Insider's spotlight

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

Groupon provides an environment where I can strive for maximum work-life effectiveness, room for growth, and there is always something new to do. I enjoy spending lots of time at work because I love what I do; the hours are not burdensome, Groupon fits me. I define success in my own terms & Groupon provides us with the flexibility to be successful.

Milan

Senior Manager of Operations

What kinds of technical challenges do you and your team face?

We are working on arriving at the optimal attribution models across different areas of our business. For example, the attribution of a purchase to a specific experience — a home page feature, an email, a push notification — likely has a different window of time where we can reasonably say a specific purchase is a result of a specific experience.

Kristi

Data Scientist

How has your career grown since starting at the company?

Here at Groupon, what you do matters. I got my start at Groupon as an intern and have had the opportunity in the past (almost) 5 years to build out a global volunteer program that has engaged over 5,000 employees in over 63,000 hours of service supporting the work of close to 650 nonprofit organizations.

What projects are you most excited about?

Recently, we committed to having 100% of our job descriptions reviewed for gender balance by the end of 2018. Also for 2018, work will continue with our Employee Resource Groups, who play a pivotal part in the attraction and selection of diverse top talent, and themselves can be developed and promoted into company leaders.
