Working location: Sai Gon Ward (District 1), HCMC
Salary range: Up to VND 60,000,000 gross
RESPONSIBILITIES
We're hiring an Automated Test Engineer to own test automation across our web and mobile products. Mobile is a major focus: native iOS (Swift), native Android (Kotlin) and cross-platform React Native. You'll be equally capable on web builds, creating the frameworks and pipelines that let product teams ship confidently on every platform.
You'll be the quality engineering voice in a cross-functional squad, turning acceptance criteria into automated checks that run on every commit and every build. On web, that means reliable end-to-end, cross-browser and API coverage. On mobile, you'll understand how each platform behaves (lifecycles, permissions, offline states, push notifications, deep links and device fragmentation) and test for it.
Our stack is Swift and Kotlin on mobile, TypeScript across web and React Native, Java on the backend, and a Ruby product we also manage, all hosted on AWS with Terraform for infrastructure as code. End- to-end testing runs on Maestro, coverage is tracked in Codecov, and we build with AI using Anthropic's Claude and GitHub Spec Kit for spec-driven development. Expect to shape the test strategy across all of it, not just execute it.
● Own and grow our Maestro end-to-end suite, using Maestro Studio to build and maintain flows for iOS, Android, React Native and web
● Write lower-level mobile UI tests in XCUITest (Swift) and Espresso or Compose UI Test (Kotlin) where Maestro isn't the right fit
● Turn Spec Kit specifications and acceptance criteria into automated tests, and use Claude to speed up test design and generation
● Automate API and integration tests for our Java backend services and Ruby product
● Work with
developers on unit tests and track coverage in Codecov, setting sensible thresholds and closing gaps
● Integrate suites into CI/CD pipelines with clear reporting on every build
● Help provision and maintain test environments on AWS using Terraform
● Run tests across browsers, real devices and simulators, including cloud device farms
● Test mobile-specific behaviour: OS versions, screen sizes, permissions, background / foreground, network loss, push notifications and deep links
● Check performance and accessibility on web (Lighthouse, axe, WCAG) and mobile (startup time, memory, VoiceOver, TalkBack)
● Investigate failures, reduce flaky tests and keep suites fast and trustworthy
● Support release quality for web deployments and TestFlight, App Store and Google Play submissions
● Test AI features built on Anthropic's models, including evaluation sets and guardrail checks
● Report on quality metrics such as Codecov coverage, defect leakage, crash-free rate and pipeline stability
REQUIREMENTS
● 3+ years in test automation or software development in test across web and mobile apps, with substantial mobile experience
● Strong TypeScript, working Swift and Kotlin, and enough Java and Ruby to read and test backend code
● Hands-on native test automation with XCUITest/XCTest on iOS and Espresso or Compose UI Test on Android
● Hands-on end-to-end automation with Maestro (including Maestro Studio) across mobile and web, or strong Detox, Appium or Playwright experience and keenness to move to Maestro
● API testing with Postman, REST Assured or Pact
● Comfortable using AI in your daily work, ideally Claude, and working from specs in a spec-driven workflow such as Spec Kit
● Experience running web and mobile tests in CI/CD (GitHub Actions, Bitrise, Xcode Cloud or fastlane), on browser and device farms, with coverage reporting in Codecov, and working with Git
● Solid grasp of web and mobile testing challenges (cross-browser issues, device fragmentation, OS versions, app lifecycle, offline states) and the test pyramid
● Comfortable in Agile teams, working closely with developers and
product owners
● Clear communicator who can explain quality risks to technical and non-technical people
Desirable:
● AWS experience, and Terraform for spinning up and tearing down test environments
● Backend testing in Java (JUnit, Testcontainers) or Ruby (RSpec)
● Has shipped production features in Swift, Kotlin or React Native, not only tested them
● Performance testing with k6, JMeter or Gatling, and mobile profiling with Xcode Instruments or Android Studio Profiler
● Experience testing LLM-based features
● Consulting or client-facing delivery experience
● ISTQB or similar certification
