Office Manager Opening

PDF of Office Manager Job Description 

We are on the hunt for an Office Manager to help aid in the success of ESC’s mission and streamline our day-to-day office logistics. This position will report directly to the ESC’s Executive Director and be responsible for a variety of office functions, from bookkeeping to organizing logistics for our annual fundraising event.


Our team is small but mighty at the Environmental Science Center. We are a non-profit whose mission is to promote environmental stewardship and academic achievement through science-based education.  We are dedicated to fostering a passion for the environment in our diverse community by getting people outside and using nature as our teacher. ESC prioritizes working with groups who historically have had less access to environmental science opportunities.  We deliver hands-on programs at local beaches, forests, rivers and classrooms. Our programs increase science literacy, provide an opportunity for more diversity in STEM career fields, and increase healthy every day choices that affect the Puget Sound ecosystem and our community. We have a strong belief in our mission and are driven by the work we get to do.

You thrive working in a non-profit, with a small team, and want to stay planted for the long term. Working with a team of dedicated environmental stewards in a grass roots atmosphere is your dream job.
