Migration Strategy Ownership: Lead the end-to-end technical analysis and architectural design for high-visibility enterprise migration initiatives.
Modern Cloud Ecosystems: Expand your technical portfolio by administering hybrid data environments across both on-premise infrastructure and GoCloud platforms.
Responsibilities
Database Engineering & Production Support
Create, implement, and maintain complex physical database designs, managing the overall database management system (DBMS) lifecycle.
Maintain, monitor, and optimize a large portfolio of Oracle 10g, 11g, 12c, and 19c databases inside high-volume, multi-tenant enterprise landscapes.
Design, build, and configure robust Oracle Database Servers across heterogeneous operating systems including Windows, Solaris, and Linux.
Execute expert-level performance tuning, database optimization, proactive capacity planning, growth forecasting, and storage sizing.
Ensure underlying databases continuously meet strict performance requirements for integrated applications, including Siebel CRM, Java web apps, ArcGIS, and Oracle APEX.
Provide elite, tier-3 database administration technical expertise during the initial design, discovery, and architecture phases of new digital initiatives.
Migration, Automation & Advanced Controls
Lead, architect, and deliver end-to-end solutions for enterprise Oracle migration projects to transition legacy configurations safely to Oracle 19c or higher.
Coordinate, plan, and automate complex data refresh routines from production down into lower, non-production staging environments.
Provide technical implementation support for advanced database utilities, including Transparent Data Encryption (TDE), Oracle Data Guard, RAC, Oracle Management Server (OMS), and Oracle Enterprise Manager (OEM) 13c.
Perform specialized systems analysis, impact evaluations, and implementation planning for software patches, maintenance packs, and comprehensive technology stack releases.
Manage and maintain distributed data systems, database gateways, middleware configurations, and data distribution replication rules.
Security, Risk Governance & Knowledge Transfer
Enforce ironclad database security parameters, setting up robust auditing controls to comply fully with enterprise security, data privacy, and compliance guidelines.
Research, isolate, and deploy rapid technical remediations for identified cybersecurity vulnerabilities across database tiers.
Formulate detailed technical risk assessments, profiling, prioritizing, and communicating architectural threats and mitigation strategies directly to decision-makers.
Translate abstract data bottlenecks and complex infrastructure blocks into plain language, ensuring clear communication across technical squads and business partners.
Author and maintain exhaustive technical blueprints, runbooks, and schema maps to facilitate seamless knowledge transfer and long-term team sustainability.
Qualifications
Core Technical & Database Requirements
Professional Database Tenure: 10+ years of progressive, hands-on experience in Database Analysis and Administrator roles, focusing on enterprise-scale architectures.
Oracle Ecosystem Mastery: Extensive experience configuring, maintaining, optimizing, and fine-tuning Oracle 10g, 11g, 12c, and 19c environments within large multi-tenant configurations.
Multi-OS Infrastructure Savvy: Proven track record designing and configuring database servers running across Linux, Solaris, and Windows platforms, utilizing advanced query languages and scripts.
Advanced Oracle Tooling Depth: Practical experience deploying and managing high-availability and security configurations, specifically TDE, Data Guard, RAC, and OEM 13c.
Large-Scale Migration Success: Demonstrated success executing complex database migrations from end-of-life legacy platforms to modern supported versions across hybrid cloud and on-premise data centers.
Methodologies & Governance Capabilities
Change & Release Governance: Strong working knowledge operating within structured Incident, Change, and Configuration Management frameworks (ITIL-aligned).
Enterprise Architecture & Data Warehousing: Foundational familiarity with Ontario Government Enterprise Architecture processes, reference gating, and data warehouse/data mart structures (including Oracle OBIEE).
System Modeling Tools: Prior experience utilizing Computer-Aided Software Engineering (CASE) tools or object-oriented design techniques to model data environments is an asset.
Communication & Team Collaboration
Technical Articulation: Outstanding written and verbal communication skills, with a proven ability to translate complex database issues into plain language for diverse stakeholders.
Consensus & Relationship Building: Strong interpersonal skills used to drive technical outcomes, align cross-functional engineering teams, and resolve systemic environment blockers.
Knowledge Optimization: A collaborative team player with an exceptional track record for meeting fixed delivery deadlines and authoring top-tier technical documentation.
