Location: Gurugram
Company: CITiLIGHT
CITiLIGHT is seeking a IoT QA Engineer to ensure that our smart lighting hardware and software work together reliably in real-world deployments. In this role, you will be responsible for testing IoT devices end-to-end through our software platform, verifying device commands and data, investigating issues, and supporting the continuous improvement of product quality.
The ideal candidate brings a logical and structured approach to problem-solving, strong attention to detail, and an eagerness to learn across IoT, hardware, networking, and software. This role is hands-on and requires close collaboration with firmware, hardware, and software teams to identify, reproduce, troubleshoot, and resolve issues across the full stack.
Key Responsibilities:
- Test IoT devices including NEMA, Zhaga, pole-mount controllers, CCMS, and related systems end-to-end through the software platform.
- Verify that commands such as switching, dimming, and scheduling reach devices correctly.
- Validate that device data including status, energy, alarms, and other telemetry is accurately reflected on the platform dashboard.
- Write and execute test cases for new features, software releases, and firmware updates.
- Find, reproduce, and clearly document bugs using steps to reproduce, logs, screenshots, and other relevant evidence.
- 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.
Requirements:
- Basic to good knowledge of JavaScript, React / Next.js, and Node.js.
- Strong logical and structured problem-solving ability, with an interest in understanding why an issue occurred rather than only identifying that it occurred.
- Ability to write, execute, and document clear and repeatable test cases.
- Strong attention to detail and clear written communication.
- Eagerness to learn IoT, hardware, networking, software platforms, and related technologies as required by the problem.
- Hands-on attitude and comfort working with physical IoT devices and equipment in a lab environment.
- Ability to investigate issues using logs, screenshots, APIs, device data, and basic debugging tools.
- Basic understanding of REST APIs, MQTT, or IoT device communication.
- Exposure to Git/version control in a collaborative development environment.
- Ability to work closely with hardware, firmware, backend, frontend, and QA stakeholders.
- Willingness to work onsite at the CITiLIGHT office in Delhi.
Soft Skills (Critical for Success):
- Ownership mindset: Takes responsibility for assigned testing and issue-resolution activities.
- Team collaboration: Works seamlessly with hardware, firmware, software, and QA teams.
- Clear communicator: Documents issues clearly and communicates technical findings effectively.
- Problem solver: Approaches failures systematically and investigates root causes.
- Eager to learn: Open to feedback, continuous improvement, and learning new technologies.
- Adaptable & hands-on: Comfortable switching between software, hardware, testing, and troubleshooting tasks.
Soft Skills (Critical for Success):
- Experience with manual or automated testing tools such as Postman, Jest, Cypress, Playwright, or similar.
