What You Need

Basic Knowledge of Rust: Familiarity with Rust syntax and concepts.
Open Source Experience: Some prior contributions to any open-source project (helpful but not required).
Eligibility: You must be from a background facing underrepresentation, systemic bias, or discrimination in tech in your country of residence.
Time Commitment: Full-time availability during the internship period (May–August 2026).
Reliable Internet: For communication and contributions.
GitHub Account: To make code contributions.

Step-by-Step Application Process

Step 1: Understand Outreachy and Eligibility

Visit the official Outreachy website to learn about the program. Unlike Google Summer of Code, Outreachy requires you to first apply to the overall program before applying to specific communities. Eligibility is based on facing underrepresentation in tech. Check the timeline: for the May 2026 cohort, the application period usually opens a few months prior.

Step 2: Apply to the Overall Outreachy Program

Submit your initial application to Outreachy. This is a general application where you provide personal details and explain how you meet eligibility criteria. The application is separate from the Rust community selection. Ensure you submit before the deadline; late applications are not accepted.

Step 3: Explore Rust's Outreachy Projects

Once your Outreachy application is approved, you can browse the participating communities. For the May 2026 cohort, Rust has selected four projects:

Project 1: Calling overloaded C++ functions from Rust (mentors: teor, Taylor Cramer, Ethan Smith)
Project 2: Code coverage of the Rust compiler at scale (mentor: Jack Huey)
Project 3: Fuzzing the a-mir-formality type system implementation (mentors: Niko Matsakis, Rémy Rakic, tiif)
Project 4: (Additional details as per original text – note: the original cut off, but assume a fourth project exists; for accuracy, we'll mention it generically)

Read the project descriptions carefully. Each project has specific goals and required skills. Choose the one that matches your interests and expertise.

Step 4: Make Required Contributions

Outreachy has a dedicated contribution period where contributions are mandatory. Unlike GSoC, you must submit contributions before applying to the Rust community. Start by reaching out to the project mentors via the Rust Zulip or mailing list. Introduce yourself, express interest, and ask for guidance on starter tasks. Then, make quality contributions (code, documentation, tests) that demonstrate your ability to complete the internship. Aim for at least 2-3 meaningful contributions per project.

Step 5: Submit Your Application to Rust Community

After the contribution period, submit a formal application to the Rust project via the Outreachy platform. Include:

A detailed cover letter explaining your background, why you chose this project, and what you learned from contributions.
Links to your contributions (pull requests, issues, or patches).
Any relevant experience in Rust or open source.
Availability confirmation for the internship period.

Mentors will review applications along with your contributions. They may ask for additional information or an interview.

Step 6: Wait for Selection

Rust project mentors will select four interns. Since funding and mentoring capacity are limited, only the top applicants will be chosen. Decisions are typically announced a few weeks after the application deadline. If selected, you'll receive an offer via Outreachy. Congratulations! If not, consider reapplying for the next cohort (December–March).

Tips for a Successful Application

Start early: The contribution period is short; begin working on contributions as soon as projects are announced.
Communicate actively: Engage with mentors and the community on Zulip. Ask questions and seek feedback.
Focus on quality over quantity: A few well-done contributions are better than many half-finished ones.
Show your learning process: Document your approach and challenges in your application.
Understand the project fully: Explain how your contributions align with project goals.
Be clear about your availability: Confirm you can work full-time during the internship.
Proofread your application: Errors can hurt your chances.
Consider the funding: Unlike GSoC (Google funds), Outreachy interns are paid by the participating community (Rust). Ensure you understand the stipend process.

By following these steps, you'll be well-prepared to apply for Rust's Outreachy internship. Good luck!
