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.

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.
