Job Summary

We are seeking a Embedded Linux Software Engineer with experience in Embedded Linux software development for IoT products along with system validation and testing. The candidate will be responsible for developing Embedded Linux applications and features for IoT devices and gateways, integrating Zigbee/BLE solutions, performing system validation, protocol analysis, debugging, and ensuring product quality across device, gateway, cloud, and mobile ecosystems. The role also includes developing or using virtual device simulators (such as Zephyr, QEMU, or similar platforms) for application development and testing before hardware availability.

Key Responsibilities
• Develop, execute, and maintain test plans, test cases, and test reports for Linux and IoT products.
• Perform functional, integration, regression, interoperability, and system-level testing.
• Validate communication protocols such as MQTT, TCP/IP, HTTP/HTTPS, Zigbee, Matter, Thread, BLE, and Wi-Fi.

- Hands on experience in C or C++ programming.
- Hands-on experience in virtual device simulation, hardware emulation, and software-based testing environments to validate embedded firmware and IoT device functionality prior to hardware availability.
• Analyze network traffic and protocol behavior using tools such as Wireshark and packet sniffers.
• Validate device commissioning, provisioning, OTA firmware updates, and cloud connectivity.
• Perform end-to-end validation of device, gateway, cloud, and mobile application interactions.
• Develop Shell/Bash scripts for test automation, log collection, and validation activities.
• Investigate defects, perform root cause analysis, and work closely with development teams for issue resolution.




• Validate security features including authentication, encryption, certificate management, and secure communication.
• Participate in certification and compliance testing activities.
• Maintain test environments, automation frameworks, and validation setups.

Required Skills
• Good understanding of Linux systems and architecture.
• Strong Linux command-line proficiency and Shell Scripting (Bash/Sh).
• Experience in testing and validation of Linux or IoT products.
• Robust understanding of networking concepts and protocols (TCP/IP, UDP, DHCP, DNS, TLS/SSL).
• Experience using Wireshark, tcpdump, and other protocol analysis tools.
• Understanding of IoT communication protocols such as MQTT, Zigbee, Matter, Thread, BLE, and Wi-Fi.
• Experience in log analysis, troubleshooting, and root cause investigation.
• Knowledge of test methodologies including functional, regression, integration, and system testing.
• Familiarity with defect tracking tools such as Jira or Azure DevOps.
• Experience with Git and test management tools.

Preferred Skills
• Experience in Smart Home, Building Automation, Energy Management, or Industrial IoT domains.
• Experience validating Zigbee, Matter, Thread, BLE, or WiFi enabled devices.
• Knowledge of Python or Shell scripting for test automation.
• Experience with OTA validation, device onboarding, and commissioning workflows.
• Understanding of cloud-based IoT platforms and device management solutions.
• Experience with CI/CD pipelines and automated test execution.
• Familiarity with certification testing (Wi-Fi Alliance, Zigbee, Matter, Bluetooth SIG, etc.).
• Knowledge of security concepts including TLS, certificates, secure boot, and encryption mechanisms.
