At Q-tech, we’re partnering with a fast-growing international tech company that’s looking to hire a Senior Product Engineer to join their team. We’re seeking someone with a strong product mindset, a passion for technical excellence, and the drive to make a real impact through the development of digital solutions that improve people’s lives.

Their mission is to strengthen the relationship between people and their environment through technology, data, and user-centered design.
Your Mission
You’ll join a multidisciplinary team where your role goes far beyond writing code :
 * End-to-end product ownership : Take part in the entire product lifecycle — from technical definition to delivery — working closely with Product Managers, UX Designers, and Data Scientists.
 * Full-stack development : Design, build, and deploy scalable solutions across both frontend (web or mobile) and backend systems.
 * Technical excellence : Champion best engineering practices, including automated testing, solid database design, code reviews, and continuous deployment.
 * Mentorship & culture : Help the team grow by sharing your knowledge and fostering a culture of continuous learning.
 * User focus : Keep the user experience at the center of everything you build, creating intuitive, reliable, and impactful products.
What We’re Looking For
 * 5+ years of professional experience in software development (web or mobile).
 * Strong knowledge of relational databases and schema design.
 * Ability to quickly learn and adapt to new technologies.
 * Familiarity with agile methodologies (Scrum, Kanban, or similar).
Nice to Have
 * Experience with ReactJS / React Native on the frontend and Python (or another modern backend language).
 * Experience leading technical projects or collaborating in cross-functional teams.
 * Knowledge of CI / CD tools and automated deployment.
What’s on Offer
 * Permanent contract and competitive compensation package.
 * Performance-based incentive plan.
 * Private health insurance and pension plan.
 * Meal vouchers (Cobee).
 * Flexible working model and a pet-friendly office environment.
 * Office located in Barcelona, with partial on-site attendance.
 * Relocation support for candidates moving from outside Spain.
If this sounds like the right challenge for you, Q-tech will guide you throughout the entire selection process — from the first conversation all the way to your onboarding.
