Database Administrator

Ingenico Group

Suresnes, France

Mission

As Database Administrator and reporting to the Head of Infrastructure in France, you will join a large team dedicated to the design and development of the Ingenico Cloud Platform. You will be responsible for designing, building, and maintaining highly resilient infrastructure and database solutions that underpin real-time financial transactions with high data integrity requirements, and requiring near-zero downtime, seamless scalability, and comprehensive security controls to protect sensitive information and ensure compliance. You will play a pivotal role in ensuring global redundancy, data consistency, low replication lag, and latency management, as well as the complexity of orchestrating failovers and disaster recovery across geographically dispersed locations. You will be well-versed in various strategies to address these complexities, such as distributed database architectures, advanced replication and synchronization techniques, data partitioning, and consistency models that meet the demands of high-availability financial systems. You will also support research and development efforts, bridging the gap between infrastructure and development, offering strategic insights into database optimization, performance tuning, troubleshooting while collaborating closely with R&D teams and Architects.

Responsibilities

Within infrastructure team:

Design, deploy, and maintain highly available and resilient databases infrastructure to meet the needs of mission critical financial applications.
Collaborate on multi-region database deployments, ensuring robust disaster recovery, high availability, and minimal replication lag.
Monitor database health and performance metrics, identifying and resolving bottlenecks, replication issues, and other system anomalies.
Manage and automate regular maintenance tasks, including backups, indexing, patching, and upgrades, while minimizing disruption to operations.
Develop and test disaster recovery and failover strategies, ensuring minimal data loss and downtime across regions in the event of failures.

With the R&D and Architects:

Partner with R&D teams to optimize database query performance, improving response times and reducing latency across applications.
Act as a technical advisor on database design best practices, ensuring new architectures align with transactional, performance, and multi-region consistency requirements.
Collaborate on designing and implementing data models, indexes, and partitioning strategies that support rapid data access and minimize latency in distributed deployments.
Support the development of new features by proactively identifying and resolving database-related performance issues during the design and testing phases.
Provide guidance on the impact of design and architecture choices on data consistency, availability, and durability, particularly in multi-region and distributed setups.
Mentor and train R&D teams on best practices in data access and storage to support efficient and performant database usage across the organization.
