• Prior experience deploying, operating, and debugging server software on Linux.
• Strong interpersonal and communication skills; able to explain complex technical concepts to designers, support staff, and fellow engineers.
• A BS, MS, or Ph.D. in Computer Science, Engineering, or related technical field (or equivalent work experience).
Preferred:
• A domain expert within the AWS ecosystem (NLB, VPC / IAM / S3 / EC2)
• Experience contributing to or operating large-scale, highly available production systems.
• Knowledge of DDoS detection/mitigation strategies and automation frameworks.
• Interest in cost optimization and operational efficiency at cloud scale.
