Descripción del empleo

We're looking for aJunior React Developer to join our multicultural team and be part of the full development cycle of web and mobile apps: including understanding business needs, designing solutions for specific problems, and developing the product.

What are the main responsibilities of this role?

• Deliver well-designed and high-quality code, with automated tests.
• Navigate ambiguity with strong technical judgment: evaluate tradeoffs, break down unclear requirements, and take ownership of the outcome regardless of how much of it was AI-assisted.
• Engage with the product, not just the code: understand the business problem behind each requirement, bring technical judgment into early product definition, and connect technical decisions to product and client value.
• Participate in the overall management of the project (planning and review calls, board and story-map maintenance, etc).
• Ensure the development of high-quality code across the company.
• Write meaningful code reviews, including critical review of AI-generated code.
• Collaborate with internal initiatives.
• Encourage project and company technical improvement.
• Assist team members and generate meaningful discussions during disagreements.
• Execute the right level of documentation for the project.

Which skills and experience do we envision for this role?

• Software experience from degree studies.
• +1 year of experience in the IT field.
• Experience with React, including functional components, hooks, and state management, and familiarity with Next.js.
• Experience with HTML, CSS, JavaScript and TypeScript.
• Basic knowledge of testing concepts and unit testing.
• Experience with Git and version control workflows.
• Advanced English skills, both written and spoken.
• Experience working with agile methodologies and within an agile environment.
• Experience working with CI/CD pipelines (Continuous Integration and Continuous Delivery)
• Hands‑on experience using AI development tools (such as Cursor or Claude Code) as a core part of the development workflow, going beyond single-prompt assistance into agentic workflows.
• Comfort engaging directly with product/client stakeholders to understand what's driving a requirement, not just what it asks for.

Join our team and enjoy:

• Access to Certifications, and a Mentorship Program for your professional growth.
• Learning Bonus.
• Opportunities to organize cross‑functional initiatives and receive 360 Feedback to improve your skills continuously.
• The flexibility to work remotely or from our offices in Montevideo or Buenos Aires with a flexible schedule and a Workation program available after the first year with the company.
