## About the Role

We're looking for an experienced Embedded Software or Firmware Engineer with strong commercial experience developing software for physical engineering products.

You'll ideally have:

 * Strong hands-on development experience with C and C++
 * Commercial embedded software or firmware development experience
 * Experience with ARM-based processors, STM32 or comparable microcontroller platforms
 * Strong understanding of embedded software architecture and development practices
 * Experience working close to hardware and with common microcontroller peripherals
 * Knowledge of interfaces and protocols such as SPI, I2C, UART, CAN, Ethernet, RS485 or RS232
 * Strong debugging, testing and problem-solving skills
 * Experience developing reliable embedded systems
 * Experience working within multidisciplinary engineering teams
 * The ability to take technical ownership rather than simply work from predefined requirements
 * Strong communication skills and the ability to explain technical concepts clearly
 * An interest in mentoring and supporting other engineers

A degree in Software Engineering, Electronic Engineering, Computer Science or a related discipline would be beneficial, although equivalent commercial experience will also be considered.

Candidates must already have the right to work in the UK without requiring visa sponsorship.

## Description

As Senior Embedded Software Engineer, you'll take a leading technical role across the architecture, design, development, testing and continuous improvement of embedded software.

This remains a highly hands-on engineering position, but with greater ownership and influence than a typical development role. You'll help shape embedded software architectures, solve complex technical challenges and take software through the full lifecycle from initial concept to commercial delivery.

You'll also act as a senior technical presence within the team, supporting less experienced engineers and helping drive strong software engineering practices., * Design, develop and maintain embedded software using C and C++

 * Develop software for ARM-based processors and STM32 microcontrollers
 * Define and contribute to embedded software architectures for new and existing products
 * Develop reliable embedded applications for complex engineering environments
 * Work closely with hardware and microcontroller peripherals including USB, I2C, SPI, UART, DMA, ADC and DAC
 * Develop firmware for communication interfaces including Ethernet, RS485, RS232 and CAN
 * Debug, test, validate and continuously improve embedded software
 * Evaluate new software technologies and their potential application within products
 * Produce high-quality technical documentation
 * Coordinate and plan technical development activities
 * Take ownership of technical problems through to resolution
 * Provide technical guidance and mentoring to less experienced engineers
 * Work closely with engineers from other disciplines throughout the product development lifecycle
 * Help promote engineering best practice and continuous improvement across the team
