Overview

In this role you will design and evolve a Python-based testing framework for generative AI agents and LLM-based systems. You’ll shape evaluation pipelines, observability, and data-driven testing, collaborating across AI, data engineering, and QA teams to improve reliability in production. You’ll implement synthetic/adversarial data generation and define quality KPIs to drive trustworthy AI behavior. This is a hands-on, independent role with a strong impact on how we validate AI systems at scale.

Responsibilities
  • Design and develop Python-based testing frameworks for AI agents and LLM systems
  • Contribute to architecture for evaluation pipelines, observability, and data-driven testing
  • Build and maintain test data generation tools (synthetic/adversarial data)
  • Define and implement evaluation strategies and QA KPIs (accuracy, robustness, bias, hallucinations)
  • Integrate LLM evaluation tools, CI/CD, and external AI platforms
  • Support continuous testing, benchmarking, and production monitoring of AI systems
  • Collaborate with AI engineers, data engineers, and QA teams to improve reliability and scalability
Key requirements
  • 2–5+ years of experience in Software Engineering, Test Automation, AI Engineering, or Data Engineering
  • Strong Python proficiency and data/AI libraries (pandas, numpy, PyTorch or similar)
  • Solid understanding of LLMs, NLP concepts, or generative AI systems
  • Experience with test automation frameworks (PyTest, Playwright) and CI/CD
  • Familiarity with data pipelines, dataset design, or feature engineering
  • Experience with evaluation metrics for NLP/AI systems (BLEU, ROUGE, embedding-based metrics)
  • Ability to design scalable systems and work autonomously on complex problems
  • Strong analytical mindset and interest in AI system quality, reliability, and governance
  • autonomous work style
  • collaboration with cross-functional teams
  • analytical mindset
  • Python
  • pandas
  • numpy
