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 workplace 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 Tes
