Data Engineer – Mid Level Greece

Role type: Permanent

Location: Greece

Data Engineer required to join our Satalia team in Greece

As an organisation, we push the boundaries of data science, optimisation and artificial intelligence to solve the most complex problems in the industry. Satalia, a WPP company is a community of individuals devoted to working on diverse and challenging projects, allowing you to flex your technical skills whilst working with a tight-knit team of high performing colleagues.

Led by our founder and WPP Chief AI Officer Daniel Hulme, Satalia’s ambition is to become a decentralised organisation of the future. Today, this involves developing tools and processes to liberate and automate manual repetitive tasks, with a focus on freedom, transparency and trust. At the core of our thinking is an approach to wellbeing and inclusivity. We unpack human behaviour and unpick prejudice to ensure a safe and inviting environment. We offer truly flexible working and allow our employees to find the working practice that makes them most productive. At Satalia, your opinion matters and your achievements are celebrated.

The Role:

You'll build and own the pipelines and data models that turn raw data into clean, reliable, well-documented datasets — the foundation our data scientists, analysts, and AI systems build on.

Our current work includes:

• Building data pipelines — robust ETL/ELT pipelines that ingest, transform, and serve large datasets across our marketing intelligence stack.
• Data modelling and transformation — designing well-documented, tested, version- controlled data models (with dbt) that power downstream AI and BI.
• Warehouse and storage design — modelling data in our warehouse/lakehouse and relational databases, choosing the right structure for each access pattern.
• Trustworthy data — orchestration, monitoring, data quality checks, and lineage so the data people depend on is correct and dependable.
• You'll work closely with data scientists and software engineers, own your pipelines end to end, and help shape how we build data at Satalia.

What you'll be doing:

• Design, build, and maintain production data pipelines that deliver clean, reliable data to analytics, BI, and AI workflows.
• Build SQL-based data transformations and models into well-documented, tested datasets that others can trust and reuse.
• Design and operate our data warehouse/lakehouse and relational databases (e.g. PostgreSQL) for the way the data is actually used.
• Build data-quality, monitoring, and lineage into pipelines so problems are caught early.
• Contribute to pipeline infrastructure — orchestration, CI/CD, and infrastructure-as- code — for the data platform.
• Share what you know with the rest of the team.

What we want from you:

• 4+ years building and running production data pipelines and data models.
• Strong SQL and data modelling, including SQL-based transformation (dbt or similar), and solid experience with a data warehouse or lakehouse.
• Strong Python (Scala or Java a plus), with good software engineering habits — version control, testing, code review, CI/CD.
• Experience with pipeline orchestration (Airflow, Dagster, or similar).
• Hands-on experience with a cloud platform (GCP or AWS).
• Clear communication — you can write a short design doc that's useful to both product managers and engineers.

Nice to have:

• Distributed data processing at scale (Apache Spark or similar).
• Containers (Docker) and infrastructure-as-code (Terraform).
• Experience with vector databases (Pinecone, Weaviate, pgvector) or graph databases (Neo4j, Neptune).
• Exposure to ML/LLM-powered data systems (RAG, embeddings, feature/serving pipelines).
• Event-driven or streaming data (Pub/Sub, Kafka) and real-time pipelines.

What we Offer:

• Benefits - healthcare
• Remote working - café, bedroom, beach - wherever works;
• Truly flexible working hours - school pick up, volunteering, gym;
• Generous Leave – inline with Greek Labour Law
• Impactful projects - focus on bringing meaningful social and environmental change;
• People oriented culture - wellbeing is a priority, as is being a nice person;
• Transparent and open culture - you will be heard;
• Development - focus on bringing the best out of each other;
