Sr. Manager/staff Engineer, Ai Infrastructure and Operations

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 & AutomationDesign, 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 EngineeringArchitect 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 EnablementOperationalize 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 PracticesPartner 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.-
BASIC QUALIFICATIONS7+ years of hands-on software engineering experience with strong Python skills in production environments.- Proven experience designing and operating Docker-based containerized solutions and deploying them on Kubernetes.- Deep understanding of CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins, Argo Workflows, etc.) for AI/ML workflows.- Strong knowledge of Infrastructure-as-Code tools (Terraform, Pulumi, AWS CDK).- Solid understanding of distributed systems, scaling patterns, and production system reliability.- Bachelor’s or Master’s degree in Computer Science, Engineering, or related field.

PREFERRED QUALIFICATIONSExpertise in AWS cloud services (EC2, S3, Lambda, EKS, SageMaker, API Gateway, CloudFormation, IAM, etc.).- Experience building and deploying microservices and REST/gRPC APIs for AI model delivery.- Familiarity with Mlflow, Kubeflow or other MLOps orchestration platforms is a strong plus.- Proficiency with model serving frameworks (TensorFlow Serving, TorchServe, KServe, Seldon Core, BentoML, etc.).
