Position Summary

We are seeking a Staff Database Engineer (Official Title: Staff Database Engineer I) with experience managing large-scale, mission-critical environments that require zero downtime. As part of the SHEIN DBRE team, you will play a key role in ensuring the reliability, performance, and security of our database infrastructure through automation and scalable solutions. Our team integrates DBA, SRE, and DBRE expertise to deliver highly available data services. We design resilient architectures to meet evolving business and data processing demands, prioritizing efficiency and system reliability.

• Manage database upgrades, migrations, and schema changes while ensuring minimal disruption and improved performance.
• Triage and resolve database issues, driving incidents to resolution and implementing preventative measures.
• Conduct capacity planning and benchmarking across multiple database technologies.
• Ensure data integrity, high availability, security, and privacy compliance across all database environments.
