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.

Paul

Associate 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.

Matt

VP, Product Management:

How would you describe the company’s work-life balance?

Conversant has a very good work-life balance, including unlimited PTO. As a young adult, traveling around the world is one my top priorities and working with a company that aligns with that is a huge plus. I have had the flexibility to visit 7 countries. That flexibility is one of many things that has kept me at Conversant for five years.
