About Endevica Bio

Endevica Bio is a clinical-stage biotechnology company north of Chicago. We design novel peptide-based medicines for complex diseases where patients still have too few good options. Our team brings together people with different strengths and a shared commitment to getting meaningful work done, with each person playing a direct role in moving the company forward. There is ambitious science happening here, and there is a real sense that the work we do today could meaningfully change patients’ lives tomorrow.

We’re a very small company. This is intentional. A lean team keeps us creative, collaborative, and closely connected to the work. Everyone knows what the company is working toward, everyone has a voice, and no one is limited to a narrow corner of the job description. Work moves quickly, priorities evolve, and people who bring good judgment, initiative, and follow-through can make an immediate difference. If you’re resourceful, open-minded, and enjoy helping a busy team get things done, you’ll find plenty of opportunities to make a difference here.

About the Role

We are seeking a Senior Executive Assistant to provide high-level support to our CEO and coordinate activities across the executive team. In this role, you will bring structure to busy schedules, anticipate needs, manage competing priorities, and take ownership of projects from initial planning through completion—all while keeping pace with a small biotech where the science moves quickly, plans evolve, and the occasional curveball is part of the day.

This position calls for an experienced executive assistant who is comfortable working independently, exercising discretion, and keeping work moving in a fast-paced, energetic environment. You will manage complex calendars and travel, coordinate conferences and executive meetings, and ensure that decisions translate into completed actions. You will also work closely with our office manager, collaborating on priorities, coordinating shared responsibilities, and supporting timely project completion.

Key Responsibilities

• Manage complex calendars, resolve scheduling conflicts, and coordinate communications with executives, board members, and external partners.
• Own administrative and executive projects from planning through completion, coordinating contributors, tracking deadlines, and following through on commitments.
• Organize board and leadership meetings, including scheduling, agendas, materials, logistics, and confidential document distribution.
• Capture meeting decisions and action items, coordinate follow-up, and bring unresolved issues forward promptly.
• Coordinate business travel and conference logistics, including registration, transportation, accommodations, itineraries, and meeting schedules.
• Prepare correspondence, presentations, and briefing materials, and reconcile expense reports and related documentation.
• Collaborate with the office manager to prioritize workloads, delegate and coordinate tasks, establish clear ownership, and bring shared projects to completion.
• Improve administrative processes, maintain organized records, and coordinate coverage to ensure consistent executive support.
• Provide limited personal administrative support to the CEO while handling all sensitive business and personal information with discretion.

Qualifications

• 10+ years of progressively responsible executive support experience, including substantial experience supporting a CEO or other senior executives.
• Prior experience managing or supervising administrative staff, with demonstrated ability to delegate, coordinate priorities, and work collaboratively.
• Demonstrated success in a fast-paced, energetic environment with shifting priorities and a high degree of individual accountability.
• Strong project management skills, with a track record of independently moving projects from planning through completion.
• Experience managing complex calendars, business travel, conference logistics, and executive meetings.
• Excellent organizational skills and attention to detail, with reliable follow-through on both immediate requests and longer-term commitments.
• Sound judgment, discretion, and confidence handling confidential information and interacting with executives, board members, and external pa
