IONOS is forming an engineering unit dedicated to the strategic modernization of the

Nextcloud Office

ecosystem. Our mission is to transform the existing Only Office core into a high-performance, real-time collaborative suite that sets new industry standards for speed and responsiveness.
We operate as a high-velocity lab, solving deep architectural challenges at the intersection of legacy systems and modern web technologies.

We don’t just maintain software; we re-engineer it for the future.

This team offers the stability of an industry leader with the agility of a tech startup.
The Role: The Testing Force Multiplier

As our SDET & AI Automation Specialist, you are the force multiplier for our quality control. Your goal is to manage an automation "strike force" that would traditionally require a team of five, utilizing

a limitless AI budget

and cutting‑edge tools.
Key Responsibilities

Automated Suite Generation : Use AI to rapidly "prompt" end-to-end (E2E) test cases into existence.



You won't write selectors manually; you will orchestrate AI to analyze the UI and generate robust, self‑healing tests.
Bot Swarm Orchestration : Maintain and run "Headless Bot" clusters that simulate complex user behavior (multi‑user typing, heavy spreadsheet calculations) to stress‑tset the synchronization logic.
Intelligent Regression Maintenance : Leverage AI to automatically update test suites when the UI/UX changes, ensuring our "Green Build" status is never compromised by brittle tests.
Continuous Monitoring: Analyze test logs and performance traces using LLMs to identify the "Root Cause" of failures across the JS/C++ bridge.
Technical Profile

We are looking for someone who wants to build:
Master Prompter : Expert at using AI to generate code, mocks, and synthetic test data.
Infrastructure : Comfortable with Docker and CI/CD environments to manage large‑scale test execution.
