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 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
Own the platform’s CI/CD and developer tooling: GitHub Actions workflows, OIDC-based deployments, package publishing (CodeArtifact), local development environments, and our internal Python SDK/CLI that every data product is built on
Operate and scale our orchestration (Airflow on MWAA) and ingestion services: upgrades, environment management, capacity, reliability
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 Snowflake as infrastructure: roles and access control, warehouses, integrations with S3/Iceberg, service accounts and secrets
Build observability for the platform: monitoring, alerting, logging, lineage and metadata tooling (OpenLineage, OpenMetadata), plus taking part in incident response
Track and optimise cloud costs across AWS and Snowflake (storage, compute, warehouses, job sizing)
Apply security best practices: least-privilege IAM, encryption, secrets management and audit trails, in line with our ISMS
Work with Infrastructure, Backend and the data engineers to improve platform standard and remove friction from their workflows

What makes you a great fit

3+ years of experience in platform, infrastructure, DevOps, or cloud engineering, ideally supporting data workloads
Strong hands-on experience with AWS, especially IAM, S3, VPC/networking, KMS and Secrets Manager, plus at least some of Glue, EMR, Kinesis, MWAA, or Lake Formation
Solid experience with Terraform (Terragrunt a plus) and managing infrastructure across multiple environments and accounts
Experience building CI/CD pipelines (GitHub Actions or similar)
Good Python skills for automation, tooling and internal libraries; comfortable with Bash
Experience with containers (Docker) and some exposure to Kubernetes
Experience running or supporting Apache Airflow (MWAA a plus) or similar orchestrators
Familiarity with data platform components (Snowflake or another cloud warehouse, Spark, Iceberg/Parquet), mainly from the angle of deploying, securing and operating them
An operational mindset: monitoring, alerting, troubleshooting and on-call
Strong communicator and fluent in English

Nice to have

Hands-on experience with AWS Lake Formation, Snowflake administration or other data access governance tools
Experience with GDPR, consent management (e.g. OneTrust) and PII deletion workflows
Experience with observability tools (Datadog, CloudWatch) and FinOps practices
Experience with OpenLineage/Marquez or OpenMetadata
Some exposure to SQL transformation frameworks (SQLMesh or dbt), so you understand what our data engineers need
Go experience, for working on our event ingestion services
Experience in AdTech, CTV/OTT or streaming media
Interest in AI-assisted engineering (LLM tooling, MCP integrations)

This role is a good fit if you enjoy building the platform more than the pipelines on it: infrastructure as code, automation, security and reliability. If you mainly enjoy writing SQL transformations and data models, this probably isn’t the right role.

Reasons to apply

Centrally located office in the heart of Barcelona, with public transportation nearby
Competitive compensation
Private health insurance
Friendly, diverse, and international work environment
Opportunity to work outside of your comfort zone and develop professionally in an exciting and fast-growing CTV industry.
Change the future of TV! A unique opportunity to join a well-funded, high-growth company in the early stages to help shape a product/business that will impact millions.
