ApplyWhat we build at Cernexa
We help organisations connect data, agree on metrics and automate recurring tasks. Our work covers data preparation, modelling and reports that people can rely on every day.
In this role, you will learn the whole process from source to result. We are looking for a careful, curious person who wants to apply analytics fundamentals in practical projects.

- Build and improve Power BI reports, including model relationships, metrics, filters and clear visualisations.
- Write SQL queries to select, join and aggregate data.
- Compare report results with source data, investigate discrepancies and document calculation rules.
- Help turn a client question into a concrete metric and explain the result clearly.
What we ask for
- Basic Power BI skills, which may come from your studies, training or a personal project.
- Ability to work with Excel tables, formulas and pivot tables.
- SQL fundamentals: selecting data, joining tables and grouping results.
- Curiosity about what the data mean and willingness to ask when information is missing.
- Careful work: checking results and clearly documenting your assumptions.
