Overview

About Félix: we are building the financial ecosystem for Latin immigrants in the U.S., starting with a revolution in remittances. Our core product is an AI-powered chatbot built on WhatsApp, allowing users to send money home as easily as sending a text message. We leverage cutting-edge technology like AI, blockchain, and stablecoins to make cross-border payments faster, more affordable, and more accessible than ever before.

We are a hyper-growth Series B company, backed by over $100 million in funding from top-tier global investors. The Félix founders were selected as “Endeavour Entrepreneurs” and recipients of the CrossTech Fintech Startups Award. We are a team of high-performers united by a shared goal: empowering our customers. We are all owners of Félix, driven by a bias for action and an experimentation mindset to get things done with urgency and focus.

• Infrastructure: Design and manage infrastructure capable of handling millions of daily requests with real-time messaging capabilities.
• Web Development: Utilize web development technologies to build user-facing applications that integrate seamlessly with our chat-based solutions.
• Cloud Integration: Develop backend services using established industry standards and Google Cloud services.
• Collaboration & Mentorship: Foster the growth of junior developers through mentorship and best practice implementation, while collaborating closely with cross-functional teams including product, UX/UI, and business units.
• Continuous Improvement: Leverage customer feedback and analytics to iterate and improve our conversational experience, ensuring that our chatbots remain effective and user-friendly.
• Proficiency in English at an Upper-Intermediate level or higher is required.
