Your skills will include

• 8+ years of experience in DevOps, 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 (GitHub Actions, ArgoCD, or similar)
• Solid understanding of containerization technologies (Docker) and orchestration platforms (Kubernetes/ECS)
• Experience with observability and monitoring tools (Datadog, CloudWatch, or equivalent)
• Deep knowledge of networking, security, and AWS best practices
• Strong problem-solving abilities and experience troubleshooting complex distributed systems

• Experience managing AI/ML infrastructure and AWS Bedrock

What we offer:
