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 Assistant, you will be the main point of contact for research participants.

You will be part of the MAD (Medical Algorithm and Data) team and collaborate with several other teams, including the Regulatory Team, Product Team, UX Team, Logistics Team, Finance Team and People Team. This role involves supporting a global team and engaging with participants across different time zones, and therefore, we are looking for someone who can work flexible hours when needed. This may include occasional communication with contacts in regions such as the United States, outside of standard Swedish working hours. Your primary focus will be communicating (both verbally and in writing) with participants in the US territory, so excellent English communication skills are essential.

• Manage trial daily operations: address participants' questions and issues, schedule additional meetings when necessary, send out follow-up emails and surveys.

• Assist with the preparation, review, and distribution of all operational trial-related documents (e.g., study consent, guides, etc.).

• Assist and monitor the recruitment of the trial participants; monitor the collection of signed documentation.

• Assist with setting up systems for filing: prepare documentation to safely store participants' information and data.

• Assist with the onboarding of the trial participants: for in-person onboarding, schedule sessions with each participant and prepare relevant documentation; for remote onboarding, schedule sessions and shipment of trial material if applicable.

• Assist with the offboarding of the trial participants: collect relevant feedback from the participants, gather the study material when applicable, and coordinate with the Finance team to ensure the compensation is granted.

• Assist with study supplies and inventory management.

• Contribute to the optimization of processes related to clinical trials.
