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.
• 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).
  
  

Qualifications

Tech (required) :

• 5 - 7 years of relevant experience.
• Strong knowledge of GenAI, agentic systems, and multi-agent architectures.
  
  

Attributes : clear communicator, strong leader, highly tech-savvy.
