Web/App Test Engineer
Role Overview
Responsible for end-to-end quality assurance across Web and App (mobile) surfaces — combining automated and exploratory testing to ensure product stability, compatibility, and interaction experience from the user's perspective. The core requirement is cross-platform testing capability (Web + App), with the ability to design and maintain an automated testing system and to think deeply about troubleshooting and user-experience-oriented quality.
In one sentence: This role is the quality gatekeeper for Web/App products — someone who can write automation scripts, test interaction experiences, investigate data issues, and use engineering methods to replace manual testing with systematic automated quality coverage. Not a manual tester — a QA engineer with real coding ability.
Key Responsibilities
- Design and maintain comprehensive Web/App test cases and test plans covering functionality, compatibility, and interaction
- Develop and maintain UI/API automated tests using Java, Python, or JavaScript to ensure high coverage and reliability
- Combine automation and manual exploratory testing to validate user scenarios and discover potential experience issues
- Perform root cause analysis on test failures and production issues, and drive fixes to closure
- Identify blind spots in test coverage and continuously improve automation effectiveness
- Participate in testing for new features — define expected behaviors, system impact, and risk points from a user-experience perspective
- Conduct App compatibility testing across devices, OS versions, and screen sizes, as well as Web cross-browser and cross-resolution testing
- Participate in performance testing (page load time, App cold start / warm start, etc.) and ensure stability under high-concurrency and weak-network scenarios
Requirements
- Strong coding ability in at least one of Java, Python, or JavaScript (live coding assessment required)
- Extensive Web/App automation testing experience with tools such as Selenium, Appium, Playwright, etc.
- Solid understanding of Web/App testing methodologies and automation framework design
- Proficiency in SQL for data validation and issue troubleshooting
- Proven root cause analysis ability to solve complex quality problems
- Familiarity with Web front-end technologies (HTML/CSS/JS) and mobile platform fundamentals (Android/iOS architecture and characteristics)
- Experience building testing tools, platforms, or quality infrastructure
Ideal Candidate Profile
Background:
- 1–5 years of QA or test development experience, including at least 1 year of Web or App automation testing
- Strong coding skills — able to write code from scratch, not just scripts
- Proficient in SQL for independent data validation and troubleshooting
- Hands-on mobile or Web testing experience
- Automation capability: Can design and develop automation frameworks, not just use existing tools
- Root cause analysis: Can trace test failures or production issues back to their root cause
- SQL & data validation: Can write complex SQL to verify data consistency and troubleshoot data-related bugs
- Cross-platform understanding: Understands Web/App architecture, including front-end/back-end interaction, network requests, cache mechanisms, and WebView
- UX sensitivity: Can identify experience issues from the user's perspective, not just whether functionality works
- Test tooling: Experience building test platforms, tools, or quality infrastructure
- Collaboration drive: Can push developers to fix issues rather than passively waiting
Soft Skills:
- Rigorous and detail-oriented
- "Destructive thinking" mindset — adept at finding system weaknesses
- Strong communication — bridges developers and product managers
- Quality ownership mentality — treats quality as personal responsibility
Bonus Points
- Payment, transaction, or financial system QA experience
- AI tooling usage experience
- Crypto / Web3 industry background
- Hands-on App compatibility testing experience using cloud device platforms such as Testin or WeTest
- Weak-network testing experience using tools such as Charles or Fiddler
What does a JavaScript developer in web3 do?
A JavaScript developer in web3 would likely be responsible for developing applications and other software using the JavaScript programming language within the web3 ecosystem
Web3 refers to the third generation of web technology, which emphasizes the use of decentralized technologies such as blockchain and distributed ledger systems
This means that a JavaScript developer in web3 would need to be familiar with these technologies and how to use them in the development of applications and other software
They may also be responsible for maintaining and updating existing web3 applications, as well as working with other members of a development team to create new web3 applications.
