Telia Company

Senior Data Engineer

Are you interested in building data driven services that enable decision makers to build a sustainable society based on real-world data they can trust?

Right now, we are looking for a Senior Data Engineer to strengthen our team working on products that turn mobile network data into actionable insights.

Ready to make better happen?

Telia Company has made a strategic bet on transforming itself into a data driven company. One critical step on that transformation journey is creating business value out of data that we have. Our Data Insights team has started this journey by launching a people movement insight offering in all Telia markets. Our Data Insights product portfolio uses Telia mobile network big data, IoT data and other data sources to produce strictly anonymized insights on people movement and IoT data, creating customer value by enabling better informed business decisions in many industries.

As a Data Engineer, you will have a central role in implementing robust data pipelines and storage solutions that are capable of handling very large data sets – we currently handle over a billion datapoints per day. You will work with an international team of data scientists and data analysts, using your deep technical knowledge of distributed systems, large data warehouses and cloud architectures to discover new insights in order to support existing and Data Insights products.

The role includes, but is not limited to:

• Writing and deploying SQL queries that supports our data products hosted in Google Cloud and Microsoft Azure.
• Setting up workflows and data pipelines for new data components, including advanced SQL joins.
• Deploying infrastructure as code.
• Optimizing data processing pipelines.
• Building and maintaining our API based product interfaces.
• Investigating bugs in aggregates and deploying fixes.

Is this you?

You love being a developer and creating insights! In addition, you find it extra exciting with data and data transformation. You put a lot of pride in your code and think interaction with others is important for your own and your colleagues' development. You enjoy taking responsibility and think simplification is something to seek for. We are a good mix of people and are looking for you who are not only good at what you do, but who can add positive energy to the team.

You are located in Tallinn, where we already have presence. In addition, the Data Insights team has members in Oslo, Stockholm and Helsinki so you will be working with an international team. Data Insights is part of Division X, the emerging business division at Telia, promoting innovation and spearheading new business opportunities.

We think you recognize yourself with:

• You are a collaborator, but you also enjoy taking on independent tasks. We do not micromanage - it goes against our DNA. Therefore, it’s important you can organize your own time, be committed, and to some capacity work with limited to no supervision.
• You are flexible to learn new skills and adapt to new technologies.
• You are enthusiastic about combing through sometimes complex, structured and unstructured data.

Your experience:

• You have a good understanding of big data concepts, cloud technologies, data modeling, and can work on complex data sets, preferably using location and/or IoT sensor data.
• You have experience in cloud technologies like Google Cloud Platform, Big Query, Airflow and terraform. Knowledge of other cloud stacks, specifically Microsoft Azure, is a plus.
• You have solid SQL and Python skills and can write clean, performance-optimized queries.
• You have relevant experience developing and maintaining efficient ETL workflows, can navigate through complex scripts and workflows, and can make enhancements or code fixes, if needed.
• Full professional verbal and written proficiency in English is a requirement.
