Key Responsibilities SRE Leadership: Manage and mentor a team of SREs, managing weekly sprints, providing technical guidance, fostering a collaborative environment to achieve team goals, and focusing on building a culture of high performance. Collaborate with your peers in Platform Engineering and Application Development to ensure the reliability of what gets deployed to production. This is a hands-on roll that requires coding, code reviews, and strong technical guidance. Monitoring and Alerting: Utilize monitoring systems to proactively identify potential issues and act on them immediately before they become disruptive. Eliminate red blindness and ensure high fidelity, actionable alerts by adhering to best practices for alert implementations and thresholds. Continually optimize for better observability and actionable alerting. Reliability Engineering: Build a culture of reliability by collaborating with Platform Engineering and Application Development teams at design time on through to implementation and test. Enforce reliability and resilience by ensuring systems are built to be HA through proper design, code reviews, and rigorous testing of modes of failure. Performance and Scalability Optimization: Identify bottlenecks using profilers and distributed tracing frameworks. Implement performance improvements across Calix's infrastructure. Work cross-functionally with development teams to guide them toward better performance, scalability, and cost efficiency. Capacity Planning: Proactively monitor system performance and capacity, identifying potential bottlenecks and scaling systems as needed. At Calix, we are constantly growing, making sure that we are scaling appropriately is an area of constant focus. Automation Development: Drive the development and implementation of automation tools to streamline operations, including deployment pipelines, monitoring, and self-healing mechanisms.

Ensure that incidents never repeat. Implement and Enforce SLI’s/SLO’s: Ensure that all service endpoints and critical user journeys are monitored, visualized, have alerts, and have associated SLO’s. Work closely with development teams, product owners, and other stakeholders to ensure alignment and enforcement of SLO’s and error budgets. On-Call Management: Establish and manage on-call rotations for the SRE team, ensuring timely response and resolution to system alerts and incidents. You will blend skills and experience levels to ensure a well-rounded team of responders capable of handling a diverse range of production issues. Clearly define the duties of on-call staff. This includes outlining their responsibilities for monitoring alerts, maintaining playbooks, eliminating toil, handover protocols, troubleshooting incidents, escalating issues, and collaborating with other teams.
