Data Scientist - Agentic AI

Data Scientist - Agentic AIThis role has been designed as 'Hybrid' with a requirement that you will work on average 2 days per week from an HPE office.

Job Description:

The Data Scientist – Agentic AI builds and operationalizes the core agentic workflows that power Marvis, Juniper's next-generation AI assistant for network operations. Working at the intersection of data science, generative AI, and production engineering, this role is responsible for designing, implementing, and evaluating the reasoning pipelines, tool-calling patterns, skills, and MCP server integrations that enable Marvis to autonomously diagnose, troubleshoot, and resolve complex networking problems. The ideal candidate combines practical experience with LLM-based agentic frameworks (LangGraph preferred) with the software engineering discipline needed to deliver reliable, observable AI systems in a cloud-native environment

Management Level Definition:

Contributions impact technical components of products, solutions, or services regularly and sustainably. Applies advanced subject matter knowledge to solve complex business and technical problems and is regarded as a subject matter expert in agentic AI and applied GenAI. Provides expertise and partnership to functional and technical project teams and may participate in cross-functional initiatives. Exercises significant independent judgment to determine best method for achieving objectives. May lead projects and mentor colleagues.

Responsibilities:

• Design, implement, and iterate on agentic workflows using LangGraph, including ReACT orchestration loops, dynamic tool selection and binding, multi-step reasoning, and self-correction patterns.
• Develop and maintain MCP (Model Context Protocol) servers and skills — defining tool schemas, implementing domain-specific tools, writing skill playbooks (SKILL.md), and managing server lifecycle (versioning, deployment, monitoring).
• Integrate and optimize LLM capabilities at production scale, including structured outputs, streaming, function/tool calling, prompt engineering, and robust error handling across agent execution paths.
• Build and refine retrieval and memory services for agentic systems, including RAG pipelines, vector-store-backed semantic search, hybrid retrieval, long-term agent memory (semantic, episodic, procedural), and relevance tuning.
• Design and execute evaluation frameworks for non-deterministic agentic systems — defining metrics, building test harnesses, running A/B tests on skills and tool configurations, and driving continuous quality improvement.
• Collaborate with domain experts (network engineers, product managers) to formalize networking problems as agentic workflows, translating troubleshooting playbooks into skills, tools, and data pipelines.
• Develop data analysis and transformation logic that runs in sandboxed execution environments (Code Mode), including multi-tool orchestration scripts, data aggregation, and visualization.
• Deploy and operate containerized services in Kubernetes, contributing to CI/CD pipelines, container image management, health probes, and resource optimization.
• Own observability for agentic workflows — implementing tracing, logging, cost tracking, and performance monitoring to ensure reliability of non-deterministic systems in production.

Education and Experience Required:

• Bachelor’s, Master's or PhD degree in computer science, data science, mathematics, statistics, or a closely related quantitative discipline. degree in computer science, engineering, information systems, or closely related quantitative discipline.
• Typically, 4-7 years of experience building production ML/AI systems, with at least a year of hands-on work with generative AI and LLM-based applications

Knowledge and Skills:

Agentic AI & GenAI (Required):

• Production experience with agentic orchestration frameworks: LangGraph (strongly preferred), LangChain, Claude Agent SDK, or equivalent — beyond prototypes.
• Solid understanding of agentic design patterns: ReACT loops, tool/function calling, dynamic tool binding, skill-based execution, multi-step planning, and self-correction.
• Hands-on experience with MCP (Model Context Protocol) or equivalent tool-serving protocols: tool schema design, server implementation, registry management.
• LLM API integration at scale: prompt engineering, structured outputs, streaming, error handling, and cost optimization.RAG pipeline design: chunking strategies, re-ranking, hybrid search, vector stores (OpenSearch or equivalent), and relevance optimization.
• Experience building evaluation and testing frameworks for non-deterministic AI systems (offline evals, A/B testing, LLM-as-judge).

Data Science & ML (Required):

• Strong foundation in statistical and machine learning techniques — anomaly detection, time-series analysis, clustering, causal inference, or related methods.
• Applied ML intuition: knowing when to use retrieval vs. fine-tuning, prompt engineering vs. structured generation, and how to debug model behavior in production.
• Proficient Python developer with experience in production codebases (not just notebooks).

Infrastructure & Production Systems (Required):

• Kubernetes: deploying, scaling, and managing workloads (Deployments, Services, ConfigMaps, Secrets, health probes).
• CI/CD pipelines for automated build, test, and deploy (Jenkins, GitHub Actions, ArgoCD, or similar).
• Container image management: building, tagging, versioning via Docker; familiarity with a container registry (ECR, GCR).
• Backend service development: FastAPI or equivalent; REST/GraphQL API design.
• Observability for AI systems: experience with tracing, monitoring, and logging tools (LangFuse, Prometheus, or equivalent)..

Additional Preferred Skills:

• Experience with agent memory systems (e.g., LangMem, custom memory architectures).
• Familiarity with sandboxed code execution environments (E2B, Firecracker, or similar).
• Networking domain knowledge (wireless/wired diagnostics, network troubleshooting) is preferred but not required.
• Experience with AWS Bedrock, OpenSearch Serverless, or similar managed AI/ML services.
• Great written and verbal communication skills; ability to articulate technical designs to senior leadership
