The posting
Leidos is seeking a Lead Database Administrator/Engineer to serve as the senior technical authority for the on-premises Oracle database environment supporting (GEOINT product dissemination and expurgation processing.) This role will lead the architecture, administration, security, performance, availability, and lifecycle management of mission-critical Oracle databases. That includes spatial data stores that enable accurate, timely dissemination of product packages to internal and foreign partners. The ideal candidate will have deep expertise in Oracle Database engineering, high availability and disaster recovery, patching and upgrades, database security hardening, and automation. They must also have the leadership ability to guide a team of database and software professionals.
This position requires a highly collaborative leader who can engage across multiple offices, set database standards and best practices, mentor junior and mid-level staff, and ensure the database environment meets operational, security, and compliance requirements. Experience operating across multiple security domains is highly desirable. The role also requires a strong public-speaking presence: delivering briefings, advising leadership on database strategy and risk, and acting as the face to the customer for database-related technical discussions and stakeholder engagements.
