• Hands‑on experience with machine learning or LLM‑based systems.
• Experience fine‑tuning, adapting, or evaluating AI models.
• Ability to build full AI applications, prototypes, or production components.
• Familiarity with modern AI development tools and coding assistants.
• Strong problem‑solving skills and ability to work independently in a startup environment.

Preferred Qualifications

• Experience with agentic AI systems, tool‑calling, workflow orchestration, or multi‑step AI applications.
• Experience with AI safety, alignment, guardrails, red teaming, or model monitoring.
• Familiarity with LangChain, LlamaIndex, Hugging Face, PyTorch, TensorFlow, OpenAI APIs, or Anthropic APIs.
• Experience with RAG systems, embeddings, vector databases, or enterprise AI deployment.
• Background in applied research, enterprise software, cybersecurity, or AI governance.
