We’re renewing our marketing automation to empower truly personalized, automated omnichannel messaging across every customer touchpoint.
Anchored by a Snowflake-based data platform, this transformation will modernize our marketing operations, accelerate experimentation, and create a scalable engine for business growth—while simplifying the stack and governance.
Are you the Data Engineer to make it happen?
About the role:
As our (Senior) Data Engineer for Martech, you’ll turn raw customer, store, and receipt data into trusted, reusable semantic models that fuel segmentation, real-time triggers, and measurable outcomes. And you’ll provide the ability for the business to understand and analyse those outcomes — helping us deliver a best-in-class omnichannel customer experience.
You play a key role in ensuring that data is readily available for our modern analytics and AI solutions, presenting it in a format these applications can truly understand. By doing so, you act as an enabler and accelerator for the efficient and high-quality utilization and use of data, making it easier for our business to harness its full potential in innovative ways.
This role will start working with the Martech transformation project team – developing data pipelines but also drawing the big picture -- future-proofing the architecture for 2026–2030 and beyond.
Going forward, there will be an opportunity to develop other areas of, as well as working with tech features like Snowflake AI services.
You will be part of Kesko’s central Data & Analytics Platforms team, collaborating with expert & supportive colleagues in the platforms as well as other domain-focused data engineers. Your daily work will be with Marketing Technology IT and business teams.
We are working in a hybrid workplace model where we combine office days at K-Kampus and remote work to best suit both the role and the team. Come join our professional team and start building your own kind of career in K group!
Your main responsibilities:
- Designing, building and optimizing data pipelines and models: Use Snowflake, dbt, and other tools to create scalable data integrations to and from the Marketing Automation tool
- Collaboration and consulting: Work closely with domain experts to translate business needs into data solutions, advise on best practices, and support others in using the data platform.
- Implementing data management & governance: Establish sound data practices – from documenting lineage and using data catalogues to setting up quality checks – to ensure we trust and understand our data.
- Continuous improvement: Keep an eye on new tech and techniques. Continuously improve performance, cost-efficiency, and reliability of our data solutions.
To succeed in this role, you should have:
- Strong experience in data engineering with modern cloud data platforms. Hands-on expertise in Snowflake is required. Proficiency with dbt for data transformations and SQL for data analysis/manipulation. You can write efficient SQL and have solid data modelling skills. Experience with version control (Git) and CI/CD pipelines in a data context.
- Interest in Marketing: background in Marketing Automation tools (like Braze and Salesforce) is a bonus, but an understanding of the business processes and the data involved in them is needed. You will be helping to guide the future.
- Background in data warehousing/ETL: You have designed or maintained data pipelines. Experience with traditional SQL Server-based ETL or integration is beneficial, as it helps in understanding our legacy environment.
- Data management mindset: Familiarity with data cataloging, lineage tools, or overall data governance frameworks. You care about documentation and data quality.
- Communication: Excellent teamwork and communication skills. Fluency in English is required (our working language). Finnish language skills are beneficial but not necessary – our team is international. You can clearly explain complex data topics to both technical and non-technical colleagues.
- Self-driven & proactive attitude: You take initiative to improve things and aren’t afraid to suggest new ideas. You are solution-oriented and able to work independently when needed but also know when to ask for help or input.
- Please note that the role is in Finland and you will need the existing right to work here. Kesko is unable to sponsor work permits or visas.
