• Collaborate globally with distributed teams across the US, Costa Rica, UK, and India, adjusting your working schedule to support daily alignment with US East Coast stakeholders.
• Partner closely with data engineers and business leaders to develop scalable data pipelines, REST APIs, and backend services that operationalize machine learning and AI workloads.
• Apply modern software engineering and machine learning engineering (MLOps) practices to reliably move models from development into production.

• Practical expertise with software engineering best practices, including Git version control, containerization (such as Docker), automated testing, and CI/CD pipelines.
• Demonstrated willingness and flexibility to adjust working hours into the evening (typically until 18:00–19:00 CET) for real-time collaboration with US East Coast and Latin American teams.
