Performance, Stress & Heavy Load Testing\nDesign, script, and execute load, stress, spike, and endurance tests using tools such as Grafana k6, Apache JMeter, Gatling, or Locust.\nSimulate heavy production B2B traffic patterns: thousands of concurrent users searching large product catalogs, filtering complex attributes, uploading bulk media to AWS S3, and submitting Requests for Quotations (RFQs).\nCollaborate with Backend (Node.js/Express) and DevOps (AWS ELB, NGINX, DocumentDB) teams to identify bottlenecks, slow database queries, memory leaks, and server concurrency limits.\nEstablish performance baselines and SLA thresholds (Response Time, P95/P99 latency, Throughput/RPS, Error Rates).\n2. Web Browser Test Automation\nBuild, maintain, and scale End-to-End (E2E) cross-browser automation frameworks using Playwright (preferred) or Cypress / Selenium with TypeScript/JavaScript.\nAutomate critical cross-application B2B workflows spanning our three React web platforms:\nBuyer Website: Search, multi-tier pricing/MOQ calculations, RFQ submission, OAuth login, and checkout flows.\nSupplier Dashboard: Product creation, image cropping/uploads, inventory updates, and order management.\nAdmin Portal: Supplier KYC verification, catalog moderation, and role-based access control (RBAC).\nValidate multi-language localization (i18n) and RTL/LTR layouts (Arabic & English) across desktop and mobile web viewports.\n3. Native Mobile Application Automation (iOS & Android)\nArchitect and maintain automated UI and regression test suites for our Native iOS (Swift/SwiftUI/UIKit) and Native Android (Kotlin) applications using Appium, Maestro, XCUITest, or Espresso.\nAutomate mobile-specific features including push notifications (FCM), camera/QR barcode scanning, offline caching (Core Data / Room), geolocation/maps, and deep linking.\nExecute automated tests across real device clouds (e.g., BrowserStack, AWS Device Farm, Sauce Labs) as well as local Xcode Simulators and Android Emulators.\n4. API & Integration Testing\nTransition manual Postman collections into automated API test suites using Newman, Playwright API, RestAssured, or SuperTest.\nValidate RESTful API contracts, JSON schemas, status codes, JWT authentication, session security, and edge-case error handling.\nTest asynchronous and third-party integrations (Google Cloud Vision/Translation APIs, AWS S3 uploads, email/push notification triggers).\n5. QA Process & CI/CD Integration\nUpgrade our test management workflow from spreadsheets (Excel/Google Sheets) to structured Test Management tools integrated with Jira (e.g., Xray, Zephyr, or TestRail).\nIntegrate Web, Mobile, API, and Performance test suites directly into CI/CD pipelines (GitHub Actions / GitLab CI) to enforce quality gates on every pull request and release\nRequirements\nRequirements & Qualifications\nMust-Have Technical Skills:\nExperience: 3–6+ years of hands-on experience in QA Automation, SDET, and Performance Testing for high-traffic web and mobile applications.\n\nPerformance & Load Testing: Proven track record of conducting heavy load and stress testing on production-grade APIs and web platforms using k6, JMeter, or Gatling, with the ability to analyze server/database metrics and generate actionable diagnostic reports.\n\nWeb Automation: Strong proficiency in Playwright or Cypress (using TypeScript or JavaScript) testing modern Single Page Applications (specifically React.js and UI libraries like Tailwind CSS and Ant Design).\n\nMobile Automation: Hands-on experience automating native iOS and Android apps using Appium, Maestro, or native frameworks (XCUITest / Espresso), including configuring Xcode and Android Studio test environments.\n\nAPI Testing: Deep expertise in Postman, REST API architecture, HTTP protocols, Authentication (JWT, OAuth2), and automated API testing tools (Newman or code-based frameworks).\n\nQA Fundamentals: Mastery of STLC, Bug Life Cycle, Boundary Value Analysis, Equivalence Partitioning, and Decision Table Testing.\n\nTooling: Proficiency with Git/GitHub, Jira, and Chrome DevTools (network inspection, payload debugging, and frontend performance profiling).\n\nNice-to-Have (Bonus) Skills:\nPrior experience testing B2B or B2C E-Commerce Marketplaces (multi-vendor workflows, complex catalogs, bulk Excel/CSV imports, payment gateways).\n\nFamiliarity with Node.js, MongoDB / Amazon DocumentDB, and AWS infrastructure (EC2, ELB, S3, CloudWatch) to help diagnose backend bottlenecks during load testing.\n\nExperience with Security / DAST testing tools such as OWASP ZAP or Burp Suite (testing for broken access control/IDOR, XSS, and rate-limiting).\n\nExperience testing Arabic/English (RTL/LTR) interfaces.\n\nWhat We Offer\nThe opportunity to architect and own the entire Automation and Performance QA strategy for a high-growth B2B marketplace ecosystem.\n\nA modern tech stack (React 19, TypeScript, Node.js, Native Swift & Kotlin, AWS Cloud).\n\nCompetitive salary and career growth into a QA Architect / Lead SDET role.","description_format":"text","description_chars":5831,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Egypt","iso":"EG","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Marketplaces"],"lifecycle":[{"event":"open","at":"2026-11-09T14:42:35Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring
