Analyze data and user insights to support strategic decision-making.
Assist in identifying growth opportunities and improving internal processes.
Manage ad hoc projects across multiple business areas, adapting quickly to new tasks.

Highly analytical with strong problem-solving skills.
Organized, detail-oriented, and able to juggle multiple priorities.
Eager to learn, open to feedback, and comfortable working closely with senior leadership.
Excellent written and verbal communication skills (Spanish and English preferred).
Comfortable in a fast-paced, dynamic environment where flexibility is key.
Passionate about fintech, startups, and business growth.
