• Prompt evaluation and complex data annotation
• Training and evaluation of large language models
• Benchmarking and agent-based code execution in sandboxed environments
• Adapting guidelines for new domains and use cases
• Following project-specific rubrics and requirements
• Collaborating with project leads, solution engineers, and supply managers on complex or experimental projects

How to get started

Simply apply to this post, qualify, and get the chance to contribute to projects aligned with your skills, on your own schedule. From creating training prompts to refining model responses, you’ll help shape the future of AI while ensuring technology benefits everyone.

Requirements

• You have a Bachelor's in Software Development, Computer Science, or other related fields.
• You have at least 3 years of professional experience with testing frameworks/automation tools (Playwright, Cypress, Jest) in TypeScript environments.
• Experience with code review, quality analysis, and identifying/fixing code smells and type issues.
• Familiar with test integration in CI/CD environments.
• Experience using, integrating, or tutoring others in AI/ML or LLM-powered testing/coding solutions.
• Strong documentation and bug-tracking skills.
• Hackathon or competitive coding experience is a plus.
• Your level of English is advanced (C1) or above.
• You are ready to learn new methods, able to switch between tasks and topics quickly and sometimes work with challenging, complex guidelines.
• Our freelance role is fully remote so, you just need a laptop, internet connection, time available and enthusiasm to take on a challenge.

Why this freelance opportunity might be a great fit for you?

• Take part in a part-time, remote, freelance project that fits around your primary professional or academic commitments.
• Work on advanced AI projects and gain valuable experience that enhances your portfolio.
• Influence how future AI models understand and communicate in your field of expertise.
