The role

Every day, millions of Smart TVs running Titan OS generate a large volume of data: viewing sessions, launcher interactions, ad impressions, device telemetry and consent signals. Our data partners, such as TV manufacturers and content providers, add even more. As a Data Platform Engineer, you will help build and run the platform that turns all of this into trusted, well-governed data products for our Advertising, Content, Partner, Sales and Finance teams.

Our platform is built on AWS and Snowflake, with an Iceberg lakehouse on S3, Airflow (MWAA) for orchestration, and SQLMesh for data modelling. It is organised around data products with explicit contracts, freshness SLAs and lineage. We also maintain our own Python SDK and CLI that every data product is built on. You will work alongside senior engineers, take ownership of parts of the platform, and grow your scope as you go.

What you'll do

  • Build, operate, and improve batch and streaming ingestion pipelines that bring TV event data, partner feeds (BigQuery, PostgreSQL, ad-server and other APIs) and logs into our S3/Iceberg lakehouse and Snowflake
  • Contribute to our internal data platform SDK and CLI (Python): the shared framework, templates, local development environment and CI/CD that every data product team builds on
  • Build and maintain SQLMesh data models across our data products, from core and production datasets to analytics and reporting layers
  • Keep data reliable: data contracts, audits, freshness SLAs, lineage (OpenLineage) and metadata/cataloguing (OpenMetadata), plus monitoring and incident response when pipelines break
  • Own privacy-critical workflows, including GDPR deletion pipelines, consent data and PII handling, with full auditability and fine-grained access control through AWS Lake Formation
  • Manage data platform infrastructure as code (Terraform/Terragrunt) across AWS services such as MWAA, Glue, EMR, Kinesis, S3, Lake Formation and IAM
  • Help optimise performance and cost across Snowflake warehouses, Spark/Glue jobs and storage
  • Work with Infrastructure, Backend, Ad-Tech and business stakeholders to understand their data needs and turn them into well-designed solutions
