About the Role We're building a secure, multi-tenant SaaS platform on Next.js (App Router) and Node.js , deployed natively on the Cloudflare Edge ecosystem (Workers, Pages, D1, R2, KV). We're looking for a QA Tester who is equally comfortable breaking the product by hand and codifying that judgment into automated tests that run in CI . This is not a generic manual-testing or basic-Selenium role. We need someone who understands why edge-deployed, serverless applications fail differently than traditional server-based apps — and who can catch those failures both exploratively and automatically, before they reach production. What You'll Own 1. CI/CD & Test Automation (GitHub Actions) Write and maintain GitHub Actions workflows (.github/workflows) that trigger automated test suites (Playwright, Vitest) on every Pull Request. Manage environment secrets securely and configure staging/preview environments per branch. Build quality gates that block bad builds from deploying to Cloudflare Pages/Workers. 2. Cloudflare Edge Testing & Emulation Write automated integration tests for our serverless environment using Wrangler and Miniflare . Test Next.js App Router routes, tRPC endpoints, and Cloudflare-native services — D1 (SQL) , R2 (object storage) , and KV — in local/edge-emulated conditions. Validate behavior differences between local dev, staging, and true edge runtime. 3. Manual & Exploratory Testing (Multi-Tenant SaaS) Manually validate complex user workflows and edge cases across a multi-tenant environment. Deeply test authentication flows ( Clerk or Better Auth ), including session edge cases, token expiry, and permission boundaries. Validate rate-limiting behavior (ArcJet) and confirm graceful degradation under throttling.



Verify multi-tenant account isolation — data, permissions, and billing boundaries between tenants must never leak. Cross-browser and responsive UI testing across real-world device/browser combinations. 4. API & Contract Testing Manually test APIs using Postman or Insomnia — auth flows, error handling, schema validation. Build automated contract/e2e test coverage using Playwright , Cypress , or Bruno . Validate data flow integrity through our end-to-end type-safe (tRPC) system, from client call to database write. Must-Have Skills Hands-on experience authoring and maintaining GitHub Actions workflows (not just "used CI/CD" — you've written the YAML yourself) Working knowledge of Wrangler and/or Miniflare for local edge simulation Automated testing experience in Playwright , Cypress , or Vitest API testing fluency: Postman/Insomnia (manual) at least one automated contract-testing tool Strong manual/exploratory testing methodology — not just scripted test-case execution Comfort with Next.js , Node.js , and modern JS/TS tooling Understanding of SaaS multi-tenancy concepts (tenant isolation, RBAC, subscription boundaries) Nice to Have Experience with tRPC (as a tester or developer) Familiarity with Clerk , Better Auth , or similar modern auth providers Exposure to ArcJet or other rate-limiting/bot-protection tooling Experience with D1 , R2 , or KV specifically ISTQB certification or equivalent formal QA training What We're Not Looking For Pure manual testers with no automation/CI exposure "Selenium Jenkins only" profiles with no exposure to contemporary JS-based test frameworks or GitHub-native CI/CD Candidates who list tools without project-level evidence of using them (we will ask for specifics) Email directly -
