Job summary

Micromart is seeking a System Validation Engineer in Toronto to own end-to-end validation across hardware, edge devices, and software. You will simulate real-world conditions, analyze failures, and drive root-cause fixes with engineers and partners to ensure reliability in a fast-paced, scalable unattended retail platform.

You will work with Linux-based systems, Android builds, and TypeScript/Node.js tooling, contributing to long-term improvements in hardware selection, firmware updates, and

Qualifications

• Experience with hardware and software systems such as IoT devices, embedded Linux systems, or device fleets
• Strong debugging skills on Linux-based devices (logs, processes, memory usage, networking)
• Familiarity with device-level components such as USB cameras, routers, SIM connectivity, and embedded Linux systems
• Solid understanding of networking fundamentals (DNS, DHCP, NAT, connectivity troubleshooting)
• Ability to reason about distributed systems where hardware, edge services, and cloud APIs interact
• Comfort taking ownership in a fast-paced startup environment

Responsibilities

• Own QA for features that cross hardware and software boundaries, including smart locks, payment terminals, cameras, eTags, edge devices, and Android builds
• 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 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
• Test and compare different hardware components including edge computers, USB cameras, payment terminals, and networking equipment
• Evaluate performance, stability, and compatibility across vendors and configurations
• Propose and validate improvements to hardware selection and system architecture
• Identify tradeoffs between cost, performance, and reliability in real-world deployments
• 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
• 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
