• Build and maintain evaluation datasets for AI models across programming languages (Python, Golang, JavaScript, Java).

• Develop and apply data labeling and scoring guidelines based on Google’s evaluation framework.

• Implement LLM-judge calibration workflows to align automated and human evaluations.

• Perform error analysis, drift detection, and regression testing of AI model outputs.

• Collaborate with automation engineers to integrate datasets into evaluation pipelines.

• Support rater training, inter-rater reliability checks, and dataset validation reviews.

• Manage data quality assurance and documentation for contributions to Google-maintained repositories.

Required Skills & Experience

• 4–8 years of experience in AI/ML data operations, evaluation, or data engineering.

• Proficiency in Python (mandatory) for dataset manipulation, analysis, and scripting.

• Experience with LLM evaluation, prompt engineering, or text generation quality assessment.

• Familiarity with Gemini CLI, Vertex AI, or LangChain evaluation tools.

• Strong understanding of data curation, annotation workflows, and labeling quality metrics.

• Hands-on with Git-based repositories and CI/CD data workflows.

• Excellent analytical and problem-solving skills with attention to detail.

Preferred Qualifications

• Experience evaluating code-generation or NLP-based AI products.

• Exposure to data governance and privacy compliance frameworks.

• Background in computer science, data science, or linguistics preferred
