Executive Assistant

Join us in changing the world (for real).

This role is for someone who means it when they say they want to make an impact.

If you’re an exceptional administrative professional who takes pride in being the person who makes everything work better -- someone who thrives in fast-moving environments, loves solving problems, and sees administrative excellence as a craft -- we’d love to meet you. At Rule4, administrative support isn’t an afterthought. It’s a force multiplier. You’ll be a trusted operational partner to our leadership team and a steady presence in our Boulder office, helping an ambitious, mission-driven organization do its best work.

This is not a clock-watching, “do the minimum” role. Some weeks are calm; others require extra energy, judgment, and follow-through. You’ll have autonomy, trust, and meaningful responsibility. But you’ll also be expected to show up fully when it counts. If you’re energized by variety, ownership, and seeing things through because they matter, you’ll thrive here.

This role is fully on-site in our Boulder, Colorado office and is not eligible for remote work.

You’ll provide high-level administrative and operational support to our executives while also ensuring our Boulder office runs smoothly and professionally. You’ll work side by side with a smart, kind, hard-working team supporting clients who are changing the world across healthcare, private equity, manufacturing, utilities, government, outdoor recreation, and more.

Core responsibilities include:

• Serve as a trusted operational partner to the Co-CEOs and senior leaders—anticipating needs, removing friction, and enabling leaders to focus on high-impact work
• Manage administrative projects requiring confidentiality, discretion, independent judgment, and critical thinking
• Own day-to-day office operations, including beverages, snacks, supplies, and overall office readiness
• Manage complex vendor relationships and coordinate facility repairs, maintenance, and improvements
• Provide on-site support for community and company events, including setup and catering (early evening events ~3–4x/month)
• Perform minor accounting and expense-related tasks
• Assist with presentation preparation, document formatting, and light design or layout work
• Run errands and occasionally visit clients (primarily in the Boulder/Denver area)
• Step into new or unfamiliar tasks with confidence and curiosity—you won’t be doing the same thing every day

You’re not just completing tasks; you’re improving how things work. You’ll be successful if you:

• Take pride in being the person others rely on
• Notice details others miss and fix problems before they become problems
• Balance urgency with thoughtfulness in a fast-paced environment
• Use technology to think, organize, and communicate clearly
• Care deeply about quality, professionalism, and follow-through
• This is not a stepping stone out of administrative work—it’s a role for someone who wants to master it

• A perfectionist’s eye for detail and a professional’s sense of priorities
• Comfort adapting to rapidly shifting needs and frequent context switching
• A growth mindset, resilience, and the ability to learn from feedback quickly
• Strong written and verbal communication skills with staff, executives, board members, clients, vendors, and partners
• Collaborative instincts, emotional intelligence, and a sense of humor
• The ability to take feedback professionally—and use it to get better
• Deep comfort using technology to work smarter (advanced document formatting, presentation creation, learning new tools independently)
• Strong skills in Microsoft Word, Google Docs, and PowerPoint (track changes, styles, templates, formatting)
• Experience using instant messaging tools like Slack or Teams as a primary communication channel
• Confidence multitasking and re-prioritizing in real time
• A genuine love for variety and doing something different every day
• A valid driver’s license, reliable vehicle, and current insurance

• Extremely fast-paced
• Highly varied. No two days look the same
• An individual contributor role with real autonomy
• Heavy on judgment,…
