An Insider's view of DFIN

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.

Dan

Principal Product Designer

What makes someone successful on your team?

Active and honest listening – Contrary to the stereotypical, extroverted sales rep, some of my most effective and insightful client interactions are when I do the least amount of talking, and the most active listening. Client insight is exponentially easier to excavate when you stop “pitching” – and start listening.

Carey

Senior Sales Representative

What is your vision for the company?

Our business plan reflects the change in products DFIN is selling today versus what we sell in five years. DFIN today is a company that offers a lot of professional services that we added software to, but the goal is to become a SaaS company that has services to support it.

Stephen

SVP, Global Head of Engineering

What does your typical day look like?

The role of a software engineer is really about creating computational systems and ensuring they behave as designed. My day-to-day is focused mostly on writing code that provides new functionality within our products that we see a need for in the market—and providing quality control to be certain it works properly.
