Staff Software Engineer (L4)

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
