About the Job

Requirements

  • Senior-level experience in machine learning engineering, with a strong focus on productionizing infrastructure.
  • Ability to use managed solutions such as Vertex AI while investigating distributed architectures, developing custom connectors, and working around framework limitations.
  • Demonstrated ability to work in changing technical environments.
  • Operational proficiency with Google Cloud Platform and understanding of containerized environments such as Docker and Kubernetes.
  • Production-oriented Python backend development; operational mastery of containerization, CI/CD, automated testing, observability, and log management.
  • Experience with deployment platforms such as Vertex AI Agent Builder and Gemini Enterprise Agent Platform, and integration protocols such as the Model Context Protocol.
  • Experience optimizing context windows for large frontier models and routing requests to suitable models.
  • Ability to build LLM testing frameworks, including LLM-as-a-Judge and Golden Datasets, and use deterministic metrics and strict output-format validation such as JSON schema enforcement.
  • Practical experience with Agentic RAG, semantic caching, or prompt-optimization frameworks such as DSPy.
  • Applied experience in supply chain, retail, or model deployment using Databricks or MLflow.
  • Ability to define relevant data evaluation metrics aligned with functional requirements.
  • Strong communication and collaboration skills; ability to work effectively in a fast-paced environment; problem-solving ability and attention to detail; adaptability and willingness to learn and share new technologies and methodologies; ability to explain complex technical concepts to nontechnical stakeholders and understand user needs.

Responsibilities

  • Design and deploy the foundations that allow AI agents to be hosted, run, and interact smoothly with systems in production.
  • Design robust pipelines for asynchronous, multistep agent execution, including transactional ingestion and writing flows, and implement distributed resilience patterns.
  • Integrate agent orchestration SDKs, especially Google Vertex AI Agent SDK / ADK, while addressing limitations of managed frameworks.
  • Orchestrate production agents efficiently, manage information processing and routing to suitable models, optimize costs and token usage, and ensure task quality and execution speed.
  • Strictly define each agent’s scope of action so agents access only formally authorized data and actions while respecting privacy rules and securing data.
  • Build advanced performance measurement and tracking pipelines to trace agent reasoning and decisions end to end and debug production logic.
  • Work with the team to define relevant data-evaluation metrics consistent with defined functional requirements.
  • Collaborate closely with digital, data, product, and engineering teams to architect deployment infrastructure, design intelligence routing, and build secure infrastructure for agents to interact with enterprise data and legacy systems.
