Required Skills:

• System level performance analysis and strong OS fundamentals (memory management, multithreading/synchronisation, user/kernel mode interaction) and Virtual Machines.
• Understanding of ARM CPU architectures.
• Expert proficiency in Python and Rust programming languages.
• Solid understanding of machine learning and deep learning fundamentals, including various architectures, and evaluation metrics.
• Strong analytical and problem‑solving skills, with the ability to design and conduct rigorous experiments.
• Excellent communication and team work skills, with a results‑orientated attitude
• Proficiency in problem solving and debugging.

Desirable Skills:

• Expert proficiency in C and C++ programming languages
• Experience working with ARM 64-bit architecture.
• Familiarity with CPU hardware architectures.
• Experience with trusted execution environments, specifically confidential computing.
• Previous hands‑on experience with deep learning model optimization: quantization, pruning, distillation, or operator‑level optimizations.
• Experience with deploying AI models on-device (mobile, embedded, XR, edge accelerators, etc.).
• Familiarity with on-device / lightweight inference runtimes such as: ExecuTorch, llama.cpp, or Candle (or similar libraries).
