System Validation Engineer

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 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 escalate 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

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

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

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

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

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.
