This role is ideal for someone who enjoys working close to hardware, building user-friendly desktop interfaces, and solving real-world device communication challenges.

Responsibilities :

- Design, develop, and maintain a Windows desktop application using React, Electron, and Node.js.

- Implement communication with IoT devices via USB (Serial communication protocols like UART/RS-232).

- Develop and manage local data storage using SQLite, ensuring data integrity and efficient access.

- Ensure cross-process communication (IPC) and hardware interaction through Electron's main/renderer processes.

- Collaborate with embedded/firmware engineers to integrate device protocols and troubleshoot issues.

- Package and deploy Windows installers using tools like Electron Builder.

- Write clean, modular code with unit and integration tests.

Required Skills :

- Strong experience with JavaScript/TypeScript, React, Node.js, and Electron as Primary Skill.

- Proven experience working with USB Serial communication (e.g., using serialport or similar Node.js libraries) and familiar with web serial API, WebUSB AP, UART Protocol implementation experience

- Knowledge of SQLite and efficient database querying for embedded/local applications.

- Familiarity with the Windows operating system and packaging desktop applications.

- Experience working with asynchronous and event-driven data streams (from devices).

- Understanding of inter-process communication (IPC) within Electron apps.

- Ability to debug and troubleshoot low-level device communication issues

Nice to Have :

- Experience with IoT protocols such as MQTT, Modbus, or BLE.

- Familiarity with other USB communication modes (CDC, HID).

- Basic knowledge of embedded systems or microcontroller firmware.

- Experience with secure data handling and encryption for local storage.

- Exposure to CI/CD pipelines and auto-updating Electron apps.
