• Own the deployment and life cycle management of dedicated data environments (e.g., development, staging, production) to ensure separation, security, and scalability for our Data Engineering teams
• Architect and configure high-throughput, low-latency networking (VPC peering, PrivateLink, Transit Gateway) to securely connect our core data compute engines (Snowflake, Redshift, Athena) and data stores (S3 Data Lakes) with our application and corporate environments
• Collaborate with DataOps teams to integrate Data Environment provisioning into CI/CD pipelines to ensure that all data infrastructure (e.g., Glue Catalog, EC2 for Spark/dbt runners, ECS clusters) is deployed consistently and securely
• Ensure all data-intensive services and their underlying compute/storage components are designed with disaster recovery and high-availability best practices
• Lead the strategic planning, design, and implementation of complex AWS networking solutions, including highly available and fault-tolerant VPC architectures, Subnets, Route Tables, and Network Access Control Lists (NACLs)
• Architect and manage secure, high-speed connectivity solutions between AWS and on-premises environments, utilizing technologies such as AWS Direct Connect, VPN, and Transit Gateway
• Design and optimize the deployment of compute services, including sophisticated configurations of EC2 instances and container orchestration using ECS (Elastic Container Service)
• Implement and enforce security best practices across all infrastructure, focusing on Identity and Access Management (IAM), Security Groups, and integrating services like AWS WAF and Shield
• Lead the development and maintenance of our cloud foundation using IaC tools to ensure immutable, repeatable, and scalable deployments
• Drive continuous optimization of AWS resource consumption and costs, utilizing RIs, Savings Plans, and automated scaling policies across all environments, including the data platform
• Automate routine operational tasks, infrastructure health checks, and security remediation using AWS Lambda, Systems Manager, and scripting languages (e.g., Python, Bash)
• Act as the top-tier technical expert for major infrastructure incidents, quickly diagnosing and resolving complex networking and platform issues to restore service availability

Requirements:

• 10+ years of progressive experience in designing, implementing, and managing large-scale cloud infrastructure, with a deep specialization in AWS
• Expert-level knowledge of AWS networking fundamentals, including TCP/IP, DNS, Routing, Load Balancing (ALB/NLB), and IP addressing schemas
• Proven experience with containerization and orchestration, specifically AWS ECS. Experience with EKS is a plus
• Deep practical experience with CI/CD and DevOps practices, focusing on infrastructure automation
• AWS Certification at a Professional level (e.g., AWS Certified Solutions Architect - Professional or AWS Certified Advanced Networking - Specialty) is highly desirable
• Collaboration: Excellent communication skills, capable of working effectively with Data Engineers, Data Scientists, and other teams
• Insurance industry experience preferred but not mandatory
