• Establish resilience strategies to proactively uncover weaknesses and validate recovery strategies
• Collaborate with product and engineering teams to define SLOs and error budgets to ensure services are reliable, scalable and observable
• Identify and eliminate toil across engineering, building the automation, playbooks and runbooks that reduce MTTR and become the patterns other teams adopt
• Partner on security posture and compliance metric reviews related to operational reliability
• Grow reliability expertise across engineering
• What You Need To Succeed
• Bachelor’s degree in Computer Science, a related field or equivalent practical experience
• 8+ years of experience with Saa S software development in distributed systems using languages such as Kotlin/Java, Typescript, Python and technologies like Ia C, Docker and Kubernetes
• 4+ years’ experience designing, operating and analyzing large-scale troubleshooting distributed systems
• Good knowledge of modern application/infrastructure monitoring concepts (Datadog experience advantageous)
