    Title: Java - SDET Duration: 3 yrs SDET ROLE Let me be very clear here - these are NOT traditional QA roles. I.e. Selenium-only or QTP/UFT-only guys who are QA Engineers. Instead, I'm talking about heavy-duty Java Engineers who happen to build internal tools/products for the purposes of testing rather than products that are used externally. In short, they need Java Engineers who have a passion for, and professional interest in, Quality. Engineers must be able to write code to the same standard as a typical Engineer. Use standard notation, design principles, data structures and algorithms, etc. They must be 100% competent and not guys who can only hack away at code. They need to be excellent communicators as they will be reviewing Pull Requests, analyzing another Engineer's code, fixing said code and providing detailed feedback as to what the Engineer needs to do differently so that their next Pull Request is free of defects. They will be building internal tools for testing purposes and, of course, performing automated testing. When it comes to Test Automation, we need expertise in Test Automation using hand-built frameworks, test beds/harnesses engineered in Java. Must have expertise in building said automation frameworks in addition to writing & executing test cases Expertise in the automated testing of Web Services, APIs, API Gateways. Expertise in Microservices testing is a huge added bonus Additional Information All your information will be kept confidential according to EEO guidelines.
