Identify, document, and track bugs and system weaknesses, partnering with engineering teams to improve QA processes, automation coverage, and testing standards.
4+ years of experience in QA Automation, including designing and maintaining automated testing frameworks.
Strong proficiency in Python or JavaScript/TypeScript for building and maintaining automation scripts and test frameworks.
Experience with automation tools such as Cypress, Playwright, Selenium, or similar testing frameworks.

Hands-on experience working with CI/CD pipelines and containerized environments (Docker).
Strong verbal English communication skills.
Availability to work and collaborate during EST (Eastern Standard Time) hours.
Preferred Qualifications
