BI Data Analyst

Place of work: Grösslingová, Bratislava, Slovakia (Job with occasional home office)

Contract type: full-time

Start date: Upon Agreement

What will you be in charge of?

As a BI Data Analyst, you'd be part of the team building out reporting for a fast-moving e-commerce business operating across 21 European markets – working with our data warehouse to turn business questions into reports people actually rely on, with a strong focus on the financial side of the business.

• You'd design and build Power BI reports – from data model to DAX logic to the final visual – working closely with our database and BI specialists along the way.
• You'd work directly with Finance and other business stakeholders, helping them shape a rough idea into a report that actually answers their question – margins, costs and P&L included.
• You'd get comfortable spotting trends, inconsistencies and manual work worth automating, and suggest where reporting could do more.
• You'd take care of data quality and validation on the reports you build, so people can trust the numbers without double-checking them.
• You'd help present findings in business reviews, explaining what the data shows – and what it means financially – in a way that lands with people who don't work with Power BI day to day.
• You'd grow into a go-to person for Power BI, DAX and Power Query on the team, with support from more senior colleagues along the way.

What we are looking for:  

• Strong hands-on experience with Power BI, including confident use of DAX, data modelling and Power Query
• Good SQL skills and the confidence to analyse large datasets, plus solid working knowledge of Excel
• A strong analytical and problem-solving mindset
• Experience working directly with business stakeholders
• Ability to translate business questions into reporting solutions
• High attention to data quality and validation
• Ability to explain analytical findings clearly to non-technical audiences
• A finance background, with an understanding of P&L, margins and cost structures
• Fluent English and Slovak, since you'll be working closely with both local and international colleagues

Nice-to-have

• Experience with Microsoft Fabric
• Experience working in e-commerce
• Familiarity with AI tools (e.g. ChatGPT, Copilot, Claude) to improve productivity
• Basic Python skills

Personality prerequisites and skills

• • Ownership and follow-through, without needing constant check-ins
