About the Role

We're looking for a Senior AI Engineer with a strong data science foundation who has made the transition into building production GenAI and agentic systems. You'll lead the design and delivery of LLM-powered applications end to end — from problem framing through deployment — and serve as a technical anchor for the team. This is a hands-on senior role with significant influence over architecture, standards, and how we apply AI to real business problems.

Experience: 8–12 years, including demonstrable hands-on experience shipping GenAI/agentic applications to production.

What You'll Do

• Design and build end-to-end GenAI applications: RAG systems, agentic workflows, tool-using assistants, and multi-agent orchestration.
  
• Own architecture decisions across model selection, retrieval design, orchestration, and serving — balancing cost, latency, and quality.
  
• Establish evaluation frameworks, observability, and guardrails to make AI systems reliable and safe in production.
  
• Partner with product and business stakeholders to translate ambiguous problems into scoped, high-ROI AI solutions, and to judge when GenAI is (and isn't) the right tool.
  
• Set technical standards, review designs and code, and mentor mid-level data scientists and engineers.
  
• Stay current with a fast-moving field and bring well-filtered, practical recommendations to the team.
  

Required Qualifications

• 8–12 years in data science / ML, with a track record of production-deployed models and systems.
  
• Strong foundations in ML and statistics: supervised/unsupervised learning, experimentation and A/B testing, model evaluation; familiarity with causal inference and time series.
  
• Expert Python (pandas, NumPy, scikit-learn), strong SQL, and proficiency in PyTorch or an equivalent DL framework.
  
• Demonstrated experience building GenAI applications: prompt engineering, RAG (chunking, embeddings, vector databases, reranking), and fine-tuning/adaptation (SFT, LoRA/PEFT) with sound judgment on when to use each.
  
• Hands-on experience designing agentic systems: tool/function calling, planning and orchestration, memory and state management, using frameworks such as LangChain/LangGraph, LlamaIndex, CrewAI, or AutoGen (and knowing when to build directly).
  
• Experience with LLM evaluation and observability (e.g., LLM-as-judge, golden datasets, tracing tools like LangSmith/Langfuse/Arize) and with guardrails for hallucination, safety, and prompt-injection defense.
  
• Production engineering skills: API design, serving and streaming, caching/batching, rate-limit handling, Docker, and CI/CD.
  
• Strong communication skills and experience mentoring or leading technically.
  

Preferred Qualifications

• Inference optimization experience (quantization, vLLM/TGI, GPU serving) and cost optimization at scale.
  
• Familiarity with MCP and emerging model-to-system interoperability standards.
  
• Kubernetes and infrastructure-as-code (Terraform).
  
• Experience with multimodal or unstructured data pipelines.
