Role Description This is a high-impact opportunity to build and scale backend systems powering a global digital platform at the forefront of financial innovation. In this role, you will design and develop robust, high-performance services that support real-time applications and large-scale user activity. You’ll work in a fast-paced, remote-first environment where autonomy, innovation, and technical excellence are highly valued. Your contributions will directly shape the reliability, scalability, and security of mission-critical systems. - Design, develop, and maintain scalable backend services using Node.js, ensuring high performance and reliability across critical systems. - Contribute to the architecture and implementation of microservices-based platforms supporting real-time applications and APIs. - Build and deploy new features and products using agile methodologies, ensuring seamless user experiences. - Optimize backend systems for scalability, low latency, and high availability as user demand grows. - Implement strong security practices across all backend components to safeguard systems and user data. - Collaborate with cross-functional teams to integrate databases, third-party services, and blockchain-related technologies. - Continuously improve system performance, code quality, and development processes through best practices and innovation. Qualifications - Strong expertise in Node.js and JavaScript, with experience building complex backend systems. - Solid understanding of microservices architecture and distributed systems. - Experience working with databases such as MySQL and MongoDB. - Proven ability to contribute to large-scale, high-availability platforms. - Good understanding of backend security principles and best practices. - Ability to quickly learn and adapt to new technologies in a fast-evolving environment. - Strong problem-solving skills, attention to detail, and ability to work independently in a remote setup. - Nice to have: experience with blockchain integrations, Redis or message queues, and languages such as Ruby, Rust, or C++. Benefits - Fully remote work environment with flexible working hours. - Competitive compensation package. - Opportunities for continuous learning, mentorship, and career growth. - Exposure to cutting-edge technologies and innovative projects. - Collaborative, global team culture with strong knowledge-sharing practices. - Regular team-building activities and social events (virtual and in-person). - High-impact role with the opportunity to shape next-generation digital platforms. Company Description

• Design and build backend services: Architect and implement Rails-based services that are performant, scalable, and reliable, supporting high-throughput workloads and complex business logic. • Own technical delivery: Lead the technical design and implementation of complex features end-to-end — from product requirements through deployment and monitoring. • Drive system reliability: Diagnose and resolve performance bottlenecks, optimize database queries, and improve the resilience of backend systems under load. • Define technical direction: Propose and drive architectural decisions for your team’s services, evaluating tradeoffs and communicating recommendations clearly. • Mentor and elevate: Provide hands-on mentorship to Software Engineers I, II, and III on your team and in the organization through code reviews, pairing, and technical guidance. • Improve engineering practices: Define, advocate for, and improve best practices around code quality, testing, observability, and deployment for your team. • Collaborate cross-functionally: Work closely with Product Managers, Designers, QA, and other engineering teams to translate product goals into well-scoped technical solutions. • Participate in on-call rotation: Share responsibility for production incidents, contributing to root cause analysis and long-term reliability improvements.

• Discuss and research issues, bugs and new features. • Take ownership of the full development lifecycle - From planning, through designing, execution, testing to supporting in production • Be 100% hands-on - we expect technical expertise on the backend and some full stack ability and involvement in the frontend (react, typescript) to be able to be effective • Document your code and share knowledge with the team

• Traducir requerimientos funcionales y técnicos en prompts estructurados para herramientas de IA. • Utilizar IA para: Generar código backend (.NET) • Crear APIs, lógica de negocio y estructuras de datos • Validar, corregir y optimizar el código generado por IA asegurando: Calidad, Seguridad, Performance • Implementar y mantener test unitarios para asegurar confiabilidad del código. • Integrar desarrollos dentro de pipelines CI/CD. • Documentar APIs y soluciones técnicas utilizando herramientas automatizadas y asistidas por IA. • Colaborar activamente en ceremonias ágiles, aportando mejoras en productividad mediante uso de IA. • Identificar oportunidades de automatización y mejora continua en el ciclo de desarrollo. • Asegurar que el uso de IA cumpla con estándares de la organización (seguridad, privacidad, calidad).
