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 up-to-date 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 modern 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)
