Devengo is a startup focused on a simple but ambitious mission: to make finance a fairer place. Founded by well-known fintech players Fernando Cabello-Astolfi and Alberto Molpeceres Their first product is a scalable and simple API that allows any company, big or small, to send and receive instant payments. A business bank account you can programmatically use in real-time.They have invested the last three years in discovering a thousand ways of making Salary Advance that don't work -to paraphrase Edison. They recently decided to collect all they have learned and pivot Devengo to laser-focus on the transformative technology they have mastered: instant payments.But their vision goes much further than this first step of democratizing access to instant payments in Europe; they will soon launch in other non-EU areas, and to make this vision a reality, they need your help. We're looking for a Senior Backend Developer to join thier team, embrace their vision, create some life-improving services for companies, and kick some asses in the process.Tus responsabilidades- Participarás de todo el ciclo de creación de software, de la exploración y diseño al desarrollo y el despliegue, haciéndote responsable de principio a fin.- Romperás grandes piezas funcionales en tareas más pequeñas, estimando de manera pragmática la duración y el alcance de las mismas.- Desarrollarás código robusto y mantenible con su correspondiente cobertura de tests.- Pasarás un tiempo cada mes ayudando al equipo de OPS para conseguir una comprensión más profunda del producto y su complejidad operacional.- Harás peer review del trabajo de tus compañeros asegurándote de aprender de ellos y de que generais un trabajo de máxima calidad.¿Cómo lo harás?Their process loosely merges practices from Kanban and Scrum with a focus on the principles of Continuous Delivery. Their workflow is currently organized in 2-weeks sprints. The Product and Tech teams work together to define the scope of the tasks and prioritize them. The work inside a sprint is broken down into tasks, using a Jira board to visualize and manage this process. Developers are then free to pick from the board what they want to work on if there is no other mate already working on it. In the daily meeting, the team meets to provide status updates, discuss blockers and explain what's coming next.Their core borrows some features from Clean Code / Hexagonal architecture and is drifting from a classic Rails backend towards a modular monolith architecture, aiming at providing the operational simplicity of a monorepo with the flexibility and isolation provided by a multi-component system. Right now we have multiple APIs to serve our native apps and web clients, with a rapidly growing amount of custom integrations. Additionally, they have connections with different financial systems to provide real-time money movements. You will help design and build APIs for their new products as we keep expanding our services.¿Cuándo trabajarás?Devengo has a flexible schedule to let team members reconcile their commitments and responsibilities with their work. There is still, however, the need for some sync time and a daily meeting just after lunch (14:00-15:00 CEST), so we ask people to be available at least between 12:00 and 16:00. That said, currently, the period where people is available ranges usually from 06:00 to 21:00.¿Dónde trabajarás?This position is 100% remote, but we are currently searching for candidates to be in a UTC ±2 hours timezone to make easy the scheduling of meetings or any other commitment that involves other members of the team.

We have quarterly offsites that involve physical meetups—they are a great moment to interact with the rest of the team!¿Qué piden?Devengo is looking for someone who has a senior perspective on software development. This perspective does not necessarily require a specific number of years but experience designing and developing APIs, knowing when to take pragmatic tradeoffs and the conviction that commercial software development is a team game where maintainability is critical.- You can communicate well in English, both orally and in writing.
