The full form of SDET is Software Development Engineer in Test.

A “Software Engineer in Test” (a.k.a. “Software Development Engineer in Test”) is a software developer who develops software for testing: tools, frameworks, and automated tests. SETs focus primarily on automation for running tests quickly and repeatedly. Test automation is a software product: just as front-end developers write web pages and back-end developers write microservices, SETs write automated tests. The same practices and coding skills apply. I frequently say that a Software Engineer in Test must have the heart of a developer.

Imagine being a part of a small, agile team where your ideas have the potential to reach millions within a matter of months. Picture working on cutting edge consumer-facing products, where every single team member is a critical voice in the decision-making process. Envision being able to leverage the resources of a Fortune-500 company within the atmosphere of a start-up. Welcome to Amazon Music, where ideas are born, and come to life as Prime Music, Music Unlimited.

Everyone on our team has a meaningful impact on product features, direction, and delivery. We are looking for new team members across a variety of job functions including software engineering/development, marketing, design, ops and more. Come join us and make history by launching exciting new projects in the coming year. The QA group is responsible for testing the software produced by this group as well as the overall health of our software in production. Our teams of Software Developers in Test are engaged at automating our testing process and building tools that allow us to efficiently test and monitor the health of our software. Our Software Development Engineers in Test (SDETs) leverage open source technologies as well as tools developed in-house to improve coverage and lower defect rates.

SDETs at Amazon are able to understand software internals, debug code, automate repetitive tasks, and implement new tools and frameworks needed to streamline our quality process. Our SDETs work directly with both Software Development Engineers and Quality Assurance Engineers to understand project features, review technical designs, and implement automated test tools that help deliver quality features with efficiency. Our SDETs understand customer usage models and are able to develop test plans and test cases that approximate real-world environments and scenarios.

A Software Development Engineer in Test (SDET) is a developer with the primary responsibility of writing frameworks and tools to test products. It is a very unique and challenging role and provides immense opportunity to design and develop wide-reaching tools. It combines the “building” aspect of software design engineering with the “breaking” aspect of software test engineering. You’ll be writing code that automatically verifies the quality of the product. That means that you potentially write more code than the developers.
