About the team：

Site Reliability Engineering (SRE) at TikTok combines software and systems engineering to build and run large-scale, massively distributed, and fault-tolerant systems. In our team, you’ll have the opportunity to manage the complex challenges of scale, while using expertise in coding, algorithms, complexity analysis, and large-scale system design. We embrace a culture of diversity, intellectual curiosity, openness, and problem-solving. We encourage close collaboration while promoting self-direction.

Responsibilities

• Develop and maintain automation procedures to maximize system efficiency and minimize human intervention.
• Work closely with software engineering teams to design, deploy and operate elements to ensure that systems are functionally robust.
• Ensure system scalability to handle growth in web traffic and data.
• Implement monitoring tools and set up metrics to keep track of system health and performance.
• Participate in on-call rotations, assist with incident management, and diagnose, resolve, and prevent production issues.
• Conduct performance tests to find and address system bottlenecks.
• Collaborate with teams across the organization to define Service Level Objectives (SLOs), Service Level Indicators (SLIs), and Service Level Agreements (SLAs).
• Practice sustainable user support, incident response, and blameless postmortems.
