Matt Petitt

Engineering Manager

I'm an Engineering Manager with 15+ years of experience bridging the gap between design, development, and business. I've worked at scrappy three-person startups and global mega-corporations and learned the best from both worlds. I specialize in shipping complex UIs, design systems, and developer tools that empower organizations to build and scale high-quality experiences efficiently. I stay hands-on where it matters, balancing technical excellence with business priorities.

Currently an Engineering Manager in Dayforce's AI Platform org leading the Design Systems and Accessibility Engineering teams, where I focus on modernizing frontend infrastructure and fostering developer productivity.
