About the Role

As an SDET II, you'll own significant parts of our test infrastructure and drive quality strategy across the engineering team. You'll design testing approaches for complex features, mentor junior engineers, and make architectural decisions that impact how we approach automation at scale.

What You'll Do

• Architect and implement test frameworks and infrastructure
• Design testing strategies for new features and platform capabilities
• Mentor SDET I engineers and conduct technical code reviews
• Refactor and optimize existing test suites for maintainability and performance
• Make architectural decisions about test design patterns and abstractions
• Build and manage AWS-based test environments and infrastructure
• Integrate testing earlier in the development lifecycle through cross-team collaboration
• Optimize CI/CD pipeline performance and test execution times
• Develop custom tooling and reporting to surface quality insights

Technical Requirements

Core Skills:

• Advanced TypeScript expertise: generics, decorators, advanced typing patterns, type inference
• Deep understanding of asynchronous programming, concurrency, and race condition prevention
• Strong software design principles with domain-driven design (DDD) approach
• Extensive experience with Playwright including deep knowledge of fixtures architecture
• Expert-level Git, GitHub, and distributed version control workflows
• Layered architecture design: understanding PCOM (Page Component Object Model) and POM patterns
• Object-oriented design in test frameworks—building scalable abstractions over linear scripts
• API testing and orchestration (REST/GraphQL integration with UI workflows)

Infrastructure & DevOps:

• AWS: EC2 configuration, CloudWatch log analysis, debugging cloud environments
• Terraform for infrastructure as code (plus)
• Docker: containerization, docker-compose, image management
• CI/CD debugging: analyzing pipeline failures, optimizing execution
• Advanced reporting: Allure configuration, Playwright HTML reports, custom reporting solutions

Additional Experience:

• Test infrastructure development and framework architecture
• Design patterns implementation (Factory, Builder, Facade, Composite)
• Performance optimization at scale
• npm ecosystem and package management
