Desirable

• We are hiring a Software Engineer in Test specializing in ML/AI quality, including automation for model evaluation, LLM-assisted test generation, and validation of AI-powered workflows
• The role includes guiding quality strategy and developing automation frameworks
• You will also manage implementation for complex, cross-functional, machine learning-powered products and services
• This role involves more than test development. You will lead quality initiatives from start to finish, ensuring teams stay synchronized, dependencies are managed, and releases are delivered confidently
• You will work closely with ML, engineering, product, and infrastructure teams
• You will shape how quality is built, monitored, and expanded while leading embedded QE efforts within projects
• Define and complete quality strategies, test plans, and automation coverage for ML-powered services and platform components
• Use LLMs and other AI-assisted techniques to generate, expand, and maintain high-value test cases for ML-powered workflows
• Design scenario-based test suites for AI features, including adversarial prompts, edge cases, ambiguous inputs, and underrepresented user scenarios
• Lead QE efforts for multi-functional projects, driving risk assessment, dependency management, and release readiness
• Design, develop, and maintain scalable automation frameworks for backend services, APIs, and ML inference systems using Python and/or Java
• Build automated validation for ML and LLM outputs, including ranking behavior, score distributions, prompt/response quality, hallucination indicators, and probabilistic model evaluation
• Debug test failures, service anomalies, model inconsistencies, and AI behavior regressions to identify root causes and drive resolution
• Perform functional, integration, regression, API, end-to-end, performance, and reliability testing for distributed systems
• Improve automation reliability, reduce flakiness, and optimize execution efficiency
• Partner with engineering and ML teams to integrate automated testing into CI/CD pipelines and release workflows
• Collaborate across teams to establish scalable quality standards, tooling, and guidelines

• Sony Interactive Entertainment conducts background checks at the offer stage for all new employees (which may include criminal background checks for some roles) and will need to process personal information to support these checks
