## Description

You'll work closely with electrical, hardware, systems, and software engineers to develop reliable firmware for low-power, connected, and battery-operated devices. The role is well suited to an experienced embedded engineer who enjoys solving challenging technical problems and seeing their work become part of real-world products.

What You'll Do

 * Design, develop, test, debug, and optimize embedded firmware for microcontroller-based systems.
 * Develop software in embedded C/C++ for low-power and connected devices.
 * Work with both bare-metal and RTOS-based firmware architectures.
 * Develop and integrate Bluetooth Low Energy (BLE) and other wireless connectivity solutions.
 * Work with communication technologies and protocols including Wi-Fi, Zigbee, and cellular connectivity.
 * Develop firmware for battery-powered and power-constrained products, with a focus on efficiency and reliability.
 * Work with microcontroller peripherals and interfaces including I²C, SPI, GPIO, ADC, CAN, and UART.
 * Collaborate closely with hardware and electrical engineers to bring products from concept through development and production.
 * Read and interpret schematics, datasheets, and hardware specifications.
 * Perform firmware verification, troubleshooting, analysis, and optimization.
 * Use tools such as oscilloscopes, logic analyzers, debuggers, and other test equipment to diagnose hardware and software issues.
 * Contribute to technical requirements, architecture, design decisions, and engineering documentation.
 * Help identify and resolve complex system-level issues across hardware and software.
