What you’ll be doing…

As a Data & ML Platform Lead, you will lead the team responsible for building and operating the infrastructure at the core of Curve’s business. You’ll own the platform supporting streaming and batch data ingestion, reverse-ETL, real-time decisioning for fraud and financial crime, and the ML and agentic AI capabilities increasingly used across the organisation. This is a hands-on platform engineering role where you’ll lead and develop a multidisciplinary team while remaining closely involved in the most complex architectural challenges.

You’ll own the design and reliability of Kafka-based decisioning services, data pipelines, orchestration, feature stores and underlying cloud infrastructure, ensuring the platform operates to bank-grade standards of reliability, auditability and scale as Curve integrates into Lloyds Banking Group.

Proven experience designing and operating production systems on GCP, including technologies such as BigQuery, Managed Airflow, Cloud Run and Dataflow, or equivalent cloud infrastructure

Strong programming ability in Python and experience with at least one systems language, ideally Go

Experience building and operating real-time services as well as batch and streaming data pipelines

Experience with Terraform, Kubernetes and infrastructure as code

Strong experience operating orchestration platforms such as Airflow reliably in production

Experience deploying and operating ML systems in production, including feature stores, model serving or ML-driven decisioning systems

Experience designing reliable, observable platforms with clear SLAs, monitoring, alerting, load testing and capacity planning

Strong understanding of operating technology within regulated environments, including audit trails, control evidencing, change governance and production systems with compliance implications

Experience designing safe deployment approaches including feature flags, shadow modes, staged rollouts and reversible releases

A track record of automating manual operational processes and building systems that are scalable, reliable and maintainable

Strong leadership skills with the ability to set technical direction, delegate effectively and develop engineers into owners of the systems they operate

And it would be great if you had any of the following...

Experience building or operating LLM and agentic AI workflows in production

Experience within financial crime, fraud, credit or risk decisioning environments

Experience integrating technology platforms with large banking organisations or banking vendor ecosystems

Hands-on experience with Feast
