A senior software engineer in test at Sony Interactive Entertainment, inside the Information Security team. The work is quality for ML and LLM-powered services: test strategy, automation frameworks in Python or Java, and validation of model outputs — ranking, score distributions, prompt and response quality, hallucination indicators, probabilistic results. The role also covers adversarial and edge-case prompts, CI/CD integration, and leading quality across teams. Requirements include a CS degree or equivalent, five-plus years as an SDET or QE engineer, and hands-on LLM evaluation and prompt-evaluation experience.
