NICE TO HAVE * Experience working in healthcare, digital health, medical software, or other regulated environments. * Previous experience with patient data, identity management, or clinical workflows. * Knowledge of Spring Boot, Java, Maven, or Java backend ecosystems. * Experience with Playwright. * Experience replacing or modernising existing automation frameworks. * Experience with contract testing, distributed systems, or end-to-end integration testing. * Experience with Docker and containerised development or testing environments. 💜 WHY YOU’LL LOVE WORKING AT NUVOLAR * Flexible Work & Work-Life Balance: enjoy options to balance work and personal life, including every other Friday off. * Remote Work: this is a fully remote position, giving you the flexibility to work from anywhere in Spain while staying closely connected with your team. * Seniority Program: enjoy additional benefits and privileges as you grow with the company. * Social & Team Budget: even though we primarily work remotely, we encourage team gatherings and activities, with a dedicated budget. * Continuous Learning: access training, mentorship, and professional development opportunities. * Growth Opportunities: participate in challenging healthcare technology projects, work with modern technologies, shape the QA strategy of a growing product team, and contribute to the evolution of quality engineering practices. 👥 THE HIRING PROCESS 1.
