Finding computer science internships for high school students feels a lot like trying to find a unicorn in a basement. Most companies want juniors in college. They want people who have already taken Multivariable Calculus and survived a Data Structures & Algorithms course that made them cry. But here’s the thing: those internships do exist. You just have to know where the gatekeepers are hiding.
Honestly, most advice you'll find online is garbage. It’s written by people who haven't looked at a line of Python since 2012. If you want to spend your summer actually coding—not just getting coffee or filing papers—you need a strategy that goes beyond "apply on LinkedIn."
The Cold Hard Truth About High School Coding Roles
Let’s be real. A 16-year-old usually isn't going to be shipped off to fix a critical bug in Google’s search ranking algorithm. That’s just not how it works. Most computer science internships for high school students fall into two buckets: structured corporate "outreach" programs or "hustle-your-way-in" startups.
Structured programs, like the Microsoft High School Internship, are hyper-competitive. We’re talking thousands of applicants for a handful of spots. They look for more than just "I know Java." They want to see that you’ve used your skills for something—anything—outside of a classroom. Did you build a Discord bot that manages a server of 5,000 people? That’s gold. Did you get an A in AP Computer Science A? That’s... well, that’s just the bare minimum.
Then there’s the startup route. This is where things get interesting. Startups are messy. They have more work than people. If you can prove you can ship code, they often don’t care if you’re old enough to vote.
Where to Actually Find These Opportunities
You’ve probably heard of the big ones. NASA has the OSTEM program. It’s legendary. You get to work on actual flight software or data visualization projects. But it’s also a bureaucratic maze to apply for.
Then there is the SPARK Summer Internship Program. It specifically targets students in the Seattle area, connecting them with industry mentors. If you’re into the research side of things, look at the NIST (National Institute of Standards and Technology) Summer High School Intern Program (SHIP). It’s more "science" than "brogrammer," but it’s incredible for a resume.
Don't overlook local options.
Check your local university’s CS department. Professors are often desperate for someone to help clean up data or manage a basic web interface for their research. It might not be "Meta," but it’s a real computer science internship.
The "Secret" Strategy: Cold Emailing and Open Source
If you can't find a program, make one. This sounds scary. It is. But it works.
Find a mid-sized tech company in your city. Not a giant like Apple, and not a two-person garage shop. Look for companies with 50-200 employees. They have enough money to pay you $15-20 an hour, but they aren't so big that HR will automatically toss your resume because you don't have a degree.
Send a short email.
Keep it under five sentences.
Link your GitHub.
Specifically mention a feature of their product you like or a bug you noticed.
"Hi [Name], I’m a high school junior. I’ve been building React apps for two years. I love how [Company] handles [Feature]. Are you looking for a summer intern to help with your frontend backlog? Here’s my GitHub: [Link]."
That’s it. Most will ignore you. One might say yes.
GitHub is Your Real Resume
No one cares about your GPA in a tech interview. They care about your commits. If your GitHub is a ghost town, you aren't getting a computer science internship for high school students at a top-tier place.
You need a project that isn't a calculator or a "To-Do" list. Everyone has those. Build something that solves a weird, specific problem. I once knew a kid who built an automated script to alert him when his favorite brand of limited-edition sneakers dropped. He got an internship because he could explain how he handled the rate-limiting on the website.
Contribution to open source is another "cheat code." Find a library you use. Look at the "good first issue" tags on GitHub. Fix a typo in the documentation. Then fix a small bug. Now, you can say you’ve contributed to a project used by thousands of people.
Technical Skills: What Do You Actually Need?
Stop trying to learn 10 languages. It’s a waste of time. Pick one stack and get actually good at it.
- Web Dev: TypeScript, React, and maybe some Tailwind CSS.
- Data Science: Python, Pandas, and Jupyter Notebooks.
- Systems: C++ or Rust (if you're a glutton for punishment).
Most computer science internships for high school students involve web development or basic QA (Quality Assurance) testing. If you can write a test suite in Jest or Cypress, you are suddenly very valuable. Companies hate writing tests. If you offer to do it, they might just hire you on the spot.

The Soft Skills Everyone Ignores
Can you explain your code without sounding like a robot? That’s the "Vibe Check." In an interview, when they ask you to solve a problem, talk through your thought process. "I’m thinking of using a hash map here because I need $O(1)$ lookup time, but I’m worried about memory usage."
That sentence alone proves you know more than 90% of your peers. It shows you understand trade-offs.
Real Programs You Can Apply for Right Now
Here is a non-exhaustive, messy list of things that are actually real and reputable:
- Bank of America Student Leaders: It’s more "leadership" focused, but they have tech-adjacent roles in their non-profit placements.
- Air Force Research Laboratory (AFRL) Scholars Program: If you’re a US citizen, this is a massive opportunity to work on high-level tech.
- Google Computer Science Summer Institute (CSSI): Technically for graduating seniors heading into college, but keep it on your radar.
- The Simons Summer Research Program: Very heavy on the math and CS theory side at Stony Brook University.
Dealing with the "No"
You are going to get rejected. A lot.
The math is simple. If you apply to 50 places, 45 will ghost you, 4 will reject you after an automated test, and 1 might give you an interview. This isn't because you're bad at coding. It's because the legal departments at big companies are terrified of having minors on-site.
Don't take it personally. It’s a logistics game.
If you can't get an internship, do a "Pre-College" program or a high-end summer camp like Stanford High School Summer College or Carnegie Mellon’s Pre-College CS. They aren't internships—you pay them, they don't pay you—but they provide the network. And in tech, the network is basically everything.
Is it Worth the Stress?
Honestly? Sometimes no. If you spend your whole summer grinding LeetCode and stressing over computer science internships for high school students, you might burn out before you even get to college.
There is a lot of value in just building your own thing. Start an LLC. Build an app. Try to get 100 users. That "failed" startup of yours is often more impressive to a recruiter at a Tier-1 company than a summer spent clicking buttons for a local non-profit.
Actionable Steps to Take Today
Stop scrolling and do these four things.
First, fix your GitHub. Pin your best two projects. Make sure the README files actually explain what the project does and how to run it. If there’s no "how to install" section, the recruiter is moving on in three seconds.
Second, update your LinkedIn. You don't need a suit and tie photo. Just a clean headshot against a plain wall. List your skills. Connect with people who go to your school and are now in college. Ask them where they interned.
Third, target local. Use Google Maps. Type in "Software Company" or "Tech Startup" in your city. Go to their website. See if they have a "Careers" page. If they don't mention high schoolers, email them anyway. The worst they can do is not reply, and you're already in that position now.
Fourth, learn Git. Not just git commit and git push. Learn how to branch, how to handle a merge conflict, and how to open a Pull Request. If you show up on day one knowing how to use Git properly, your mentor will want to hug you.
Finding a role is a marathon. It’s frustrating. But getting that first "Software Engineering Intern" line on your resume while you're still in high school sets you up for the rest of your career. It makes getting that college internship at a FAANG company 10x easier.
Focus on the proof of work. Code speaks louder than a resume ever will.
