Position Summary

Soufflé Therapeutics is seeking an experienced, highly organized, and proactive Team Assistant to serve as the scheduling and coordination backbone for our 8-person Executive Leadership Team (ELT). This is a senior individual contributor role that demands someone who has excelled in fast-paced, high-stakes environments — ideally at a growth-stage and who understands the urgency, discretion, and adaptability that a leadership team at this stage requires.

This role is purpose-built around group and external scheduling, ensuring the internal and external meetings as well as company events are coordinated and well executed. The Senior Administrative Assistant owns multi-party internal meetings, board and investor coordination, external stakeholder scheduling, and travel logistics. At a company of our size and pace, this person will have real impact and high visibility from day one.

This role is right for someone who finds deep satisfaction in flawless coordination at scale — and who wants to be the operational heartbeat of a leadership team on the verge of something significant.

Key Responsibilities

Internal Meeting Coordination

• Own end-to-end scheduling for all ELT and related group meetings, including standing syncs, All-Hands, strategy sessions, offsites, and cross-functional working groups
• Navigate complex, multi-stakeholder calendars with confidence — identifying availability, proactively resolving conflicts, and optimizing meeting cadences across a fast-moving ~100-person organization
• Manage all meeting logistics: room booking, video conferencing setup (Zoom, Teams).
• Maintain a master leadership calendar and proactively surface conflicts, scheduling risks, or gaps before they become problems
• Act as a reliable coordination hub, partnering with department leads to keep the leadership team aligned, informed, and on schedule

External & Board Scheduling

• Lead scheduling with high-profile external parties including Board members, investors, strategic partners, collaborators, and key opinion leaders — a critical responsibility at this stage of the company

Travel Coordination

• Coordinate leadership travel — individual and group — through the company’s third-party travel agency, including flights, hotels, ground transportation, and detailed itineraries
• Align travel logistics tightly with meeting schedules and ensure all travelers are prepared and informed well in advance
• Manage real-time changes, cancellations, and contingencies with composure and efficiency

Tools, Process & Operational Excellence

• Serve as the internal expert for scheduling tools and automation, including Microsoft Outlook, scheduling bots, and emerging platforms — driving adoption and continuous improvement across the team
• Build and maintain scheduling processes, templates, and playbooks that will scale with the company into the next phase
• Onboard new team members to scheduling norms, tools, and best practices as the organization grows
• Spot operational inefficiencies and proactively propose solutions that protect leadership’s most valuable resource: their time

Qualifications

• 6–10 years of experience in an administrative, scheduling, or operations coordination role supporting senior leadership in a fast-paced environment
• Prior experience at a growth-stage startup, or similarly high-velocity organization strongly preferred
• Expert-level proficiency in Microsoft Outlook calendar management, including shared calendars, delegation, resource scheduling, and complex multi-party coordination
• Proven track record communicating directly and professionally with board members, investors, or equivalent senior external stakeholders
• Hands-on experience with scheduling automation tools (e.g., Calendly, Microsoft Scheduler, or similar bots)
• Experience managing corporate travel logistics through a third-party travel agency
• Exceptional judgment, discretion, and composure — especially comfortable in confidential, high-stakes, rapidly evolving environments
• Strong written communication skills; polished and professional in all external correspondence
• Bachelor’s degree preferred, or equivalent experience
