Llm QA

Key Responsibilities
Test Planning & Execution
Validate data pipelines, model outputs, APIs, and user interfaces with a focus on LLM-driven features such as text generation, summarization, and classification.
LLM Quality & Evaluation
Develop test cases for LLM responses, ensuring accuracy, relevance, consistency, and compliance.
Evaluate prompt quality, model outputs, and fine-tuned model behavior using both manual and automated techniques.
Support RAG pipelines and validate integration with vector databases or knowledge sources.
Automation & Tooling
Build and maintain automated test suites for backend services and LLM workflows using tools like PyTest, Postman, Selenium, or Playwright.
Integrate tests into CI/CD pipelines (e.g., using GitHub Actions, Jenkins, or CodePipeline).
AWS Integration Testing
Test cloud-native services and workflows built with AWS tools such as:
Lambda, S3, API Gateway, Step Functions, Bedrock, SageMaker, CloudWatch
Validate infrastructure-as-code using CloudFormation or CDK in test environments.
Performance, Security & Compliance Testing
Conduct performance testing of LLM APIs (e.g., latency, throughput, model fallback behavior).
Ensure compliance with data privacy, audit, and security standards when using LLMs in production workflows.
Collaboration & Documentation
Work closely with engineers, data scientists, and product managers to define quality metrics for LLM use cases.
Document test strategies, bug reports, and QA process improvements.
Technical Skills
5+ years of experience in software or data quality assurance.
Experience testing or validating LLM-powered features (e.g., OpenAI, Amazon Bedrock, HuggingFace, Claude).
Strong skills in test automation (e.g., PyTest, Selenium, REST API testing).
Good understanding of CI/CD and DevOps in AWS environments.
Experience with Python or JavaScript/TypeScript for test scripting.
Nice to Have
Familiarity with LLMOps, prompt testing frameworks, or prompt injection scenarios.
Experience with LangChain, RAG patterns, or vector databases (e.g., Pinecone, FAISS).
Exposure to model evaluation metrics (e.g., BLEU, ROUGE, factual consistency).
Basic knowledge of data pipelines, ETL, or analytics workflows.
Preferred Experience
Ensuring ethical AI usage, data privacy, and compliance in AI workflows.
Familiarity with monitoring LLM behaviour in production and logging tools.
