* Design, build, and maintain optimisation-related BI dashboards
REQUIREMENTS:
* 5+ years in data analysis or BI—ideally within network security, cloud
operations, or a SOC environment
* Strong proficiency with SQL (BigQuery dialect), including complex joins,
window functions, CTEs, and performance tuning
* Comfortable building and maintaining ETL pipelines (Airflow, Bash, Python)
* Hands-on with data visualization tools (Tableau, Power BI, Looker, Grafana)
* Good understanding of data lake and lakehouse concepts, partitioning and
clustering
* Familiarity with data catalog/governance platforms (Apache Atlas, DataHub)
and Git for schema/version control
* Skilled in data profiling, cleansing, and enrichment techniques to ensure
high-quality inputs
* Strong problem-solving mindset, attention to detail
* Good communication skills—able to translate complex data into actionable
business insights in English

environment
* Growth focus: Take on large-scale projects with a global impact and expand
your expertise
* Tailored learning: Boost your skills with internal events (meetups,
conferences, workshops), Udemy access, language courses, and company-paid
certifications
* Endless opportunities: Explore diverse domains through internal mobility,
finding the best fit to gain hands-on experience with cutting-edge
technologies
* Flexibility: Enjoy radical flexibility — work remotely or from an office,
your choice
* Care: We’ve got you covered with company-paid medical insurance, mental
health support, and financial & legal consultations
