Reaktor's award-winning tech community is looking for a Senior Data Engineer to join us in Helsinki or Tampere.
If you thrive on working with data, enjoy uncovering actionable insights from unstructured datasets, and are driven to consistently deliver real value to customers, you might be exactly who we're looking for.
At its core, Reaktor is a technology company that helps ambitious organizations become digital leaders. From premium software development to digital transformation, our global community of experts do it all – here are some of our most recent digital ventures to give you an idea of what that means.
As a Senior Data Engineer at Reaktor, you’ll design and build scalable architectures behind data-intensive applications.
Your daily tasks include:
Designing and developing scalable data pipelines (ETL/ELT) in both batch and stream processing settings.
Working on infrastructure, integrations and APIs for storing, transforming and delivering data to end users.
Working together with our clients and domain experts to figure out their data needs.
Collaborating with data scientists, machine learning engineers and designers to design end-to-end data products.
On your typical day at work you might be creating and building: an end-to-end data pipeline for gathering impression data and serving content recommendations for a media streaming platform; a semantic search engine for large amounts of textual data; a data lake with numerous sources of financial data; or a platform and data pipelines for running ML models and integrating results to different applications.
To thrive in this position, you’ll need:
Experience in hands-on data engineering projects.
A background in working with databases and SQL (such as PostgreSQL, DynamoDB, Redshift, BigQuery).
Experience in data platforms, data lakes or data warehouses (such as Databricks, Snowflake).
A solid programming foundation in Python (required), with additional experience in other languages such as Java or TypeScript being a plus. Proficiency in data-related libraries like PySpark and Pandas.
Experience in at least one cloud provider (AWS, Azure, GCP).
Understanding of infrastructure-as-code practices (such as Terraform, CloudFormation, CDK).
Consulting skills i.e. good communication skills and the ability to work with clients to figure out their data needs.
Fluency in English both written and spoken. Finnish is seen as an advantage.
General knowledge of modern data science and business intelligence tools and frameworks is seen as a plus.
Experience in data architectures and data modelling is a plus

Our experts are the foundation of our high-quality client work, and your wellbeing is always our utmost priority. You’ll be supported with internal training and events, development discussions, various hobby clubs, and an altogether comprehensive benefit package.
While working at Reaktor, we’ll provide you with:
The ability to impact how you work. Together with the client, your team chooses the approach, technologies, and methodologies you think will work best in any given situation
A community with as much support as your heart desires
A team that’s not only experienced but considerate as well – they all want you to succeed
A sustainable work-life balance and support for your daily life outside of work. (e.g., free moving day, Reaktor car share, sick child care services, office space to use for your private events, etc.)
An opportunity to grow as a professional. In addition to the day-to-day work, we offer internal training courses, community events, and 15-minute coffee breaks to discuss hot topics in tech and design
A possibility to take part in more extended academy-like studies like Cloud Academy
300+ hobby clubs, from winter swimming and running to knitting and archery, that bring people together outside of (and sometimes inside) office hours. Many of these are supported by Reaktor
