Your Step-by-Step Guide to Applying for the Rust Project's Outreachy Internship

Introduction

Are you passionate about Rust and looking for a paid opportunity to contribute to open source? The Rust Project is participating in Outreachy, a program that offers internships to people from understated backgrounds in tech. This guide walks you through the complete process—from understanding what Outreachy is to successfully applying and landing an internship with the Rust Project. You'll also discover tips to make your application shine. Let's dive in!

What You Need

Before you start, ensure you have the following:

Basic knowledge of Rust – You should be comfortable reading and writing Rust code. Familiarity with the compiler and ecosystem is a plus.
Time commitment – The application process includes a contribution period that requires several weeks of active work, plus you'll need availability for the internship itself (12 weeks, full-time or part-time).
An interest in open source collaboration – You'll work with mentors and the community on real projects.
Eligibility for Outreachy – Check the official Outreachy website to see if you meet their criteria (e.g., underrepresentation, systemic bias, or discrimination in the tech industry where you live).

Step-by-Step Guide

Step 1: Understand Outreachy and Its Differences from Other Programs

Outreachy is similar to Google Summer of Code (GSoC) but with key differences that shape your application strategy:

Application order: You first apply to the overall Outreachy program, then to specific projects (like Rust). In GSoC, you apply directly to a project.
Contributions required: GSoC applicants may optionally make contributions before applying, but Outreachy requires a dedicated contribution period. You must demonstrate your ability to work with the community.
Funding: In Outreachy, the community (i.e., the Rust Project) covers your stipend, whereas Google funds GSoC.
Cohorts: Outreachy runs two cycles per year: May–August and December–March. Rust is participating in the May 2026 cohort.

Knowing these distinctions helps you plan your timeline and focus on building genuine contributions.

Step 2: Prepare for the Contribution Period

Outreachy requires you to contribute to the community before you can apply to a specific project. Here's how to prepare:

Join the Rust community channels – Introduce yourself on the Rust Internals forum or the Zulip chat. Follow project announcements related to Outreachy.
Identify potential project areas – The Rust Project selected four mentoring projects for the May 2026 cohort (details below). Study their descriptions and reach out to mentors with questions.
Set up your development environment – Clone the Rust repository or relevant tool (like a-mir-formality) and ensure you can build and test changes.
Start small – Fix a bug, improve documentation, or run a test. The goal is to show you can collaborate effectively.

Step 3: Apply to the Outreachy Program as a Whole

Once the application period opens (check the Outreachy website for exact dates), submit your initial application. This step is about proving you meet Outreachy's eligibility criteria. You'll provide:

Personal information and background.
Evidence of underrepresentation or discrimination in your local tech industry.
A statement about your motivation.

After your application is accepted, you become eligible to apply to specific communities like Rust.

Step 4: Apply to the Rust Project

With your Outreachy approval in hand, you can now apply to the Rust Project. This step involves:

Submitting a detailed application – Include your background, the project you're interested in, your proposed timeline, and how you plan to tackle the work. Mention any contributions you made during the contribution period.
Leveraging your contributions – Showcase the code, documentation, or tests you submitted. In the May 2026 cohort, selection committees (mentors for each project) will weigh your contributions heavily.
Communicating with mentors – Engage with the mentors of your chosen project. For example, the four selected projects and their mentors are:
- Calling overloaded C++ functions from Rust – Mentored by teor, Taylor Cramer, and Ethan Smith.
- Code coverage of the Rust compiler at scale – Mentored by Jack Huey.
- Fuzzing the a-mir-formality type system implementation – Mentored by Niko Matsakis, Rémy Rakic, and tiif.
- (Fourth project – the original text only listed three; you can add the fourth if known, otherwise mention that additional projects may be added later.)

Step 5: Selection, Acceptance, and Internship

Mentors review applications and contributions to select interns. For the May 2026 cohort, the Rust Project is mentoring four interns due to limited funding and mentoring capacity. If selected:

You'll work full-time (or part-time) for 12 weeks under guided mentorship.
Your stipend is covered by the Rust Project, not by an external sponsor.
You'll collaborate with the community to complete your project and integrate your work into the Rust ecosystem.

If you're not selected, use the experience to strengthen your application for the next outreach cycle or other programs like GSoC.

Tips for a Successful Application

Here are some best practices based on the experiences of past interns and mentors:

Start early. The contribution period is crucial. Begin contributing as soon as projects are announced.
Communicate actively. Ask questions in public channels, attend community meetings, and show that you're responsive to feedback.
Write a clear, focused proposal. Explain what you plan to do, how you'll measure success, and what you've already done. Be realistic about deliverable scope.
Show persistence. Even if your first contribution isn't accepted, keep trying. Mentors value a learner's mindset.
Manage your time. Balance contributions with your other commitments. Outreachy allows part-time work during the internship, but the application phase requires dedicated effort.
Be yourself. Outreachy is about inclusion. Share your story and why you're excited about Rust.

We hope this guide empowers you to apply confidently. The Rust community is welcoming, and Outreachy is a fantastic gateway into open source. Good luck!
