• Contribute to evidence-generation activities, including Investigator-Initiated Studies (IIS), research collaborations and real-world evidence initiatives.
• Support the development and execution of Medical Affairs plans in close partnership with internal and external stakeholders.
• Develop and support congress strategies, scientific communications, medical education initiatives and scientific exchange.
• Explore the use of real-world evidence, data analytics and AI-enabled approaches to strengthen Medical Affairs insights and decision-making.
• Collaborate closely with colleagues across Commercial, Market Access, Regulatory and Clinical Development to support aligned, patient-centric medical strategies.

Success in this role means turning scientific insights into strategic action, influencing medical and organizational decisions, building trusted external partnerships, and helping to close evidence and care gaps through science and innovation.

Your Qualifications

To be successful in this role, you bring:

• An MD, PhD, PharmD or equivalent advanced scientific qualification.
• 3–5+ years of relevant experience within Medical Affairs, Medical Science Liaison, Clinical Research or a related pharmaceutical industry role.
• Previous experience within nephrology, cardio-renal diseases, coagulation, iron, rare diseases or specialty care.
• Experience supporting scientific exchange, evidence generation, Investigator-Initiated Studies and medical education initiatives.
• Demonstrated ability to collaborate effectively with cross-functional partners, including Commercial, Market Access, Regulatory and Clinical Development.
• Familiarity with the Spanish healthcare environment.
• Excellent communication, scientific exchange and stakeholder engagement skills.
• A strategic mindset with the ability to translate complex scientific information and stakeholder insights into meaningful actions.
• Fluency in Spanish and English.

• The opportunity to contribute to Medical Affairs strategies that can make a tangible difference for patients.
• A highly scientific role combining external engagement, evidence generation and strategic Medical Affairs work.
• The opportunity to collaborate with leading scientific experts and multidisciplinary teams in an international environment.
