Software Development Engineer in Test - SDET

Overview

Own significant parts of Certa's test infrastructure and drive quality strategy across the engineering team as an SDET II.

What you'll do

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

What you'll need

• 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.
• API testing/orchestration (REST/GraphQL integrated with UI workflows).
• Advanced TypeScript (generics, decorators, advanced typing patterns, type inference).
• Deep understanding of asynchronous programming, concurrency, and race-condition prevention.
• Strong software design principles including domain-driven design and patterns (Factory, Builder, Facade, Composite).
• Hands-on AWS (EC2 configuration, CloudWatch log analysis, debugging cloud environments).
• Docker (containerization, docker-compose, image management).
• CI/CD debugging and optimization.
• Expert-level Git, GitHub, and distributed version control workflows.
• Advanced reporting (Allure, Playwright HTML reports, custom solutions), test infrastructure and framework architecture, performance optimization at scale, and npm ecosystem/package management.

Nice to have

• Terraform.
