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

Diversity, equity, and inclusion

Together, we are committed to making Reaktor an environment that embraces and values all of our employees for the whole of who they are. We encourage applicants from all backgrounds to apply, knowing that studies show that members of underrepresented communities don’t apply for jobs unless they fully satisfy all of the requirements. If you're thinking twice about applying for this reason, we invite you to send us your application anyway. You could be just the person we're looking for.
