Plastiq Engineer Jeff Kynaston

Meet an Engineer – Jeff Kynaston


Tell us a little about yourself.

If I’m not writing code, I’m out running around in the mountains or spending time with my family. I’m an avid skier and on powder days I take full advantage of our flexible work hours. I joined Plastiq just after they came to San Francisco, and I spent 3 years working in the SF office before moving to a remote software engineer position.

What do you do at Plastiq?

I build features across all of our UI’s and services layers, but I spend the bulk of my time in our Angular UI. I’m also the technical contact for any partner integrating into Plastiq’s payment system, and each week I spend time reviewing user behavior with the product team to identify opportunities for new features.

How did you first get into Software Engineering?

My very first scripts were macros for MMORPGs and websites dedicated to girls I had crushes on in middle school. But my first real gig building software was developing internal tools at the consulting firm I joined right out of college. From there I went on to work freelance building financial applications until I came to Plastiq.

What brought you to Plastiq?

I connected to Plastiq through a friend that knew Sean Duhame, Plastiq’s first designer. My background in finance was a good fit, and staying in the same industry made it easier for me to pick up some technologies here that were new to me.

What’s an interesting problem you have worked on at Plastiq?

A couple years back, I helped build one of the first iterations of Plastiq’s internal Risk system – an automated rules engine + UI for agents to manually research and decision payments.

How would you describe Plastiq’s engineering team?

Plastiq’s engineering team is made up of independent, full-stack engineers that are expected to think critically about the product we’re building, not just produce lines of code. Engineers naturally develop domain or subject-matter expertise across the stack and become leaders based on their knowledge and abilities. We’re proud of what we’ve built so far, and now we’re building for the future with the best technologies we can find.

Why do you enjoy your job?

  • – Peers I respect and am genuine friends with
  • – Projects and technologies that I like working with
  • – Leaders that I trust and that work hard for the company
  • – It’s the real deal, Silicon Valley, start up experience
