Principal AI Engineer

with

deep, handson experience in Large Language Models (LLMs)

to lead the design, development, and deployment of

enterprisegrade AIpowered automation systems

across the organization. This role goes beyond experimentation. You will

own and deliver productionscale AI solutions , analyze complex internal workflows, identify highvalue automation opportunities, and architect intelligent systems that materially improve efficiency, accuracy, and scalability.

This position is ideal for a

seasoned engineer (10+ years)

who combines

strong technical depth, architectural judgment, and a product mindset , and who enjoys building

practical, highimpact AI systems used at scale . KEY RESPONSIBILITIES: Lead the

design, development, and deployment

of LLMbased automation solutions across multiple business functions. Work closely with crossfunctional teams to

define problem statements, data requirements, system boundaries, and solution approaches . Architect and implement

endtoend LLM systems , including:

Prompt pipelines Agentbased architectures RetrievalAugmented Generation (RAG) systems Internal AI services and APIs

Integrate commercial and opensource LLMs (e.g., OpenAI, Anthropic, Databricks, opensource models) into

enterprise systems and products . Drive

model evaluation, prompt optimization, and system reliability improvements

based on realworld usage. Establish and maintain

monitoring, logging, and evaluation frameworks

for LLMdriven applications. Partner with product, operations, security, and engineering teams to

map workflows and identify highROI automation opportunities . Ensure all AI solutions meet

enterprise standards for data privacy, security, compliance, and governance . Act as a

technical mentor and thought leader , setting best practices for LLM engineering and applied AI. Stay current with advances in LLMs, agent frameworks, AI infrastructure, and applied research-and translate them into pragmatic solutions.
