With automation set to play an ever growing part of IT industry, an understanding of SDET will be essential for keeping up with industry demand.

What is Software Development Engineer in Test (SDET)?

Software Development Engineer in Test (SDET) is a unique engineering role which bridges the gap between software development and software testing.


This role integrates professional knowledge of software engineering practices with comprehensive knowledge of automation testing, bridging the gap between software developer and tester.

By merging both roles together, one is able to develop an automation workflow which speeds up the development process immensely.

SDET bridges these seemingly disparate roles into a cohesive unit that can deliver quality automation solutions quickly and efficiently.


It requires technical knowledge to construct automation testing framework, leveraging tools such as selenium webdriver to create robust automation tests.

The SDET must possess an advanced understanding of the product and be able to test the product for functionality, security and performance.

As automation becomes more prevalent in software engineering, the role of the SDET will become ever more important, ensuring that automation tests are up-to-date and effective in verifying quality products for release.


Why become a Software Development Engineer in Test (SDET) Professional?

Becoming a SDET is an impressive career with huge potential.

According to Glassdoor, the average salary for an SDET position in the US is $112193 per year as of January 2023.

It’s no wonder so many technology professionals are pursuing IT roles; working as an SDET provides expertise in these areas and also offers a high-paying job.

Being an SDET means having access to great business opportunities such as working for cutting-edge technology companies, using ground-breaking automation tools and becoming a leader or innovator in the industry.


It isn’t just about the salary – it’s about creating real value, solving problems and pushing boundaries by developing unique automation solutions.

Whether you’re just starting out or already have experience in this field, pursuing a career as an SDET is definitely worth considering.

The software testing field is a rapidly expanding one, with the market size being valued at USD 40 billion in 2021 and an anticipated Compound Annual Growth Rate of 6% over the course of the 2022-2030 period.


This potential for growth has come as automation testing – both artificial intelligence (AI) and Selenium automation – have become increasingly more viable for major companies seeking to improve their development and test automation processes.

Given this landscape, System Development and Test Engineers (SDETs) are now more apt than ever to use automation testing as a tool in their critical work.

In keeping up with this trend, test automation has quickly become a sought after skill among those looking to break into the industry or transition into other related roles like software tester, test automation engineer, qa automation engineer, software engineer, QA tester, and of course SDET specialist.


An Overview of the Roles & Responsibilities of SDET Professionals

  1. SDET is a professional specializing in automation and software testing, development of software, and tools such as Selenium WebDriver.
  2. SDET engineers create automation frameworks and scripts that can assess and validate the quality of software before it is released.
  3. SDETs are responsible for debugging automation processes, creating test plans and scripts, executing tests, and preparing reports to keep stakeholders informed on the product’s progress.
  4. Given the highly technical nature of automation testing, SDETs require a clear understanding of automation framework, software automation engineering concepts and techniques.
  5. The role of a SDET engineer combines knowledge from various disciplines such as mathematics, statistics, and scripting techniques – making them indispensable for ensuring top-notch software quality throughout the entire development process.
  6. SDETs are responsible for ensuring the quality of automation and software testing within software development process. They have the responsibility of testing software automation, both with manual testing and automation testing.
  7. Not only is the automation process essential for the development phase, but SDET professionals are also required to verify the accuracy with more complex testing such as automation frameworks, automated coding, and integration systems as well as using automation tools such as Selenium web driver and Cypress to write and execute automation test cases, different test scenarios, and develop automation testing frameworks.
  8. They also build test automation tools and create test automation frameworks that make it much easier and more reliable to test specific applications.
  9. This role requires strong technical knowledge, and experience in automation development, operating systems, and databases. The primary responsibilities of this position involve setting up automation test environments, researching automation best practices, instrumenting automated tests as well as executing existing automation scripts to uncover bugs.
  10. SDET professionals must actively collaborate with developers, quality control analysts, and other stakeholders within the software development process to ensure adherence to service level agreements and agreed-upon requirements.
