• Proven track record of building robust, automated ETL/ELT pipelines.
• Familiarity with distributed systems and handling large-scale data (millions of rows/sec).
• Experience with data hygiene best practices: data models, versioning, reproducibility.
• Hands-on experience with cloud platforms (AWS preferred).
• Excellent problem-solving skills and a "get stuff done" attitude.

Nice to Have

• API endpoint design & maintenance.
• Prior experience in fast-scaling startups or international data systems.

• Opportunity to build and scale new data architecture from the ground up.
• Own greenfield projects and shape the data engineering roadmap
• Be part of an ambitious, global expansion journey (Europe, U.S.).
