Job Description

Posted on: October 3, 2025

Job Description This is a great opportunity to supplement your income while looking for longer or more full-time work, all while contributing to the development of new AI models using your domain expertise! Our client has hired over 1,000 Braintrust talent and intends to hire hundreds more! Many Braintrust coders earn over $12,000 per month! You’ll have the flexibility to work as much or as little as you choose — 20hrs/week is suggested, but not a limit. Start working in as little as 48 hours. Your final hourly rate will be chosen by Outlier AI and determined by your location. What To Expect If qualified, you’ll be invited to complete a brief questionnaire (3–5 minutes). If you pass, you’ll be approved and able to begin work. Required Qualifications

  • Strong experience with both front-end and back-end development
  • Proficiency in multiple programming languages (front-end and back-end)
  • Ability to describe, evaluate, and critique code in clear English

Preferred Qualifications

  • Bachelor’s and/or Master’s degree in Computer Science (or equivalent work experience)
  • Familiarity with frameworks, libraries, and development environments across front-end and back-end (e.g., modern JavaScript frameworks, backend frameworks, cloud platforms, etc.)

What You’ll Be Working On Our client has partnered with organizations to train AI large language models, helping cutting-edge generative AI models write better code. Example projects might include:

  • Evaluating the quality of AI-generated code across front-end and back-end contexts
  • Solving coding problems in multiple languages, writing functional and efficient solutions
  • Optimizing code for performance and scalability
  • Writing robust test cases to confirm code works effectively
  • Writing human-readable explanations of coding solutions and tradeoffs

💡 No previous experience with AI necessary! You will receive detailed instructions after completing the application and verification process. Note: Outlier AI is partnering with Remotasks for this opportunity.
