• Collaborate closely with different teams (Operations, Marketing, Tech, Customer Support…) to deeply understand their workflows, identify friction points, and turn real needs into technical solutions.
• Design, prototype, and build internal tools or MVPs that optimize processes or enhance customer experience from internal dashboards to smart process automations.
• Use your backend development skills (in Python, JavaScript/Node, or Ruby) to build services, automate tasks, integrate with internal/external APIs, and work with SQL.
• Identify opportunities, pitch and test ideas fast, and evolve solutions based on real user feedback (internal or external).

• A technical background in Computer Science, Software Engineering, Telecommunications, or a related field. Whether you're wrapping up your studies or have just graduated, this is a great place to start.
• A genuine passion for solving real‑world problems whether they’re internal inefficiencies or user experience challenges, with quick, effective tech solutions.
• Curiosity and initiative: you don’t wait to be told what to build, you explore, ask questions, and identify opportunities on your own.
• Comfort with ambiguity and fast‑paced environments, priorities change fast here, and we need people who can adapt and thrive in motion.
• A willingness to fail fast, learn quickly, and improve constantly. You’re not afraid to experiment and iterate.
• Basic knowledge of web technologies, APIs, and databases (SQL), and how modern systems fit together.
• Fluent Spanish and fluent English, we work with international teams and many of our tools, documentation, and meetings are in English.
