About the Role

We have opportunities for ambitious Embedded Software Engineers at Principal level to join our multidisciplinary engineering team at the forefront of additive manufacturing technology.

Our embedded software platforms are central to the control sensing communication monitoring and real-time processing capabilities of our next-generation products. Working within Research & Development you will contribute to the full product lifecycle from concept and architecture through verification release to production and long-term support.

These are hands-on engineering roles combining embedded software development debugging and verification with close collaboration across electronics FPGA systems algorithms and mechanical engineering teams. Depending on experience and grade you will also provide technical leadership influence engineering strategy and mentor developing engineers.

The software frequently interacts with microcontrollers FPGAs sensors communication networks and analogue electronics. As such a strong appreciation of system-level design and hardware/software interaction is essential.

• Extensive experience leading the architecture and development of complex embedded products.

• Recognised expertise in embedded software real-time systems and hardware/software integration.

• Track record of influencing engineering strategy and technology direction.

• Strong capability in technical leadership across multiple programmes and engineering disciplines.

• Experience defining engineering processes software standards and verification methodologies.

Desirable Requirements

• Experience with ARM Cortex-M microcontrollers and associated development environments.

• Knowledge of C Python or scripting languages used for automation and testing.

• Experience implementing industrial communication protocols such as EtherCAT Modbus CANopen or IO-Link.

• Experience with Git Azure DevOps and CI/CD workflows.

• Familiarity with unit testing frameworks and static analysis tools.

• Understanding of control systems signal processing and numerical algorithms.

• Knowledge of FPGA-based systems and hardware/software partitioning.

• Experience of high-speed digital electronics EMC and mixed-signal systems.

• Experience working within regulated or safety-conscious product development environments.

Person Specification

You are a passionate and capable engineer who enjoys solving complex technical challenges and delivering robust high-quality products.
