Toronto, Ontario, Canada Mercor Full time $800,000 - $1,000,000 per year

Mercor is partnering with a top AI research organization to evaluate and improve how coding assistants reason, act, and communicate during development workflows. We're seeking technically sharp experts (especially those with experience in code review, testing, or documentation) to assess full transcripts of user–AI coding conversations. This short-term, fully remote engagement helps shape the future of developer-assisting AI systems.

Key Responsibilities


• Review long-form transcripts between users and AI coding assistants


• Analyze the AI's logic, execution, and stated actions in detail


• Score each transcript using a 10-point rubric across multiple criteria


• Optionally write brief justifications citing examples from the dialogue


• Detect mismatches between claims and actions (e.g., saying "I'll run tests" but not doing so)

Ideal Qualifications

Top choices:


• Senior or Staff Engineers with deep code review experience and execution insight


• QA Engineers with strong verification and consistency-checking habits


• Technical Writers or Documentation Specialists skilled at comparing instructions vs. implementation

Also a strong fit:


• Backend or Full-Stack Developers comfortable with function calls, APIs, and test workflows


• DevOps or SRE professionals familiar with tool orchestration and system behavior analysis

Languages and Tools:


• Proficiency in Python is helpful (most transcripts are Python-based)


• Familiarity with other languages like JavaScript, TypeScript, Java, C++, Go, Ruby, Rust, or Bash is a plus


• Comfort with Git workflows, testing frameworks, and debugging tools is valuable

More About the Opportunity


• Remote and asynchronous — complete tasks on your own schedule


• Must complete each transcript batch within 5 hours of starting (unlimited tasks to be done)


• Flexible, task-based engagement with potential for recurring batches

Compensation & Contract Terms


• Competitive hourly rates based on geography and experience


• Contractors will be classified as independent service providers


• Payments issued weekly via Stripe Connect

Application Process


• Submit your resume to begin


• If selected, you'll receive rubric documentation and access to the evaluation platform


• Most applicants hear back within a few business days
