• Leverage AI code generation tools to accelerate C++ development, then validate output against hardware specs and safety requirements 

• Design and implement network protocols purpose-built for transit applications 

• Work across Intel and ARM architecture environments using PCIe, USB, SATA, I²C, SPI, and other standard interfaces 

• Use AI-assisted tools to generate unit test scaffolding and boilerplate, then review and extend coverage for edge cases 

• Draft technical documentation and inline comments with AI assistance, then refine for accuracy and compliance 

• Build systems with attention to power management, standalone operation, aperiodic communications, and data security 

•  Use AI tools to research and summarize protocol options and vendor documentation during design phases 

• Participate in hardware and software design reviews and support product testing and validation

• Ability to critically review AI-generated code — you catch hallucinations, hardware mismatches, and unsafe assumptions 

• Familiarity with Linux application and middleware development 

• Experience writing automated unit tests — including AI-scaffolded tests you've validated and extended 

• Familiarity with prompt engineering or structured AI workflows in a technical context preferred 

Education and Experience:  

• 2+ years of hands-on embedded software development in C++ 

• Minimum of 1 year of experience with Windows Script or PowerShell
