Lead Developer, Enterprise Data Warehouse Platform (Helsinki/Oulu)

We are looking for a Lead Developer to join our Enterprise Data Warehouse Platform team and play a key role in OP Financial Group’s data platform transformation. This is a hands-on and strategic role where you will both build and lead, modernizing our data infrastructure with Azure-native services and ensuring scalable, secure, and future-proof solutions.

By joining us, you will become part of the OP Financial Group's Development and Technology organization. Our organization develops digital services and systems for our customers and our own staff. We are responsible for OP's ICT strategy, technology guidelines, architecture, common platforms, infrastructure, and the OP Group's cybersecurity. The Development and Technology area employs a total of 5,000 IT professionals from both our own team and our partners.

What is this role about?

 

As Lead Developer, you will drive the evolution of our data warehousing platform as part of OP’s wider data architecture transformation. You will work closely with the Product Owner, Enterprise Architects, and the Data Tribe’s Tech Lead to ensure compliance with architectural principles while shaping technical direction.

Your key responsibilities in a nutshell:

 

• Leading the re-engineering of EDW components using Azure-native services (e.g. Azure Container Apps, Azure Functions)
• Driving automation and CI/CD practices with GitHub Actions, Terraform, and supporting DevOps tools such as Jira and Confluence
• Overseeing the API lifecycle (design, documentation, governance) with Swagger, Apigee, and Azure API Management
• Evaluating current test automation frameworks (e.g. Robot Framework) and guiding the transition to modern solutions such as PyTest
• Supporting the transformation of the platform towards a data product–based approach
• Ensuring robust packaging, release auditing, and artifact management with Artifactory
• Providing technical direction in containerization and orchestration (Docker, Kubernetes)
• Collaborating proactively with stakeholders to align OP’s practices with enterprise standards
• Promoting data quality and governance through tools like Collibra and Soda
• Mentoring team members and fostering a culture of innovation and continuous improvement

 

This opportunity is available in Helsinki or Oulu, depending on your preference. Like the rest of OP, we work flexibly, combining office days with remote work.

• Proven experience in Azure cloud architecture and services

• Familiarity with DevOps tools and practices (Jira, Confluence)
• Knowledge of containerization and orchestration (Docker, Kubernetes)
• Experience in release management, packaging, and auditing processes
• Ability to lead cross-functional teams and communicate effectively with stakeholders

 

Nice to have:
