Your Guide to Participating in Rust's Outreachy Program

Overview

The Rust Project has steadily built a tradition of embracing open-source mentorship programs, including multiple years with Google Summer of Code and OSPP. We are thrilled to extend this commitment by participating in Outreachy starting with the May 2026 cohort. Outreachy is a global program that provides paid internships in open source to people from underrepresented backgrounds in technology. Unlike other programs, Outreachy places strong emphasis on required contributions during a dedicated period and has a two-step application process. For the May 2026 cohort, the Rust Project is mentoring four interns, each working on impactful projects ranging from C++ interop to compiler fuzzing.

Prerequisites

Before diving into the application process, ensure you meet these criteria:

Eligibility for Outreachy: The program is open to people from any background who face underrepresentation, systemic bias, or discrimination in the technical industry in their country of residence. Check the official Outreachy website for detailed eligibility rules.
Rust familiarity: Basic understanding of Rust syntax, tooling, and ecosystem. Strong candidates have at least a few small projects or contributions.
Open-source experience (recommended): Prior contributions to any open-source project (not necessarily Rust) help demonstrate collaboration skills.
Time commitment: Interns are expected to work full-time (40 hours/week) during the internship period (May–August or December–March) or at a reduced schedule approved by mentors.
Communication skills: Ability to discuss technical topics in English on public forums like Zulip, GitHub, or mailing lists.

Step-by-Step Application Guide

Step 1: Apply to the Outreachy Program

Outreachy requires a two-stage application. First, submit an initial application to the Outreachy program itself through their official application system. This application gathers demographic information, your statement of interest, and confirms your eligibility. The deadline is typically a month before the contribution period begins.

Step 2: Choose Rust as Your Community

During the Outreachy contribution period, registered applicants browse participating communities. Select the Rust Project from the list. At this stage, no commitment is required yet.

Step 3: Make Required Contributions

This is the most critical step. Unlike Google Summer of Code, Outreachy mandates a period where applicants must make contributions to the community’s project. For Rust, contributions may include:

Code patches: Fixing bugs, implementing small features, or improving documentation.
Testing: Writing tests or running coverage tools.
Fuzzing: Setting up fuzzing harnesses for Rust’s type system models.
Communication: Asking questions on the project’s Zulip and showing your work in progress.

These contributions help mentors evaluate your skills, initiative, and fit for the project. Aim for at least three to five substantial contributions.

Step 4: Submit Your Application to the Rust Project

After making contributions, submit a formal application through Outreachy’s system. This includes a statement of interest, your contribution history, and any special circumstances. The Rust mentorship team reviews applications alongside your contributions and selects interns.

The Rust Project will mentor four interns for the May 2026 cohort. Below are the selected projects and mentors:

Calling overloaded C++ functions from Rust – Mentors: teor, Taylor Cramer, Ethan Smith. Intern: Ajay Singh. This experimental feature aims to simplify Rust–C++ interop by automatically resolving overloaded C++ functions.
Code coverage of the Rust compiler at scale – Mentor: Jack Huey. Intern: Akintewe Oluwasola. Building workflows to run and analyze compiler test suite coverage and ecosystem crates to detect under-tested areas.
Fuzzing the a-mir-formality type system implementation – Mentors: Niko Matsakis, Rémy Rakic, tiif. Intern: Tunde-Ajayi Olamiposi. Implementing fuzzing for an in-progress model of Rust’s type and trait system.
(Fourth project not detailed in original text; likely will be announced soon.)

Step 5: Acceptance and Onboarding

If selected, you’ll receive a contract from Outreachy. The Rust Project covers intern stipends and overhead, funded by the community. Upon acceptance, you’ll get invited to the Rust Zulip, meet your mentors, and begin a structured onboarding.

Common Mistakes

Skipping the initial Outreachy application: Many applicants focus on community contributions but forget to complete the program-level application first. Without it, your contributions won’t be considered.
Waiting too long to start contributions: The contribution period is limited. Start as soon as the period opens to build a strong record.
Not engaging with the community: Your contributions must be visible and discussed in public channels. Silence suggests lack of communication skills.
Misunderstanding eligibility: Outreachy is only for underrepresented groups. Check your country’s discrimination laws and the program’s definitions before applying.
Overcommitting to multiple projects: Focus on one or two projects within Rust to produce quality contributions, not quantity.
Assuming similarity to GSoC: Outreachy has a different application flow and funding model. Do not reuse a GSoC application without adaptation.

Summary

Rust’s participation in Outreachy opens a unique pathway for talented individuals from underrepresented backgrounds to contribute to key compiler, tooling, and language design projects. By following the two-step application, making the required contributions, and avoiding common pitfalls, you can position yourself as a strong candidate. The program offers a stipend, mentorship from top Rust core team members, and the chance to impact the future of Rust. Mark your calendar for the May 2026 cohort and start preparing today.
