• Build tools with agentic capabilities to automate workflows;
• Develop APIs and endpoints for internal use and client-facing applications;
• Work closely with UI/UX designers to ensure applications meet high standards of usability and performance;
• Collaborate with the data engineering team to integrate data pipelines, databases, and harmonized datasets into applications;
• Continuously improve code quality by implementing CI/CD pipelines, performing code reviews, and following best practices for testing and debugging.

Requirements

• Bachelor’s or Master’s degree in Computer Science or a related field;
• A minimum of 6 years of professional experience in software engineering with at least 3 years working on full-stack development;
• Proven experience working in a consulting or agency environment on project-based work;
