## About the Role

We're interested in talented engineers who enjoy solving challenging technical problems and developing reliable embedded software.

You'll ideally have:

 * Strong commercial experience developing embedded software in C/C++.
 * Experience working with bare-metal systems and/or real-time operating systems.
 * Experience developing software for ARM Cortex-based microcontrollers.
 * Practical experience bringing up prototype hardware.
 * Knowledge of embedded communication protocols including Ethernet, CAN, SPI, I²C and UART.
 * Excellent debugging skills using both hardware and software tools.
 * A degree in Computer Science, Electronic Engineering or a related discipline, or equivalent commercial experience.

Experience in any of the following would be advantageous:

 * Zephyr RTOS or FreeRTOS
 * STM32 microcontrollers
 * Embedded networking and TCP/IP
 * Secure bootloaders and firmware update mechanisms
 * Python
 * MISRA C/C++
 * RF or microwave systems
 * Defence, aerospace or space applications, Above all, we value enthusiasm, curiosity and a willingness to learn. If you don't meet every requirement but believe you have the skills and attitude to succeed, we'd still love to hear from you.

## Description

* Developing embedded software in C/C++ for ARM-based microcontrollers.
 * Designing software for bare-metal and real-time operating systems, including FreeRTOS and Zephyr.
 * Bringing up new hardware and debugging prototype boards using oscilloscopes, logic analysers and software debugging tools.
 * Developing robust communications between embedded devices using interfaces such as Ethernet, CAN, SPI, I²C, UART and RS422.
 * Designing networking functionality including TCP/IP, REST APIs, SNMP and OpenAPI interfaces.
 * Working closely with hardware, FPGA and systems engineers to integrate software with complex electronic systems.
 * Investigating and resolving software, networking and embedded system issues.
 * Contributing throughout the full product development lifecycle from concept through to manufacture.
