Location: Noida
Experience: 3–5 years
Work Schedule: Full-Time

We’re hiring a Firmware Design Engineer to develop, test, and optimize embedded firmware for next-generation electronic products.

As the Firmware Design Engineer, your responsibilities would be:
- Design, develop, and maintain real-time embedded firmware in C/C++ using RTOS (FreeRTOS, ThreadX, Zephyr) for microcontrollers and processors.
- Implement device drivers (UART, SPI, I2C, I2S, ADC/DAC, USB) and integrate low-power firmware for battery-operated devices.
- Develop and integrate wireless stacks including Bluetooth (Classic & BLE), WiFi, RF subsystems, and handle OTA updates.
- Build audio processing pipelines, manage digital audio interfaces (I2S, PDM, PCM), ANC/ENC systems, and low-latency audio.
- Perform board bring-up, hardware-software integration, system debugging (JTAG, SWD, Oscilloscope), and root cause analysis.
- Optimize firmware for power consumption, memory footprint, and CPU utilization while maintaining coding standards and documentation.

Requirements




- Strong programming skills in Embedded C/C++ with ARM Cortex-M or RISC-V microcontrollers.
- Hands-on experience with RTOS-based development, hardware protocols (SPI, I2C, UART, USB), bootloaders, and OTA updates.
- Experience with Bluetooth Classic/BLE, WiFi stack integration, and RF communication subsystems.
- Background in low-power architecture, battery management, and ultra-low-power design for wearable or hearable devices.
- Proficiency with debugging tools (JTAG, SWD, Logic Analyzers) and build environments (Git, Keil, STM32CubeIDE, VS Code).
- Ability to read hardware schematics/datasheets and perform hardware-software board bring-up.

Benefits
- Work with cutting-edge wireless, audio, and next-gen wearable/hearable technologies.
- Be part of a cooperative, innovation-driven work culture with strong growth opportunities.
- Gain hands-on exposure to market-leading SoCs (Nordic, Qualcomm, NXP, STM, TI) and LE Audio developme
