What they need
🚀 SENIOR ORACLE DATABASE & SYSTEMS ENGINEER (3-6m contract w/conversion to FTE)
We’re looking for an experienced Oracle Database & Systems Engineer to join a team responsible for supporting and modernizing mission-critical enterprise technology.
This is more than a traditional DBA role.
You’ll work across Oracle databases, cloud infrastructure, systems engineering, architecture, security, performance, disaster recovery, and enterprise integrations —with a major opportunity to help drive a transition from on-premises environments to Oracle Cloud Infrastructure (OCI) .
If you enjoy solving complex technical problems, improving systems, and working across the technology stack, this role offers an opportunity to make a meaningful impact.
🔧 WHAT YOU’LL DO
Oracle Database & Engineering
Administer, maintain, monitor, and optimize enterprise Oracle databases and supporting infrastructure.
Perform backup and recovery, patching, troubleshooting, capacity management, and performance tuning.
Develop and support SQL and PL/SQL, including stored procedures, triggers, views, and other database components.
Maintain database availability, security, reliability, and data integrity across environments.
☁️ Cloud & Infrastructure
Help lead the migration of enterprise databases and related services from on-premises infrastructure to Oracle Cloud Infrastructure (OCI) .
Participate in migration planning, architecture, testing, validation, cutover, troubleshooting, and post-migration optimization.
Engineer and support database and system environments, infrastructure upgrades, hardware replacements, and recovery processes.
Work with virtualization, containerization, storage, networking, operating systems, and enterprise infrastructure technologies.
🏗️ Architecture & Data
Design and support database architectures, data models, integrations, and enterprise data services.
Apply principles of normalization, transactional integrity, data warehousing, dimensional modeling, and alternative data models.
Create technical documentation including entity-relationship diagrams, data-flow diagrams, architecture documentation, and solution designs.
🔐 Security, Performance & Reliability
Monitor database and infrastructure resources and identify opportunities to improve performance, scalability, reliability, and cost efficiency.
Manage database authentication, authorization, permissions, auditing, and environment controls.
Support security reviews, patch management, risk mitigation, and compliance requirements.
Contribute to business continuity, disaster recovery, backup/recovery, and overall system recoverability.
🔗 Enterprise Integration
Support integrations involving GIS, enterprise data services, document management systems, metadata, and document-retrieval workflows.
Partner with developers, GIS professionals, business stakeholders, contractors, and technical teams to translate business requirements into effective technical solutions.
Troubleshoot production issues, support users, and contribute to system enhancements and modernization initiatives.
Lead or contribute to projects involving database design, development, implementation, migration, and ongoing management.
🤖 AI & Modernization
Explore practical applications of Artificial Intelligence (AI) for database administration, automation, monitoring, reporting, workflow improvement, and operational efficiency.
Identify opportunities to use emerging technologies to modernize enterprise platforms and improve service delivery.
🎯 WHAT WE’RE LOOKING FOR
Required:
Bachelor’s degree in Computer Science, Information Systems, Information Technology, or a related field—or an equivalent combination of education and experience.
3+ years of relevant professional experience in database administration, systems engineering, infrastructure, or a related discipline.
Strong experience with relational databases, preferably Oracle .
Experience with SQL, PL/SQL, database performance analysis, and troubleshooting.
Understanding of enterprise infrastructure and multi-tier application environments.
Knowledge of database security, authentication, authorization, auditing, and access controls.
Experience with cloud computing concepts and enterprise infrastructure.
⭐ EXPERIENCE THAT WILL SET YOU APART

Oracle database migration and modernization
VMware and/or Hyper-V
Docker or other container technologies
Enterprise backup and disaster recovery
Database monitoring and performance-tuning tools

💡 WHY THIS ROLE IS INTERESTING
This position sits at the intersection of Database Administration + Cloud + Systems Engineering + Architecture .
You’ll have the opportunity to:
☁️ Help move enterprise workloads to the cloud
⚙️ Engineer and optimize mission-critical systems
🔐 Strengthen security, reliability, and recoverability
🏗️ Influence database and infrastructure architecture
🤖 Explore practical AI applications
🚀 Contribute to long-term technology modernization
👤 THE IDEAL CANDIDATE
You’re someone who can move comfortably between Oracle databases, infrastructure, cloud platforms, security, application integration, and business requirements .
You enjoy troubleshooting difficult problems, improving systems rather than simply maintaining them, and working collaboratively with both technical and non-technical stakeholders.
If you’re an experienced Oracle professional who wants to expand beyond traditional DBA responsibilities and play a key role in cloud migration, systems engineering, architecture, and modernization , we’d love to hear from you.
