What does a QA engineer do?

A QA engineer makes sure software works as intended before it reaches users: they plan tests, check features manually, write automated tests and report defects clearly. Good QA engineering lets a team release more often with fewer bugs in production.

DevKit QA engineers cover both manual and automation testing for web, mobile and APIs, with Cypress, Playwright, Selenium, Postman and Jest. Every one of them passes a technical interview with our senior engineers before you see their CV.

When to hire one

  • Setting up a QA process for a team that has none
  • Automating regression tests that are run by hand today
  • Adding test coverage before a major release or migration
  • Testing APIs, integrations and mobile apps across devices

What our QA engineers do

Typical work our QA engineers take on for clients.

Test strategy and planning

Test plans, test cases and acceptance criteria that match your release process.

Manual and exploratory testing

Functional, regression and usability testing that finds what scripts miss.

UI test automation

Stable end-to-end test suites in Cypress, Playwright or Selenium that run on every build.

API testing

Automated checks of REST and GraphQL APIs with Postman, REST Assured or code-based tests.

Mobile testing

iOS and Android testing on real devices and emulators, manual or automated with Appium.

CI/CD integration and reporting

Tests wired into your pipelines with clear reports, so failures are caught and fixed early.

Matched to your budget: which level do you need?

We match the level to the work, so you don't pay senior rates for tasks a mid-level engineer handles well, or put critical work on the wrong hire.

Junior

Well-defined tasks with guidance

Bug fixes, tests and smaller features in an established codebase, with a senior on your team to review their work. The most budget-friendly option.

Mid-level

Independent feature work

Builds features end to end in an existing architecture with little supervision. The best value for most product teams.

Senior

Complex features and ownership

Owns complex parts of the system, makes sound technical decisions and mentors others. Worth it where mistakes are expensive.

Tech lead / Architect

Architecture and team leadership

Designs the system, sets standards and leads other engineers. Ideal for new products, rewrites or a team without technical leadership.

Hiring QA engineers: FAQ

How quickly can I hire a QA engineer through DevKit?

You usually receive vetted QA CVs within 3–5 business days, and the engineer typically starts within 2–3 weeks of the first call.

Which testing tools do your QA engineers use?

For automation, mainly Cypress, Playwright and Selenium, with Appium for mobile. For APIs and unit tests, Postman, REST Assured, Jest and Pytest, with test management in Jira, TestRail or Zephyr and tests running in your CI/CD pipeline.

Do I need a senior QA engineer?

Not always. If your test process and automation framework are set and someone senior reviews the work, a mid-level QA engineer often delivers the same results for less. To build a QA process or automation framework from scratch, or to test critical systems, a senior engineer or QA lead is usually worth it. We'll recommend the right level on a free call.

How much does it cost to hire a QA engineer?

Staff augmentation is billed as a monthly rate per engineer, depending on the level and whether you need manual or automation testing. Tell us your budget and we'll match QA engineers to it; exact rates come with the first CVs.
