Empowering the world starts with living our values and empowering our team. As a quickly growing company focused on helping people live healthier and happier lives, we ensure that our team members have what they need to do their best work — both in and out of the office.

We are looking for a Senior Data Engineer to join our Data & ML Platform team. 

Preferred location in Helsinki or Oulu, Finland.

You’ll join a platform team focused on Oura’s Datalake and its adjacent systems that support many internal Oura users and several production features:

What You will do:

• Building, operating and improving systems to move, process and store large amounts of data (Terabyte-Petabyte scale) leveraging tools such as: AWS Kinesis, S3, Spark / Glue, Athena, dbt, Iceberg, Snowflake, Docker, workflow engines, and more.
• Building components that support the handling of datasets, training, testing and release of new on-device and cloud-based ML models.
• Independently collaborating with different stakeholders including Data Scientists, Testing, Firmware, Hardware to define and implement improvements and new functionality.
• Supporting internal Datalake consumers in their day-to-day work.
• Writing code, mostly in Python with some additions in Typescript and SQL.
  

A special additional requirement for this position is the ability to work evenings regularly (e.g. 2-3 days a week). We have extensive collaboration with teams in the American continent, and this position is earmarked also for providing support to those teams and being involved in collaborative efforts with teams in America. The position as such however is not a support engineer role, but rather a regular data engineer role with a twist. On evening days you are free to start your workdays after midday to make sure you don't end up overextending yourself.

We would love to have You on our team, if you have:

• 4+ years of experience developing and operating production systems.
• The ability to work regularly in the evenings.
• Experience running, monitoring and debugging production systems at scale on a public cloud. We rely on AWS but experience with other cloud platforms counts too.
• Experience with programming languages such as Python and Typescript. Willingness to code in Python is required since a large part of our codebase is Python.
• Good architectural understanding of event driven architectures, workflow engines, database and data warehouse systems.
• Enjoy writing maintainable and well-tested code
• Follow common practices: version control (git), issue tracking, unit testing and agile development processes
• Generalist and pragmatic approach to development. Knowledge of various programming languages is a plus.
• Ability to build infrastructure and components following best practices such as CI/CD and infrastructure as code.
• Broad knowledge of software fundamentals, databases, warehouses and system design.
• You can write well-structured, testable and high-performance code.
• You are familiar with some of the following:
• Workflow engines, Stream processing, Spark, Athena, SQL, dbt
• You are self-motivated, proactive, and bring energy to the teams and projects you work on.
• You are driven by value creation and overall impact.
  

What makes you stand out:

• Knowledge of ML, particularly relevant if with PyTorch.

As a company we are focused on improving the way we live our lives. From the people who use our product to the team behind it, we work to empower every person to own their inner potential.
