At  Mindrift , innovation meets opportunity. We believe in using the power of collective intelligence to ethically shape the future of AI.

What we do

The Mindrift platform connects specialists with AI projects from major tech innovators. Our mission is to unlock the potential of Generative AI by tapping into real-world expertise from across the globe.

About the Role

GenAI models are improving very quickly, and one of our goals is to make them capable of addressing specialized questions and achieving complex reasoning skills. If you join the platform as an AI Tutor in Coding, you’ll have the opportunity to collaborate on these projects.

Although every project is unique, you might typically :

  • Prompt evaluation and complex data annotation
  • Training and evaluation of large language models
  • Benchmarking and agent-based code execution in sandboxed environments
  • Working across multiple programming languages
  • 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

Note : Flexibility and quick adaptation to new requirements are essential.

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 hold a Bachelor's or Master’s Degree in Computer Science, Software Engineering, Software Development, Computer Engineering, Information Technology or other related fields
  • You have at least 3 years of professional iOS / macOS development experience
  • Your level of English is advanced (C1) or above
  • Mid-level proficiency in Swift 5.9+, including SwiftUI, Combine, async / await, and the concurrency model
  • Hands-on experience with testing frameworks (XCTest, Quick / Nimble) and UI automation testing
  • Proficiency with Xcode, Swift Package Manager, and CI / CD tools (Fastlane, GitHub Actions, Xcode Cloud)
  • Experience with App Store deployment and monitoring tools (Crashlytics, Firebase)
  • Strong understanding of architectural patterns (MVVM, Clean Architecture) and performance optimization (ARC, Instruments)
  • Experience integrating AI / ML capabilities (Core ML, Vision, Create ML)
  • Practical use of AI-assisted tools for code generation, refactoring, and test automation
  • Strong skills in crash analysis, memory debugging, and performance profiling
  • 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.

    • Benefits

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

  • Get paid for your expertise, with rates that can go up to $55 / hour  depending on your skills, experience, and project needs.
  • 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.
