## About the Role

* Professional software engineering experience shipping real, scaled production systems
 * Expertise in at least one common tech stack (TypeScript, Python, Ruby, PHP, Java, Rust, Go, or C++)
 * Strong judgment about what "good code" and a "meaningful model failure" look like
 * Comfort working independently, and giving direct, code-review-style feedback
 * Availability for a meaningful commitment (most contributors work 20 to 40+ hours per week)

Note: You do not need prior AI or ML experience. Strong engineering judgment and attention to detail matter most.
What makes this different

 * Background check
 * Paid first real task. Do well, and you're on the team.
