• Asegurar que el core de préstamos sea una plataforma robusta y escalable. • Impulsar la modernización progresiva (modularización del monolito, mejoras de performance, resiliencia). • Incorporar prácticas de calidad y telemetría end-to-end. • Potenciar al equipo para aumentar la velocidad de entrega sin comprometer estabilidad ni riesgo operativo. • Participar en el desarrollo, diseño y mantenimiento de aplicaciones backend para la plataforma fintech. • Colaborar con el equipo para definir y estimar los requerimientos del proyecto. • Implementar soluciones eficientes y escalables utilizando buenas prácticas de desarrollo. • Crear y mantener APIs RESTful en formato JSON para integraciones con proveedores externos (SMS, Whatsapp, Nosis, Mercado Pago, etc).

• Take ownership of backend architecture as a hands-on technical leader • Spend half your time in the code — reference implementations, critical components, refactors • Make deliberate architectural choices about how the backend should evolve • Answer architectural questions: how to evolve the monolith, set service boundaries, design for geo-distribution, and integrate AI without accumulating debt • Set backend architecture standards and make major technical decisions across teams • Guide the path from monolith toward a more modular, service-oriented backend • Develop service blueprints: API conventions, EDA patterns, testing, observability, deployment • Design cloud architecture across AWS and GCP, including multi-region and geo-distributed designs • Manage high-load, real-time systems: live class infrastructure, latency budgets, caching, capacity • Determine the best approach between buy, build, or assemble — balancing managed service use, no-code tools, or POCs

- Work with a skilled team to create software in an agile scrum setting - Support production clients with implementation, bug fixes and performances optimization. - Collaborate with product, design & business stakeholders to understand business needs, establish software requirements and implement solutions - Write quality code following proven design patterns with comprehensive tests and documentation - Actively support delivered features, owning functionality through its life cycle - Participate in code reviews, engage in tech skill development and knowledge sharing
