## Job description

HelloPrint is on a mission to become the world's leading infrastructure for customizable printed products. From our offices in Rotterdam and Valencia, 100+ professionals from 20+ nationalities are building an AI-first company that scales output faster than headcount. We are rebuilding the platform: ecommerce, APIs, internal tooling, all under active development at speed. Speed without quality is just faster breakage. This role exists to make fast releases safe, and to turn QA from a bottleneck into leverage.

### About the Role

At HelloPrint, our engineering teams are accelerating development cycles using autonomous and AI-assisted tooling. While AI makes generating code exponentially faster and cheaper, verifying that core business workflows and transaction guarantees remain intact stays just as complex. Without a rock-solid testing harness, higher code velocity simply translates to higher operational risk.

We are looking for a Senior Test Automation Engineer to take technical ownership of our automated Platform Test Harness. In this role, you will design, build, and maintain the end-to-end and contract-testing architecture that enables our teams to develop with AI fearlessly, safeguarding our core customer and commerce flows under continuous delivery.

### What You Will Do

- Architect the Platform Test Harness for AI Velocity: Design, implement, and maintain deterministic E2E test suites using Playwright and TypeScript. Build the automated guardrails required to safely absorb high-frequency, AI-assisted code generation without regression.

- Implement Contract Testing & Boundary Validation: Establish strict API schema validations and contract tests (REST / JSON Schema) at service boundaries to prevent schema drift between our Product Catalog Engine, checkout services, and partner integrations.

- Shift-Left Quality in AI Workflows: Partner with Product Owners and software engineers during sprint refinement to define explicit boundary contracts and edge cases upfront—embedding a clear Definition of Done before feature code or AI prompts are executed.

- High-Speed CI/CD Orchestration: Maintain and optimize GitHub Actions test pipelines, focusing on smart test parallelization, artifact caching, and keeping feedback loops under 10 minutes.

- Accumulate Platform Memory: Partner with engineering during post-incident reviews to ensure every confirmed production defect results in an automated test that makes that specific failure path impossible to repeat silently.

- Collaborate & Mentor: Pair with our QA Automation Engineer and mentor software engineers in writing effective integration tests, adopting TDD habits, and reviewing AI-generated test scaffolding.

**Live in the employer’s hiring system.** Read from the company's own applicant tracking system, not reposted from a job board — so it's a real, open requisition rather than an ad that outlived the role.

We remove it as soon as it disappears at source.
