Embedded Software Engineer

PROIV is a mature, enterprise-grade low-code platform used by internal and external customers to build scalable, data-driven business applications where reliability and long-term maintainability are critical. The Core Engineering team is a small, highly experienced group responsible for evolving the platform’s foundational technology, including the C++-based PROIV Kernel and the Windows Developer IDE. This role focuses on developing and maintaining the core C/C++ codebase, modernising legacy code, and supporting build, test, and automation infrastructure.

The team works collaboratively, follows modern engineering practices such as TDD, code reviews, CI, and secure coding, and is actively modernising its tooling and processes. This is an opportunity to contribute to a globally deployed product while helping shape a forward-looking engineering culture.

In this role your key responsibilities will be:

* Contributing to the development and maintenance of the core C/C++ codebase, to support the ongoing evolution of the PROIV Kernel.

* Improving and modernising legacy C code using modern C++ practices, to enhance performance, maintainability, and scalability

* Learning and applying the PROIV language and environment, to support wider platform development when required.

* Supporting and maintaining build tools and automation scripts, such as CMake and Python, to streamline development and testing workflows.

* Writing clear, maintainable, and testable code, to ensure long-term code quality and ease of collaboration.

* Participating in peer code reviews, to share knowledge and uphold coding standards.

* Collaborating with quality assurance colleagues, to embed testing earlier in the development process.

* Working independently to identify and resolve technical challenges, to maintain momentum and reduce bottlenecks.

* Contributing to the continuous improvement of tools, processes, and delivery practices, to enhance team productivity and software quality.

* Embedding modern software engineering practices across the team, to support a culture of technical excellence.

Skills & Experience

* Strong experience in C and C++, including the use of modern C++ techniques.

* Proven good working knowledge and adherence to both the Core C++ Guidelines for writing modern, maintainable C++ and the CERT Secure Coding Guidelines to mitigate critical security vulnerabilities.

* Proven ability to work with complex or long-standing codebases.

* Comfortable working across both Windows and Linux environments.

* Solid understanding of general software engineering principles and best practices.

* Experience writing effective unit tests and working with test-driven development approaches.

* Reasonable understanding of SQL and client/server architectures.

* Self-motivated and proactive, with a willingness to take initiative.

* Able to learn quickly and adapt to new tools, technologies, or environments.

Essential

Experience:

* Degree in Computer Science, Software Engineering, or a related discipline; or an industry-recognised equivalent qualification; or equivalent professional experience Including commercial experience using C/C++).

* Familiarity with legacy codebases and approaches to modernisation.

* Exposure to build systems and scripting tools such as CMake and Python.

* Understanding of system internals or compiler/interpreter concepts is an advantage.

* Strong analytical and problem-solving skills, with the ability to evaluate and balance design trade-offs effectively.

* Solid experience working in a Test Driven Development environment.

* Working knowledge of the 'Shift Left' development philosophy, integrating quality and security practices early in the software development lifecycle, and a foundational understanding of threat modelling principles, specifically using the STRIDE methodology
