đź“‹ Description

  • • Are you a seasoned mathematician with a passion for Python and a keen eye for detail, seeking flexible, project-based opportunities to leverage your analytical skills? Toloka AI, in partnership with Mindrift, is actively seeking talented individuals to join our network of freelance AI Trainers. This role is designed for experts who can bridge the gap between theoretical mathematical principles and practical AI system evaluation, contributing to the advancement of cutting-edge artificial intelligence technologies for leading tech companies.
  • • As a freelance AI Trainer, you will play a crucial role in the development and refinement of AI systems by engaging in a variety of intellectually stimulating tasks. Your primary responsibility will be to design and implement rigorous mathematical problems that accurately mirror real-world professional scenarios. This involves crafting complex problems that test the limits of AI reasoning and problem-solving capabilities, ensuring they are relevant and challenging.
  • • A significant part of your contribution will involve the meticulous evaluation of AI solutions. You will assess AI outputs for correctness, identify any underlying assumptions or biases, and scrutinize the constraints under which the AI operates. This critical analysis ensures that AI systems are not only accurate but also robust and reliable in diverse applications.
  • • Your Python expertise will be put to excellent use as you validate calculations and simulations. Utilizing powerful libraries such as NumPy, Pandas, and SciPy, you will perform numerical validation, cross-referencing AI-generated results with your own calculations to ensure precision and adherence to mathematical laws. This hands-on validation is essential for building trust in AI system performance.
  • • Beyond validation, you will actively contribute to improving AI reasoning. By analyzing AI responses and identifying logical inconsistencies or deviations from expected outcomes, you will provide feedback and suggest improvements to align the AI's logic with industry-standard practices and human-like reasoning. This iterative process is key to enhancing AI's intelligence and adaptability.
  • • You will apply structured scoring criteria to multi-step problems, providing detailed assessments of AI performance across complex tasks. This requires a deep understanding of the problem domain and the ability to objectively measure the AI's progress and accuracy at each stage.
  • • This opportunity is ideal for individuals who thrive on independent work and are looking for project-based engagements rather than traditional full-time employment. Each project offers a unique set of challenges, allowing you to continuously learn and apply your expertise in new contexts. The flexibility of freelance work means you can manage your workload around other commitments, making it a perfect fit for those seeking supplementary income or a way to stay engaged with challenging technical work.
  • • The projects typically involve tasks estimated to require approximately 10-20 hours per week during active project phases. While this is an estimate and not a guaranteed workload, it provides a clear indication of the time commitment involved when a project is live. Payment is competitive, with rates potentially reaching up to $36 per hour, depending on your expertise, skills assessment, location, and specific project requirements. Some projects may also include performance-based incentive payments, offering further earning potential.
  • • Mindrift connects specialists with project-based AI opportunities for leading tech companies, focused on testing, evaluating, and improving AI systems. Participation is project-based, not permanent employment. This is your chance to work with innovative technologies, contribute to the future of AI, and gain valuable experience with diverse AI applications, all while enjoying the autonomy and flexibility of freelance work. We are looking for individuals who are not only mathematically adept but also possess strong communication skills, particularly in written English, to effectively document their findings and recommendations. Your ability to clearly articulate complex mathematical concepts and evaluation results will be highly valued.
  • • We believe in fair compensation for high-quality work. Rates are determined on a project-by-project basis, considering factors such as the complexity of the tasks, the required expertise, and your demonstrated skills. Higher rates may be offered to highly specialized experts, and lower rates might apply during onboarding or non-core project phases. Detailed payment information will be provided for each specific project, ensuring transparency and clarity in all financial aspects of your engagement.
  • • Join us in shaping the future of artificial intelligence. If you are a mathematician with strong Python skills and a desire to contribute to impactful AI projects, we encourage you to apply and become a valued member of our expert network.
