Integrate pre-trained models, LLM APIs, and tool-calling integrations into analytics products
Refactor notebooks and prototypes into production components with error handling, guardrails, and logging
Build and maintain data pipelines that prepare datasets for agents to reason over
Diagnose failures and quality drift in owned agents and update context, prompts, and logic
Evaluate own work with validation sampling, source traceability, and version documentation
Integrate pre-trained models, LLM APIs, and tool-calling and MCP-style integrations into the team’s analytics products
Take an experimental notebook or a prototype and refactor it into a production-ready component with the error handling, guardrails, telemetry, and logging the team can rely on.
Prepare, clean, and structure the datasets your agents reason over, and build and maintain the pipelines that feed them.
Diagnose failure and quality drift in the agents you own, conduct root cause analysis on moderately complex issues, and update context, prompts, and logic as data or business rules change.
Apply the team’s evaluation standard and definition of done: validation sampling, source traceability, prompt and model version documentation, and testing suited to non-deterministic model behavior.
Bachelor’s degree in Computer Science, Data Science, or a related field.
3+ years in software engineering, data engineering, data science, or analytics, with hands-on exposure to building or contributing to LLM-based agents or AI-native systems.
Proficiency in Python and strong SQL, with a solid grounding in programming concepts, design patterns, SDLC principles, and unit testing.
Experience refactoring experimental or research code into production-ready components following established patterns.
Familiarity with MLOps and LLMOps practices and the lifecycle of AI-powered software, including testing, evaluation, and monitoring.
Product sense: an instinct for what a product manager will act on, and the judgment to tell a metric that changes a decision from one that only fills a dashboard. Experience in or alongside product teams, and SaaS experience, are assets.
Hands-on experience integrating LLM APIs (e.g. Anthropic, OpenAI) into applications, including prompt and response handling and cost and safety considerations.
Experience with a modern data stack (e.g. Snowflake, Databricks)

We file this job under ML Engineer, by the work the posting describes.
ML engineers put machine learning models into products. They write the code that trains, ships, serves and monitors models so a recommendation or prediction works for real users.
Postings ask for strong Python and software engineering, a framework such as PyTorch, cloud services, and more and more often experience with large language models.
A data scientist often works out which model to build; an ML engineer makes it run reliably in production.
The government has no code for ML engineers, so these figures are for the closest group, computer and information research scientists.
