About The Role

We're pioneering a new role focused exclusively on quality assurance for GenAI/Agentic systems. As our Senior SDET for AI, you'll develop testing strategies, evaluation frameworks, and quality metrics specifically designed for LLM-powered applications. This role requires a unique blend of QA expertise, understanding of GenAI behaviour, and automation skills to ensure our AI features are reliable, accurate, and trustworthy.

Your Impact

• Design and architect comprehensive test plans, evaluation frameworks, and quality metrics designed specifically for LLM-powered applications and agentic workflows.
• Develop robust, end-to-end automated test suites in Python across evaluations, API checks, UI checks, and performance tests.
• Create automated prompt testing systems and regression suites to proactively detect unintended changes in model behaviour.
• Establish multi-dimensional evaluation criteria to measure and track GenAI quality across accuracy, relevance, safety, consistency, and latency.
• Perform adversarial testing (red‑teaming) to identify and mitigate model hallucinations, biases, or security vulnerabilities.
• Develop internal tools and testing frameworks that enable software engineering teams to seamlessly validate their own GenAI implementations.
• Deploy real‑time monitoring and alerting systems to quickly detect and flag quality degradation of AI features in production.
• Own the overall quality and testing strategy for your workstream, maintaining high‑fidelity test datasets ("golden examples") and defining QA best practices.

Your Skills

• Deep understanding of GenAI technologies including LLMs, prompt engineering, and AI application patterns.
• Strong hands‑on Python coding experience.
• Expert experience with test automation frameworks and scripting (Python, JavaScript, Selenium, Pytest).
• Strong background of software testing methodologies (functional, integration, regression, performance, security testing).
• Proven ability to design test cases and evaluation criteria for non‑deterministic systems.
• Strong analytical and problem‑solving skills with attention to detail.
• Experience with API testing tools (Postman, REST Assured) and backend testing.
• Strong experience with CI/CD pipelines and automated testing integration.
