• Solid understanding of Agile methodologies and experience delivering features in two‑week sprint cycles.
• Excellent communication skills, with the ability to convey technical concepts to non‑technical stakeholders.
• Fluency in English (both written and spoken) is required; Spanish proficiency is a plus.

Preferred Qualifications

• Advanced degree in Computer Science, Data Engineering, Statistics, or a related field.
• Experience with cloud platforms (AWS, GCP, or Azure) and managed services such as EMR, Databricks, or Redshift.
• Familiarity with data visualization tools (Tableau, Power BI, Looker) to support end‑user reporting.
• Knowledge of machine‑learning pipelines and ability to collaborate with data‑science teams on model deployment.
• Certifications in Big Data, Cloud Architecture, or Agile Project Management.
