Job DescriptionThe Sr. ML Engineer is responsible for designing, building, and managing the scalable cloud infrastructure that powers our AI and Machine Learning applications. Rather than focusing primarily on model building, this role is suited for a specialist with deep expertise in MLOps, AWS cloud architecture, Kubernetes, and system design. You will own key modules of the ML platform, perform architectural reviews, and implement robust deployment standards. The team is tasked with building secure, scalable pipelines and serving infrastructure for both traditional ML and modern Generative AI (LLM) workloads. The successful candidate will act as a design authority for model deployment, infrastructure automation, and platform security, shaping best practices to enable our data scientists and AI engineers to seamlessly transition models from research to production.
All roles require digital fluency, including the ability to work with emerging technologies and AI-assisted tools - such as AI coding assistants (e.g., GitHub Copilot, ChatGPT, Claude Code, CLine), advanced reasoning GenAI models, and enterprise productivity tools - to enhance engineering productivity and support everyday work.
Key Responsibilities:
- ML Platform Architecture: Design, build, and maintain scalable, highly available Machine Learning infrastructure on AWS and Visa OnPrem.
- Kubernetes & Kubeflow Management: Deploy, configure, and manage Kubernetes clusters and Kubeflow to orchestrate complex ML training and deployment pipelines.
- Model Deployment & LLMOps: Build robust serving infrastructure to productionize machine learning models and Large Language Models (LLMs) using modern serving frameworks (e.g., vLLM, TensorRT-LLM, KServe, Triton).
- Cloud Security & Access Management: Design secure platform architectures utilizing AWS IAM (roles, policies, least privilege), VPCs, and security groups to ensure data and model security.
- System Design & Infrastructure as Code (IaC): Architect scalable cloud systems and automate infrastructure provisioning using tools like Terraform or AWS CloudFormation.
- CI/CD & MLOps: Develop and maintain automated CI/CD pipelines for model training, testing, and deployment, ensuring seamless continuous integration.
- Cross-Functional Enablement: Partner closely with Data Scientists and AI Engineers to understand their compute and tooling needs, reducing friction in the model development lifecycle.
- Observability & Monitoring: Implement logging, monitoring, and alerting for ML models and underlying infrastructure (e.g., CloudWatch, Prometheus, Grafana) to track system health, model drift, and latency.
- Modernization: Act as a technical guide to modernize legacy deployment pipelines and integrate emerging AI infrastructure technologies.
This is a hybrid position. Expectation of days in office will be confirmed by your hiring manager.
