Full Time Data Engineer

At idealo, data guides every decision. To support this, we offer a compliant, scalable, and cost-efficient data platform within the AWS ecosystem – enabling insights and establishing company-wide standards.
As we shape the long-term vision of our data engineering team, we are currently looking for support in our B2C subteam – a small but crucial team of three engineers working on high-impact topics like compliance and product data quality.
This is an exciting time to join: you’ll become part of a team that’s growing together while setting the foundation for technical excellence, shared ownership, and impactful delivery – in an environment that values diverse perspectives, mutual support, and continuous learning.

The position as Data Engineer (m|f|d) is advertised as full-time or part-time.

You will be part of the B2C subteam – one of three subteams in our 11-person data engineering unit – where you design and implement new processes that enrich our data and ensure high quality for downstream consumers.
Working closely across all three cross-functional subteams, each aligned with a key business domain, you will take end-to-end ownership of (data) products and help shape data into a strategic asset at idealo.
In this role, you will be jointly responsible for designing, developing, implementing, and maintaining (data) products – including automated filtering of data streams, error detection, and plausibility checks.
As part of our supporting functions, we deliver reliable business KPIs and actionable insights that drive key decisions and create real business impact.
Data correctness is a top priority at idealo – and we play a central role in achieving it. We enable technical and operational solutions that ensure data quality all the way to the end customer.
We believe in ownership: you’ll take responsibility across the entire software engineering workflow and act as an advocate for (data) product quality – both within and beyond your immediate team. You bring at least 3-4 years of hands-on experience in data engineering or a related field – and are ready to grow into more ownership, technical maturity, and collaborative responsibility.
You have a strong foundation in data structures and algorithms.
You bring ideas from all areas, including distributed computing, large-scale system design, security, networking and data storage.
Solid programming skills in languages such as Python, Java or similar.
Strong knowledge in SQL, relational databases, Apache Spark or comparable technologies.
Familiarity with data privacy regulations (e.g., GDPR) and best practices for ensuring compliance when handling sensitive data.

We offer you 30 days of vacation. You can "buy" an additional 15 days every year by converting your salary and it's seen as a positive thing.
You want to further your education? We take your personal development goals seriously and, in addition to our idealo Learning Hub, eLearning offerings (e.g., Udemy), coaching & mediation, we also offer you the opportunity to benefit individually from additional learning and development budget.
