• Strong practical programming experience in both C++ and Python.
• A good understanding of computer architecture.
• Strong written and verbal communication skills.
• Experience building software interfaces on large-scale or complex projects.
• The ability to understand accelerator designs and how they operate.

Helpful additional experience

• Exposure to machine learning frameworks.
• Experience collaborating with architects and modelling specialists to test and validate proposed features.
• Knowledge of memory systems and memory hierarchy.
