OPPO US Research Center is seeking a meticulous and innovative AI/LLM Test Engineer to join our cutting-edge AI team. In this critical role, you will evaluate the performance, reliability, and safety of Large Language Models (LLMs) in real-world product scenarios and test end-to-end generative AI solutions. Your work will directly shape how users experience AI-powered features by ensuring robustness, accuracy, and alignment with product goals. This is a unique opportunity to pioneer testing methodologies for next-generation AI systems at the forefront of technology.
Requirements
Core Testing & Evaluation

  • Design and execute performance tests for LLMs across diverse product use cases (e.g., chatbots, content generation etc.)
  • Develop automated test frameworks to evaluate LLM outputs for accuracy, bias, safety, and coherence
  • Conduct end-to-end testing of integrated generative AI solutions, including APIs, data pipelines, and user interfaces
Optimization & Validation
  • Collaborate with ML engineers to validate fine-tuned models and optimize prompts for target scenarios
  • Analyze model failures, edge cases, and adversarial inputs to identify risks and improvement areas
  • Benchmark LLM performance against industry standards and product-specific KPIs
Collaboration & Quality Assurance
  • Partner with product, engineering, and research teams to define test requirements and acceptance criteria
  • Document defects, performance metrics, and test results to drive data-driven improvements
  • Advocate for AI ethics and safety through rigorous testing of fairness, bias mitigation, and content moderation
Innovation & Tooling
  • Build scalable tools for synthetic test data generation, prompt variation testing, and automated evaluation workflows
  • Stay current with advancements in generative AI testing, including red-teaming techniques and evaluation frameworks (e.g., HELM, Dynabench)
  • Propose novel testing strategies for emerging challenges (e.g., hallucinations, context drift)
Basic Qualifications:
  • Bachelor's degree in Computer Science, Data Science, Engineering, or a related technical field, or equivalent practical experience
  • 1+ years of experience in software testing, data science, or ML validation, with exposure to AI/ML systems
  • Proficiency in Python and testing frameworks (e.g., PyTest, Selenium)
  • Hands-on experience evaluating LLMs in production environments (e.g., GPT, Claude, Llama, Gemini)
  • Strong analytical skills for dissecting model behavior, statistical performance, and failure modes
  • Familiarity with cloud platforms (GCP, Azure, or AWS) and MLOps tooling (e.g., MLflow, Weights & Biases)
  • Experience with version control (Git) and agile development methodologies
Preferred Qualifications:
  • Master's degree in AI, Machine Learning, or a related field
  • Expertise in prompt engineering, LLM fine-tuning (e.g., LoRA, RLHF), or optimization techniques
  • Experience with automated evaluation tools (e.g., LangChain, TruLens) or LLM-specific test suites
  • Knowledge of data pipelines, SQL/NoSQL databases, and API testing (e.g., Postman)
  • Background in statistics, quantitative analysis, or data visualization for test insights
  • Contributions to AI safety/ethics initiatives or open-source LLM evaluation projects
  • Experience testing mobile-integrated AI solutions (Android/iOS)
