Overview

Circadia Health is a rapidly scaling, Series B healthcare AI company transforming senior care through predictive analytics and agentic AI workflows across 300+ skilled nursing facilities and expanding into home health and hospice.

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.

The right candidate brings deep experience supporting complex executives and high-growth organizations, a natural instinct for anticipating needs before they arise, and the entrepreneurial mindset to build systems and processes where none yet exist.

Core Responsibilities

    • Serve as a strategic extension of the CEO — owning scheduling, travel, and communications with precision and foresight.
    • Manage complex executive calendars, proactively protecting time for high-priority work and ensuring readiness ahead of key meetings.
    • Coordinate domestic and international travel with seamless, end-to-end itineraries.
    • Draft, edit, and manage high-stakes correspondence on behalf of the CEO, adapting voice and detail level to the audience.
    • Manage NDAs and DocuSign agreements coordination end-to-end.
    • Prepare materials, briefing notes, and agendas for board meetings and leadership reviews.
    • Track and organize sales pipeline activity and follow-through to ensure nothing falls through the cracks.
    • Welcome and host interview candidates on-site, creating a strong first impression of Circadia.
    • Own the office environment — ensuring it is welcoming, stocked, and operationally smooth at all times.
    • Plan and execute team socials, off-site events, and culture-building moments.
    • Manage company swag program from selection to distribution.
    • Coordinate team catering, including lunch 3x per week and the sandwich bar.
    • Handle select personal tasks for the CEO with discretion, reliability, and no friction.
    • Manage time-sensitive personal logistics proactively, anticipating needs before they become urgent.

Ideal Profile

    • 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, DocuSign, and comfortable learning new tools quickly.
