QA Engineers vs. SDETs: Understanding the Differences

::: @figure {QA Engineer vs SDET: Roles, Skills, Salaries and Tools Comparison}

Before bringing someone onto your team, it’s important to understand the specific roles of QA Engineers and SDETs. Despite the occasional overlap in job titles, these roles are distinct. They differ in what they create and how they fit into your testing strategy. Knowing these differences can help you craft better job descriptions and evaluate candidates more effectively.

What QA Engineers Do

QA Engineers are the "end-user advocates" of the software world. They manually test products, often stepping into the shoes of the user to uncover bugs and issues that automated tools might miss. Their work includes exploratory testing, usability checks, and identifying edge cases. While some QA Engineers dabble in automation with tools like Selenium, their primary focus is ensuring the product meets quality standards from a user's perspective.

Rather than building tools, QA Engineers typically rely on existing ones. They use test management software, bug tracking platforms like Jira, and automation tools such as Selenium or Postman. Their coding skills, if used, are aimed at running tests rather than creating testing frameworks. The role demands strong analytical abilities, attention to detail, and a solid grasp of testing methodologies (like black-box or grey-box testing). Ultimately, their value lies in their ability to spot issues that could disrupt or confuse users, such as inconsistent design elements or inaccessible features.

What SDETs Do

SDETs, on the other hand, are the architects of testing systems. They write production-level code to build automation frameworks, libraries, and tools that make testing faster and more reliable. While QA Engineers focus on finding bugs, SDETs work to prevent bugs from ever reaching production. Their role is especially critical in environments where speed and scalability are key, such as Agile workflows and DevOps pipelines.

The technical skill set for SDETs is more demanding. They are proficient in programming languages like Java, Python, or Go and are adept at creating scalable testing frameworks. SDETs also integrate testing into CI/CD pipelines using tools like Docker, Kubernetes, and Terraform. Beyond automation, they enhance production code with features like improved logging and testability hooks, build mock servers, and create reusable libraries.

Amy Reichert, a QA Lead, highlights the dual nature of their role:

Software Development Engineers in Test can also utilise these projects to enhance coding and evaluation skills and gain experience deploying into branches as well.

When hiring SDETs, look for candidates who can think about scaling testing systems and optimizing execution across environments - not just those who can write individual tests. Their expertise in distributed systems, API design, and software architecture makes them essential for building robust testing infrastructure.

Key Differences in Hiring

The salary gap between these roles reflects their distinct skill sets. QA Engineers typically earn between $42,000 and $62,000, while Senior SDETs can command salaries around $125,000, with top-level positions exceeding $220,000 at leading tech companies . This difference underscores the importance of aligning your hiring strategy with your project’s needs.

For fast-paced Agile sprints or continuous deployment, SDETs are indispensable to avoid testing bottlenecks. On the other hand, QA Engineers shine when launching user-facing products that require attention to design, accessibility, and complex user scenarios. Often, having both roles on a team creates a balanced approach - SDETs provide the automation backbone, while QA Engineers ensure no critical user issues slip through the cracks.

Writing Job Descriptions That Attract Quality Candidates

Crafting an effective job description is crucial when hiring for QA Engineers and SDETs. It’s often the first impression your company makes on potential hires, and in a field where 87% of companies struggle to fill QA positions due to skill shortages , standing out is a must. The secret? Clarity and focus.

A great job description should immediately communicate the role's purpose. Instead of just listing tools, focus on the problems the candidate will solve. For example, instead of saying, "Automate tests using Selenium", you could say, "Build quality signals that block risky releases before they reach production" . This approach appeals to candidates who think strategically about their work. For SDETs, make it clear that their role involves embedding quality into the software delivery process, as Rework puts it: "SDETs now architect quality into the entire software delivery pipeline."

When listing required skills, keep it concise. Overloading the description with every possible tool or framework can deter qualified candidates. For QA Engineers, focus on essentials like test planning, defect tracking (e.g., JIRA), API testing (e.g., Postman or REST Assured), and basic automation tools like Selenium or Cypress . For SDETs, highlight skills such as full-stack test automation, framework architecture, CI/CD integration (e.g., Jenkins or GitLab CI), and performance testing tools like JMeter or K6 .

