About the Role

Our client is a fast-growing technology firm specializing in cutting-edge Internet of Things (IoT) solutions. They are looking for a highly skilled and motivated Senior Embedded Systems Engineer to join their globally distributed, remote-first team. This role is critical for the design, development, and testing of embedded software for a new generation of smart devices. You will work on complex challenges, from firmware development and hardware interfacing to system optimization and debugging. As a remote employee, you will leverage your expertise to drive innovation from your home office, collaborating seamlessly with international teams through advanced communication tools. This is an exceptional opportunity to shape the future of connected devices from anywhere.

Key Responsibilities

• Design, develop, and implement embedded software for microcontrollers and microprocessors used in IoT devices.
• Write clean, efficient, and maintainable C/C++ code for real-time operating systems (RTOS).
• Develop and maintain firmware, device drivers, and board support packages (BSPs).
• Implement communication protocols relevant to IoT (e.g., MQTT, CoAP, Bluetooth, Wi-Fi).
• Collaborate closely with hardware engineers to define system requirements and interfaces.
• Perform thorough unit testing, integration testing, and system debugging of embedded software.
• Optimize embedded systems for performance, power consumption, and memory usage.
• Work with version control systems (e.g., Git) and follow agile development methodologies.
• Contribute to the development of automated testing frameworks for embedded systems.
• Troubleshoot and resolve complex technical issues in distributed environments.

Requirements

• Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or a related discipline.
• Minimum of 7 years of professional experience in embedded systems development.
• Strong proficiency in C and C++ programming languages.
• Experience with real-time operating systems (RTOS) such as FreeRTOS, Zephyr, or VxWorks.
• Solid understanding of microcontroller architectures (e.g., ARM Cortex-M).
• Familiarity with common communication protocols for IoT devices (Wi-Fi, Bluetooth, Zigbee, LoRaWAN, MQTT).
• Experience with debugging tools (e.g., JTAG, oscilloscopes, logic analyzers).
• Proficiency with version control systems like Git.
• Excellent problem-solving, analytical, and debugging skills.
• Strong written and verbal communication skills, essential for a remote role.
• Experience with hardware-software integration and system-level debugging.

Benefits

Our client offers a highly competitive salary and benefits package, designed for remote employees. This includes a generous annual salary, potential for stock options, and a comprehensive health insurance plan. Employees are provided with a budget for home office setup and continuous professional development opportunities, including online courses and conference attendance.
