Twilio is looking for a Staff Site Reliability Engineer to join our Platform Engineering organization. SRE owns production health and resiliency at Twilio — we are accountable for whether our services stay available, performant, and recoverable for the customers who build their businesses on us.
Responsibilities
- In this role, you’ll
- Own the reliability posture of production services in your area — availability, latency, capacity, efficiency, performance, and the monitoring and alerting that makes them visible
- Define, instrument, and operate against SLIs and SLOs, and use error budgets to drive engineering priorities
- Identify trends and problem areas that threaten stability, and provide a path forward to mitigate risk before it reaches customers
- Drive down repair items and prevent classes of incidents rather than resolving them one at a time
- Improve detection, response, and recovery — reducing time to acknowledge, engage, mitigate, and restore, with fewer people pulled in
- Design for failure: strengthen failure domains, validate recovery paths, and make production changes safer to ship and safer to roll back
- Participate in on-call for the services you support, and lead the response when production is degraded
- Write post-mortems that identify true root causes, and drive the follow-up work to completion
- Oversee efforts to identify, diagnose, report, and document production problems across all reliability dimensions
