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.