Skills to Include in Your Job Posting

Programming skills are a must for both roles, though the level of expertise differs. QA Engineers should have basic scripting abilities in languages like Java, Python, or JavaScript . SDETs, on the other hand, need advanced coding skills, including a strong grasp of object-oriented programming principles .

Experience requirements vary by role and company size. For mid-level positions, 3–5 years of experience is standard . Startups may seek candidates capable of building testing infrastructure from scratch, while enterprise roles often require familiarity with complex integrations and compliance standards like SOX or GDPR .

The following sections outline how to effectively assess these candidates.

Start with a brief phone interview. Include one simple and one challenging question to quickly gauge their foundational skills .

Initial Screening and Technical Tests

For QA Engineers, focus on their ability to plan tests and prioritize defects. A good way to do this is by asking them to design test cases for a new feature and explain how they would prioritize bugs when resources are limited .

For SDETs, consider live coding exercises where candidates automate a practical scenario, such as testing your company's homepage. Alternatively, assign a take-home task and follow up with a live review to discuss their decisions . During these assessments, the reasoning behind their solutions is just as important as the solutions themselves. Ask them to explain their choices, whether it's about selecting specific selectors, managing flaky tests, or scaling a test suite to handle over 500 tests.

Strong communication is key. Candidates should clearly articulate their thought processes. Often, skills-based testing provides more insight than formal credentials .

Evaluation Criteria: QA Engineers vs. SDETs

The evaluation process varies significantly between these two roles. Here's a quick breakdown of how to assess each:

Role	Skills Assessed	Sample Questions	Tools Tested
QA Engineer	Analytical thinking, defect reporting, test case design	"How do you prioritize bugs when resources are limited?"	Jira, TestRail, SQL, Selenium
SDET	Programming, framework architecture, CI/CD integration	"How would you structure this test suite to support 500+ tests?"	Selenium, Jenkins, Appium, Cypress

This framework helps differentiate the roles and ensures a focused evaluation during interviews.

For QA Engineers, pay attention to their detail orientation, ability to think like an end user, and communication skills - especially their ability to bridge gaps between developers and product managers . Test their familiarity with tools like Jira and TestRail, as well as their understanding of manual and basic automation testing .

For SDETs, go deeper into computer science fundamentals, including data structures, algorithms, and object-oriented programming . Beyond coding, top candidates should have a grasp of networking basics (e.g., TCP/IP and routing), database principles, and system startup processes . As Ingraham notes:

A strong SDET should always be able to defend the decisions they make today, with consideration of the impact of those decisions in the future .

Wrap up the evaluation process with a "work day" simulation lasting 3–4 hours. This hands-on exercise lets you confirm their technical abilities and see how well they fit within your team.

A well-structured onboarding process can make all the difference, reducing the time it takes for new hires to become fully productive while setting them up for success . As ARDURA Consulting puts it:

The key metric is not speed but quality: a tester who is onboarded thoroughly catches more defects than one who is rushed into execution.

Setting Up a 30-60-90 Day Onboarding Plan

Preparation starts before Day 1. Make sure new hires have access to essential tools like TestRail, Jira, code repositories, and CI/CD platforms (e.g., Jenkins, GitHub Actions) to avoid unnecessary delays .

First 30 Days: Begin by laying a strong foundation.

• Week 1: Focus on orientation, product overviews, and setting up the local development environment. Aim for new hires to run their first meaningful test case within hours, not days .
• Week 2: Let them execute existing test cases independently under mentor supervision while learning your bug reporting standards.
• Week 3: Introduce automation frameworks by having them review and modify existing tests, rather than writing new ones.
• Week 4: Assign ownership of a portion of the sprint's testing scope, culminating in writing their first automated test from scratch .

Days 31 to 60: Shift the focus to autonomy. By this phase, new hires should consistently contribute to test automation, handle bug triage, and manage regression testing for specific features.

By Day 90: Expect full productivity. They should proactively identify gaps in test coverage, participate in test planning, and write advanced automation scripts without guidance . A mentor (not their manager) should check in daily during Week 1, transitioning to weekly 30-minute sessions by Week 4 .

Once onboarding is complete, the focus turns to career development and keeping your team motivated.

Retention Through Career Growth and Benefits

A strong start sets the stage for long-term success. Providing clear career progression paths - like moving from QA Engineer to roles such as SDET, Senior SDET, Test Architect, or even Engineering Manager - is crucial .
