Ready to Code the Future of Everyday Tech?

One of our client's is building the invisible intelligence inside tomorrow’s smart consumer devices, and looking for a Firmware Engineer who thrives at the intersection of embedded systems, low-level optimization, and user-facing innovation.

Join their collaborative team developing devices for gesture recognition, voice control, and context-aware automation — all powered by ARM Cortex-M microcontrollers.

What You’ll Do

• Design and develop firmware for Cortex-M4/M33 MCUs, with a focus on gesture, audio, and sensor data processing
• Work closely with hardware, mobile, and cloud teams to integrate embedded functionality across platforms
• Optimize code for real-time performance, power efficiency, and memory usage
• Use FreeRTOS, Zephyr, or bare-metal systems depending on project needs
• Write unit tests, perform debugging, and participate in code reviews

Must-Have Skills

• Strong experience programming C/C++ in embedded systems
• Hands-on experience with ARM Cortex-M4/M33 firmware development
• Familiarity with FreeRTOS, CMSIS, or similar frameworks
• Knowledge of SPI, I2C, UART, and sensor integration
• Comfort with oscilloscopes, logic analyzers, and hardware bring-up

Bonus Points For

• Experience with TinyML or signal processing (gesture/audio use cases)
• Familiarity with OTA updates, low-power design, or BLE protocols
• Past work on consumer electronics, wearables, or IoT devices
• Exposure to CI/CD pipelines or automated testing for embedded systems
