📋 Description
- • Join Pragmatike Soluciones Tecnológicas S.L. as a Lead Fullstack Engineer, a pivotal role in shaping the future of an innovative AI and trading startup. This is a unique opportunity to work remotely from anywhere, contributing to the development of a groundbreaking platform that unifies all trading dimensions under a single AI-powered layer. Our client is revolutionizing algorithmic trading by deploying autonomous AI agents that operate continuously, eliminating emotional bias and optimizing trade execution. During its beta phase, the platform has already successfully managed over $500,000 in assets and is poised for rapid scaling to accommodate thousands of agents across diverse trading venues.
- • As a Senior Full Stack Engineer, you will be instrumental in building and scaling the product experience and core application layer. Your contributions will be crucial as the platform transitions from its early traction phase to achieving institutional-grade scale. This role demands a proactive and experienced engineer who can architect, develop, and deploy robust, scalable web applications.
- • Your primary responsibilities will include designing and building production-ready web applications utilizing modern frontend frameworks such as React and Next.js. You will be responsible for developing sophisticated backend services and APIs powered by Node.js, ensuring seamless integration and high performance. A key aspect of this role involves architecting end-to-end features, spanning the entire technology stack from frontend user interfaces to backend logic and database management.
- • You will play a critical role in building real-time dashboards that provide essential insights into trading performance, agent monitoring, and overall platform analytics. This includes implementing secure authentication, authorization, and role-based access control systems to safeguard user data and platform integrity. Furthermore, you will focus on optimizing frontend performance, enhancing the user experience (UX), and refining state management for a smooth and responsive application.
- • Collaboration is key in this dynamic environment. You will work closely with AI, backend, and infrastructure engineers to seamlessly integrate sophisticated trading agents and execution systems. Ensuring the highest standards of code quality will be paramount, achieved through rigorous testing, implementing robust CI/CD pipelines, and adhering to best engineering practices. You will also actively contribute to architectural decisions, influencing the long-term scalability and strategic direction of the product.
- • This role offers a high degree of ownership and the chance to significantly shape product direction within a fast-paced, startup environment. You will be at the forefront of innovation, working at the intersection of artificial intelligence, sophisticated trading strategies, and scalable web architecture. The opportunity to build the product layer of an AI-first trading platform, with direct impact on user experience for real-money trading systems, is unparalleled. You will gain exposure to both the volatile world of crypto and the established landscape of traditional financial markets, backed by a top-tier institutional investor. This is a career-pivoting role for an engineer seeking significant influence and growth.
