• 5+ years of experience supporting a CEO, Founder, Executive, or senior leadership team in a fast-paced environment; experience in a startup, high-growth company, private equity, consulting, investment, professional services, or similarly demanding environment is highly valued.
• Exceptional organizational and time-management skills with the ability to manage multiple priorities simultaneously while maintaining accuracy and attention to detail.
• Strong project management skills with a demonstrated ability to take ownership of initiatives, coordinate stakeholders, track deliverables, and follow projects through completion.
• Highly proactive and resourceful, with the ability to anticipate needs, work independently, make sound judgment calls, and naturally ask, “What else can I do?”
• Excellent written and verbal communication skills with the ability to interact confidently and professionally with executives, investors, clients, employees, and external partners.
• Strong business acumen, genuine curiosity about how businesses operate, and the ability to understand the bigger picture while remaining extremely detail-oriented.
