Dein nächster Schritt. Dein neuer Job.

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Machine Learning (ML) AI Task Auditor - Freelance AI Trainer Project based in Germany.

This freelance opportunity is designed for experienced Machine Learning professionals who want to apply their technical expertise to the development and evaluation of advanced AI systems. You will audit machine learning tasks used to train and evaluate AI models, ensuring they are technically accurate, realistic, reproducible, and practical. The role involves reviewing model development workflows, data preprocessing pipelines, algorithms, and testing approaches against rigorous technical standards. You will identify data pipeline flaws, model training inefficiencies, algorithmic logic errors, and other issues that could affect task quality. Your feedback will help improve the reliability and technical integrity of AI training and evaluation workflows.

The project offers a flexible, remote environment where specialized machine learning expertise can directly influence the quality of AI systems. As a freelance contributor, you will work independently on challenging technical assignments while helping ensure AI evaluation tasks reflect real-world machine learning practices.

Accountabilities

• Evaluate machine learning tasks to determine whether they are technically accurate, realistic, solvable, reproducible, and supported by reliable tests and evaluation criteria.

• Review model development workflows, data preprocessing pipelines, and machine learning implementations for technical correctness and practical relevance.

• Assess whether algorithms, training approaches, and expected outcomes are logically sound and appropriately defined.

• Identify data pipeline flaws, model training inefficiencies, algorithmic logic errors, and other technical issues that may compromise task quality.

• Rigorously test and troubleshoot complex machine learning scenarios to validate task behavior and expected results.

• Provide clear, actionable technical feedback on identified issues and recommend improvements where appropriate.

• Apply specialized machine learning knowledge to ensure AI training and evaluation tasks meet high standards of accuracy, rigor, and reproducibility.

• Document technical findings clearly and consistently across assigned project tasks.

Requirements

• Demonstrable professional experience and deep technical knowledge in Machine Learning, including model development and data preprocessing pipelines.

• Strong hands-on experience with machine learning frameworks such as PyTorch or TensorFlow.

• Strong understanding of machine learning algorithms, model training workflows, data preparation, and technical evaluation practices.

• Strong analytical and problem-solving skills, with the ability to rigorously test, troubleshoot, and evaluate complex technical scenarios.

• Excellent attention to detail and the ability to identify subtle data, model, algorithmic, testing, and reproducibility issues.

• Ability to objectively assess technical tasks against requirements for accuracy, realism, solvability, and reliable evaluation.

• Strong written communication skills for providing precise, constructive, and actionable technical feedback.

• Ability to work independently and apply specialized expertise within a freelance, project-based environment.

• Candidates will be considered for one area of specialization based on their professional experience; expertise across other domains is not required.

• Ability to provide a secure computer and reliable high-speed internet connection for freelance project work.

Benefits

• Compensation of $70–$100 per hour, with the exact rate determined based on experience, expertise, and geographic location.

• Final compensation may vary from the published range following evaluation of your qualifications and location.

• Freelance contract structure offering flexibility for project-based work.

• Remote work environment.

• Opportunity to contribute directly to the training and evaluation of advanced AI systems.

• Opportunity to apply specialized Machine Learning expertise to technically challenging AI evaluation projects.

• Health insurance, paid time off, and other company-sponsored employee benefits are not provided under the freelance contract.

• Contractors are responsible for supplying their own secure computer and high-speed internet connection.
