Principal Engineer, AI

Description & Requirements

About the Role

Drive hands-on delivery of AI and Generative AI solutions that streamline workflows and deliver measurable business value—measured by hours saved and the breadth of users served. You will architect, develop, and maintain production-gra de systems encompassing RAG pipelines, agentic tools, model routing, vector search, evaluation, and guardrails, and o bservability—a ll tightly integrated with internal platforms and enterprise datasets.

What You Will Do

· Automate high-impact workflows for internal stakeholders, prioritizing initiatives with the greatest time savings and broadest user reach.

· Deliver production-rea dy copilots and customer-facin g applications for knowledge search, document summarization, intelligent recommendation s, conversational analytics, and end-to-end workflow automation.

· Establish operational excellence through rigorous SLAs, latency and throughput optimization, robust safety and guardrail mechanisms, transparent evaluation frameworks, and cost-efficient inference strategies.

• Architect and develop scalable, high-performan ce data and AI systems that support GenAI use cases including RAG, agentic workflows, and model orchestration.

• Own the complete solution lifecycle: problem definition → rapid prototyping → rigorous evaluation → production deployment → ongoing monitoring.

• Implement guardrails (content policies, safety filters), prompt and version management, latency and throughput tuning, cost controls, load balancing, and fallback or model-routing strategies.

• Design and implement RAG pipelines over heterogeneous and often messy datasets—inclu ding requirements documents, lessons learned, business rules, and unstructured content.

• Select appropriate embedding strategies, chunking approaches, vector search c onfigurations, rerankers, and routing policies to maximize retrieval quality.

• Develop agentic workflows leveraging LangChain, LlamaIndex, MCP, and agent-to-agent (A2A) protocols; build tooling for agentic coding use cases.

• Translate su bject-matter-e xpert knowledge into robust, maintainable prompts; evaluate trade-offs between fine-tuning and prompt engineering.

• Work hands-on with large language models, vector databases (Pinecone, FAISS), and agent memory systems.

• Containerize applications with Docker, orchestrate with Kubernetes, and automate CI/CD pipelines; manage infrastructure as code (e.g. Terraform).

• Establish observability (Datadog, Grafana, LangFuse), evaluation frameworks, and model/data governance and access controls appropriate for internal enterprise environments.

• Bring experience building and maintaining data lakes and warehouses (Snowflake, Delta Lake, BigQuery, MS Fabric).

• Build internal copilots and customer-facin g features using React, Node.js, and Python with REST or GraphQL backends.

· Collaborate closely with requirements, testing, validation, and platform teams; thrive in a fast-paced environment with clear, proactive communication and rapid iteration.

What You Need To Be Successful

• 8+ years of experience building production software, ideally including experience with ML systems, including hands-on work with LLMs and Generative AI.

• Programming: Python (FastAPI, NumPy, Pandas, scikit-learn, Pydantic, Jinja2) and Node.js; strong proficiency with APIs and distributed systems.

• LLMs & Frameworks: Hands-on experience with at least one major deep learning or LLM stack (e.g., PyTorch/Transf ormers, TensorFlow/Ker as) and orchestration frameworks such as LangChain or LlamaIndex.

• Model Providers: Working familiarity with conncting to inference providers e.g. AWS Bedrock, along with OpenAI, Anthropic, Meta/Llama, and Mistral model ecosystems.

• Data & Storage: SQL and NoSQL databases (PostgreSQL, DynamoDB), Elasticsearch for search and analytics, and vector databases (Pinecone, Weaviate, FAISS, Milvus, pgvector).

• Cloud & I nfrastructure: AWS (S3, EC2, Lambda, CloudWatch, Fargate, EKS/ECS), Azure, GCP, Databricks, Docker, Kubernetes, Terraform, CI/CD, Airflow, and Kafka.

• Operational Excellence: Load balancing, monitoring and alerting (Datadog, Grafana, LangFuse), debugging production issues, and cost/performan ce optimization.

• Soft Skills: Strong communication abilities, product-orient ed thinking, and the capacity to learn and adapt quickly in a dynamic environment.

• Education: BS, MS, or PhD in Computer Science, Electrical Engineering, Mathematics, or equivalent professional experience.
