AI Evaluation Engineer

This role is for one of the Weekday's clients

We are seeking an AI Evaluation Engineer to evaluate, validate, and ensure the quality of AI/ML systems working with complex, real-world data. This role focuses on assessing component mapping, retrieval-augmented generation (RAG) based Q&A systems, and feature extraction from structured and unstructured sources such as repair records, catalogs, free-text inputs, and technical documentation.

This is a hands-on engineering role centered on designing custom evaluation frameworks, datasets, and automated pipelines (including LLM-as-a-judge approaches) to measure quality, detect regressions, and support release readiness. While domain training will be provided, strong ownership in building evaluation intuition and maintaining high-quality test datasets is essential.

Key Responsibilities

AI Evaluation & Quality Assurance

• Evaluate ML and LLM outputs using defined metrics, benchmarks, and acceptance criteria.
• Design and maintain automated evaluation pipelines to assess model accuracy, consistency, and reliability.
• Develop and own high-quality evaluation datasets, golden test cases, and benchmarks.

Testing & Release Validation

• Execute evaluation-driven smoke tests and regression tests prior to releases.
• Track quality metrics and provide clear go/no-go signals for production deployments.
• Detect regressions and unexpected model behavior across releases and data changes.

Analysis & Insights

• Analyze evaluation results to identify trends, inconsistencies, and failure patterns.
• Provide actionable insights to improve model performance and system behavior.

System & API Validation

• Validate AI services at the API level for correctness, robustness, and stability.
• Monitor system performance, latency, and error rates under production-like workloads.

Cross-Functional Collaboration

• Work closely with ML, backend, and product teams to define expected AI behavior.
• Ensure evaluation coverage aligns with real-world use cases and business requirements.

Skills & Experience

Core Skills

• Strong proficiency in Python for evaluation scripting and automation.
• Solid understanding of Machine Learning and AI systems, including LLM-based workflows.
• Experience with data analysis to interpret evaluation metrics and model outputs.

Nice to Have

• Experience with LLM evaluation frameworks or LLM-as-a-judge techniques.
• Familiarity with RAG pipelines, NLP systems, or large-scale data processing.
• Experience building CI/CD-style evaluation or testing pipelines for AI systems.
