You will join our Machine Learning Engineering team to build the next generation of AI products at Capital Group – including agentic systems, LLM‑powered workflows, and the platform that ensures they are safe, governed, and reliable in production.

You will operate at the intersection of production ML, GenAI and agentic workflows, and governed data infrastructure. In this high‑impact role, you will help define how enterprise‑grade AI systems are designed, deployed, and operated. You will work with a high degree of autonomy, mentor junior engineers, and drive engineering standards across projects built on Databricks, AWS, and agent‑based architectures.

• You architect and operate end‑to‑end production AI systems – designing, building, deploying, monitoring, and managing the full lifecycle of ML and GenAI workloads
• You develop production‑grade cloud‑native environments optimized for AI/ML model training, serving, and orchestration
• You establish and evangelize engineering standards, reference patterns, and reusable platform components for AI services across the firm
• You design scalable inference pipelines, including retraining loops, drift detection, evaluation harnesses, and observability

• You build agentic systems with multi‑step reasoning, orchestration, and tool/function calling, including MCP‑based integrations
• You develop evaluation harnesses, traces, and replay tooling so agent behavior is observable and continuously improvable
• You apply advanced prompt engineering, evaluation frameworks, guardrails, and human‑in‑the‑loop patterns to deliver reliable LLM‑powered features
• You drive the agentic SDLC, defining how agents are designed, tested, evaluated, deployed, and monitored as first‑class production assets

• You build solutions on Databricks (Unity Catalog, MLflow, Spark) and AWS, leveraging native AI capabilities for model training, serving, and governance
• You use Infrastructure as Code to provision and manage cloud‑native, scalable, and secure environments
• You integrate with vector stores, graph databases, Redis, Dynamo
  
  DB, and Elasti Cache to enable retrieval, memory, and state for AI applications

• You build REST and streaming APIs to expose ML and agentic capabilities to downstream products and platforms
• You apply advanced prompt…
