Role Description

We’re working with a leading organization seeking a highly experienced Oracle Database Developer with hands-on expertise in Exadata Cloud at Customer (ExaCC) and deep knowledge of Oracle 19c internals. This is a senior-level role for someone who goes beyond conventional database development — an expert who understands the engine under the hood and can design, optimize, and troubleshoot with precision.

Key Responsibilities

• Design and optimize high-performance Oracle database solutions, with specific focus on ExaCC environments.
• Troubleshoot complex performance issues using internal diagnostics (e.g., ASH, AWR) rather than canned tools.
• Collaborate with architects and data modelers to refine and challenge schema designs.
• Build reusable components and streamline legacy database code.
• Work closely with DevOps teams using OpenShift, CI/CD tools (Jenkins, GitHub Actions), and scripting (e.g., Bash, Python).
• Contribute to systems design with a strong emphasis on observability and supportability.

Key Skills & Experience

• 10+ years of Oracle database development with at least 2 years in ExaCC and Oracle 19c.
• Expertise in SQL, PL/SQL, and advanced performance tuning (e.g., bind variable peeking, cursor sharing, hard parsing).
• In-depth understanding of Oracle internals, including wait events, cardinality feedback, and histograms.
• Experience with both OLTP and Data Warehouse tuning approaches.
• Familiar with containerized deployments and CI/CD best practices.
• Comfortable presenting complex concepts to both technical and non-technical audiences.
• Must have proven experience in Credit Risk - Stress Testing

Nice to Have

• Experience with Liquibase/Flyway, monitoring tools (Prometheus, ELK, Grafana).
• Exposure to cloud platforms (e.g., GCP, AWS).
• Familiarity with data warehousing patterns (e.g., SCDs, fact tables, junk dimensions).

Benefits include:

• 25 days holiday plus bank holidays
• pension
• Death in service (4x salary)
• Dental
• Private medical
• flexible working policy - 2 days on site
