CVS Scottsdael, AZ **HYBRID FROM DAY 1 About the Role We are seeking an experienced AIML Engineer to design, build, and operate AI/ML infrastructure and agentic systems. This role involves developing MCP servers and agents, integrating LLMs, and implementing RAG pipelines for production environments. Key Responsibilities · Design, build and operate MCP servers and MCP agents that host, orchestrate and monitor AI/agent workloads. · Develop agentic AI, prompt engineering patterns, LLM integrations and developer tooling for production use. · Own deployment, scaling, reliability and cost-efficiency on Kubernetes/Docker and Google Cloud with automated CI/CD · Design and implement RAG (Retrieval Augmented Generation) pipelines and integrations with vector stores and retrieval tooling; use LangChain and Langfuse for orchestration, chaining, and observability. Core Responsibilities · Implement and maintain MCP server and agent code, APIs, and SDKs for model access and agent orchestration. · Design agent behavior, workflows and safety guards for agentic AI systems. · Create, test and iterate prompt templates, evaluation harnesses and grounding/chain of thought strategies. · Integrate LLMs and model providers (self hosted and cloud APIs) with unified adapters and telemetry. · Build developer tooling: CLI, local runner, simulators, and debugging tools for agents and prompts. · Containerize services (Docker), manage orchestration (Kubernetes/GKE), and optimize nodes, autoscaling and resource requests. · Ensure observability: logging, metrics, traces, dashboards, alerting and SLOs for model infra and agents. · Create runbooks, playbooks and incident response procedures; reduce MTTR and perform postmortems. · Design and maintain RAG workflows: document chunking, embeddings, vector indexing, retrieval strategies, re ranking and context injection. · Integrate and instrument LangChain for composable chains, agents and tooling; use Langfuse (or equivalent tracing) to capture prompts, model calls, RAG traces and evaluation telemetry. Required Skills & Experience · 5+ years of Strong Software Engineering (Python/NodeJS), system design and production service experience. · 2+ years of Experience with LLMs, prompt engineering, and agent frameworks. · 2+ years of Experience Practical experience implementing RAG: embeddings, vector DBs and retrieval tuning. · 2+ years of Experience with LangChain patterns and with toolchain telemetry (Langfuse or similar) for prompt/model traceability. · 5+ years of Experience with Kubernetes, Docker, CI/CD and infrastructure as code experience. · 2+ years of Experience with Practical experience with Google Cloud Platform services · 2+ years of Experience with Observability, testing, and security best practices for distributed systems. · 2+ years of Experience with evaluating and mitigating retrieval/augmentation failures, hallucinations, and leakage risks in RAG systems. · Familiarity with vendor and open source vector stores and embedding providers. · Familiarity with CI/CD pipelines (Jenkins, GitHub Actions, GitLab CI, or ArgoCD).
