Data Infrastructure Engineer

Greenfield Labs is the Canadian R&D Hub for Zenreach

Zenreach was created to solve one of the most important problems in the modern economy—the majority of our time is being spent online, yet over 93% of purchasing still happens offline — and there is no link between the two systems. Brick-and-mortar merchants are working decades behind their online counterparts without essential data and tools. We created Zenreach to give them the same level of technology and transparency that anyone operating online has come to expect.
