ML Evaluation Engineer

Summary

We are looking for an ML Evaluation Engineer/Data Scientist to bring statistical rigor and measurement excellence to the evaluation of AI and LLM systems. This role will focus on ensuring that evaluation results are reliable, reproducible, and scientifically valid. 

The successful candidate will partner closely with ML Evaluation Engineers and Applied Scientists to answer critical questions such as: Is this performance improvement real, Are our evaluators aligned, and Can we trust these results 

Key Responsibilities:

• Design and execute statistical analyses for AI and LLM evaluation programs. 
• Measure and improve inter-annotator agreement between human evaluators. 
• Develop sampling methodologies and evaluation datasets to ensure representative results. 
• Perform significance testing and statistical validation of model performance changes. 
• Analyze golden sets and benchmark datasets to assess model quality and consistency. 
• Build dashboards and reporting frameworks to monitor evaluation outcomes and trends. 
• Identify sources of evaluation noise, bias, and inconsistency. 
• Partner with ML Evaluation Engineers to validate automated judges against human raters. 
• Provide data-driven recommendations regarding evaluation quality and model readiness. 

Must Have Skills:

• Bachelor's degree in Statistics, Data Science, Computer Science, Mathematics, Machine Learning, or a related field. 
• Minimum 2+ years of professional experience in Data Science, Evaluation Science, Applied Statistics, or related disciplines. 
• Strong foundation in statistical analysis, hypothesis testing, experimental design, and measurement methodologies. 
• Experience working with structured and unstructured data using Python, SQL, and data analysis tools. 
• Ability to communicate statistical findings clearly to technical and non-technical stakeholders. 
• Experience building analytical dashboards and reporting solutions. 

Nice to haves:

• Master's degree or PhD in Statistics, Data Science, Computer Science, Quantitative Social Sciences, or a related discipline. 
• Direct experience supporting LLM, AI, NLP, or ML evaluation initiatives. 
• Experience measuring agreement between human raters and automated evaluation systems. 
• Knowledge of annotation quality frameworks, golden-set construction, sampling theory, and evaluation benchmarking. 
• Familiarity with LLM-as-Judge frameworks and AI evaluation platforms. 

We regret to inform that only shortlisted candidates will be notified / contacted.
