Micromart is building the platform for unattended retail. We empower entrepreneurs to turn any location into a retail opportunity, from offices and condos to gyms, hotels, and other shared spaces. Our focus is on giving entrepreneurs powerful tools that are simple to use, while delivering a fast, intuitive shopping experience for shoppers.

Often described as Shopify for physical commerce, Micromart provides the infrastructure that powers unattended retail in the real world.

Micromart launched just over a year ago and is now used in thousands of locations across North America. We’re a small and growing team working closely across product, frontend, backend, and smart store systems, from design through production.

Work here is end to end. That means starting from real customer problems, making pragmatic tradeoffs, shipping code, and improving the product over time. As we scale, there’s real ownership, real impact, and room to grow.

You’ll work across our operator platform (web), in-store POS (React Native), mobile experiences, customer touchpoints, and supporting internal tools. You’ll collaborate closely with product and backend engineers to design and build intuitive, reliable workflows.

Your focus will be on solving real customer problems and making complex operational tools feel simple, fast, and trustworthy as the platform continues to scale.

We believe in getting things done thoughtfully, improving continuously, and working closely together to build a great product.
