- Implement guardrails, safe API usage, and PII protection for secure deployments.
- Monitor/evaluate agent performance with LangSmith, AgentOps, and similar tools.
- Ship real-world enterprise AI use cases - Copilots, orchestration engines, intelligent search, and more.
- Mentor and review the work of junior AI engineers, spreading best practices.
- Work with product, data, and DevOps teams to bring AI solutions into production at scale.
What Youll Bring
- Solid grounding in LLMs and GenAI (fine-tuning, prompt engineering, practical deployment).
- Proven track record with RAG pipelines and vector databases.
- Hands-on with agent frameworks (LangChain, LlamaIndex, etc.) and orchestration.
- Experience deploying/scaling models on clouds (AWS, Azure, HuggingFace).
- Strong coding ability in Python or similar.
- Familiarity with LLM Ops : monitoring, evaluation, cost optimisation.
- Delivered enterprise-grade AI solutions (not just demos).
- Experience mentoring engineers and building technical excellence in a team.
- Bonus : contributed to open-source LLM projects or worked on autonomous agent use cases (research copilots, orchestration systems).
