Executive Assistant/Office Manager (part-time initially)

Part Time
San Antonio

Our San Antonio office is seeking to fill a new position for an experienced, senior-level administrative professional to be our Executive Assistant/Office Manager. This position may start out part-time with potential to grow very soon into a full-time position depending on the candidate and workload they may help build. While MIG’s offices are currently closed due to COVID and all staff are working remotely, this position will need to be in-person in the San Antonio office the majority of the week upon start date. Proof of up-to-date COVID vaccination is required.


Collaborative Teammate: You will work as part of a cross-office, cross-discipline team that creates designs and plans for communities of all size across the U.S., as well as higher education institutions and campuses and development projects for both public and private sector clients. 

Dual Roles: Your primary responsibility will be to provide executive assistance/project administration to our San Antonio, TX (and potentially our Sacramento, CA office’s Principals), which will be about 80% of your time. Your secondary (but equally important) role as the Office Manager will be about 20% of your time. Both of these roles require collaboration with local and firmwide leadership, other administrators, and our team of planners/designers to support their ability to focus on billable work, manage projects, and deliver high quality work products in a fast-paced environment.

Executive Assistant duties include but are not limited to: 

  • Supporting the Principal and future Director(s) in our San Antonio, Texas office with strategic and comprehensive calendar management for internal and external meetings; heavy travel arrangements; timesheets and expense reports; speaking engagement coordination; and other tasks related to the Principals’ multiple firmwide responsibilities. You will also help leverage the Principals’ time with prompt correspondence, meeting coordination, and project schedule management. Eventually, this position could evolve to full-time by supporting other Principals and leadership team members, likely remotely for our Sacramento office. 
  • Serving as an ambassador for the Principal(s) by providing a trusted contact for immediate follow up for colleagues, clients and prospective clients, other MIG offices, and partners.
  • Helping with client management by providing prompt, professional private and public sector client correspondence.
  • Assisting with various project-related tasks including invoicing calculations and coordination; expense reports; contracts procurement/coordination, project set-up and close-out; drafting additional services and scope changes; budget management; document layout, text flow, editing and proofreading.

Office Management duties include but are not limited to:

  • General office tasks - answering phones, receiving guests, supplies orders, mail distribution, facilities maintenance with leasing office, vendor coordination, and general assistance in keeping the work area tidy.
  • Project/accounting support – assist the Principals, accountants, and other office professionals with various project-related tasks. 
  • Internal reporting – complete various bi-weekly and monthly reporting duties for the office including financial health, sales, accounts receivable, and workload reporting.
  • Meetings coordination - for meetings with multiple attendees; conference room and virtual meeting room booking; meeting room set up/clean up.

This is a part-time, hourly position initially. Part-time employees are not eligible for MIG benefits, except sick time accrual, but this position may transition to full-time in the future. MIG works on projects nationwide; some travel, evening, and weekend work may be required to help our staff and to meet deadlines. MIG encourages a work-life balance, and these excess hours can be offset during the week when possible.




To accomplish these responsibilities, you will be able to manage competing priorities, think critically and creatively, work as part of a collaborative team in an open environment, and maintain a sense of humor and camaraderie. In addition, you will have some combination of the following qualifications: 

  • An Associate’s degree in any field. A Bachelor’s or Master’s degree in any field is a plus.
  • Relevant administrative office and executive assistance experience is required. Experience supporting projects in professional services consulting is preferred.
