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 setting 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 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) Email directly -
