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 Cloud Infrastructure ( OCI )

  • 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

  • Systems administration and infrastructure engineering

  • GIS or enterprise data integrations

  • Enterprise document management and metadata-driven workflows

  • Data warehousing and dimensional modeling

  • Infrastructure/database automation and scripting

  • Technical project leadership

  • Infrastructure/database automation and scripting

  • Technical project leadership

  • Practical applications of AI in IT operations, database administration, or workflow automation

💡 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.

Interested? Apply today or reach out to learn more about the opportunity.
