- Perform functional, regression, integration, and end-to-end testing across hardware, firmware, backend, and frontend components.
- Work closely with firmware, hardware, and software teams to investigate and troubleshoot issues across the full technology stack.
- Fix small bugs and UI issues in the React / Next.js frontend and Node.js backend where appropriate.
- Use APIs, logs, device data, and debugging tools to identify the likely source of issues.
- Support the improvement of testing processes, test coverage, documentation, and overall product quality as the platform grows.

Key Responsibilities

- Basic to positive knowledge of JavaScript, React / Next.js, and Node.js.
