IMI plc
We are a global specialist engineering company that creates breakthrough solutions. We are curious and like to solve problems partnering with our customers to solve the demands of today and prepare for the challenges of tomorrow. We embrace innovation and care about outcomes that are good for business everyday life and making a better world creating lasting impact for everyone.
We design build and service highly engineered products in fluid and motion control applications. We focus on five market sectors: Industrial Automation Process Automation Climate Control Life Science and Fluid Control and Transport.
Our partnership approach breaks through problems and reduces complexity. We dont invent in isolation we collaborate with our customers. We listen closely and we think differently creating space for diverse minds to innovate. We are working together to make businesses safer more sustainable and more productive.
Role Overview:
We are looking for a Firmware Engineer Zigbee Specialist to support our Heatmiser business within IMI Hydronic Engineering.
As a Firmware Engineer you will play a crucial role in developing and implementing software for industry-specific hardware.
Your expertise will contribute to the success of a cutting-edge products contributing to the future development of the Company todeliver on our growth strategy.
Key Responsibilities:
Duties will include but not limited to:
Firmware Development: Design develop code test and debug high-quality reliable embedded firmware in C/C for microcontroller-based heating control products.
Zigbee Implementation: Implement integrate configure and optimise Zigbee 3.0 (and potentially related standards like Green Power) stacks and application layer profiles (e.g. Home Automation) on target hardware platforms.
Wireless Communication: Focus on ensuring robust low-power and standards-compliant Zigbee communication including mesh networking behaviour device pairing security and interoperability.
Debugging & Testing: Utilise debugging tools (debuggers logic analysers oscilloscopes) and protocol analysers (e.g. Wireshark) to troubleshoot complex firmware and communication issues. Develop and execute comprehensive unit integration and system test plans particularly for Zigbee functionality.
Hardware Interaction: Collaborate closely with hardware engineers during the design phase participate in board bring-up and develop low-level drivers for peripherals (sensors actuators displays memory communication interfaces like I2C SPI UART).
Optimisation: Optimise firmware for performance memory usage and power consumption especially critical for battery-powered devices.
Documentation: Create and maintain clear and concise technical documentation including design specifications API definitions test procedures and release notes.
Code Quality: Participate in peer code reviews to ensure high code quality adherence to coding standards and knowledge sharing.
Standards & Compliance: Stay up-to-date with the latest Zigbee specifications and contribute to ensuring products meet relevant certification requirements (e.g. Zigbee Alliance UKCA CE).
