About the Opportunity

This opportunity is for experienced Senior Software Engineers interested in contributing to advanced AI research and evaluation projects. The role focuses on evaluating AI-generated software solutions, assessing code quality, and helping improve the capabilities of next-generation coding models.

This is not a software development role. Instead, you'll apply your engineering expertise to review AI-generated code, analyze technical decisions, and provide structured feedback that improves AI performance.

Responsibilities

  • Review AI-generated code for correctness, quality, maintainability, and software engineering best practices.
  • Analyze open-source codebases, technical discussions, and software architecture.
  • Evaluate code readability, scalability, reliability, and design decisions.
  • Provide structured technical evaluations with clear engineering reasoning.
  • Collaborate with fellow software engineers to ensure consistent, high-quality evaluations.
  • Apply software engineering expertise to improve the reasoning and capabilities of advanced AI coding models.

Required Qualifications

  • 3+ years of professional software engineering experience (or equivalent open-source experience).
  • Strong expertise in at least one of the following:
  • JavaScript/TypeScript (Node.js, React, modern web development)
  • Go (Golang) (Backend services, distributed systems, REST/gRPC APIs)
  • Python (Backend development, DevOps, automation, testing frameworks)
  • Experience working with large-scale production codebases.
  • Strong understanding of software architecture, debugging, code quality, and engineering best practices.
  • Experience reviewing code for readability, maintainability, and performance.
  • Strong knowledge of Git, GitHub workflows, pull requests, branching strategies, and code reviews.
  • Excellent analytical, problem-solving, and written communication skills.
  • Ability to quickly understand unfamiliar codebases and work independently.

Preferred Qualifications

  • Experience contributing to open-source projects.
  • Familiarity with cloud-native development, Kubernetes, or distributed systems.
  • Experience navigating GitHub repositories and open-source collaboration workflows.
  • Familiarity with SWE-Bench or SWE-Bench Pro.
  • Experience mentoring engineers or conducting technical code reviews.

Compensation

  • Competitive compensation of $50–$75/hour.
  • Weekly payments.
  • Independent contractor engagement.
