• Follow agreed design and coding standards within an iterative development environment.

Skills and experience

• Strong C++ or relevant object-oriented software development experience.

• Familiarity with electronics, lower-level firmware and hardware interfacing.

• Experience developing test frameworks and automated tests.

• Experience creating or interpreting technical interface documentation.

• Knowledge of microservices and containerisation.

• Experience developing HMI or GUI applications, with an understanding of user experience.

• Experience developing applications for Windows and Linux.

• Familiarity with Agile or other iterative development approaches.

• Experience using tools such as Jira, Azure DevOps and Git.

• Strong communication skills and the ability to work collaboratively across engineering disciplines.

Useful additional experience

• Python, C# or LabVIEW.

• CUDA integration for AI or machine learning applications.

• Industrial communication protocols.

• Infrared technologies.

• A relevant qualification in software engineering, computer science, physics or a related discipline.
