• Write and optimise DDL scripts for different database management systems.
• Develop and optimise complex SQL queries, stored procedures, functions and triggers.
• Translate user and application requirements into efficient database structures.
• Prototype database solutions (schemas, queries, test datasets) for validation before production rollout.
• Design and execute test plans for database components, including unit tests and data integrity tests.
• Troubleshoot performance issues, tune queries and implement indexing strategies.
• Implement database security policies, access controls and data encryption.
• Design and implement data migration, backup, recovery and high-availability strategies.
• Support the deployment, configuration and release management of database components.
• Write technical specifications for AI code agents (e.g. Kiro) and review their outputs for correctness, security and performance.
• Write technical documentation.

What we're looking for

• University degree corresponding to Level 6 of the European Qualifications Framework (typically a Bachelor's degree or 3 years of higher education) and minimum 7 years of professional IT experience, or a secondary education diploma giving access to higher education and minimum 12 years of professional IT experience.
• Proven experience as a Database Engineer, Database Developer or similar role.
• Good knowledge of SQL and procedural SQL extensions such as PL/SQL (Oracle) or PL/pgSQL (PostgreSQL).
• Experience in data modelling (conceptual, logical, physical) with tools such as Oracle SQL Developer Data Modeler, Hackolade or NoSQL Workbench.
• Good knowledge of non-relational databases (e.g. MongoDB, DynamoDB, Cassandra, Cosmos DB).
• Knowledge of performance optimisation (query tuning, indexing, execution plans).
• Experience with backup, recovery and high availability (replication, clustering).
• Good experience with database release management and Agile practices (Scrum, Kanban) applied to database delivery.
• Knowledge of data security and compliance practices.
• Ability to write clear, structured technical documentation and present to different types of stakeholders.
• English or French language proficiency at B2 level or higher.

Nice to have

• Knowledge of database unit testing frameworks (utPLSQL, SQLTest).
• Experience integrating AI coding tools (e.g. Kiro, GitHub Copilot) into development workflows, with awareness of their limitations.
• Experience with grant management or large-scale public sector systems.
• Previous experience working within European Institutions or large international organisations.

What We Offer:

• Prestigious projects within European institutions.
• International, innovative, and multicultural environments.
• Continuous support from a team of experts in EU projects.
