We are looking for an Specialist QA Automation Engineer for the Euro Office Performance Group (Server Development) team: 

What we'd like to see

• Automated Suite Generation: Use AI to rapidly "prompt" end-to-end (E2E) test cases into existence. You don't write selectors manually; you use 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-test the sync logic.
• Regression Maintenance: Use AI to automatically update test suites when the UX/UI Modernizers change the interface, ensuring our "Green Build" status is never lost to brittle tests.
• Continuous Monitoring: Analyze test logs and performance traces using LLMs to identify the "Root Cause" of failures across the JS/C++ bridge.

Expectations

• Being part of a multidisciplinary team passionate about technology, with an open and dynamic culture, where experimentation and discussion are encouraged to progress at work, always with respect and inclusion.
• We offer personalised career plans, annual performance evaluations and programmes to develop skills.
• We operate in Spanish and English and therefore provide unlimited language training. We work on international projects and define best practices with United Internet partners.
• We have flexible start and finish times, respecting a schedule of meetings in the central part of the morning and a range of work from 7 a.m. to 9 p.m. with a hybrid model in one of our offices (Alcobendas, Barcelona or Logroño).

At Arsys we value diversity and welcome all applications regardless of, for example, gender, nationality, ethnic or social origin, religion, disability, age, as well as sexual orientation and identity, physical characteristics, marital status or any other irrelevant factor subject to applicable law.
