The Role
As a Senior AI Engineer, youll own the full lifecycle of AI solutions - from design to production.Youll be hands-on with multi-agent workflows, advanced knowledge retrieval, and LLM optimization to solve enterprise-scale problems.Expect to lead projects such as AI Copilots, Enterprise Search Systems, Summarization Engines, and Intelligent Automation Tools - building robust, scalable solutions that move beyond prototypes into production.Youll also play a key role in mentoring junior engineers, setting engineering standards, and collaborating cross-functionally to ensure delivery at scale.
What Youll Do
- Build and deploy agentic systems and multi-agent workflows using LangChain, LlamaIndex, OpenAI SDK (and beyond).
- Design RAG pipelines with vector DBs like FAISS, Pinecone, Weaviate, or Qdrant.
- Fine-tune and optimize LLMs (GPT-4, Claude, LLaMA, Mistral, Gemini) with LoRA/QLoRA, quantization, and other techniques.
- 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.
