How to Become a Rust Project Outreachy Intern for the May 2026 Cohort

Outreachy provides paid internships in open source to people from underrepresented backgrounds. The Rust Project is proud to participate in the May 2026 cohort, offering four mentored positions. This guide walks you through the entire process, from understanding eligibility to submitting a strong application. Unlike Google Summer of Code (GSoC), Outreachy requires a dedicated contribution period before you apply to a specific community. Follow these steps to maximize your chances of joining the Rust team.

What You Need

Eligibility: You must belong to a group facing underrepresentation, systemic bias, or discrimination in tech in your country. Check Outreachy's website for details.
Time commitment: Full-time internship (40 hours/week) from May to August 2026.
Basic Rust knowledge: Familiarity with Rust syntax, ownership, and traits is helpful. Some projects may require C++ or type theory experience.
Open-source contribution skills: Ability to communicate asynchronously, use Git, and submit pull requests.
Computer and internet: Reliable access for development and meetings.

Step-by-Step Guide

Step 1: Understand Outreachy vs. GSoC

Outreachy differs from GSoC in three key ways. First, you apply to the overall Outreachy program before applying to specific communities like Rust. Second, Outreachy has a mandatory contribution period where you must submit patches or other work to the community before your application. Third, the intern stipend is covered by the participating community (the Rust Project) rather than by a central sponsor. This means Rust has limited funding—only four interns for the 2026 cohort.

Step 2: Review the Rust Project's Selected Projects

Familiarize yourself with the four projects and their mentors. Each has different focus areas:

Calling overloaded C++ functions from Rust – Mentored by teor, Taylor Cramer, and Ethan Smith. Involves implementing experimental FFI features.
Code coverage of the Rust compiler at scale – Mentored by Jack Huey. Develop workflows to analyze test coverage across the compiler and ecosystem.
Fuzzing the a-mir-formality type system implementation – Mentored by Niko Matsakis, Rémy Rakic, and tiif. Build tools to fuzz an in-progress type system model.
Fourth project details were not fully provided in the original announcement; check the Rust blog for updates.

Select a project that matches your interests and skills. Contact mentors early via Zulip or GitHub to introduce yourself.

Step 3: Complete the Outreachy Contribution Period

Outreachy requires contributions before you can apply to a community. During the contribution period (typically several weeks before the application deadline), you must:

Choose one or two Rust projects from the above list.
Submit at least one substantial contribution (code, documentation, bug fixes, or tests).
Engage with mentors and the community on the project's issue tracker or chat.
Write a small blog post or journal entry describing your contributions (optional but recommended).

This is the most critical step: your contributions demonstrate your ability to collaborate and produce quality work.

Step 4: Apply to the Outreachy Overall Program

Go to the Outreachy website (outreachy.org) and submit your initial application. You'll provide:

Personal information and eligibility proof.
A statement of interest in open source.
Reference contacts.

The overall program application is separate from the community application. Wait for confirmation that you are accepted as an Outreachy applicant before proceeding.

Step 5: Apply to the Rust Community

Once you are an approved Outreachy applicant, you can apply to the Rust Project. Prepare a document that includes:

A description of your contributions during the contribution period.
Your motivation for wanting to work on your chosen project.
Relevant experience (Rust, C++, fuzzing, compilers, etc.).
Availability for a full-time internship (May–August 2026).

Submit via the Outreachy application portal before the deadline. Mentors will review contributions and applications together.

Step 6: Prepare for Selection and Onboarding

If selected, you will be notified by Outreachy and the Rust team. Congratulations! Prepare by:

Setting up your development environment for the specific project.
Reading relevant Rust RFCs or design documents.
Scheduling weekly meetings with your mentor(s).
Understanding the stipend payment process (Rust Project covers your stipend).

Tips for Success

Start early: The contribution period may begin a month before the application deadline. Begin exploring projects and codebase as soon as the cohort is announced.
Communicate openly: Ask mentors for clarification on tasks. Regular check-ins show initiative.
Show iterative progress: Instead of one giant contribution, submit smaller patches and respond to feedback. This builds trust.
Be resilient: Outreachy is competitive. Even if not selected for Rust, you may be considered by other communities—apply broadly.
Learn from the code: Use this opportunity to deepen your Rust skills. The projects touch on advanced topics like FFI, type systems, and compiler internals.
Network: Join the Rust community Zulip and contribute to discussions beyond your project. Mentors appreciate enthusiastic team players.
