About the role

ROLE SUMMARY 

 

The Senior Manager/Staff Engineer, AI Infrastructure & MLOps Engineering is a senior individual contributor position reporting directly to the Director, AI Infrastructure and Operations Lead. This role is highly technical, hands-on, and focused on building the core automation, tooling, and infrastructure that power the internal AI platform and services. 

 In this position, the Senior Manager/Staff Engineer is responsible for designing and implementing systems that enable scientists and engineers to rapidly build, deploy, and monitor machine learning models in production. Work will span Python-based automation, containerization with Docker, CI/CD pipelines, AWS cloud infrastructure, microservices, and high-performance model serving frameworks. 

 The role plays a critical part in advancing the organization’s MLOps capabilities by creating reusable components and internal developer platforms that increase velocity, reliability, and scalability of AI/ML delivery. 

 

ROLE RESPONSIBILITIES  

 

Core Engineering & Automation 

 

  • Design, build, and maintain Python-based tooling, SDKs, and automation frameworks to support model development, deployment, and monitoring workflows. 

  • Develop containerized solutions using Docker and orchestrate them using Kubernetes (including Kubeflow or similar MLOps platforms). 

  • Build and maintain CI/CD pipelines to streamline ML model integration, testing, and deployment into production environments. 

  • Implement robust automation for provisioning, configuring, and managing cloud resources using Infrastructure-as-Code (Terraform, Pulumi, AWS CDK, etc.). 

 

Cloud Infrastructure & Platform Engineering 

 

  • Architect and manage scalable, secure, and high-availability AWS infrastructure to support AI workloads. 

  • Develop and optimize microservices architectures for AI/ML serving, ensuring high throughput and low latency. 

  • Build and maintain APIs and services for model management, feature stores, and inference pipelines. 

  • Implement monitoring, logging, and observability tools to ensure performance, availability, and reliability of AI services. 

 

Model Serving & MLOps Enablement 

 

  • Operationalize ML model serving at scale using frameworks such as TensorFlow Serving, TorchServe, KServe, Seldon Core, or custom inference services. 

  • Create reusable MLOps components for data preprocessing, training orchestration, model validation, and deployment. 

  • Develop automation to reduce ML model deployment time, enforce versioning, and enable rollback/upgrade capabilities. 

  • Work closely with data scientists to translate research workflows into production-grade, scalable services. 

 

Collaboration & Best Practices 

 

  • Partner with AI researchers, data engineers, and platform engineers to deliver integrated solutions. 

  • Champion engineering excellence by promoting design documentation, code reviews, CI/CD best practices, and testing automation. 

  • Contribute to a culture of shared ownership, transparency, and internal open-source development.
