Software Development Engineer in Test

Software Development Engineer in Test

Overview

We are looking for a highly capable Software Development Engineer in Test (SDET) who operates at the intersection of quality and engineering. This role goes beyond traditional QA and requires hands-on contribution to the codebase, strong automation expertise, and a deep understanding of system behavior through white box testing.

Key Responsibilities

• Partner closely with engineering teams to ensure quality is built into the development lifecycle
• Contribute directly to the codebase, including development of unit tests and test frameworks
• Design and implement scalable, maintainable test automation across front-end and API layers
• Develop mocks and stubs to support isolated and deterministic testing
• Conduct white box testing with a strong understanding of application logic and architecture
• Drive integration and contract testing to ensure system reliability across services
• Leverage BrowserStack and similar platforms for comprehensive mobile and cross-browser validation
• Continuously evaluate and improve test coverage, execution speed, and overall quality practices

Technical Requirements

• Strong proficiency in JavaScript or TypeScript with hands-on experience using Playwright for front-end automation
• Solid experience with Golang, particularly in API development, unit testing, and integration testing
• Proven ability to work within application codebases, not limited to external test layers
• Experience building mocks, test harnesses, and reusable testing utilities
• Deep understanding of white box testing principles and modern testing strategies
• Familiarity with contract testing and service-level validation

What We Are Not Looking For

• Manual testers without automation or coding experience
• Candidates focused solely on writing basic automation scripts without system-level understanding

What Success Looks Like

• High-confidence releases supported by strong automated test coverage
• Meaningful contributions to both product code and test frameworks
• Improved testing efficiency, reliability, and scalability across the stack
• Strong alignment with engineering teams and proactive ownership of quality outcomes
