Let’s do this. Let’s change the world. In this vital role you will Own enterprise AI/ML architecture, standards, APIs, and guardrails across cloud/on-prem.

We are seeking a Principal Machine Learning Engineer —Amgen’s most senior individual-contributor authority on building and scaling end-to-end machine-learning and generative-AI solutions. Sitting at the intersection of engineering excellence and data-science enablement, you will develop, deploy and monitor models—classical ML, deep learning and LLMs—securely and cost-effectively. Acting as a “player-coach,” you will establish AI solution strategy, define technical standards, and partner with DevOps, Security, Compliance and Product teams to deliver a frictionless, enterprise-grade AI solutions.

Roles & Responsibilities:

• Own enterprise AI/ML architecture, standards, APIs, and guardrails across cloud/on-prem.

• Build production ML/GenAI solutions and lightweight apps delivering sub-second insights.

• Build end-to-end ML pipelines —data ingestion, feature engineering, training, hyper-parameter optimisation, evaluation, registration and automated promotion—using Kubeflow, SageMaker Pipelines, Open AI SDK or equivalent MLOps stacks.

• Build and maintain full-stack AI applications by integrating model services with lightweight UI components, workflow engines or business-logic layers so insights reach users with sub-second latency.

• Establish observability, SLOs, and safe deploys (blue-green/canary, shadow, rollbacks) with incident runbooks.

• Lead rigorous evaluation (offline/online, A/B), drift detection, and automated retraining.

• Architect LLM/RAG with prompt management, safety guardrails, and optimized inference.

• Enforce data quality , lineage, and model/data cards; apply privacy-preserving techniques where needed.

• Contribute reusable ML/GenAI components —feature stores, model registries, experiment-tracking libraries—and evangelize best practices that raise engineering velocity across squads.

• Perform exploratory data analysis and feature ideation on complex, high-dimensional datasets to inform algorithm selection and ensure model robustness.

• Prototype and benchmark new algorithms , offering guidance on scalability trade-offs and production-readiness while co-owning model-performance KPIs.

• Translate domain needs (R&D, Manufacturing, Commercial) into roadmaps; mentor teams and communicate trade-offs.
