Software Development Engineer in Test - SDET

Certa is an AI-first third-party operating system. As an SDET II, you will own test infrastructure and drive quality strategy across the engineering team, designing testing approaches for complex features and mentoring junior engineers.

• 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.

• 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: Top of market salary + bonuses and equity
• Time off: 49 days paid time off
• Benefits: PTO, full benefits, retirement and wellness plans.
• Growth: Professional development support, remote workspace setup bonus.
• Team building: Annual company offsites in exciting locations around the world
