Job Title: Firmware Design Engineer

Location: Noida

Experience: 3 to 5 years

Qualification: Bachelor’s or Master’s degree in Electronics & Communication, Electrical, Embedded Systems, or Computer Engineering

Work Schedule: Full-Time

We’re hiring a Firmware Design Engineer to design, develop, and optimize next-generation electronic products, with a focus on wireless, audio, hearables, and wearables. 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
- Solid 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
