• Support database migrations (on-prem → AWS, RDBMS → Cassandra where applicable).

• Partner with engineering teams on schema design, data modeling and scalability patterns.

• Participate in on-call rotations and drive incident response and root cause analysis.

What you will have

• 3+ years in database engineering, SRE, or platform engineering roles.
