Note: The job is a remote job and is open to candidates in USA. Amgen is a leading biotechnology company seeking a Senior Machine Learning Engineer to build and scale AI/ML platforms. This role involves designing core services, infrastructure, and governance controls for machine learning applications while collaborating with various teams to enhance the developer experience. Responsibilities • Engineer end-to-end ML pipelines—data ingestion, feature engineering, training, hyper-parameter optimization, evaluation, registration and automated promotion—using Kubeflow, SageMaker Pipelines, Open AI SDK or equivalent MLOps stacks • Harden research code into production-grade micro-services, packaging models in Docker/Kubernetes and exposing secure REST, gRPC or event-driven APIs for consumption by downstream applications • 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 • Optimize performance and cost at scale—selecting appropriate algorithms (gradient-boosted trees, transformers, time-series models, classical statistics), applying quantization/pruning, and tuning GPU/CPU auto-scaling policies to meet strict SLA targets • Instrument comprehensive observability—real-time metrics, distributed tracing, drift & bias detection and user-behavior analytics—enabling rapid diagnosis and continuous improvement of live models and applications • Embed security and responsible-AI controls (data encryption, access policies, lineage tracking, explainability and bias monitoring) in partnership with Security, Privacy and Compliance teams • Contribute reusable platform 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 • Partner with data scientists to prototype and benchmark new algorithms, offering guidance on scalability trade-offs and production-readiness while co-owning model-performance KPIs Skills • 3-5 years in AI/ML and enterprise software • Comprehensive command of machine-learning algorithms—regression, tree-based ensembles, clustering, dimensionality reduction, time-series models, deep-learning architectures (CNNs, RNNs, transformers) and modern LLM/RAG techniques—with the judgment to choose, tune and operationalize the right method for a given business problem • Proven track record selecting and integrating AI SaaS/PaaS offerings and building custom ML services at scale • Expert knowledge of GenAI tooling: vector databases, RAG pipelines, prompt-engineering DSLs and agent frameworks (e.g., LangChain, Semantic Kernel) • Proficiency in Python and Java; containerization (Docker/K8s); cloud (AWS, Azure or GCP) and modern DevOps/MLOps (GitHub Actions, Bedrock/SageMaker Pipelines) • Strong business-case skills—able to model TCO vs. NPV and present trade-offs to executives • Exceptional stakeholder management; can translate complex technical concepts into concise, outcome-oriented narratives • Master's degree with 8 + years of experience in Computer Science, IT or related field OR Bachelor's degree with 10 + years of experience in Computer Science, IT or related field • Experience in Biotechnology or pharma industry is a big plus • Published thought-leadership or conference talks on enterprise GenAI adoption • Master's degree in computer science and or Data Science • Familiarity with Agile methodologies and Scaled Agile Framework (SAFe) for project delivery • Certifications on GenAI/ML platforms (AWS AI, Azure AI Engineer, Google Cloud ML, etc.) are a plus Company Overview • Amgen is a biotechnology company that develops and manufactures human therapeutics for various illnesses and diseases. It was founded in 1980, and is headquartered in Thousand Oaks, California, USA, with a workforce of 10001+ employees. Its website is Company H1B Sponsorship • Amgen has a track record of offering H1B sponsorships, with 429 in 2025, 485 in 2024, 485 in 2023, 540 in 2022, 460 in 2021, 444 in 2020.
