MetaCrew
GotoX Vietnam (operated by METACREW). GotoX runs VibeX (vibe-x.app) — one of the world's top-tier vibe coding platforms that generates documents, slides, detail pages, and web apps from a single natural language prompt. TalkX, our AI-assistant-powered messenger, is launching soon. We operate across USA, Korea, and Vietnam as a global AI company.
We don't just use AI — we work with AI as a teammate. Armed with Claude, Gemini, and our own VibeX, each person here creates the kind of impact that traditional teams of ten or more used to deliver.
Role Summary:
KEY RESPONSIBILITIES
App Quality Testing
• Test functionality, UI, responsiveness, performance, and accessibility of apps generated from diverse prompts
• Cross-browser validation: Chrome, Safari, Firefox, Edge
• iOS and Android device testing across real and simulated environments
• Systematically test edge cases: empty inputs, special characters, boundary values, async race conditions
• Evaluate accessibility: screen reader compatibility, keyboard navigation, tab order, ARIA attributes
Bug Reporting & Triage
• Write clear, reproducible bug reports with steps, environment details, expected vs. actual behavior
• Triage issues by severity and business impact — distinguish critical bugs from AI generation limitations
• Identify and flag security vulnerabilities: XSS, input validation gaps, CORS misconfigurations
AI-Powered Test Automation
• Generate AI-powered test cases using Claude, Gemini, or similar tools
• Build regression test scenarios that account for non-deterministic AI outputs
• Develop testing strategies adapted to generative UI — where there is no fixed design spec to compare against
• Automate repetitive validation flows where applicable
Pipeline Feedback & Platform Improvement
• Analyze QA findings to identify systemic patterns in VibeX-generated outputs (e.g., recurring layout breaks at specific breakpoints, consistent logic errors in form handling)
• Translate bug patterns into actionable prompt improvements and generation pipeline recommendations
• Collaborate directly with the VibeX engineering team to feed findings back into model and prompt iteration
• Document and share repeatable QA playbooks with the global team
AI Workflow Innovation
• Continuously discover and integrate new AI tools into your QA workflows
• Develop and refine prompt strategies to reproduce hard-to-replicate AI-generated bugs
• Provide product feedback to the VibeX team based on real testing experience
1. Generous compensation and benefit package
2. Empowering growth and skill mastery.
3. Professional and engaging working environment
MUST-HAVE REQUIREMENTS
Experience
• Proven hands-on track record in web or mobile app QA — you have found, reported, and triaged real bugs in production environments
• Not just internal tools or staging — real products, real users, real impact
• Experience testing both web apps (cross-browser) and mobile apps (iOS / Android)
Technical Foundation
• Basic understanding of HTML, CSS, and JavaScript — able to read code, inspect DOM, and trace layout or logic issues
• Familiarity with browser DevTools for network, console, and element inspection
• Understanding of fundamental web concepts: HTTP requests, API calls, async behavior, responsive design
AI Capability (Critical)
• Daily, hands-on user of AI tools — for test case generation, documentation, and workflow automation
• Able to demonstrate at least one real piece of QA or technical work produced primarily with AI
• Strong prompt engineering instinct: you know how to get AI to generate useful, specific, and structured test cases
• AI capability is our #1 hiring criterion — more important than years of experience
Language
• English: Able to read and write technical documentation, bug reports, and test cases (required). Speaking proficiency is a plus but not mandatory.
• Japanese or Chinese proficiency is an advantage
Mindset
• Detail-obsessed without losing sight of the big picture — you catch bugs others miss, but always ask "does this matter?"
• Self-disciplined with a strong sense of ownership and responsibility
• Fast iteration: bias toward shipping test cycles quickly, learning, and refining
• Pioneer mindset: thrive in uncharted territory where you co-build the QA playbook with the team
NICE TO HAVE
• Experience testing SaaS, dev tools, or AI-generated products
• Familiarity with vibe coding / no-code platforms (VibeX, v0, Lovable, Bolt, etc.)
• Prior startup or solo project experience where you owned QA end-to-end
• Experience with automation frameworks (Playwright, Cypress, Selenium)
• Background in accessibility testing (WCAG standards)
• Understanding of prompt engineering and how LLMs generate UI/code
What to Submit:
1. Your résumé (PDF preferred)
2. One thing you have built or tested with AI — automation, test case, bug report, script, or any real work that shows how you use AI in practice
Important note: AI capability is the #1 hiring criterion. What you have built and tested with AI matters more than your résumé. Show us the work — that's what counts.
HIRING PROCESS
Step 1 — Application Review: We review your application and get back to you promptly.
Step 2 — Pre-Interview
Assignment
Upon shortlisting, you receive a free VibeX Pro plan and two assignments to complete and submit before the interview. One assignment will involve building and testing a VibeX-generated app. This is not just a test — it's your chance to experience what working at GotoX actually feels like.
Step 3 — Interview We will discuss your assignment, your AI workflow, and real bug cases you have found and resolved.
Step 4 — Decision We will communicate the outcome after the interview.
