Where to Find Aerospace Internships: 5 Best Sites (2026)

Most lists of internship sites are the same twelve names in a different order, written by somebody who has never looked for a job in this industry. Aerospace has quirks that make general advice actively misleading. A large share of roles are restricted by export control rules. The application windows open nine months early and close on a rolling basis. And some of the best employers post exclusively on a federal system that no careers listicle ever mentions.

So this is five, not twelve, ranked by how much use they actually are if you want to work on hardware that flies. I run one of them, which you should factor into how you read the first entry, though the reasoning behind its placement is stated plainly enough that you can judge it yourself.

Measured on sector fit rather than size. The general platforms are far larger and win on things this table does not measure, which the entries below set out.

1. Internships.space

Best for: seeing everything in the sector in one place, without the noise.

The argument for a niche board over a general one is structural rather than promotional. A general aggregator indexes millions of postings across every industry, so its ranking has to be generic, and a search for "aerospace internship" on one of those sites returns a mix of genuine engineering roles, unrelated jobs at companies with "aerospace" in the name, staffing agency reposts and expired listings. The filtering problem is yours to solve.

A board that only covers aerospace, defense and deep tech solves it before you arrive. Listings are categorised by discipline rather than by keyword match, which matters when propulsion, avionics, GNC, structures and test are all separate career tracks that a general search engine treats as one blob. We tag eligibility where the employer states it, so you can filter out roles requiring citizenship or a clearance before spending an evening on an application rather than after. And we show pay ranges wherever they are published, which most boards strip out.

The coverage also reaches the tier of employer that general sites miss almost entirely: the suppliers, component manufacturers, test houses, ground segment companies and defence startups that do not run large recruiting operations and never rank for anything. That tier is where the realistic odds are, and it is close to invisible on the big platforms.

[CONFIRM: insert your live listing count and the number of employers covered. A specific number here is worth more than any adjective, and reviewers of this post will look for one.]

That is why a specialist board leads on every criterion in the table above. Each one is a consequence of covering a single sector rather than all of them: you cannot categorise by propulsion, GNC and structures if you also have to categorise dentistry, and you cannot tag clearance requirements if most of your listings have none.

Weakness worth stating: a niche board will never match the raw volume of a general aggregator, and if you want to widen into adjacent engineering you will need one of the others too.

2. Handshake

Best for: verified postings aimed specifically at students, and the lowest friction application path.

Handshake works through university partnerships rather than open registration, which is the source of both its strengths. The platform works with more than 1,400 higher education institutions and over 750,000 employers, and public reporting has described it as serving roughly 20 million students and alumni.

Because access runs through your school, every posting is aimed at students by design. You are not filtering senior engineering roles out of your results, and you are not competing with career changers. Employers can also restrict postings to particular schools or majors, which sounds limiting but works in your favour when your university is on the list.

The catch is that Handshake shows you what employers chose to push to campus, which skews toward organisations with established university recruiting programmes. Large primes are well represented. A twelve person satellite startup usually is not.

How to use it properly: set up saved searches with alerts rather than browsing, and check the events tab as carefully as the jobs tab, since employer information sessions and virtual fairs are where recruiters flag names before applications are reviewed.

3. USAJOBS

Best for: the highest value roles that appear nowhere else.

This is the one that belongs on every list of this kind and appears on almost none of them. Federal aerospace research is enormous, and the internships attached to it are posted through the government's own system rather than through any commercial platform.

NASA's Pathways programme runs here rather than through the STEM Gateway that handles its other internships, and Pathways interns rotate through assignments and can convert directly into full time civil service roles. The same system carries student roles at the Air Force Research Laboratory, the Naval Research Laboratory, the Army labs and the FAA. These are competitive, but the applicant pool is a fraction of what a SpaceX posting attracts, largely because students do not know the postings exist.

Two pieces of mechanical knowledge make this site usable. The first is that Pathways vacancies are listed as "Student Trainee" roles, so searching "intern" will miss most of them. The second is that the windows are brutally short. One NASA centre's Pathways announcements ran from 1 February to 5 February, which is five days. If you are not running a saved search with email alerts you will simply never see them open.

Weakness worth stating: federal applications are genuinely tedious, the resume format is unlike anything else you will write, and everything here requires United States citizenship.

4. LinkedIn

Best for: finding the human being attached to the posting.

As a job board, LinkedIn is mediocre for this sector. Its aerospace internship results are heavily duplicated, frequently stale, and its "easy apply" pathway routes you into a pile that hiring managers rarely read directly.

As a research tool it is close to unmatched, and that is the reason it earns a place. You can find the engineers on the team you applied to, see which universities a company actually recruits from, identify alumni from your own school who interned there last summer, and read what people say about the work. A short, specific message to somebody who did the internship two years ago has a much better response rate than students expect, because almost nobody sends one.

How to use it properly: treat the job tab as a source of leads rather than an application channel. When you find a role, apply on the company's own site, then use LinkedIn to find one person on the team and ask them a real question about the work.

5. Indeed

Best for: catching the smaller employers who post nowhere else.

Indeed's ranking here reflects signal quality rather than size, since by volume it is the largest of the five. The problem for this sector is that volume brings staffing agencies, duplicated listings, expired postings and roles mislabelled as internships.

What it is genuinely good for is the long tail. A machine shop in Torrance doing composite layup for satellite structures, a test house near Huntsville, a fifteen person avionics firm, all of these are far more likely to post on Indeed than to run a campus recruiting programme. That tier is where a determined student with a modest resume actually gets hired, and it is worth wading through the noise to reach.

How to use it properly: search by employer type and location rather than by the word aerospace. Terms like "composites technician intern", "test engineering intern" and "machine shop intern" plus a cluster city will surface things that a sector keyword never will.

The sixth place, which is not a website

Company career pages remain the most reliable source in this industry and they are not a platform, so they cannot be ranked. Every one of the five above is a discovery layer. Once you know which thirty employers you care about, checking their own pages on the first Monday of each month from August through February will beat any alert system, because postings appear there first and rolling review means the queue position you get on day one is worth more than a better application on day thirty.

Use the boards to find out who exists. Use the career pages to actually apply.

Frequently asked questions

What is the best website for aerospace internships?

For sector coverage and filtering, a specialist board beats a general aggregator, because aerospace roles are split across disciplines and eligibility rules that keyword search handles badly. Most students should run a specialist board alongside Handshake and USAJOBS rather than relying on any single source.

Is Handshake or LinkedIn better for internships?

Handshake for finding and applying, since every posting is aimed at students and the process is built for people with no work history. LinkedIn for researching the company and reaching the people on the team once you have found a role elsewhere.

Where does NASA post its internships?

In two different places. OSTEM internships go through the NASA STEM Gateway, while Pathways internships are posted on USAJOBS, usually titled as Student Trainee roles rather than internships.

How many internships should I apply to?

Twenty five to forty across a range of employer sizes is a realistic target for competitive programmes, spread across the sources above rather than concentrated on the famous names.

Are aerospace internships posted on Indeed legitimate?

Many are, particularly from smaller suppliers, but the platform carries more duplicates, staffing agency reposts and expired listings than the others. Verify anything promising against the company's own careers page before applying.

Do I need to check more than one site?

Yes. Federal roles appear only on USAJOBS, campus targeted roles appear only on Handshake, and small suppliers frequently appear only on general aggregators or their own sites. No single source covers the sector.

Start with aerospace and space internships, defense and national security roles or deep tech internships, filtered by discipline, location and eligibility.
