01Role Summary

Our client is seeking a Senior Oracle PL/SQL Developer for a long-term consulting assignment within a complex, business-critical IT environment. The consultant will join an experienced team responsible for the development and maintenance of databases and backend solutions.

This is a hands-on development role with a strong focus on Oracle PL/SQL, database-centric business logic, and transaction-intensive systems. The environment handles large data volumes, parallel processes, and critical transaction flows, with demanding requirements for stability, performance, and availability. A significant portion of the business logic is implemented directly in the database through SQL and stored procedures. Microservices developed in Java and .NET operate above the database layer and communicate with different business functions and external systems.

The position is specifically focused on Oracle PL/SQL development and business logic. It is not a traditional database administrator role and does not focus on Data Warehousing or Business Intelligence.

02Key Responsibilities

• Develop, maintain, and enhance database functionality and business logic using Oracle PL/SQL and SQL.
• Design and maintain stored procedures and other database-centric application components.
• Troubleshoot database code and resolve issues in complex, transaction-intensive backend systems.
• Analyze and optimize database performance across large-scale Oracle environments.
• Work with high-volume data processing, parallel processes, and critical transaction flows.
• Develop and maintain integrations and data flows between databases, microservices, external partners, and connected systems.
• Collaborate closely with senior developers and architects on technical solutions, system enhancements, and improvements to existing platforms.
• Understand complex business processes and translate functional requirements into reliable database-level implementations.
• Contribute ideas, technical improvements, and knowledge sharing within a senior, international engineering team.

03Technical Stack & Requirements

• Database platform: Extensive, current hands-on experience with Oracle Database and PL/SQL development.
• Database programming: Advanced SQL skills, including stored procedures and database-centric programming.
• Performance: Experience troubleshooting and optimizing code in large database environments with stringent performance and availability requirements.
• Backend architecture: Experience working with complex, transaction-intensive backend systems and high-volume data processing.
• Microservices: Understanding of microservices architecture and backend services developed with Java or .NET is advantageous.
• Integrations: Experience implementing data flows and integrations with external partners and systems is advantageous.
• Business systems: Experience with billing platforms, CRM solutions, or other business-critical transaction systems is beneficial.

04Qualifications & Experience

The successful consultant will have substantial and recent practical experience in Oracle PL/SQL development, together with a strong understanding of SQL, stored procedures, business logic, and transaction flows. Experience diagnosing technical issues, improving performance, and solving problems in large Oracle environments is required. The role also requires the ability to work independently, take initiative, and quickly understand complex technical environments and interconnected business systems.

Previous experience in banking, financial services, energy, or another transaction-intensive industry is advantageous. The consultant should be comfortable collaborating with experienced developers and architects while contributing to technical discussions and continuous system improvement. Professional fluency in spoken and written English is required.
