Embedded Firmware Engineer

Position Overview
We are looking for an engineer to develop and optimize firmware for embedded platforms, working closely with hardware and cross-functional teams. The role involves end-to-end development, performance tuning, and enabling intelligent features on edge devices with a focus on efficiency and reliability.

Key Responsibilities

• Design and develop embedded firmware and software using Embedded C, C++, and Python.
• Develop bare-metal and FreeRTOS drivers and application logic across MCU (ESP32-C6/P4, STM32-class) and embedded Linux (Quectel SC60 Yocto BSP) targets.
• Work on microcontrollers, peripherals, and hardware interfaces.
• Bring up new boards from scratch — read and interpret schematics, verify signals and power rails, and develop firmware directly against the design.
• Develop and integrate communication interfaces like UART, SPI, I2C, USB, PCIe, and Ethernet.
• Implement device connectivity and cloud communication — Wi-Fi, BLE, LTE/cellular, MQTT — including onboarding, provisioning, and OTA/FOTA flows.
• Debug and troubleshoot embedded systems using tools like debuggers, oscilloscopes, logic analyzers, and JTAG/SWD.
• Develop functional and unit tests, validate firmware functionality, and automate the same (including hardware-in-the-loop).
• Analyze system performance and optimize code for memory, power, and real-time constraints.
• Participate in the full development lifecycle: design, coding, testing, and debugging.
• Create prototypes to validate design concepts.

Required Qualifications

• 1–3 years of experience in embedded software/firmware development.
• Strong programming skills in Embedded C, C++, and Python.
• Hands-on experience with FreeRTOS and working experience with Linux/RTOS.
• Bare-metal firmware development (no OS) — direct register access, startup code, and peripheral drivers.
• Good understanding of embedded systems architecture.
• Experience with hardware interfaces like UART, SPI, I2C, USB, PCIe, and Ethernet.
• Strong understanding of memory management and real-time constraints.
• Ability to read and interpret hardware schematics and component datasheets, and develop firmware directly against the board design.
• Strong hardware debugging skills - able to root-cause issues at the hardware/firmware boundary using an oscilloscope, logic analyzer, multimeter, and JTAG/SWD.
• Strong debugging and problem-solving skills.
• Familiarity with development tools like compilers, debuggers, and version control (Git).
• B.E./B.Tech in Electronics, Electrical, Computer Science, or a related field.

What We Look For
Curiosity to open the box, read the datasheet, and figure out why it broke.
Ownership — you follow a feature from idea to shipped firmware.
Clear communication and a collaborative, review-driven approach to code.
