* Design efficient database schemas, business-aligned data models, data dictionaries and technical documentation covering integration points and data flows

* Improve database reliability, performance and security by proposing optimization techniques, validation rules, access controls, backup and recovery approaches, and error handling mechanisms

* Design data ingestion, transformation and quality-control patterns that standardize, clean and validate data from multiple sources, including automated workflows for recurring processing

* Support integration across systems by designing message queues and event-driven patterns, ensuring data consistency, troubleshooting synchronization issues and collaborating with internal and external teams

* Shape data initiatives into manageable work packages by estimating effort, defining timelines and helping set the technical roadmap for data infrastructure

* Enjoy collaborating with data scientists, analysts, engineers, business teams and external partners to agree pragmatic integration and data-management solutions

* Have a problem-solving mindset, strong attention to detail and the adaptability to learn new technologies, tools and approaches

* Are comfortable facilitating knowledge sharing, documenting decisions and helping teams reduce technical debt over time

Your background and skills include:

* Solid experience in data architecture and design, data modelling, data warehousing solutions and data integration patterns

* Proficiency in database design and management across SQL and NoSQL technologies, including schema design, constraints, stored procedures, functions and triggers

* Strong understanding of ETL processes and tools such as DataStage, Informatica and Snowflake ETL, plus familiarity with big data technologies such as Hadoop and Spark and Kafka event streaming

* Proficiency in UML, especially ERD, sequence and component diagrams, together with an understanding of BPMN and end-to-end process thinking

* Good working knowledge of data governance principles, data quality practices, performance optimization, debugging/troubleshooting and CI/CD pipeline concepts

It would be ideal if you also:

* Have hands-on experience documenting complex data flows, integration landscapes and data dictionaries in regulated environments

* Have designed event-driven or queue-based integration patterns and helped define operational recovery mechanisms for critical data processes

* Can support communities of practice through knowledge-sharing sessions, architecture guidance and reusable documentation standards
