Senior QA Engineer - Mobile & AI Backend Quality

Axis Global Tech Limited; Hong Kong; On-site; HKD 600,000 - 900,000; Full time

Job summary

Axis Global Tech Limited seeks a Senior QA Engineer to own quality across a consumer product and its backend services. The role covers a React Native mobile app, a Next.js web app, serverless backends using AWS Lambda, and an authentication service.

You will drive release criteria, test AI features, ensure security paths, and exercise schema migrations across environments. You will define and enforce quality gates, audit PRs for test coverage, report defects precisely, and push back early on

Qualifications

• Four or more years testing mobile and web applications, with at least two on React Native or another cross-platform stack, on both iOS and Android.
• Hands-on API testing of REST and streaming endpoints, including authentication flows with bearer tokens and JWTs.
• Experience writing automated tests in TypeScript. You can read the code you are testing and write or repair a unit test.
• Working knowledge of SQL and of testing schema migrations against a live database.
• Comfortable with the AWS console and CLI at the level of reading CloudWatch logs, invoking a Lambda function and inspecting a CloudFront distribution.
• Git and GitHub pull-request workflow. You review test changes in PRs and keep CI green.
• Clear written English. Your reports and test plans are read by engineers and by leadership.

Responsibilities

• Decide what a release has to pass before it ships, write that down, and run it. Sign off on mobile releases and backend deployments, or document why a release went out without sign-off.
• Evaluate the behaviour of the AI features. Maintain a baseline of expected behaviour, run changes against it, judge the results, and turn each miss into a reproducible report an engineer can act on.
• Test authentication and security paths: rate limits, expiry, token lifetimes, key rotation, replay and enumeration attempts, and transport requirements.
• Test data changes. Exercise schema migrations against a local database stage on existing data and from a clean install before they reach a shared environment.
• Measure what matters. Where a number bounds something a user can feel, such as latency to first response, push delivery time or cold-start time, measure it and record how.
• Report defects precisely: reproduction steps, build or commit, stage, expected and observed behaviour, and severity. Reproduce before filing.
• Review pull requests for testability and for missing or weakened tests, and push back when coverage is claimed but not present.
• Raise quality risks early, in writing, with a proposed mitigation.
