An Insider's view of Epsilon

What's something quirky about your company?

We have a company band, made up of anywhere from 30 to 40 employees at a given time. The band has a large following and performs at charity events around Chicago. They also perform a full set at Epsilon’s holiday party each year at the House of Blues. My jaw hit the floor when I saw my peers up on stage rocking out.

Senior Automation & Infrastructure Engineer

How do you collaborate with other teams in the company?

We collaborate through storytelling. It’s not ‘how’ we build it, but rather ‘why’ we build it. We need to tell stakeholders a story about a consumer pain point, solving it in a differentiated manner and the larger vision. Then, collaboration occurs as we incorporate feedback and have a motivated team building towards a shared vision.
