- Proficiency in Python for model development and implementation.
- Familiarity with LLM-based applications, including embeddings and advanced AI use cases.
- Strong communication skills, able to clearly explain technical concepts to both technical and non-technical stakeholders.
- Experience working effectively with distributed teams across time zones.
