Senior Executive Assistant

Executive Assistant

Circadia Health is a growth-stage healthcare AI company on a mission to prevent avoidable hospitalizations and transform senior-care operations. Our Circadia Intelligence Platform combines:

• Contactless sensing that monitors respiration and motion with medical-grade accuracy
• Native predictive models that detect 85% of preventable adverse events several days in advance
• Enterprise integrations that operationalize predictions directly inside EHR, care-coordination, billing, and compliance workflows

Today, our technology touches 40,000+ post-acute patients daily across skilled-nursing, home-health, and home-care networks. We are backed by leading healthcare and AI investors and headquartered in El Segundo, CA.

We are looking for a seasoned Executive Assistant to serve as a force multiplier across people, culture, and executive coordination. This is not a task-execution role — it is an ownership role. You will keep the company running smoothly, our people well-supported, and our leadership well-prepared, while also handling select personal and logistical matters for the CEO with discretion and care.

• 7+ years of experience as an Executive Assistant supporting C-level executives in complex, fast-moving environments.
• Proven ability to manage multi-faceted personal and professional needs simultaneously with composure and discretion.
• Experience working with entrepreneurial or self-directed executives — you know how to manage up, push back diplomatically, and anticipate needs.
• Startup or high-growth company experience a strong plus; entrepreneurial background welcome.
• Exceptional written communication — you write clearly, adapt to different voices, and know what level of detail each audience needs.
• Highly organized, systems-oriented, and proactive — you build structure rather than waiting to be told.
• Warm, personable, and culturally attuned — people enjoy working with you.
• Tech-savvy:
  Google Workspace, Slack, Notion, Docu Sign, and comfortable learning new tools quickly.
