Principal Data Engineer (AWS)

As a Principal Engineer, you will shape the engineering direction for platforms that enable data consumption, model execution and deployment at scale, while meeting strong governance and control requirements.

See yourself in the team

You’ll be part of the Capital Provisioning Modelling Crew, working across credit risk modelling, data and platform engineering.

The crew focuses on:

• Consuming trusted data from enterprise data marketplace
• Enabling model execution and orchestration at scale
• Supporting SageMaker-based model deployment and ML workloads
• Driving modernisation and decommissioning of legacy and sandpit environments
• Delivering efficiencies into the framework and tools that can help deliver the models in a safe, sound, and secure way
• Embedding controls, lineage and auditability by design

As a Principal Engineer, you will

• Define and drive platform strategy for capital provisioning modelling
• Architect and build cloud-native platforms (AWS) supporting model and data workloads
• Provide thought leadership and contributes to the design of technical solutions and consumption patterns, including data security and data management.
• Design solutions that consume and operationalise enterprise data marketplace assets
• Lead engineering patterns for model and ML deployment, orchestration and monitoring
• Drive migration from legacy platforms to strategic, governed environments
• Ensure alignment with Model Risk Management, regulatory and audit requirements, including:

• Data lineage and traceability
• Reproducibility of model outputs
• Strong controls and validation

• Partner with modelling teams to productionise models and improve reliability and performance
• Influence architecture and engineering decisions across crews and domains
• Set and uplift engineering standards and practices
• Mentor engineers and contribute to a high-performing engineering culture

We’re interested in hearing from people who

• Have strong experience building cloud-native data and model platforms at scale
• Have experience productionising models or ML workloads
• Have experience in building frameworks and tools that can significantly improve engineering productivity
• Understand data integrity, reconciliation, and accuracy in financial systems
• Can influence across teams and align stakeholders on technical direction
• Have a natural drive to educate, communicate, and coordinate with different internal stakeholders and consultants.
• Are comfortable balancing technical debt with long-term platform strategy

Technical experience

We use a broad range of tools, languages, and frameworks. We do not expect you to know them all but experience or exposure with some of these, or a willing to learn these skillsets (or equivalents) will set you up for success in this team!

• AWS (S3, EMR, Glue, Lambda, Redshift, SageMaker or similar)
• Snowflake or enterprise data platforms / data marketplace patterns
• Python, PySpark and distributed data processing
• Batch and streaming data pipelines (e.g. Airflow, Spark, Glue)
• CI/CD, automated testing and infrastructure-as-code
• Observability, monitoring and reliability practices
• Strong SQL and relational database experience
