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

- 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.

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.

- 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.

- 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-protected (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 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)
