Aerospace Engineering Internships in 2026: How to Apply

Landing an aerospace engineering internship requires early preparation, a clear target discipline, and a portfolio that demonstrates direct technical work on hardware or flight software. Across space, defense, and aviation companies, employers hire interns for specialized tracks including propulsion, structural analysis, avionics, systems integration, and guidance, navigation, and control (GNC).

With 3,893 open roles across the industry, companies are recruiting for immediate openings in 2026 as well as planning lead times for 2027 programs. Understanding pay rates, job responsibilities, and application timelines helps you submit competitive applications.

What Aerospace Engineering Internships Pay

Compensation for aerospace engineering interns varies by role, geographic region, and corporate structure. Hourly rates in the United States generally range between $28 and $55 per hour for engineering majors, while salaried internships offer annual equivalents up to $88,000.

High-cost coastal markets like San Francisco and Los Angeles feature some of the highest hourly compensation. For instance, Astro Mechanica lists pay between $40 and $55 per hour in San Francisco for roles in structures, propulsion, and electrical systems. Apex Space in Los Angeles pays $45 per hour for mission integration engineers, while Vast offers $35 to $42 per hour in Long Beach.

Other US regional locations offer competitive pay scaled to local markets. Loft Orbital pays $30 per hour in Golden, Colorado, while Gravitics offers $28 to $35 per hour in the Greater Seattle Area. Large defense contractors like RTX post annual salary ranges, paying between $42,000 and $88,000 per year for mechanical engineering interns in El Segundo, California.

European internship compensation structure typically follows monthly stipends. In France, HyLight offers stipends between €800 and €2,500 per month depending on the technical domain and intern qualifications.

Technical Disciplines and Internship Roles

Aerospace companies rarely hire for generalists at the intern level. Most postings target specific engineering sub-disciplines.

Propulsion Engineering

Propulsion interns focus on liquid rocket engines, air-breathing propulsion, or electric thrusters. The work involves thermal analysis, fluid dynamics modeling, dynamic pressure testing, and physical hardware assembly. Employers look for coursework in thermodynamics, compressible flow, and heat transfer. Open positions include the Propulsion Engineering Intern at Astro Mechanica and the 12 months internship - Propulsion Test Engineer (m/f/d) at Isar Aerospace in Kiruna, Sweden.

Structures and Mechanical Design

Mechanical design interns build computer-aided design (CAD) models, run finite element analysis (FEA), and conduct structural load testing. You work directly with primary structures, secondary brackets, payload fairings, or mechanical ground support equipment. Active roles include the Airframe/Structures Engineering Intern at Astro Mechanica, the Mechanical/Aerospace Engineering Intern (Summer 2027) at Axiom Space, and the Mechanical Engineering Internship at HyLight.

Avionics and Electrical Engineering

Avionics internships center on wire harness design, circuit board layout, power distribution, and microcontroller integration for launch vehicles or spacecraft. Candidates need familiarity with schematic capture tools, PCB design software, and laboratory equipment like oscilloscopes and logic analyzers. Employers hiring in this domain include Inversion Space for their Avionics Mechanical Engineer - Summer Internship 2027 position, alongside the Electrical/Avionics Engineering Intern at Astro Mechanica.

Systems Engineering and GNC

Systems and GNC interns focus on trajectory simulation, control system design, mission operations, and sub-system requirements trace. Positions like the GNC Drone Engineer Internship at HyLight, the Summer 2027 - Systems Engineering Internship at CesiumAstro, and the Mission Integration Engineer Internship (Spring or Summer 2027) at Apex Space emphasize MATLAB, Simulink, Python modeling, and hardware-in-the-loop testing.

How to Build a Strong Application

Aerospace hiring managers prioritize demonstrated technical execution over high grade point averages alone. To stand out when submitting applications:

1. Highlight Project Team Experience: Active involvement in student engineering organizations—such as Formula SAE, Design Build Fly, liquid rocketry teams, or CubeSat projects—provides proof of hardware lifecycle experience.
2. Include Technical Portfolios: Attach a concise digital portfolio or PDF link showing CAD renders, dynamic stress analysis plots, code samples, circuit layouts, or physical hardware builds.
3. Tailor Skills to Specific Sub-Domains: Align resume bullet points directly with toolsets mentioned in job descriptions, such as SolidWorks, ANSYS, MATLAB, Python, C++, or Altium Designer.
4. Track Early Recruitment Cycles: Major aerospace organizations open applications six to nine months ahead of start dates. Summer 2027 internship postings are actively recruiting current undergraduate and graduate students.
