citizenship and eligibility for security clearance for defense-related positions [1].

Preferred Qualifications

• Master's degree or Ph.D. in aerospace or mechanical engineering.
• Professional Engineer (PE) license.
• Experience with GD&T (Geometric Dimensioning and Tolerancing) and MIL-STD specifications.
• Familiarity with MBSE (Model-Based Systems Engineering) tools such as Cameo or DOORS.
• Background in composite materials and additive manufacturing.
• Prior work on FAA-certified or DoD-qualified programs.

Tools and Technologies

Work Environment

Aerospace Engineers typically split time between office-based design work and laboratory or test-facility environments [1]. Travel may be required for flight test campaigns, supplier reviews, or launch-site support. Most work full time; extended hours are common during critical design reviews, test campaigns, and program milestones. Engineers at defense contractors or government agencies may work in classified environments with additional access restrictions. The industry has a strong safety culture — design reviews, peer checks, and formal sign-off processes are deeply embedded in daily workflows [2].

Salary Range

The BLS reports the following for aerospace engineers as of May 2024 [1]:

Federal government positions and roles in guided-missile manufacturing tend to cluster at the higher end. Geographic premiums are significant in aerospace hubs such as Southern California (Northrop Grumman, Boeing, SpaceX), Seattle (Blue Origin, Boeing), Huntsville, AL (NASA Marshall, defense contractors), and the greater Washington, D.C. area [3].

Career Growth

Early-career engineers (0-3 years) focus on discipline-specific tasks under senior supervision. Mid-career professionals (4-10 years) take ownership of subsystems or lead small teams. Senior engineers (10+ years) become technical leads, chief engineers, or engineering fellows — roles that set architectural direction for entire programs. Management tracks lead to Engineering Director or VP of Engineering positions. Some engineers transition to systems engineering, technical program management, or venture-backed aerospace startups. The growing commercial space sector (SpaceX, Rocket Lab, Relativity Space) has widened the aperture of career options beyond traditional primes [4].
