What You Will Be Doing

• Design and build a scalable analytics architecture capable of handling hundreds of millions of transactions

• Build and optimise an OLAP analytics stack separate from the transactional database

• Design and maintain ETL / ELT pipelines moving data from transactional systems into the analytics warehouse

• Ensure data integrity across 100M+ transaction records

• Optimise analytical queries to deliver sub-second or few-second performance

• Implement monitoring, alerting and testing across data pipelines

• Support data modelling and suggest improvements to existing database structures

• Manage supporting infrastructure across the data platform

• Work closely with ML engineers to support model training and inference

• Collaborate with technical and non-technical stakeholders to turn business questions into efficient data models

• Contribute to the long term data architecture strategy

• Help establish data governance, consistency and quality standards across the platform, * Understanding of data science concepts such as clustering or recommendation

90 Day Outcomes

Within the first 90 days you will be expected to deliver clear progress on the analytics platform.

This includes:

• Selecting the appropriate analytics warehouse based on performance, cost and scalability

• Designing and deploying ETL / ELT pipelines ingesting data from Amazon Aurora into the analytics warehouse

• Implementing monitoring and alerting across pipelines and warehouse infrastructure

• Reducing benchmark analytics query times to under 2 seconds

• Implementing a caching layer for frequently used analytical queries

• Evaluating the current data architecture and recommending improvements to support long term scale
