Culture and environment are at the heart of our ethos. If the above resonates with you, keep reading because we believe you could be a perfect addition to our incredible team!
Role overview
This is an infrastructure role within our Data team. You won't be writing analytics queries or building reports. You will build, run and scale the cloud infrastructure that our data platform runs on, and the tooling our data engineers use every day.
Millions of Smart TVs running Titan OS send us a constant stream of events: viewing sessions, launcher interactions, ad impressions, device telemetry and consent signals. On top of that come feeds from our data partners. All of this runs on infrastructure our team owns on AWS and Snowflake:
- Event ingestion (an HTTP collector on Kubernetes, and Kinesis)
- An S3/Iceberg lakehouse with the Glue catalog and AWS Lake Formation
- Glue and EMR for processing
- Airflow on MWAA for orchestration
- Snowflake as our warehouse
Everything is defined in Terraform/Terragrunt and deployed through GitHub Actions. As a Data Platform Engineer, you will treat the data platform as a product. Your job is to make it reliable, secure, automated and cost-efficient, so the data engineers building on it can move fast. You will work closely with our Infrastructure team and alongside senior engineers, taking ownership of parts of the platform and growing your scope as you go
Key responsibilities
- Design, provision and operate the data platform's AWS infrastructure as code (Terraform/Terragrunt): S3, Glue, EMR, Kinesis, MWAA, Lake Formation, IAM, KMS and networking
