Highly experienced Senior QA Engineer to help raise the quality bar across our product and engineering organization.
Someone who can own quality across the full software development lifecycle, partner closely with engineering and product, build scalable testing processes, and help ensure we ship fast without sacrificing reliability.
Responsible for designing and executing testing strategies across complex web applications, identifying risk before it reaches customers, improving automation coverage, and helping create a culture where quality is owned by the entire team.
Strong experience testing full-stack web applications, including frontend, backend, APIs, data flows, integrations, and infrastructure-related behavior
Deep understanding of QA methodologies, test planning, regression testing, exploratory testing, automation strategy, and release management
Strong understanding of JavaScript / TypeScript-based applications and modern frontend frameworks such as React
Experience testing APIs, backend services, authentication flows, permissions, data integrity, and complex user workflows
Ability to read code, review logs, inspect network activity, use browser developer tools, and work closely with engineers to isolate issues
Strong understanding of CI/CD pipelines and how automated tests fit into modern development workflows
Ability to operate independently, prioritize risk, and take ownership with minimal oversight
