About Us
AtFélix, we are building the indispensable financial companion for Latinos in the US. We combine an AI-powered, conversational-first interface with real-time financial infrastructure to make cross-border money movement as easy as sending a text. Starting with fast, affordable remittances powered by AI and crypto rails, we are expanding into credit, savings, and wallet services to support the complete immigrant financial journey. Our ambition is to deliver a white-glove financial experience with the simplicity of a conversation to a community the traditional financial system has historically overlooked.
We are a hyper-growth Series C company, backed by over $300 million in funding from top-tier global investors, including Andreessen Horowitz, QED, Castle Island, Switch Ventures, HTwenty, Monashees, General Catalyst Customer Value Fund. This isn't just about the numbers; it's a testament to the trust our investors have in our vision and our team. Additionally, Félix was selected as an “Endeavour Entrepreneur” and was a recipient of the CrossTech Fintech Startups Award.
Joining Félix means you will be part of a team building a legacy, a company that will outlive us all. This is a rare opportunity to apply your skills to a deeply meaningful mission—serving a community that has been underserved for too long because we are obsessed with our customers. We get things done with urgency and focus, driven by extreme ownership over our impact. We collaborate without ego, fostering radical transparency and fierce loyalty so we can grow together. Because we aim for insanely great rather than just good enough, we stay insatiably curious—always experimenting, building the future today, and delivering a product that truly makes our users' lives better.
About the Role
You define how Félix designs with generative and declarative UI, and you do it while shipping the first version of the platform. Not in the abstract. On WhatsApp, with real products and real money, then across native iOS and Android as the platform expands to multiple surfaces.
Credit, Core Send, Payments, Geos, and Activations each have a PM and a designer. You lead the work that cuts across them: what a user wants when they open Félix, how products show up in the thread and when they shouldn't, how a first send becomes a second and then credit, what the assistant does versus asks. Squad designers own their products. You shape the conversation they build in.
The medium is the job. We’re aiming for a declarative UI on WhatsApp, structured components that render in. A growing share is generative, where the model chooses what to show and say in real time across surfaces. We don't have the rules for either yet. You'll write them, test them, and ship them.
It's hands-on at the staff level. You research, prototype, present, and generate the volume of concepts it takes to find the right answer, working with PMs across squads and the engineers building the runtime. Async-first, lightweight process, fast decisions. The Head of Product Design stays close to the work.
