Senior Data Engineer (Snowflake/dbt/AWS) - Portugal Full Remote

Senior Data Engineer (Snowflake/dbt/AWS) - Portugal Full Remote
ABOUT THE OPPORTUNITY
We’re hiring two Senior Data Engineers to join an international, people-first software engineering company known for high-performance systems used by millions of people worldwide. This is a hands-on role for someone who likes to build, own production systems end to end, and share what they know. You’ll work directly with senior leadership and client teams, in a culture built on empathy, self-organization and the courage to take risks. AI-assisted engineering is encouraged here, as long as it comes with solid engineering judgment.
PROJECT & CONTEXT
You’ll join a data project for a leading retail client, building and running the pipelines and platforms that move data from source systems to the warehouse, on production systems where it really matters. Your scope includes:

• Building and running batch and streaming ingestion pipelines from databases, event streams and third-party APIs

• Owning storage architecture across lake, lakehouse and warehouse, with a focus on partitioning, cost and query performance

• Keeping pipelines observable and restartable through orchestration, automated testing, alerting and clean recovery

• Applying software engineering practices to data: infrastructure as code, CI/CD, code reviews and version control

• Defining data contracts with producing teams to control schema drift, and managing access, retention and lineage

• Writing documentation that outlasts the engagement

Fully remote from Portugal, with occasional national or international travel (0–15%) depending on project needs.
WHAT WE’RE LOOKING FOR (Required)

• 5+ years of experience as a Data Engineer, with pipelines built and run in production

• Advanced, production-grade SQL and Python 3

• Extensive experience with ETL/ELT processes and CI/CD for data workloads

• Hands-on experience with dbt

• Experience with orchestration tools such as Apache Airflow, Azure Data Factory or Dagster

• Extensive experience with Snowflake and Terraform

• Strong understanding of data modelling methodologies: Kimball, Inmon and Data Vault

• Production experience with AWS

• Use of AI tooling in daily work, with the review discipline to check what it generates before it ships

• Fluent English (spoken and written), comfortable working directly with client teams

NICE TO HAVE (Preferred)

• Experience with a second cloud provider (GCP or Azure)

• Spark/PySpark at scale and Databricks

• Streaming and pub/sub brokers: Kafka, Kinesis, Pub/Sub or MQTT

• Open table and file formats: Parquet, Apache Iceberg, Delta Lake

• Docker, Kubernetes and GitHub Actions

• Data quality frameworks in production: Great Expectations, Soda or Monte Carlo

• AI data infrastructure: embedding pipelines, vector stores, feature stores

• NoSQL stores (e.g. MongoDB) and marketing data sources (Google Ads, Meta, CRM APIs)

• A cost engineering mindset: making pipelines cheaper and quantifying the savings

• Experience in regulated environments (GDPR, access control, auditable lineage)

Compensation: €2,700 – €3200/month net, depending on experience and seniority level.
