Database Engineer

TEKsystems•Dallas, TX

1d•$65 - $70•Onsite

About The Position

We are building and operating an enterprise-scale, high-volume transactional database platform that supports end-to-end transaction processing. 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. Level (Senior vs. Lead) is determined by depth of scope and leadership impact.

Requirements

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.

Nice To Haves

Oracle Exadata experience (engineering/tuning/operations on Exadata platforms).
Oracle Data Guard experience (HA/DR, role transitions, validation of primary/standby states).
Oracle GoldenGate experience (replication design/operations).
Understanding of enterprise MySQL deployment/replication patterns (e.g., primary/replica cross-site patterns).

Responsibilities

Design and evolve an enterprise transactional data model for high-volume OLTP systems, including schemas, constraints, indexing strategies, partitioning, and retention/archival patterns.
Define database standards for reliability, scalability, performance, and resiliency across MySQL and Oracle.
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).
Design and support replication/data movement strategies for resiliency and/or cross-site requirements (preferred Oracle skills include GoldenGate and Data Guard).
Partner with security teams to enforce encryption-in-transit/at-rest, least privilege, auditing, secrets management integration, and vulnerability remediation for database platforms.
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.
