About The Position

At Félix, 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.

Requirements

8+ years designing consumer products with a high bar for craft, including two years leading design on a conversational or AI-native product.
A track record of leading discovery across product teams and turning it into direction they adopted. You can point to research that changed what got built.
Hands-on experience with declarative UI: components as structured specs that engineers instantiate, not screens they copy. Bonus if you’ve worked with generative UI (json-render.dev, A2UI): the constraints, defaults, and recovery paths for interfaces a model assembles at runtime.
Range from pixel to strategy. You solve the component, reframe the pattern, and defend the tradeoff to non-designers.
Deep Figma fluency and comfort prototyping in code. At least two mobile products shipped end to end.
Fluency with AI as a creative partner (Cursor, Claude Code, Claude Design, Codex) used to amplify craft, not shortcut it.
A high tolerance for constraint: legal, risk, model behavior, and failure states you don't get to design away.
You share work before it's polished and invite critique early.
A portfolio link (with password, if needed) is required. It should include at least one conversational or generative UI project with your reasoning visible.
Communication skills: Native or near-native Spanish and advanced English. Our users speak Spanish; so do we.
Bonus: experience in fintech or another regulated domain, or with WhatsApp Business Platform or similar messaging surfaces.
These are the applicable requisites, although equivalent competencies in any of the above will also be considered.

Responsibilities

Lead discovery across products. Own the questions no single squad owns: why users stop after a first send, where the conversation loses them. Talk to users, read transcripts, pull analytics, and make the findings hard to ignore.
Define how we design with generative and declarative UI. What the model can compose, what stays fixed, how it recovers from a wrong guess. Set the patterns while shipping v1, then harden them.
Ship v1 on WhatsApp. Applied use cases first, with the squads. Then define what the patterns become on native iOS and Android.
Set direction for the conversation. How products coexist in one thread, how context carries, and how users always know what Félix is doing with their money.
Land it with squad designers. Bring the direction into Credit, Core Send, Activations, and the others. Critique in the medium. Adjust when their constraints teach you something.
Treat compliance as design material. Disclosures and consent live in the conversation. Design them with legal and risk, as part of the experience.
