Committed to the Best

Why work for MacDonald-Miller? At MacMiller, it’s personal. We take our work seriously, and we seriously enjoy working with each other.

We put our employees first because we know they are the company. We appreciate the time, energy, skills, ingenuity, and dedication of every single one of our employees. We have loved showing our gratitude throughout the years with our Annual Macfest Employee Appreciation Party, Monthly Mac90 Events and Games, BBQs, Softball Teams, Onsite Ping-Pong Tournaments, Health and Wellness Challenges, Aloha Shirt Fridays, and more.

As companies have had to adapt to the new normal, like working remotely, we’re fortunate MacMiller Leadership invested in technology and innovation over the years. (We’re no stranger to Virtual Reality – check out our MLab!) As a result, we have been able to leverage opportunities to connect with all 1200+ employees with regular virtual events like town halls, road shows, and team building events.

What does a MacMillian look like? We look for a person who values our core values – collaboration, community, dedication, innovation, safety, and fun!

How do we create this company culture? We are not a company of lone rangers. We are a team that wants to work together, sharing knowledge and expertise across departments, to help arrive at one common goal – to be the best in the Pacific Northwest no matter what challenges come our way.
