• Engineer and optimize high-performance Ruby systems that handle billions of financial transactions, solving deep scaling, data, and code-quality challenges. • Design and develop scalable backend systems that process billions of financial transactions. • Provide technical direction across projects and collaborate with product and engineering leads to define priorities and architecture. • Own project delivery: from design and implementation to performance and reliability in production. • Refactor and modernize core Ruby systems to improve maintainability, readability, and speed. • Mentor other engineers through technical reviews, design discussions, and clear documentation.

• Coordinar con el resto del equipo durante las reuniones diarias. • Dar soporte durante la fase de golive de nuevos entornos. • Crear nuevos entornos para clientes y dar soporte during las diferentes fases. • Llevar el día a día de las operaciones de clientes y sus infraestructuras en la nube. • Seguimiento proactivo y reactivo a las incidencias que puedan ocurrir. • Trabajar con los diferentes proveedores de infraestructura como servicio. • Mentorizar a los juniors para que lleguen algún día a ser seniors. • Liderar reuniones con clientes nacionales e internacionales de una manera autónoma.

• Take ownership of major frontend initiatives, help lead complex technical projects, and work directly with leadership to define the future of our platform. • Help us address technical debt, a complete revamp of our client interfaces, build and maintain our in-house design systems, and build scalable solutions for one of our product verticals. • Roughly 70% of your time — front-end / back-office revamp: Own the revamp of key back-office pages and features within the Booking scope (list and detail views, member profiles, establishment pages, teacher tools…) • Implement interfaces from high-fidelity prototypes delivered by our dedicated designer • Write clean, tested React (TypeScript) code aligned with our internal design system • Collaborate with internal engineers to ensure long-term maintainability • Roughly 30% of your time — backend support for the revamp: Evolve and adapt the backend logic that powers the revamped front-end features (APIs, data models, business rules) • Ensure the back-office pages you're rebuilding are fully supported end-to-end — not just visually, but functionally • Work closely with internal backend engineers to align on contracts, flag dependencies early, and unblock front-end delivery
