About the Job

Requirements

  • A bachelor's degree or four or more years of work experience is required.
  • Six or more years of relevant experience is required, demonstrated through work and/or military experience or specialized training.
  • Six or more years building production software or models, including experience deploying large language model applications, agentic workflows, or tool-calling pipelines.
  • Hands-on experience using frontier large language models such as Anthropic Claude, OpenAI, or Google Gemini, and agentic coding tools such as Claude Code, Cursor, or Copilot to deliver solutions with measurable business outcomes.
  • A strong foundation in statistics and machine learning applied to forecasting, prioritization, or optimization.
  • Experience designing offline and online evaluation harnesses, guardrail frameworks, and observability systems for latency, token costs, hallucination tracking, and tracing.
  • Advanced proficiency in Python and SQL, plus working proficiency in TypeScript/Node.js for API integration and backend orchestration.
  • Experience designing APIs and deploying containerized services with Docker and data workflows on platforms such as Apache Airflow, Kubernetes (EKS/GKE), and Domino Data Lab, across AWS, GCP, or Azure.
  • Ability to independently scope ambiguous initiatives, translate business requirements into technical architectures, lead delivery end-to-end, and present designs to senior executives.

Responsibilities

  • Research and apply advances in statistics, machine learning, and artificial intelligence to capital-planning problems such as demand forecasting, solution prioritization, optimization, and impact measurement, and build the results into production models.
  • Define full-stack architecture for embedded AI initiatives, including multi-agent orchestration, state machines, latency and cost budgets, security boundaries, and enterprise backend integrations.
  • Architect stateful agent workflows that comply with agentic governance rules, using LangGraph, Temporal, or event-driven state machines, and establish protocols for tool calling, execution sandboxing, and deterministic fallback logic.
  • Design production retrieval-augmented generation infrastructure incorporating hybrid search, re-ranking algorithms, metadata filtering, and semantic caching, and apply it to extract signal from unstructured engineering and project documents.
  • Deploy production agent services and scheduled workflows to target runtimes, including Domino Data Lab, Apache Airflow, Kubernetes microservices, and serverless compute across AWS, GCP, or Azure.
  • Architect offline and online evaluation frameworks, including LLM-as-a-judge, synthetic test generation, backtesting against actuals, human-in-the-loop review queues, and live A/B rollouts, to measure model drift, context hallucination rates, and task-completion metrics and keep AI-assisted capital recommendations explainable and traceable.
  • Generalize custom domain deployments into reusable internal SDKs, API primitives, modular UI components, and standardized modeling procedures; mentor engineers across the organization; and lead invention disclosures and patent filings.
  • Embed alongside business-unit leadership to map operational processes and identify high-leverage intervention points where applied AI can deliver measurable improvement.
  • Serve as the technical authority with business-unit vice presidents and managing directors, explaining algorithmic behavior, failure modes, and performance trade-offs.

Desired Qualifications

  • Experience building and scaling centralized context platforms or enterprise search engines.
  • Experience designing production retrieval-augmented generation pipelines, vector databases such as pgvector, Milvus, or Pinecone, hybrid dense and sparse/lexical search, and dynamic context management.
  • Experience in time-series forecasting, mathematical optimization, or causal inference.
  • Experience with model risk management, explainability, or validation of models used in high-stakes decisions.
  • Prior forward-deployed engineering, solutions architecture, or technical consulting experience in top-tier technology firms or hyperscalers.
  • A track record of turning one-off operational builds into enterprise-wide shared libraries, with associated technical publications or filed patents.
  • Domain knowledge in telecommunications, network capacity optimization, capital planning, or large-scale customer-care operations.
