Are you an experienced Oracle Database professional looking to take ownership of enterprise-scale database technologies and influence how they are deployed, secured and supported?

Join our database engineering team as a Lead System Engineer specialising in Oracle Database technologies. In this senior technical role, you’ll help shape the standards, security, lifecycle and operational readiness of Oracle database platforms used across the business.

You’ll work hands-on with Oracle Database and Oracle Client technologies, database patching and security, UNIX/Linux and Windows environments, while partnering with DBAs, application teams, infrastructure, security teams and technology vendors.

This is an opportunity for an experienced Oracle professional who enjoys solving complex technical challenges and wants to have an impact beyond the day-to-day administration of individual databases.

What You’ll Do

• Lead Oracle Database Engineering: Own certification and technical readiness activities for Oracle Database and Oracle Client, including new database versions, upgrades, operating system changes and supported UNIX/Linux and Windows platforms.
• Drive Oracle Security & Patching: Lead recurring Oracle security patch certification and vulnerability remediation activities, including patch acquisition, staging, testing, troubleshooting, release guidance and installation templates.
• Shape Oracle Technology Standards: Help define and maintain supported versions, technology standards, lifecycle requirements and usage guidance for Oracle Database, Oracle Client and related database technologies.
• Manage Oracle Software & Tools: Maintain enterprise software distribution capabilities, including Oracle software repositories, patch bundles, Oracle Client and Instant Client packages, tools and staging environments.
• Solve Complex Technical Challenges: Investigate certification, compatibility, patching and deployment issues and work with technical teams and vendors to drive them through to resolution.
• Provide Technical Leadership: Act as a trusted Oracle technical resource for DBAs, application teams, infrastructure, desktop services and security teams, providing guidance on database technology, security and deployment.
• Support a Broader Database Ecosystem: Contribute to the lifecycle management of additional database technologies and tooling, including MongoDB Compass.
• Share Knowledge: Create clear technical guidance, certification procedures, technology advisories and support documentation, while mentoring and supporting other technical resources.

What You’ll Need

We’re looking for someone with strong Oracle Database expertise and a solid understanding of enterprise database environments.

• 5+ years of relevant experience in Oracle database administration, database engineering, systems engineering or related technical operations.
• Strong hands-on knowledge of Oracle Database and Oracle Client technologies.
• Experience with Oracle database patching, upgrades, security patches and vulnerability remediation.
• Strong understanding of database security and enterprise security requirements.
• Experience supporting Oracle technologies across UNIX/Linux and/or Windows environments.
• Experience troubleshooting complex database, compatibility, deployment or patching issues.
• Understanding of enterprise database software deployment and lifecycle management.
• Experience working with vendor support and coordinating resolution of complex technical issues.
• Ability to communicate technical risks and recommendations clearly to different stakeholders.

Experience with MongoDB or other database technologies is welcome but is not the primary focus of the position.

A bachelor’s degree in Computer Science, Information Systems, Engineering or a related technical field is preferred. Relevant Oracle, database, security, cloud or systems certifications are an advantage.

What You’ll Bring

This is a senior individual contributor position, so you won’t have direct reports. Instead, you’ll provide technical leadership through your Oracle expertise, ownership and influence.

You’ll have the opportunity to:

• Become a key technical authority for Oracle technologies within a large enterprise environment.
• Influence how Oracle database technologies are certified, secured, patched and deployed across the organisation.
• Work on complex problems involving database security, operating systems, infrastructure and enterprise applications.
• Collaborate with experienced database, security and infrastructure professionals.
• Mentor colleagues and influence technical standards without moving away from hands-on technology
