Job description

This position is listed on behalf of a partner company, which manages all applications and next steps. Our partner is looking for an Analytical Chemistry Specialist – Freelance AI Trainer Project based in Germany.

Are you an analytical chemistry expert interested in contributing to the next generation of artificial intelligence? This freelance opportunity allows you to apply your scientific expertise to train and evaluate advanced AI models designed to support scientific discovery, education, and laboratory research. You will assess AI-generated responses to complex analytical chemistry questions, identify inaccuracies, and strengthen scientific reasoning across a wide range of applications. Your work will help improve the accuracy, reliability, and practical relevance of AI-generated scientific knowledge. Working remotely and independently, you will contribute specialized insights to the development of more capable and trustworthy AI systems. This role is ideal for experienced chemistry professionals who enjoy solving complex problems, communicating scientific concepts, and exploring the intersection of chemistry and emerging technology.

Accountabilities

• Evaluate AI-generated scientific content: Review responses to theoretical and practical analytical chemistry questions, assessing their factual accuracy, logical consistency, scientific rigor, and relevance to real-world laboratory applications.
• Apply specialized analytical chemistry knowledge: Develop and evaluate scenarios involving spectroscopy, chromatography, electrochemical analysis, quantitative chemical analysis, environmental testing, pharmaceutical analysis, and analytical method development.
• Assess advanced analytical techniques: Challenge AI models on mass spectrometry, high-performance liquid chromatography (HPLC), gas chromatography (GC), nuclear magnetic resonance (NMR) interpretation, trace analysis, titrimetric methods, and related instrumentation.
• Identify and document model weaknesses: Record reproducible errors, reasoning gaps, inaccurate interpretations, and other failure patterns to support systematic improvements in model performance.
• Contribute to AI training and evaluation: Provide detailed scientific feedback, propose corrections, and recommend improvements to prompts, evaluation criteria, and testing methodologies.
• Support scientific quality assurance: Apply principles of method validation, quality assurance and quality control (QA/QC), and analytical data interpretation to evaluate the reliability of AI-generated outputs.
• Communicate scientific reasoning clearly: Explain conclusions, demonstrate analytical approaches, and document the steps behind technical judgments to help improve model transparency and reliability.

Requirements

• Education: A PhD in analytical chemistry or a closely related chemical science discipline is preferred. Equivalent advanced expertise supported by relevant professional or research experience may also be valuable.
• Technical expertise: Strong knowledge of analytical chemistry principles, instrumentation, spectroscopy, chromatography, electrochemical methods, quantitative analysis, and analytical method development.
• Research or laboratory experience: Experience in laboratory-based research, analytical method validation, pharmaceutical or environmental testing, instrumentation-intensive studies, or related scientific applications is highly desirable.
• Specialized analytical skills: Familiarity with techniques such as mass spectrometry, HPLC, GC, NMR, trace analysis, titrimetry, and laboratory QA/QC procedures.
• Scientific evaluation skills: Ability to identify factual inaccuracies, assess scientific arguments, interpret experimental scenarios, and distinguish sound conclusions from flawed reasoning.
• Written communication: Excellent technical writing skills and the ability to explain complex scientific concepts clearly, precisely, and logically.
• Analytical thinking: Strong critical-thinking, problem-solving, and attention-to-detail skills, with the ability to break down complex problems and document reproducible findings.
• AI training readiness: Interest in evaluating AI-generated content, identifying model limitations, and contributing to the development of more reliable scientific AI systems.
• Working arrangements: Ability to work independently in a remote freelance environment, manage assignments effectively, and provide a secure computer and reliable high-speed internet connection.

Benefits

• Competitive hourly compensation: A pay range of $8-$65 per hour, with the final rate determined by expertise, professional experience, and geographic location. The final offer may vary from the advertised range.
• Remote flexibility: Work remotely from India, with the flexibility associated with a freelance contract arrangement.
• Meaningful scientific impact: Help shape AI systems that may support scientific education, research, analytical problem-solving, and laboratory workflows.
• Intellectually stimulating work: Apply advanced analytical chemistry knowledge to challenging scientific questions and emerging AI evaluation tasks.
• Specialized professional contribution: Use your research, instrumentation, and laboratory expertise in an innovative technology-focused environment.
• Independent contractor arrangement: Manage your work in a freelance capacity, subject to project requirements and applicable engagement terms.
• Benefits clarification: This is a contract position. Company-sponsored benefits, including health insurance and paid time off (PTO), are not provided. Contractors are responsible for supplying their own computer and high-speed internet connection.
