• Establish and enforce security best practices, working closely with compliance teams on financial services requirements
• Design and implement disaster recovery, backup, and business continuity strategies
• Optimize system performance, cost efficiency, and resource utilization across AWS services

• Participate in incident response and conduct thorough post-mortems to drive continuous improvement
• Mentor engineers on Dev Ops practices, cloud architecture patterns, and operational excellence

• 8+ years of experience in Dev Ops, SRE, or infrastructure engineering roles
• Expert-level proficiency with AWS services including ECS Fargate, ALB, Cognito, S3, SQS, and related services
• Deep hands-on experience with Terraform for managing complex, multi-account AWS environments
• Strong scripting and automation skills in Python and/or Bash
• Proven experience designing and implementing CI/CD pipelines (Git Hub Actions, ArgoCD, or similar)
• Solid understanding of containerization technologies (Docker) and orchestration platforms (Kubernetes/ECS)
• Experience with observability and monitoring tools (Datadog, Cloud Watch, or equivalent)
• Deep knowledge of networking, security, and AWS best practices
• Strong problem-solving abilities and experience troubleshooting complex distributed systems
• Excellent communication skills and ability to work cross-functionally with engineering teams

• Have startup or early-stage experience
• Experience with PostgreSQL performance tuning and RDS management

• Build the foundation layer of an AI-native product
• High ownership + direct impact
