Core Production Engineer - Onsite in San Francisco or Sunnyvale, CA.

What You'll Be Working On:
As a CORE PE, you will engage in incident response drills, post-mortems, and root cause analysis sessions to learn from past issues and prevent future ones.
Each morning starts with a structured review of overnight alerts and system performance metrics - identifying any anomalies, triaging what needs attention
You will collaborate with your team in a morning stand-up meeting to discuss ongoing projects, recent incidents, and priorities for the day.
Your tasks will include automating routine processes, analyzing system logs, and developing tools to enhance our monitoring capabilities.
You'll spend part of your day working closely with software engineers, advising on best practices for resilient code and reviewing changes before deployment
Throughout the day, your focus is on maintaining high SLIs and SLOs, ensuring that our infrastructure remains robust and reliable for our customers.
By day's end, you will document your work, share insights with your team, and plan for the next day's challenges, always with a customer-centric mindset.

Strong experience with architecture, design patterns, reliability and scaling of new and current systems
Experience leading and commanding incidents, including driving root cause analysis, coordinating cross-functional teams, and ensuring follow-through on corrective actions
