We work in an open floor plan, so there is a lot of opportunity for networking across roles, teams and levels. Everyone is very friendly and welcomes the opportunity to get to know other people on the floor.

Kristina

Digital Adoption Team Lead

What's the biggest problem your team is solving?

You don’t think of insurance as a hotbed for innovation but the very nature of our organization, Digital Experience, is to reimagine how a 168-year old company does business with its customers. Our Design team takes pride in an inclusive design process with everyone invited to provide feedback, from Product to Engineering to QA.

Maria

Digital Lead - Design

What makes someone successful on your team?

Successful people on my team are: passionate, curious, receptive, and engaged. Each team member is expected to be passionate about the work that they do, and the domains in which they practice. They are always solving unique problems and must be curious about finding new solutions.

David

Digital Lead

How do you empower your team to be more creative?

I encourage my team to embark on ‘deep work’ at least once a week on a ‘meeting-free’ designated day. We have design reviews to brainstorm alternative ways to solve business problems from a software engineering point of view. We consider self-reflection and brainstorming to be fundamental components of creativity.

Mike

Head of Data Science Software Engineering

How do your team's ideas influence the company's direction?

One of our projects is an application we built for our Investment Mgmt team called ViPER (Visualizing Investment Portfolio Enhanced Reporting). The application makes it easy to manage reports and get insights from Data Science models. Now with ~150 active users, it reflects how we’re using DS to facilitate data driven decision processes across MM.
