An Insider's view of Postmates Inc.

What's something quirky about your company?

One thing that makes me proud to be a part of Postmates, is our program FoodFight. It is a Postmates driven partnership with local shelters that makes sure leftover food from restaurants makes its way to a shelter and feeds those who are hungry. We care immensely about the communities that we serve, and FoodFight is one way that we show it!

What's the biggest problem your team is solving?

Our Security team ensures our users, merchants, and Postmates info is safe. We develop and deploy mitigations to eliminate the potential for vulnerabilities that pose a security risk. Driving these projects from start to finish and seeing the impact of our work is extremely rewarding.

How does the company support your career growth?

I once read that “growth and comfort don’t coexist” and Postmates lives by it. From day one at Postmates, I felt challenged and have been given projects that impact the business. I’ve had to flex technical muscles that I have never used and it’s exciting because I’m developing into a more well-rounded engineer which only enhances my career growth.

How do you empower your team to be more creative?

Instead of assigning work/tasks to my team, we operate by having the team identify what they think are the problems that we need to be solving today, and how that will scale or change over the next few years then align those with company priorities. This forces my team to be more creative in how they approach their work on a day to day basis.

What are some social events your company does?

Postmates is a fun place to work. We hold various social events throughout the year, both locally in Bellevue and at the San Francisco HQ. Last year, we held a team event at Golden Gate Park, movie nights and happy hours in SF, as well as a hike and Christmas party in Bellevue. Looking forward to more fun events this year!
