Executive Assistant to CEO & Office Manager

San Francisco, CA

The Role

We're looking for an experienced executive assistant to partner with and support the CEO, Keith. In this role, you will work directly with Keith, juggling and executing a range of administrative duties including calendar management, internal and external communication on his behalf, travel, and meeting preparations. You'll become a trusted partner to anticipate needs and partner closely with other executives (internally and externally). 

In addition to being a key partner to the CEO, you’ll play a critical role in helping create a dynamic and welcoming office experience through vendor coordination, event planning, and a variety of special projects (i.e., figuring out how to incorporate more Mystery into our office experience).

About You

We’re looking for someone who combines three key traits: excellent project management skills with a high attention to detail; a natural energy for bringing people together and ensures that everyone has a great time; and a strong understanding of systems and processes. 

Day to Day

In this role, you'll be juggling multiple priorities simultaneously so the ideal person is someone that has the ability to exercise good judgment in a variety of situations and is hyper organized. There are two areas that you’ll be focused on in this role. 

The first is to ensure Keith spends time on the most important priorities. This will involve tracking all the happenings in the company in conjunction with his to-do list to constantly refresh priorities, doing a daily sync with him and weekly calendar audits to cut scope or take projects off his plate, and putting operational procedures in place to make repeating items more efficient (such as weekly meetings). 

This also means learning as much about the business and current priorities as you can so that you can serve as a proxy whenever possible. You might spend a part of your day checking the status of a project, connecting with a manager to get a sense of the scope and importance of a meeting before scheduling it, and drafting important business correspondence such as investor updates.

The second area will be a range of special projects to support the team and make sure we create a great office experience. For the most part, this runs pretty smoothly on its own. But here are some things this role may include: coordinating with our catering service for our team lunches, being the point of contact for a number of vendors (facilities, IT, etc.), figuring out how to set up a custom jellyfish tank in our office, and planning in-office team events. You’ll be a critical part of helping Mystery run smoothly by coordinating across every team. 

In this role you’ll report to our Director of People Operations, Michelle. We are headquartered in San Francisco and this position is based in our office.

Package & Perks

If you’re looking for the basics:

  • $4M in funding from leading education investors (and we’re already profitable)

  • Competitive salary

  • Equity in a high-growth company

  • 401K, health care, vacation

  • Customers who love us

…but the real perks of working at Mystery.org are the quality of the people on your team and the problem we’re solving. Those things are what bring us to work every day.

About Mystery.org

We started Mystery.org to create better explanations for every question children have about the world. We began with the 150 most common science questions that children ask teachers. We call this collection Mystery Science. Last year, more than 4 million children used Mystery Science in 50% of U.S. elementary schools. In an industry that is plagued by long sales cycle and high barriers to entry, we’ve sold thousands schools without a single sales person. We’re backed by a great group of investors including Y Combinator, Learn Capital, and Reach Capital.

We’re now moving on to all the other questions children have that they’ll never learn in school. In the last 18 months we received over 500,000 questions from children eager for better explanations of the world.  Now we’re creating video explanations for every question. You can think of this like a visual Wikipedia for kids.

Our goal is to create a generation of better thinkers. We think this is the most important problem to solve in the world today.

Meet The Team

On your first day at Mystery.org, you’ll meet a team of people who are passionate about science and teaching, and who each love their respective crafts. Our co-founder, Doug Peltz, began by assembling the best science explainers in the world from the Exploratorium, Klutz, LePort Schools, Stanford, and The Field Museum. Our focus on people extends to every area of the company. We’re building the team that we want to work with.

We are a product-driven company. The core of what we do is create an incredible product that our customers love. We test every science activity, observe every explanation with children, and talk with teachers constantly. We take our responsibility to envision the future of learning very seriously and we want to bring the best science education to every child in the world. This is an opportunity to join a startup and transform science education for the next generation of children.
