About the Role
The Sr. Performance Software Development Engineer in Test engineer will work in a highly collaborated agile environment across all stages of the software development cycle. This role involves architecting, designing, building test and executing performance and automation solutions to enhance the quality of our products.
The ideal candidate for this role will possess a deep expertise in object-oriented design principles, test automation design patterns, performance, KPIs and best practices to improve testability of complex integration systems to reduce manual test execution, accelerate test efficiency and ensure optimal performance of our products.
