Summary: The Lead AWS Data Architect role involves designing and evolving a Payments Data Platform using AWS technologies. This hands-on position requires expertise in data architecture, engineering, and product ownership, focusing on ingesting payment events and optimizing data products. The architect will manage SLAs, backlogs, and performance across various domains, ensuring high-quality data governance. The role is contract-based for a minimum of six months and is classified as inside IR35.

Key Responsibilities:

  • Design, build, and evolve a next-generation Payments Data Platform.
  • Ingest ISO 20022 payment events into an AWS-based Lakehouse architecture.
  • Drive end-to-end delivery across Customer Experience (CX), Payments, and CPO domains.
  • Define SLAs and manage backlogs.
  • Ensure observability and optimize cost and performance across the platform.

Key Skills:

  • Strong experience in AWS Data Architecture, including S3, Glue, Athena, Redshift, Lambda, and Step Functions.

  • Experience with schema management (Avro/Protobuf, Schema Registry, schema evolution strategies).
  • Hands-on experience designing real-time and batch data pipelines, including CDC, partitioning, replay, and idempotency.
  • Strong understanding of payments domain and ISO 20022 standards (PAIN, PACS, CAMT, SWIFT/file-based systems).
  • Proven experience implementing data governance frameworks (data ownership, quality SLAs, lineage, retention).
  • Experience building observability and monitoring frameworks with actionable alerts and dashboards.
  • Strong software engineering practices, including CI/CD (GitLab/Jenkins), automated testing, and secure coding.
  • Experience with Infrastructure as Code (Terraform).
  • Strong understanding of logical and physical data modelling, including ERDs, normalization (up to BCNF), and denormalization strategies.
  • Experience designing analytical and transactional data models (star schema, Data Vault, OLTP vs OLAP patterns).
  • Knowledge of CQRS and event sourcing, including when to apply these patterns effectively.
  • Expertise in Event-Driven Architecture (EDA), including pub/sub, orchestration, idempotency, and delivery guarantees.
  • Strong grasp of domain-driven design principles, including bounded contexts, aggregates, and anti-corruption layers.
  • Experience defining and managing domain events and contracts, including versioning, replay, and schema evolution.
