Job description

Location: Toronto (Hybrid. Regular in-office presence required for hardware testing.) A hands-on technical role focused on validating, stress-testing, and strengthening the full hardware-software systems that power our autonomous retail platform.

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 changes, and improving systems over time. As we scale, quality and reliability matter more than ever, and this role plays a key part in that.

How you can help

As a Hardware Systems Reliability Engineer, you will define what reliability means at Micromart across the full hardware and software system.

You will own system-level QA and release confidence for changes that impact hardware, edge devices, payments, vision systems, and connected components. When a feature crosses hardware and software boundaries, this role ensures it works in the real world.

This is a systems-first role that combines hands‑on validation with reliability‑focused engineering work. You will spend time testing cabinets, simulating real‑world conditions, reproducing failures, analyzing logs, validating Android builds and device‑side changes, and working closely with engineers and external partners to continuously raise the reliability bar.

Our smart stores operate 24/7. Entrepreneurs and shoppers depend on them to work every time.

At Micromart, you will

Own System-Level Validation

• Own QA for features that cross hardware and software boundaries, including smart locks, payment terminals, cameras, eTags, edge devices, and Android builds that interact with physical systems
• Define and enforce what “release ready” means for hardware and edge system changes
• Develop and refine hardware and systems validation procedures as architecture evolves
• Ensure firmware updates, BIOS changes, hardware revisions, and vendor SDK changes do not introduce regressions before rollout

Test Real-World Conditions

• Test end-to-end flows across hardware, embedded Node.js services, networking infrastructure, payments, vision processing, and cloud APIs
• Simulate real-world scenarios such as internet loss, degraded connectivity, Bluetooth instability, USB device failures, power interruptions, and router instability
• Validate revenue‑impacting systems including payment authorization flows and vision‑based order processing under real‑world conditions

Investigate and Resolve Field Issues

• Reproduce customer‑reported and fleet issues in a controlled environment
• Investigate issues such as payment preauthorization failures, vision detection or review inconsistencies, temperature alarms, memory leaks, LCD burn‑in, USB device instability, and connectivity problems
• Analyze logs and fleet health data to determine root causes and quantify impact across deployments
• Document findings clearly and partner with engineering to drive long‑term fixes

Improve Reliability and Support Engineering

• Collaborate directly with technology partners to elevate issues and validate fixes
• Collect and provide structured technical evidence to support investigations
• Build small tools or scripts to improve fleet visibility and diagnostics
• Contribute targeted reliability improvements directly to device‑side services and infrastructure, including writing and shipping code changes in TypeScript, Node.js, or related tooling when appropriate
• Partner closely with engineers to design and implement long‑term fixes for systemic reliability issues

Technology Stack

You will work across a distributed system that includes:

• Linux-based edge computers running Node.js services (TypeScript)
• Android applications interacting with device‑side services
• USB cameras, Bluetooth eTags, payment terminals, routers, and other connected hardware
• Cloud APIs and backend services built in TypeScript
• Fleet management and remote device monitoring tools

What you bring to the team

• Experience working with hardware and software systems such as IoT devices, robotics platforms, embedded Linux systems, or device fleets
• Strong software fundamentals and comfort reading, understanding, and debugging production code, ideally in TypeScript or Node.js
• Experience debugging issues on Linux‑based devices including logs, processes, memory usage, and networking behavior
• Familiarity with device‑level components such as USB cameras, routers, SIM connectivity, and embedded Linux systems
• Solid understanding of networking fundamentals including DNS, DHCP, NAT, and connectivity troubleshooting
• Strong investigative mindset with a focus on root cause and durable solutions
• Ability to reason about distributed systems where hardware, edge services, and cloud APIs interact
• Comfort taking ownership in a fast‑paced startup environment

Nice to have

• Experience with Raspberry Pi or embedded Linux systems
• Experience validating firmware updates
• Experience working with payment devices or IoT fleets
• Ability to write tooling in TypeScript, Bash, Python, or C
• Experience working with embedded or edge computing devices with hardware acceleration or vision processing workloads
• Experience in high‑uptime, real‑world production systems
• Startup or high‑growth company experience

Our Values

We are driven by ambitious, mission‑focused thinking and a deep commitment to earning customer trust. We value craftsmanship, simplicity, and quality, and we are intentional about how we build and the problems we choose to solve.

• We are problem solvers first, builders second
• We care deeply about durability and real‑world reliability
• We value ownership and accountability
• Reliability and security are non‑negotiable
• We move fast, but we build to last

Why Micromart

Quality and reliability are foundational to Micromart’s platform. Our smart stores operate continuously, and entrepreneurs and shoppers depend on them to work every time. This role directly impacts uptime, customer trust, and system resilience. You will not just test features. You will define and raise the reliability standard across thousands of real‑world deployments.

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. Your work will directly support that mission.

This year marks a major growth phase for Micromart. We’ve built the core smart store product and the platform that powers it with a very small team. Now we’re focused on scaling, shipping new 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.

• 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
