Data Scientist IV

• Design, build, and maintain AI agents using code-based frameworks such as LangGraph with explicit control of state, control flow, tool integration, and prompts.
• Enhance and maintain multiple agents including Structured Investigation, recommendation, Data Lake Exploration, and conversational agents for Network Engineering and NSOC.
• Integrate agents with anomaly detection outputs, the IIA Data Lake, and real-time sources via MCP servers.
• Deploy agents to production through CI/CD pipelines, coordinating containerization and gateway integration.
• Design and execute supervised evaluations by building gold standard datasets with network SMEs and measuring agent correctness.
• Instrument and analyze agent behavior using tracing and observability tools such as LangSmith to diagnose failures and improve quality.
• Apply prompt and context engineering to improve reasoning, accuracy, and reliability.
• Ensure production standards including version control, automated testing, and deterministic, reviewable control flow.
• Collaborate with Data Engineering, Anomaly Detection, and Platform Engineering on data access, workflows, and infrastructure.
• Support autonomous remediation use cases in partnership with Network Engineering and NSOC.
• Document designs, evaluation methods, and results for varied technical audiences.
• Continuously evaluate frameworks, evaluation approaches, and tooling.

• Strong communication and collaboration skills.
• Strong software engineering fundamentals with object-oriented programming. Python preferred; Scala or Java acceptable.
• Hands-on experience with distributed computing frameworks such as Spark.
• Proven experience building AI agents programmatically using frameworks such as LangGraph or equivalent. No-code or low-code experience alone is not sufficient.
• Understanding of LLMs and agentic patterns including multi-step reasoning, tool calling, retrieval, memory, and orchestration.
• Experience with prompt and context engineering.
• Demonstrated evaluation of model or agent quality including dataset design and correctness criteria beyond automated LLM-as-a-judge.
• Production deployment experience with version control, automated testing, and reproducible behavior.
• Experience with AWS services such as S3 and Athena and working with data at scale.
• Strong SQL and structured data skills.
• Experience with Git-based workflows.
• Preferred: experience with LangSmith for evaluation and tracing, MCP server integrations, CI/CD deployments, LLM-as-a-judge metrics, telecom or large-scale network operations, network data sources, n8n or similar orchestration, REST APIs, cloud SDKs such as boto3, and modular code practices.

Education Requirements:

• Bachelor’s degree in Computer Science, Mathematics, Statistics, Engineering, or related field, or equivalent experience.
• Related experience: 5+ years with a bachelor’s degree, or 3+ years with a master’s degree in data science, machine learning, or agent/software development.
