Senior Software Engineer, Backend Systems

Location:

Toronto (Hybrid preferred, remote possible for strong candidates).

This is a full-stack role with a strong backend focus.

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, platform, and smart store systems, from design through production.

Work here is end to end. That means thinking through problems, making pragmatic tradeoffs, shipping code, and improving systems over time. As we scale, there’s real ownership, real impact, and room to grow.

As a Senior Software Engineer, you’ll help evolve the core systems that power Micromart as we scale.

This is a full-stack role with a strong backend focus. Backend systems and platform reliability are the core focus, with opportunities to work across the stack as needed.

You’ll work on product features entrepreneurs rely on every day, including platform systems, AI-driven workflows, payments, fraud prevention, and real-time logic. Your focus will be on making systems more robust, reliable, and ready to support continued growth across thousands of locations.

We’re hiring one or more Senior Software Engineers as we continue to scale.

We’re driven by ambitious, mission-focused thinking and a deep commitment to earning customer trust. We value craftsmanship, simplicity, and quality, and we’re intentional about how we build, the tradeoffs we make, and the problems we choose to solve. We believe in getting things done thoughtfully, improving continuously, and working closely together to build a great product.

You’ll work on a product that entrepreneurs depend on to run their businesses. You’ll tackle high-impact technical challenges across platform systems, AI, payments, and real-time workflows. You’ll join a small team where your work has clear impact as Micromart continues to scale.
