Software Development Engineer in Test

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.

Responsibilities:

• 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.
• Optimise and maintain: Refactor and optimise existing test suites for maintainability and performance, and improve CI/CD pipeline performance and test execution times.
• Manage environments and 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.

Requirements:

• Test automation and 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 and 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 and DevOps: Hands-on AWS (EC2 configuration, CloudWatch log analysis, debugging cloud environments), Docker (containerization, docker-compose, image management), CI/CD debugging and optimisation, with Terraform a plus.
• Version control: Expert-level Git, GitHub, and distributed version control workflows.
• Reporting and tooling: Advanced reporting (Allure, Playwright HTML reports, custom solutions), test infrastructure and framework architecture, performance optimisation at scale, and npm ecosystem/package management.
