Insider's spotlight

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

One of the best parts about working at Signal is the flexibility. I am a busy mom of two, with tight timelines and clients and team members in all time zones. I feel lucky that somehow, I still get to spend time with my family, and find time for myself.


SVP Global Client Delivery

What projects are you most excited about?

As developers at Signal, we’re given the opportunity to be creative and tackle interesting problems. We work in a challenging domain, but are given the freedom and flexibility to solve problems in new and creative ways, with the best tools and technologies for the project at hand.


Director of Engineering

How does the company support your career growth?

I was hired as an apprentice at Signal because of my potential and drive to start something new. Since then, I’ve been able to scope, work on and lead my own project, and it hasn't even been a year since I started! I'm eager to see where I go from here.



The summer outing is a highly-anticipated event. Last year, it was an Amazing Race-inspired competition with a booze cruise as an epic final destination. It’s fun to partner with Signalites I don’t normally interact with at work, and learn who they are outside of the office.
