The World Leader in Radar Traffic Control

42Square (A Wavetronix company) creates innovative tools that help improve traffic on the world’s roads. Our advanced radar offers unmatched performance and is changing the ITS industry by raising the standard for excellence in vehicle detection at intersections and roadways around the globe.

Our core purpose is to enable rewarding careers and foster personal development while engineering the best traffic detection technologies possible. We fulfill this purpose by putting people first and focusing on personal growth. We lead with insight and innovation; seek out, embrace and solve difficult challenges; and strive to change the way our customers approach their problems. Because of this, we continue to enjoy strong growth, investing in long-term ideas to create even more opportunities.

Intersection

Wavetronix brings next-generation intersection detection through the combined power of SmartSensor Matrix and SmartSensor Advance, creating a complete radar-based solution that enhances both stop-bar accuracy and approach safety.

Expanse

A whole new way to access powerful sensor network management. Expanse combines non-intrusive radar sensors with next generation cabinet devices to create a unique, unified user experience, all on a platform that continuously evolves and expands.

Motorways

Wavetronix’s flagship radar detector for freeway and arterial traffic applications. Mounted above the roadway, it eliminates the need for intrusive in-road sensors, reducing maintenance and installation costs.

CrossRoads

An innovative animation and simulation tool that allows you to quickly see how to improve your intersections. Interactive and customizable, CrossRoads lets you animate your intersection; simulate a seamless connection between non-intrusive detection and intersection controllers; and see the potential benefits you could reap under different conditions.

People First. Always.

We are People First—not as a tagline, but as a principle. We don’t believe in burning out talent or glorifying chaos. We believe in giving our people the space to think, to build, and to do the best work of their lives—without noise, ego, or politics. We trust each other, hold each other to high standards, and treat one another like adults. It’s a culture of high trust, not high maintenance. Respect here means feedback, ownership, and showing up with purpose.

But 42Square isn’t just about work. It never was. We built this place to be more than a company. We wanted it to feel like a team, a gathering, a space where people actually enjoy being together. Because having fun isn’t a distraction from the work. It’s part of it.

A place to work
and a place to be.

Our office is world-class—but it doesn’t feel like a showroom. It feels like home. Thoughtfully designed spaces, cozy corners, quiet zones, and spots to gather when inspiration strikes. It’s a place where great work happens—but also where you can sip coffee in peace, have real conversations, and feel like you belong the moment you walk in. It’s more than a workplace—it’s where our culture lives.

About Us

In 2024, 42Square joined Wavetronix—a global leader in traffic technology—to bring our craft and culture to a broader mission. While our reach has grown, our values remain the same: people first, growth mindset and innovation driven.
We are an engineering company that is more than just engineers. We are scientists, researchers, teachers, technicians, assemblers, machinists, software developers, creatives, writers, accountants, salespeople, landscapers, culinary experts, and custodians; we are dreamers and visionaries and builders, all working together to create something extraordinary.

Our leaders set the direction, clear the path, and let people do great work. No micromanaging. No noise. Just steady support, honest feedback, and a space to build, learn, and grow.

“Hire great people and give them freedom to be awesome.”

Andrew Mason

We hire slowly-
on purpose.

Because the people we bring in shape our culture, our product, and how we work together every day. A great hire can quietly lift the whole team. We look for alignment—not just in skills, but in values, pace, and mindset. Our philosophy is simple — We hire for heart and craft—and build a culture that puts people first, always.

Our culture is calm, focused, and built on trust. No micromanaging. No noise. Just kind, thoughtful people who care about what they’re building and who they’re building it with.

If this sounds like a place you'd want to be, write to us at hr@42square.ai. We’d love to meet you. We’ll have real conversations, give you space to think, and help you figure out if this feels like home—somewhere you’d genuinely want to be.
