Job description

This job is with our partner Micro1.

Job Summary

In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required — your domain knowledge is what matters.

You'll create realistic, interesting and challenging coding tasks for AI to solve involving feature implementation and bug fixes, and implement deterministic verifiers that accept reasonable valid solutions and reject everything else.

What we're looking for

• Strong backend experience in Java, Node.js, Go, Rust, Typescript, Python, C++ or similar

• A track record building scalable services and APIs

• Comfort with debugging, performance work and automated testing

• Solid code review instincts

• A strong testing background is a big plus — experience designing test strategy, building and maintaining large test suites, diagnosing flaky tests, or raising the testing bar on a team.

Preferred Qualifications

• Proven experience in backend development, with a track record of delivering high-quality and performant projects.

• Demonstrated success in identifying and resolving software bugs and system bottlenecks.

• Experience with codebase refactoring and implementing complex features in large-scale applications.

• Strong understanding of algorithms, data structures, and foundational computer science concepts.

• Excellent analytical, problem-solving, and technical communication skills.

Process:

1. Complete AI Interview (approx. 30 minutes)

2. Technical Assessment (Tentative)

3. Hiring Manager review
