Job description

This is a frontend focused role, with opportunities to contribute across the stack as part of building end to end product experiences.

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, 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.

How you can help

As a Senior Frontend Engineer, you’ll help shape the primary product surfaces entrepreneurs use to run their businesses.

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.

At Micromart, you will

• Build and evolve core product experiences across our operator platform (web), in-store POS (React Native), mobile apps, customer touchpoints, and supporting internal tools
• Own frontend features end to end, from implementation through production and iteration
• Work closely with product and backend engineers to shape workflows and APIs
• Build interfaces that balance power and simplicity for real operational use cases
• Build and evolve data-rich, real-time frontend experiences for operational and in-store use cases
• Improve frontend architecture, performance, and maintainability over time
• Make pragmatic tradeoffs that prioritize clarity, usability, and long-term quality
• Build with a high quality bar, catching edge cases through careful implementation, testing, and iteration

What you bring to the team

• Strong experience building and owning production frontend applications
• Strong fundamentals in frontend architecture, state management, browser behavior, and API integration
• Comfort debugging complex frontend issues, including performance, memory, and production bugs
• Experience with modern frontend technologies such as React, React Native, and TypeScript
• Experience building complex React-based products, including admin-style dashboards or operational interfaces
• Comfort working with real production data and complex workflows
• Strong product instincts and attention to UX details
• A bias toward simplicity, quality, and continuous improvement

Nice to have

• Experience working on data-heavy or real-time applications
• Experience building mobile applications
• Familiarity with tools like TanStack / React Query, MUI, or similar
• Familiarity with design systems or frontend platform work
• Experience with frontend test automation (e.g., Cypress)
• Experience working with operational workflows or systems that support real-world processes
• Strong product and UX sensibilities, with the ability to collaborate effectively with design
• 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 tools that real entrepreneurs and shoppers depend on every day. You’ll help shape product experiences used across thousands of locations, from operator tools to in-store and mobile experiences. You’ll join a small team where frontend is central to the product and your work has clear, visible impact.

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
• Centrally located downtown office near Union Station
