Our social-media app is almost ready for release, and I need a hands-on test engineer in Bangalore who can sit with the product and dev teams and give the build a rigorous, end-to-end workout. Scope • Create all test artefacts from scratch––test strategy, detailed test cases, data sets, and an execution calendar. No legacy scripts exist. • Cover three angles: functional flows, back-end performance under realistic load, and a baseline security sweep. • Run every scenario on both iOS and Android builds produced from our single Flutter codebase. • Log issues clearly in Jira (or a comparable tracker), retest fixes, and keep concise daily status updates. Tech environment Frontend: Flutter Backend: Node.js (Express) Database & hosting: DigitalOcean droplets + managed DB Typical tools that fit well here include Postman, Charles/Fiddler, JMeter or k6 for load, and OWASP ZAP/Burp for quick security passes; if you prefer equivalents, that is fine as long as results are reproducible. On-site collaboration Face-to-face interaction speeds up triage, so plan to work from Whitefield, Bangalore. Acceptance criteria • Complete, reproducible test suite delivered in Excel, Google Sheets, or Zephyr. • All critical paths show zero blocker/high-severity defects. • Performance report documenting peak, average, and threshold metrics with recommendations. • Security checklist with findings and suggested fixes. • Final sign-off memo summarising overall quality and release readiness. If this matches your skill set and you can start quickly in Bangalore, let’s talk.
