Staff, Database Reliability Engineer L4

Posted Aug 9

This position is needed to help operate and troubleshoot a number of business-critical MySQL database clusters. Some of these clusters receive in excess of 1 billion writes per day, and rely on internally developed toolkits to help orchestrate backups, pivots, and other routine management tasks. As Twilio’s scale necessitates the move to managed databases like AWS Aurora, AWS Elasticache for Redis, we are looking for a team of database SREs who can help keep the existing self-managed clusters running while also helping with migrations to managed alternatives.


In this role, you’ll:

  • Be responsible for the operational health of several business-critical HA MySQL clusters running on EC2.
  • Be responsible for improving monitoring and alerting practices around database health.
  • Help diagnose operational issues, and develop and implement proposals for fixing them.
  • Have a critical role in shaping the next-generation of database tooling at Twilio focused on managed databases.
  • Help teams migrate to managed databases in a piecemeal fashion according to their needs.
  • Meet critical latency, availability, and reliability goals and service level objectives.
  • Collaborate with software engineering and operations teams to quickly highlight and resolve problems with database and its connected systems.


Not all applicants will have skills that match a job description exactly. Twilio values diverse experiences in other industries, and we encourage everyone who meets the required qualifications to apply. While having desired qualifications make for a strong candidate, we encourage applicants with alternative experiences to also apply. If your career is just starting or hasn't followed a traditional path, don't let that stop you from considering Twilio. We are always looking for people who will bring something new to the table!


  • 5+ years in a role that involves DB administration, e.g., DB SRE, DBA, etc.
