• Troubleshoot complex issues across applications, distributed systems, and networks in Linux-based environments.
• Partner closely with AWS and other engineering teams to scale Slack’s worldwide infrastructure and adopt new cloud technologies.
• Drive improvements in system observability, reliability, and ease-of-use by iterating quickly on designs and collaborating across engineering.
• Participate in on-call rotations to ensure the availability and resiliency of critical Slack infrastructure.
Qualifications:

• 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.
