Database Engineer

Description
About the role
We are building and operating an enterprise-scale, high-volume transactional database that supports all lending payment transactions end-to-end. This role designs, builds, and maintains highly available, performant, and secure data stores and data movement patterns across MySQL and Oracle platforms, partnering closely with application engineering, SRE/operations, and security teams.
You will be accountable for database architecture and implementation decisions that directly impact transaction integrity, latency, resiliency, and operational excellence.
What you'll do (core responsibilities)
Architecture & Design
Design and evolve an enterprise transactional data model for lending payment processing (OLTP), including schemas, constraints, indexing strategies, partitioning, and retention/archival patterns.
Define database standards for reliability, scalability, performance, and resiliency across MySQL and Oracle.
Build & Operate (Production Ownership)
Implement and operate high availability and disaster recovery patterns; validate operational readiness (failover/failback, replication health, recovery objectives).
Drive performance engineering: query tuning, index strategy, execution plan analysis, contention/locking analysis, and workload management.
Implement automation for database operations (provisioning support, patch readiness support, backup validation, health checks, and runbook-driven execution).
Data Movement & Replication
Design and support replication/data movement strategies as needed for resiliency and/or cross-site requirements (preferred Oracle skills include Golden Gate and Data Guard).
Security & Compliance
Partner with security to enforce encryption-in-transit/at-rest, least privilege, auditing, secrets management integration, and vulnerability remediation for database platforms.
Cross-team Collaboration
Work closely with application teams on schema evolution, release coordination, and safe migration approaches (including MySQL ? Oracle considerations).
Produce durable documentation: architecture diagrams, decision records, runbooks, and operational validation checklists.

Additional Skills & Qualifications
Required qualifications
Strong hands-on experience designing and operating high-volume, enterprise OLTP databases supporting mission-critical transactions.
Advanced SQL and performance tuning experience across MySQL and Oracle (query tuning, indexing, partitioning, execution plan analysis).

Experience with operational best practices: backup/restore validation, patch planning, monitoring/alerting, incident response, and runbooks.
Proven ability to collaborate across engineering, operations, and security with clear, structured communication.
Preferred qualifications (Oracle focus)
Oracle Exadata experience (engineering/tuning/operations on Exadata platforms).
Oracle Data Guard experience (HA/DR, role transitions, validation of primary/standby states).
Oracle Golden Gate experience (replication design/operations).
Understanding of enterprise MySQL deployment/replication patterns (e.g., primary/replica cross-site patterns).
Technical Questions: several technical questions, including the following:
- Provide high-level steps for migrating a MySQL DB to Oracle (Exadata).
- Which tools do you use to monitor and troubleshoot MySQL database issues?
- What approach do you follow to investigate the root cause of a DB crash?
- Would you recommend using non-relational databases for certain application migrations?
Some tools we need to be familiar with:
Erwin data Modeler, Dynatrace for monitoring.
