Job Description

Company: Systems Development and Analysis
Location: Ashburn, VA / Hybrid / Remote

Employment Type: Full-time

About the Role

We are seeking a Database Administrator to support a federal client through a significant modernization effort. Today the environment is a production Oracle estate; over the life of this program, substantial portions of it are moving to managed cloud PostgreSQL and to Databricks for analytics. This is not a steady-state caretaker role. You will keep the existing Oracle systems healthy and performant while simultaneously planning, executing, and validating the movement of that data into the cloud.

What You’ll Do / Key Responsibilities

  • Oracle Database Administration: Administer production Oracle databases (19c or later) including installation, configuration, patching, upgrades, and RMAN backup and recovery.
  • High-Availability & Performance: Configure and maintain high-availability and disaster-recovery architectures (Data Guard, RAC, ASM) and diagnose/resolve performance issues through execution plan analysis and SQL tuning.
  • Cloud Migration: Plan and execute the migration of Oracle schemas and workloads to managed cloud PostgreSQL, including data type mapping, PL/SQL conversion, and cutover sequencing using tools like GoldenGate, AWS DMS/SCT, or Ora2Pg.
  • Postgres Tuning & Support: Administer and tune PostgreSQL in the cloud post-migration, optimizing vacuum/autovacuum strategy, connection pooling, replication, and parameters.
  • ETL & Data Pipelines: Build, support, and troubleshoot ETL/ELT pipelines moving operational data into Databricks and Delta Lake for analytics consumption.
  • Data Architecture & Governance: Perform logical and physical data modeling, implement database security controls (encryption, RBAC, auditing), and apply federal security hardening requirements (DISA STIGs, NIST 800-53).

Requirements & Qualifications

  • U.S. Citizenship required; must be able to obtain and maintain a U.S. Customs Background Investigation (BI).
  • Bachelor’s degree in Computer Science, Information Systems, Engineering, or a related technical field (or equivalent experience substitution).
  • Eight (8) or more years of hands-on database administration experience in production environments (Senior level); five years considered for Mid level.
  • Demonstrated depth in Oracle administration (backup/recovery, tuning, HA) or equivalent depth in another enterprise RDBMS at comparable scale.
  • Advanced SQL proficiency and working knowledge of PL/SQL or equivalent procedural language.
  • Demonstrated experience migrating, replicating, or synchronizing large datasets between systems.
  • Scripting proficiency for automation using Python, Bash, or equivalent.

Preferred / Bonus Qualifications (if applicable)

  • PostgreSQL administration, particularly managed cloud offerings (Amazon RDS/Aurora, Azure Database for PostgreSQL, or Cloud SQL).
  • Experience with Databricks, Apache Spark, and Delta Lake.
  • Hands-on experience with Oracle-to-PostgreSQL migration tooling (GoldenGate, AWS DMS/SCT, Ora2Pg).
  • Experience with CI/CD tools (Liquibase, Flyway) and infrastructure as code (Terraform, Ansible).
  • Prior work in a FedRAMP, GovCloud, or federal cloud environment supporting agencies like DHS or CBP.
