• Proficiency with version control (Git)
• Flexibility to quickly adapt to changing priorities within a very dynamic startup environment
• Effective and flexible communication skills, including the ability to translate technical details into business and commercial objectives, and vice versa
• A proactive communication style – you’re not afraid to challenge the status quo and articulate your vision to both technical and non-technical stakeholders
• Self-driven and detail-oriented mindset while working with data
• Nice-to-have: hands-on experience with AWS data components, like Iceberg, S3, Glue and Redshift for transformation, ingestion and storage of data
• Nice-to-have: experience AI-driven data structures development

Tasks

• Own the full lifecycle of BI development: from gathering and challenging business requirements to solution design, deployment, and fostering end-user adoption
