• Developing applications using C, C++, Java or C#.
• Creating automation and tooling using Python, Bash, PowerShell or similar scripting languages.
• Working within Linux, Windows or Android environments.
• Designing, developing and maintaining secure, well-tested software using modern engineering practices.
• Building automated testing, Continuous Integration and Continuous Deployment (CI/CD) pipelines.
• Understanding low-level system architecture, operating systems or processor architectures including x86/x64 and ARM.

Desirable Experience

Experience in any of the following would be advantageous:

• Ghidra, IDA Pro or other reverse engineering tools.
• Cloud technologies, particularly AWS.
• Containerisation, virtualisation or emulation platforms.
• Artificial Intelligence or Machine Learning.
• Embedded software or firmware development.
