Full-Time Senior Engineer, NSO

About the Job

This role will monitor the day-to-day operations of Life360’s services while also working to improve our overall observability and reporting capabilities. Life360’s system contains dozens of microservices, all of which are candidates for observation, tracking, and reporting. Onboarding new services and maintaining visibility of metrics for existing services are part of your responsibilities. This position is part of a strongly-knit team where good communication is a must. Life360 has on-call responsibilities for all engineers, which this position both supports and participates in. Responding to alerts as they come in, methodical execution of runbooks, and escalation of major issues to service owners will be daily events. The ability to quickly understand large systems at scale is critical. Thinking creatively about our system, gaining strong familiarity with the tools we use to maximize their benefits, and finding ways to automate manual tasks are behaviors that will elevate great engineers in this role.

• Use tools such as Prometheus, Grafana, and Datadog to create and maintain observability infrastructure and tooling, including creating alerts, production reporting, and writing documentation.
• Manage observability infrastructure.
• Serve as a member of “follow the sun” L1 on-call support, working alone or with teammates to answer pages for all onboarded services and resolve or escalate issues in a timely manner.
• Utilize anomaly detection and alerting, respond to alerts in PagerDuty, drive incidents to their conclusion, and lead the effort to strengthen the system based on post-mortem action items.
• Coordinate cross-team and cross-functional efforts with processes, documentation, and tooling to ensure operational excellence.

What We’re Looking For

• Bachelor's in Computer Science, Engineering, related field or equivalent practical experience
• 5+ years experience writing/reading/debugging code in one or more languages, such as: Java, Python, Shell, Ruby
• 5+ years experience working with large-scale distributed systems and managing Linux-based systems in a cloud like AWS
