As we expand our platform capabilities, we are looking for passionate and skilled engineers to help us build robust, user-friendly, and scalable applications that drive real-world impact. Key Responsibilities: Design, implement, and maintain firmware in C and C++ for resource-constrained embedded systems. Architect complete embedded system solutions for new hardware products?including MCU selection, peripheral mapping, memory planning, and power constraints. Define hardware-software interfaces, communication architectures, board-level requirements, and system workflows. Lead feasibility studies for new product ideas, evaluating sensors, wireless modules, and embedded platforms. Collaborate with hardware designers to co-create system schematics, pinouts, and high-level architecture diagrams. Work closely with the hardware team for board bring-up, debugging, and manufacturing readiness. Ensure excellence in quality of both hardware and firmware developed Implement and optimize communication protocols (I?C, SPI, UART, GPIO, TCP/IP, MQTT). Integrate and test wireless stacks (LoRaWAN, LTE, GSM, BLE, Wi-Fi, GPS/GNSS). Build robust device?cloud and device?gateway communication flows for production systems. Document system architecture, firmware design patterns, APIs, communication protocols, and hardware dependencies. Collaborate with QA, backend, and hardware teams for end-to-end product validation. Drive continuous improvements in reliability, test coverage, architecture scalability, and embedded quality processes. Required Skills & Qualifications: Expert in embedded C/C++, modern coding practices, memory optimization, and DSA concepts. Proven experience designing and owning firmware architecture for complex products. Strong skills in debugging hardware?firmware issues using advanced tools (DSO, logic analyzer, SWD/JTAG).
