What is a software development engineer in testing?

Software Development Engineers in Testing (SDETs) are professionals who specialize in both software development and testing. They design, develop, and maintain automated test frameworks and tools to ensure the quality and functionality of software applications. SDETs work closely with developers to create robust test cases, identify bugs, and improve product reliability. Their role bridges the gap between traditional software testers and developers, requiring strong programming skills as well as a deep understanding of testing methodologies.

What are the key skills and qualifications needed to thrive as a software development engineer in testing?

To thrive as a Software Development Engineer In Testing, you need strong programming skills, a solid understanding of software testing principles, and typically a degree in computer science or a related field. Familiarity with automation tools such as Selenium, JUnit, or TestNG, as well as version control systems like Git, is essential, and certifications in test automation can be advantageous. Analytical thinking, attention to detail, and effective communication are standout soft skills for identifying issues and collaborating with development teams. These skills ensure high-quality, reliable software products through efficient test automation and seamless integration within development workflows.

How does a software development engineer in testing typically collaborate with developers and QA teams during a product release cycle?

SDETs play a key role in bridging the gap between development and quality assurance by working closely with both teams throughout the product release cycle. They participate in code reviews, contribute to designing robust test automation frameworks, and often pair with developers to ensure testability of new features. During sprints, SDETs write, maintain, and execute automated test suites, provide early feedback on potential issues, and help triage bugs. This close collaboration ensures faster feedback loops, higher code quality, and smoother product releases.

Job description

Why Sony Interactive Entertainment?
Sony Interactive Entertainment isn't just the Best Place to Play - it's also the Best Place to Work. Sony Interactive Entertainment (SIE) is the company behind the PlayStation brand. As a subsidiary of Sony Group Corporation, we're part of a proud legacy of innovation and excellence. SIE is a dynamic technology company, delivering cutting-edge hardware and network services to more than 100 million people and an entertainment leader, home to some of the most beloved and recognizable intellectual properties (IP) in the world. Our role at SIE is to create and nurture the experiences under the PlayStation brand, a name synonymous with entertainment excellence and creativity.
At PlayStation, we're passionate about both partnership and technology. We care about building performant products and powerful tools, solving practical problems in delightful ways. We love building the systems that millions of people use, and we're always our own first customers and critics. We strive to be at the forefront of development technologies and celebrate our diversity with engineering teams located on four continents from all walks of life. We build our teams to be places where every voice is heard, all input is valued, and our members have the creative freedom to make their ideas real.
PlayStation is seeking a Software Development Engineer in Test, ML to join our San Mateo team and lead quality efforts for machine learning-powered products and services. You will partner closely with ML engineers, software engineers, product managers, and data partners to build scalable test automation and validation approaches for systems serving PlayStation at global scale. This role is focused on building confidence in model reliability, production readiness, and behavioral consistency. Unlike traditional software backend testing, success here requires validating probabilistic systems through score distributions, cohort-level behavior, thresholds, and statistical signals, not just deterministic pass/fail assertions.
Responsibilities:
  • Design, develop, and maintain automated test frameworks, test scripts for ML inference services and related ML platform components using python/Java
  • Build and automate realistic, representative test account creations and datasets to evaluate model behavior across different scenarios
  • Validate score distributions, ranking behavior, output quality, and other model signals for incoming ML models prior to release
  • Perform different types of testing, including functional, integration, regression and API testing working with RESTful APIs, microservices and databases, and non-functional performance and load testing to verify inference service scalability, latency requirements and reliability under production like conditions
  • Work closely with ML engineers and ops teams to ensure that all features and bug fixes come with automated test coverage, ensuring continuous integration and deployment
  • Debug and analyze test failures, model anomalies and report defects
  • Drive high standards of quality for both engineering decisions and customer-facing features with optimal test and automation strategy
  • Develop and implement best practices for test automation that is highly scalable and maintainable
  • Monitor test execution and optimize performance in test environments
  • Come up with innovative solutions to organizational problems
Required Qualifications:
  • Bachelor's degree or equivalent
  • 3+ years of experience as an SDET, with strong experience testing backend systems.
  • Proficiency in Python/Java/Scala/go for test automation.
  • Hands-on experience with API testing tools (e.g., Postman or similar) for distributed systems
  • Familiarity with CI/CD pipelines and test execution in Jenkins or similar environments such as jenkins, GitHub Actions, ArgoCD, etc
  • Hands-on experience building and maintaining automated test frameworks (e.g., pytest, JUnit, TestNG, etc.)Experience in working with databases for backend validation.
  • Experience with cloud and container technologies (AWS, Google Cloud Platform, Kubernetes, Docker, etc.)
  • Familiarity with monitoring and observability tools (e.g., Prometheus, Grafana, Datadog, etc.) for validating service health
  • Strong understanding of software development lifecycle (SDLC) and agile methodologies.
  • Excellent problem-solving skills and excellent communication skills.
Preferred Qualifications:
  • Experience testing machine learning systems, such as recommendation systems, search ranking systems, or other probabilistic ML application systems.
  • Experience creating synthetic or seeded test data to simulate realistic customer/account behaviors.
  • Experience evaluating model outputs using statistical techniques, distribution analysis, or scenario-based validation, rather than deterministic assertions.
  • Knowledge of data pipelines, feature stores, inference systems or model-serving infrastructure (Seldon, KServe, Ray Serve, etc.) is a plus.
  • Experience testing online services with high RPS and low latency requirements
  • Experience with performance and load testing tools (Locust, k6, Gatling, JMeter, etc.)
  • Experience with Databricks or similar ML platform tooling

Please note that the base pay range may vary in line with our hybrid working policy and individual base pay will be determined based on job-related factors which may include knowledge, skills, experience, and location.
