Clinical Research Intern (Fixed-Term contract)

Natural Cycles° is a leading women’s health company that developed the world’s first birth control app, used by millions globally. We are a fast growing startup, and we promote an international working environment filled with smart and ambitious colleagues based in Stockholm, Geneva, New York, and remotely. Our mission is to pioneer women’s health through research and passion, empowering every woman with the knowledge she needs to take charge of her health.

As a Clinical Research Intern, you will support the trials management team across a range of tasks while serving as a point of contact for research participants. Day-to-day, this includes monitoring data collection, troubleshooting, managing inventory, and assisting with logistics — all while helping look after participant well-being and engagement. You will work closely with the MAD (Medical Algorithm and Data) team and collaborate cross-functionally with Finance, IT, and HR. The role is primarily local, supporting a Stockholm-based team. As most participant communication — both verbal and written — takes place in the Stockholm area, proficiency in Swedish is a plus. Strong English skills, both spoken and written, are essential. Given the nature of clinical trials, workload can vary, and we are looking for someone who is comfortable working flexible hours.

Please note that we are hiring for this role in Stockholm, Sweden. This is a fixed-term position with an expected end date of December 2026.
