An Insider's view of DFIN

What’s the vibe like in the office?

I am working among an extremely smart group of people, of which I have created great friendships with. During lunch break we play board games and have interesting technical and financial discussions. It’s exciting to wake up and go to work knowing that I’ll be collaborating with some of the best colleagues I’ve had in my career.


Software Engineer

What projects are you most excited about?

In transforming and improving FinTech products, excitement comes from the challenge of knowing that the problems are complex, yet the solutions must be easy to use. When we start a new project, I can't wait to sink my teeth into understanding the problem space, talking to users, designing the solution, and seeing it through to release.


Principal Product Designer

What makes someone successful on your team?

A successful member of our team at DFIN is comfortable to work with or learn any part of the tech stack. They effectively communicate during meetings to help plan out our next projects as a team, and they ask other members of the team for support if they happen to get stuck while coding.
