Senior Test Automation Engineer

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. What Success Looks Like After 12 Months Critical Journey Protection: 100% of primary commerce flows are guarded by automated E2E tests in CI. Fast & Stable Pipelines: CI test suite execution completes in under 10 minutes with a test flakiness rate below 1%. Defect Shift: At least 80% of functional regression issues are caught in automated CI runs before reaching staging or production. Compounding Resilience: Every resolved high-priority incident has an associated regression test in the repository, making the harness the living memory of the platform. What We Are Looking For Experience: 5+ years of software testing and automation experience as an SDET or QA Automation Engineer working with modern web applications and distributed APIs. Practical AI Perspective: A sharp, realistic perspective on how AI tools impact modern software engineering—understanding why accelerated code generation elevates the need for deterministic test suites, strict interface contracts, and fast feedback loops. Core Tooling: Hands-on experience building robust, flake-free automated test suites in TypeScript / JavaScript using Playwright (or Cypress), alongside API testing frameworks. API & Contract Testing: Practical experience validating RESTful APIs, webhooks, and JSON data contracts across microservices. CI/CD Practicality: Working knowledge of GitHub Actions (or equivalent CI systems), with an emphasis on parallel test runners, containerized test execution, and pipeline debugging. Mindset: AI-first thinking, high autonomy and ownership, and office-first commitment in Rotterdam HQ. We encourage applications even if you do not meet 100% of the listed points. Relevant practical experience and problem-solving skills matter most. This role is not for you if you See QA as the step that happens after the "real" work; Want a fixed checklist and no ownership of strategy; Got into automation because it was on a job spec, not because manual repetition genuinely bothers you; Need heavy process to move; Would rather work from home than sit next to the team you are gatekeeping for. What we offer 🎯 Room to grow: opportunities develop fast, within your role and across HelloPrint 🌍 The team: 100+ people from 20+ nationalities who build at a pace most companies cannot match. Rotterdam is not a compromise. It is where the work happens. 🚀 Real impact: shape the future of a high-growth, AI-driven company where your ideas land in production the same week. 💡 Full autonomy from day one: no roadmap to follow, no brief to wait for. You see the problem, you build the solution, you own the outcome. 🏃🏻‍♂️‍➡️ Hello-Benefits: including 24/7 HelloFit gym access, UrbanSportsClub discount, the best events and company-sponsored healthy meals every day 💶 Base salary: 4500-6000 gross per month, depending on seniority and experience Ready to build something? We need bold thinkers, fast executors, and AI-first problem solvers. If that sounds like you, apply now. Let's redefine an industry together. At HelloPrint, we believe diversity makes us better. We're building a workplace where everyone can be themselves, grow, and do their best work regardless of background, identity, or perspective. We welcome applicants from all backgrounds.
