Job Code: A158444

Team Introduction:
The Site Reliability Engineering (SRE) team at Tik Tok combines software and systems engineering to build and run large-scale, massively distributed, and fault-tolerant systems. Our team is dedicated to ensuring that Tik Tok’s core services remain stable, efficient, and resilient at a global scale. We focus on enhancing the observability and operability of our infrastructure, using data-driven insights to safeguard business stability 24/7.

• System Design & Optimization:
  Participate in the full lifecycle of high-concurrency distributed systems. Collaborate with development teams to ensure services are designed for scalability, reliability, and high availability.
• Automation & Efficiency:
  Build and maintain robust automation tools to eliminate "toil," streamline service deployments, and manage infrastructure as code.
• Observability & Monitoring:
  Develop and refine monitoring, alerting, and logging systems (SLIs/SLOs) to provide deep visibility into service health and performance.
• Disaster Recovery (DR) & Resilience:
  Lead the design, implementation, and execution of global disaster recovery drills. You will simulate complex failure scenarios and validate failover mechanisms to ensure the platform remains operational under extreme conditions.
• Incident Management & Response:
  Serve as a key responder for high-priority production incidents. You will coordinate cross-functional "war rooms," drive technical troubleshooting, and lead the path to service restoration.
• Continuous Improvement:
  Facilitate blameless post-mortems and perform root-cause analysis (RCA). You will transform incident insights into engineering requirements to harden our systems against future outages.
• Capacity Planning:
  Manage resource allocation and performance bottlenecks to ensure the platform can handle organic growth and massive traffic surges.

• Bachelor’s degree in Computer Science, related technical field, or equivalent practical experience.
• Proficiency in one or more programming languages (e.g., Go, Python, Java, or C++).
• Strong understanding of Linux system internals, networking (TCP/IP, DNS, Load Balancing), and distributed systems.
• Experience managing containerized environments (e.g., Kubernetes, Docker).

• Proven experience in a high-traffic production environment with a focus on incident response and site stability.
• Hands‑on experience with Disaster Recovery strategies, including multi‑region failover and data consistency in distributed databases.
• Familiarity with observability and monitoring tools.
• Experience with Infrastructure as Code.
