Job description

We’re looking for a BI Developer to join our team and support the implementation, development, and maintenance of reporting solutions for clients across various industries.

You’ll work on end-to-end BI projects – from gathering business requirements and designing data models, through building data integration processes (Power BI or more often in Snowflake/Azure), to delivering clear, interactive dashboards that drive real business decisions.


Your responsibilities:

  • Design and develop reports and dashboards in Power BI Desktop and Service.

  • Build interactive, user-friendly visualizations aligned with UX/UI best practices.

  • Develop data models and create DAX measures and calculations.

  • Integrate and transform data from multiple sources (databases, Excel, SharePoint, API, CSV, OData, etc.).

  • Publish and maintain reports in Power BI Service – workspaces, permissions, refresh schedules.

  • Implement and manage Row-Level Security (RLS).

  • Collaborate with analysts, architects, and business stakeholders to define requirements and design effective BI solutions.

  • Participate in consulting-style projects, proactively suggesting improvements to reporting, automation, and data processes.


We are looking for you, if you have:

  • Strong hands-on experience with Power BI Desktop (visualizations, dashboards, data storytelling).

  • Solid understanding of data modeling principles and SQL (queries, views).

  • Proficiency in DAX for building efficient calculations and measures.

  • Experience with Power BI Service administration and maintenance.

  • Knowledge of ETL / ELT processes (e.g., Power Query, Dataflows, Azure Data Factory, or similar).

  • Ability to work with multiple and diverse data sources.

  • Strong communication skills and ability to translate business needs into technical solutions.

  • Attention to detail, quality, and report performance.

  • Team-oriented mindset and willingness to collaborate.

  • Proactive attitude and focus on delivering business value through data.

  • Curiosity and initiative – we expect active engagement in improving reporting and automation processes.


Nice to have:

  • Familiarity with Azure Data Platform (Azure SQL, Synapse, Data Lake).

  • Experience with Python for data analysis or integration.

  • Working knowledge of Agile / Scrum methodologies.

  • Microsoft certifications (e.g., PL-300, DA-100).


We offer:

  • Participation in interesting and challenging projects

  • Flexible working hours

  • A great, non-corporate atmosphere

  • Stable employment conditions (contract of employment or B2B contract)

  • Opportunities for development and promotion

  • Package of benefits

  • Remote work


We reserve the right to contact the selected candidates.
