Senior QA Engineer

At TechBiz Global, we are providing recruitment service to our TOP clients from our portfolio.

We are currently looking for a dedicated Senior Quality Engineer to join one of our clients' teams. If you're looking for an exciting opportunity to grow in an innovative environment, this could be the perfect fit for you.

Responsibilities:

Ending customer-reported bugs / by building an internal safety net that catches critical issues before release

• Triage and reproduce incoming bug reports, and trace issues across logs, API calls, and session replays

• Test features in active development and run a regression suite before every release

• Establish QA sign-off as a standard part of the release process

Building the quality infrastructure from scratch / by defining the strategy, automation, and processes the team currently lacks

• Define the testing strategy, standards, workflows, and documentation from the ground up

• Design and implement an automation framework covering UI, API, and regression suites

• Incrementally grow automated coverage of the highest-risk flows without disrupting delivery

Making quality a shared team capability / by embedding QA thinking across the development lifecycle

• Track and report quality metrics so reliability is visible to the whole team

• Translate customer bug reports into actionable test cases and durable coverage

• Bring quality into requirements and design, not just release sign-off

• Experience as the first or only QA engineer at a company or within a team - you have built a QA function from scratch, not inherited one

• Experience testing complex third-party integrations (REST/SOAP APIs, external data providers, or similar) where your application depends heavily on responses you don't control

• Experience shipping test automation from zero - not just maintaining an existing framework

• Strong hands-on manual and exploratory testing skills across functional and regression testing for web applications

• API and integration testing depth, including edge cases, error handling, data mapping, and contract validation between systems

• Defect management and root-cause analysis - disciplined bug reporting, triage, prioritisation, and driving fixes for recurring issues rather than surface patches

• Regression risk assessment - the judgement to define what "safe to ship" looks like for a given release

• Cross-functional collaboration - working with developers, product, and customer-facing teams, and advocating for quality without slowing the team down

• Awareness of the travel / Global Distribution System domain (e.g. booking flows, PNRs, fare rules, availability) is a strong plus - enough to avoid the test-coverage blind spots a generic QA engineer would miss

• Experience or interest in early-stage or growth-stage startups, and comfort building structure in ambiguity

• Fluency in English. Other languages are a plus.
