About Micromart

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.

Our Team

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.

How you can help

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.

At Micromart, you will

• Design, build, and maintain backend systems
• Work on product integrations, operational tooling, and reliability improvements across backend services, APIs, and supporting systems
• Work on payment systems, fraud prevention, device management, and real-time services
• Build and evolve internal tools and workflows used by operators and internal teams
• Own systems end to end, from design and implementation through deployment and production support
• Collaborate closely with product, frontend, and smart store teams
• Make pragmatic tradeoffs that prioritize clarity, quality, and long-term maintainability

What you bring to the team

• Strong experience building, owning, and operating production software systems
• Experience working within large codebases or monorepos and improving architecture incrementally over time
• Solid backend and systems fundamentals, including Node.js, TypeScript, and relational databases such as Postgres
• Experience working across the stack, including modern frontend frameworks such as React
• Familiarity with modern SDLC practices, including CI/CD, automated testing, code reviews, and building secure, production-quality systems
• Comfort working through ambiguity and real-world constraints
• A bias toward simplicity, craftsmanship, and continuous improvement

Nice to have

• Experience with payment systems and financial workflows
• Experience with platforms, infrastructure, or distributed systems
• Experience building systems that interact with real-world devices or real-time events
• Background in startups or small teams where ownership mattered more than process

Our Values

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.

Why Micromart

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.

We believe software should empower people to build real businesses in the physical world. Micromart exists to give entrepreneurs practical, durable tools to create opportunity where people live and work, and your work will directly support that.

This year marks a major growth phase for Micromart. We’ve achieved a lot with a very small team, built the core smart store product and the platform that powers it, and are now focused on scaling, shipping new product capabilities, and raising the bar on product quality and our technical stack. If you enjoy owning real systems and pushing them to the next level, there’s a lot to dig into.

What We Offer

• Competitive salary and equity
• Health, dental, and vision benefits for employees and dependents
• Monthly fitness or wellness stipend
• Hybrid work environment, with access to our Toronto office
• Meals provided when working from the office
• A centrally located downtown office near Union Station
