Evaluate and stress-test user interfaces built by AI models to identify frontend failures in components, state management, accessibility, and rendering. Write correct implementations when models fall short, providing the training signal through clear technical explanations of what works and what breaks.
A Full Stack Engineer working with frontier AI models to evaluate their ability to build complete applications across frontend, API, and database layers. You will trace features through the entire stack to identify where models fail, write corrected versions when needed, and provide detailed explanations that serve as training data for improving future model outputs.
Review and evaluate AI model responses across everyday topics for accuracy, helpfulness, and tone. This role requires careful analysis and clear writing to assess output quality and provide ratings based on defined rubrics.
This role involves evaluating and correcting German language output from AI models to improve naturalness and accuracy. You will assess translations, rate model outputs, and rewrite text to sound native while teaching AI systems how German is actually spoken, including regional variations and proper formality levels.
Evaluate AI models on Gujarati translation and localization tasks, assessing the quality of machine-generated outputs and providing corrections. The role involves analyzing errors in AI-generated Gujarati text, explaining failure modes, and writing better translations to help train improved language models.
DataAnnotation seeks an experienced hardware engineer to evaluate how AI models handle real electrical and electronics engineering problems. You will design realistic engineering challenges, run them through frontier AI models, judge the outputs against professional standards, and provide detailed written critiques that help train the next generation of AI engineering tools.
This role involves evaluating AI-generated responses to health and medical questions for clinical accuracy and safety. The expert identifies errors in reasoning, missed contraindications, unsafe advice, and writes correct answers grounded in current clinical practice, ensuring AI models provide guidance that real clinicians would trust.
You will evaluate AI model responses to healthcare compliance questions, identifying gaps in HIPAA knowledge and regulatory understanding. Your role is to assess whether AI correctly handles privacy disclosures, retention rules, and healthcare regulatory risks, then provide accurate compliance guidance when the model falls short.
This role involves evaluating AI-generated responses about healthcare administration and operations, including billing, coding, insurance workflows, and compliance. You will write test prompts, review AI outputs for accuracy and feasibility, and provide correct guidance based on practical operational experience.
This role involves evaluating and correcting AI-generated Hebrew text, focusing on grammatical accuracy, gender agreement, and appropriate register. You will review translations, rate model outputs, and write improved versions to train AI systems to handle Hebrew's linguistic complexities.
This role involves evaluating and correcting AI-generated Hindi text translations, assessing them for accuracy, fluency, and cultural appropriateness. As a Hindi specialist, you will rate model outputs and write improved versions that sound natural to native speakers, helping train AI models to produce authentic Hindi language content.
This role involves judging how frontier AI models handle Icelandic translation, localization, and cultural nuance on real projects. The reviewer rates model outputs, pinpoints errors, and explains why they happen. It suits people with professional language expertise who can write clear English explanations.
This role involves evaluating how AI models handle incident response tasks including detection, triage, and forensics. You will identify flaws in the model's reasoning, catch critical mistakes that would compromise real security incidents, and write correct analysis based on actual incident response practices.
This role involves evaluating and correcting AI-generated Indonesian text for accuracy, fluency, and cultural appropriateness. As an Indonesian specialist, you will assess translations and model outputs, rewriting them when necessary to match how native speakers actually communicate.
This role involves evaluating AI systems that price insurance risks and make claims decisions by reviewing underwriting logic, policy language interpretation, and risk assessment. Insurance professionals will verify whether AI models correctly apply underwriting principles, pricing models, and policy terms, then provide written feedback to improve model training.
Review and evaluate AI-generated investment banking deal analysis, including valuation models, transaction mechanics, and M&A structures. Provide expert feedback and corrections to train AI models on real banking standards and practices.
As an IP Attorney, you will evaluate how AI models handle patent prosecution, trademark analysis, and IP strategy work. You'll test the model's reasoning on patentability, claim construction, and prior art analysis, then write rigorous legal opinions to correct errors and train the system. This role suits experienced IP practitioners who can identify and remedy flawed AI reasoning across intellectual property domains.
This role involves evaluating and correcting AI-generated Italian text to ensure it captures native fluency, proper formality levels, and regional authenticity. You will rate model outputs, identify linguistic issues like incorrect gender agreement and unnatural phrasing, and rewrite examples to match how Italians actually speak.
This role involves evaluating and correcting AI-generated Japanese text to improve its linguistic accuracy and cultural appropriateness. As a Japanese specialist, you will assess translations, identify issues with politeness levels (keigo), grammar, and natural flow, then provide corrected versions that sound native to Japanese speakers.
Evaluate AI model outputs on Kannada translation and localization tasks, identifying errors and providing high-quality corrections. The role involves reviewing real-world language work, analyzing model failures, and contributing to AI training data through detailed linguistic assessment.
