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 shape how we approach automation at scale.

WHAT YOU'LL DO

- Build test infrastructure: Architect and implement test frameworks and infrastructure, and make architectural decisions about test design patterns and abstractions.

- Drive quality strategy: Design testing strategies for new features and platform capabilities, and integrate testing earlier in the development lifecycle through cross-team collaboration.

- Optimize & maintain: Refactor and optimize existing test suites for maintainability and performance, and improve CI/CD pipeline performance and test execution times.

- Manage environments & tooling: Build and manage AWS-based test environments, and develop custom tooling and reporting to surface quality insights.

- Mentor: Mentor SDET I engineers and conduct technical code reviews.

WHAT YOU'LL NEED

- Test automation & frameworks: Extensive Playwright experience (including deep knowledge of fixtures architecture), object-oriented test framework design with layered patterns (PCOM/POM) and scalable abstractions over linear scripts, and API testing/orchestration (REST/GraphQL integrated with UI workflows).

- TypeScript & software design: Advanced TypeScript (generics, decorators, advanced typing patterns, type inference), deep understanding of asynchronous programming, concurrency, and race-condition prevention, and strong software design principles including domain-driven design and patterns (Factory, Builder, Facade, Composite).

- Infrastructure & DevOps: Hands-on AWS (EC2 configuration, CloudWatch log analysis, debugging cloud environments), Docker (containerization, docker-compose, image management), CI/CD debugging and optimization, with Terraform a plus.

- Version control: Expert-level Git, GitHub, and distributed version control workflows.

- Reporting & tooling: Advanced reporting (Allure, Playwright HTML reports, custom solutions), test infrastructure and framework architecture, performance optimization at scale, and npm ecosystem/package management.

COMPENSATION AND BENEFITS

- Compensation: Top of market salary + bonuses and equity

- Time off: 49 days paid time off

- Benefits: PTO, full benefits, retirement and wellness plans.
