Who we are

 

We are looking for a Data Architect responsible for defining and driving the data architecture strategy for the modernisation of a legacy application, migrating from Oracle to AWS-native data platforms. This includes redesigning the data model for PostgreSQL and NoSQL databases, leading data migration activities, and ensuring data integrity, performance, scalability, and security throughout the transformation.
The role works closely with solution architects, application developers, cloud engineers, and business stakeholders to ensure the modernised data landscape aligns with functional and non-functional requirements.

 

What you'll be doing

 

  • Define the target data architecture for AWS, including PostgreSQL and NoSQL (e.g. DynamoDB, MongoDB, or similar) components
  • Analyse the existing Oracle relational data model and identify refactoring opportunities for cloud-native and NoSQL paradigms
  • Design logical and physical data models for PostgreSQL and NoSQL, optimised for performance, scalability, and access patterns
  • Lead and govern the data migration strategy, including schema conversion, data transformation, validation, and reconciliation
  • Select and define migration tools and approaches (e.g. AWS DMS, custom ETL pipelines)
  • Define data standards, naming conventions, and data governance principles
  • Ensure compliance with security, privacy, and regulatory requirements, including encryption, access control, and auditability
  • Collaborate with development teams to support application refactoring related to data access and persistence
  • Support performance tuning, query optimisation, and capacity planning in the target environment
  • Provide guidance on data lifecycle management, backup, recovery, and disaster recovery strategies
  • Document data architecture decisions, migration plans, and target-state designs

 

What you'll bring along

 

  • Bachelor’s and/or master’s degree in computer science, Engineering or related technical discipline
  • Certification required: CBDA, CFLBA, CPRE, PBA or equivalent
  • Strong experience as a Data Architect in application modernisation or cloud migration projects
  • Deep expertise in relational databases, particularly Oracle and PostgreSQL
  • Hands-on experience designing and implementing NoSQL data models
  • Strong understanding of data modelling patterns (relational vs NoSQL, CQRS, event-driven data, etc.)
  • Experience with AWS data services, such as RDS/Aurora PostgreSQL, DynamoDB, S3, Glue, DMS
  • Proven experience leading large-scale data migrations with minimal downtime
  • Solid knowledge of SQL, data transformation, and data quality management
  • Familiarity with cloud security and IAM concepts related to data platforms
  • Strong communication skills and ability to translate business requirements into data designs
    Nice to Have
  • Experience modernising monolithic applications into cloud-native or microservices architectures
  • Knowledge of event streaming or data integration platforms (e.g. Kafka, Kinesis)
  • Experience with DevOps / DataOps practices and CI/CD for database changes
  • AWS certification (e.g. Solutions Architect or Data Analytics)
