Job Description
Principal Embedded Software Engineer (C)
Up to £70,000 depending on experience
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.
Key Responsibilities
-
Embedded Software Development
- Develop embedded software architectures and applications from concept through to production release.
- Design, implement, and maintain high-quality C software with a focus on performance, reliability, maintainability, and portability.
- Develop low-level drivers, middleware, and application-layer software for embedded systems.
- Implement communication interfaces such as SPI, I²C, UART, CAN, Ethernet, and industrial communication protocols.
- Optimise software for real-time performance, memory usage, and deterministic behaviour.
- Support product sustainment, issue investigation, and software improvements throughout the product lifecycle.
- Develop reusable software frameworks and libraries for use across multiple projects and product generations.
-
Verification & Validation
- Develop robust software verification strategies covering unit, integration, and system-level testing.
- Create automated test frameworks and regression test suites.
- Define verification plans, acceptance criteria, and coverage objectives.
- Support hardware-in-the-loop, system integration, and product validation activities.
- Drive continuous improvement in automated testing, continuous integration, and software quality metrics.
- Investigate and resolve complex software and system-level defects.
-
Systems & Product Development
- Capture, analyse, and refine requirements, ensuring clear traceability from customer and system requirements through to implementation and verification.
- Work closely with systems, electronics, FPGA, algorithms, and test engineers to deliver integrated solutions.
- Evaluate and implement control, signal processing, and embedded algorithms on target hardware platforms.
- Contribute to safety, reliability, and compliance activities, including design assurance and audit-ready engineering evidence.
- Produce and maintain high-quality technical documentation, including software architecture specifications, interface definitions, design descriptions, and verification reports.
