Participant Coordinator (Contractor)

Cambridge, MA USA

FL127 is a privately held, early-stage company operating within the Flagship Pioneering ecosystem. The company is developing a first-in-category platform anchored in novel device technology, with the potential to transform how human wellness is understood and managed. FL127 is currently building its scientific and technical foundation through a rigorous, hypothesis-driven experimental program. We are assembling a lean, high-impact team of scientists and engineers who thrive at the intersection of hardware, software, and biology, and who are excited to build in an era when AI agents are first-class members of every team.

The Role

We're looking for a detail-oriented Participant Coordinator to manage the logistics of bringing study participants on site. Our researcher conducts all hands-on experimentation; this role keeps the participant pipeline moving behind the scenes identifying candidates, reaching out, and scheduling their visits. It is a part-time, fully remote contractor position of roughly 10 hours per week, with no in-person presence required.

What You'll Do

• Review and search a participant database to identify candidates who meet study eligibility criteria.
• Reach out to prospective participants by email, phone, or text to gauge interest and confirm fit.
• Schedule and coordinate on-site visits, aligning participant availability with the research calendar.
• Send reminders, confirmations, and any pre-visit instructions to keep no-shows low.
• Track participant status, communications, and scheduling in a shared system, and keep records accurate and up to date.
• Serve as the friendly point of contact for participant questions leading up to their visit.
• Flag scheduling gaps or recruitment shortfalls early so the team can adjust.

What We're Looking For

• Strong organizational skills and reliable follow-through on administrative tasks with minimal oversight.
• Clear, warm, and professional written and verbal communication you'll be the first impression for many participants.
• Comfort working with databases, spreadsheets, scheduling tools, and email.
• Discretion and care in handling sensitive personal and health-related information.
• Ability to work independently and manage your own time within a ~10 hour/week commitment.

Nice to Have

• Prior experience in clinical research coordination, participant recruitment, or a study/lab setting.
• Familiarity with human-subjects research practices or IRB processes.
