Years of Experience: 10-15 Years Rate: $80/Hr on W2 CR Internal Project Keywords search (share years of experience with below in skill matrix) Lang Chain, Lang Graph, RAG AWS (Bedrock, sage Maker, Lambda, EKS/ECS) MLflow, Docker Job Overview: We're seeking a ML Engineer / Data Scientist to architect agentic AI solutions and own the full ML lifecycle-from proof-of-concept to production. You'll operationalize LLMs, build agentic workflows, implement MLOps best practices, and design multi-agent systems for cybersecurity tasks. Key Responsibilities: • Operationalize large language models and agentic workflows (LangChain, LangGraph, LlamaIndex) to automate security decision-making and threat response. • Design, deploy, and maintain multi-agent AI systems for log analysis, anomaly detection, and incident response. • Build proof-of-concept GenAI solutions and evolve them into production-ready components on AWS (Bedrock, SageMaker, Lambda, EKS/ECS) using reusable best practices. • Implement CI/CD pipelines for model training, validation, and deployment with GitHub Actions, Jenkins, and AWS CodePipeline. • Manage model versioning with MLflow and DVC, set up automated testing, rollback procedures, and retraining workflows. • Automate cloud infrastructure provisioning with Terraform and develop REST APIs and microservices containerized with Docker and Kubernetes. • Monitor models and infrastructure through CloudWatch, Prometheus, and Grafana; analyze performance and optimize for cost and SLA compliance. • Collaborate with data scientists, application developers, and security analysts to integrate agentic AI into existing security workflows. Qualifications: • Bachelor's or Master's in Computer Science, Data Science, AI or related quantitative discipline. • 4+ years of software development experience, including 3+ years building and deploying LLM-based/agentic AI architectures. • In-depth knowledge of generative AI fundamentals (LLMs, embeddings, vector databases, prompt engineering, RAG). • Hands-on experience with LangChain, LangGraph, LlamaIndex, Crew.AI or equivalent agentic frameworks. • Strong proficiency in Python and production-grade coding for data pipelines and AI workflows. • Deep MLOps knowledge: CI/CD for ML, model monitoring, automated retraining, and production-quality best practices. • Extensive AWS experience with Bedrock, Sage Maker, Lambda, EKS/ECS, S3 (Athena, Glue, Snowflake preferred). • Infrastructure as Code skills with Terraform. • Experience building REST APIs, Microservices, and containerization with Docker and Kubernetes. • Solid data science fundamentals: feature engineering, model evaluation, data ingestion. • Understanding of cybersecurity principles, SIEM data, and incident response. • Excellent communication skills for both technical and non-technical audiences. Preferred Qualifications: • AWS certifications (Solutions Architect, Developer Associate). • Nice to have Experience with Model Context Protocol (MCP) and RAG integrations. • Nice to have Experience in Crew.AI • Familiarity with workflow orchestration tools (Apache Airflow). • Experience with time series analysis, anomaly detection, and machine learning.
