At Félix, we're 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 powered by WhatsApp, allowing our 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, including QED, Castle Island, Switch Ventures, HTwenty, Monashees, and General Catalyst Customer Value Fund. Félix was selected as an “Endeavour Entrepreneur” and was a recipient of the CrossTech Fintech Startups Award. We are a group of extremely talented and dedicated high-performers, united by our shared obsession with a single goal: empowering our customers. We are all owners of Félix, driven by a bias for action and a true experimentation spirit to get shit done with urgency and focus.
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. We are a team that is fiercely loyal to each other, where radical transparency and constructive feedback are how we grow and push for excellence. We are bold, we care less about what others are doing, and more about creating sustainable value and a product that truly makes our users' lives better. We are building the future, today.
About the RoleWe are seeking a highly skilled Mid-level UX/UI Engineer to design and implement a modular application framework that enables multiple teams to collaborate seamlessly, without conflicts or crashes between components. This role sits at the intersection of design, engineering, and systems architecture, requiring a strong sense of user experience coupled with the technical ability to deliver scalable, robust, and modular solutions.
The ideal candidate is not only a creative designer but also an engineer capable of translating complex requirements into intuitive interfaces and resilient application structures.
Responsibilities- Design and implement a modular UX/UI framework that allows multiple teams to contribute features without breaking interoperability.
- Establish design system guidelines (components, patterns, accessibility standards) to ensure consistency and scalability across teams.
- Collaborate with cross-functional teams (product, engineering, QA) to gather requirements and translate them into design and engineering deliverables.
- Build prototypes, mockups, and production-ready components that balance usability, performance, and maintainability.
- Ensure collaboration-friendly architecture, minimizing merge conflicts, dependency issues, and UI regressions.
- Conduct usability testing and user research to validate design decisions and continuously improve user experience.
- Champion best practices in accessibility, responsive design, and internationalization.
- Mentor junior designers and engineers, promoting a culture of craftsmanship and design thinking.
- 5+ years of experience as a UX/UI Engineer, Frontend Engineer, or similar role.
- Strong proficiency in modern frontend frameworks (React, Angular, Vue) and component-driven development.
- Expertise in design systems (e.g., Material UI, custom component libraries) and modular architectures.
- Solid understanding of collaboration workflows in large engineering organizations (Git, CI/CD, versioning strategies).
- Strong background in user experience principles, visual design, and interaction design.
- Experience preventing and resolving integration issues across multiple teams and modules.
- Familiarity with testing frameworks (Jest, Cypress, Playwright) to ensure UI stability.
- Excellent problem-solving skills, with a balance of creativity and engineering rigor.
- Strong communication and collaboration skills to align design and technical decisions across diverse stakeholders.
- These are the applicable requisites, although equivalent competencies in any of the above will also be considered.
- Experience with micro-frontend architectures.
- Knowledge of design tokens, theming, and multi-brand support.
- Background in fintech or other high-availability systems.
- Contributions to open-source design systems or UI frameworks.
- Competitive salary
- Initial stock options grant
- Annual performance bonus
- Health, dental, and vision plans
- Remote work environment, although we have offices in Miami and México City and would love to work in hybrid model if you are up to it.
- Continuous learning opportunities.
- Unlimited PTO
- Paid parental leave
- Empowering opportunities for growth in a dynamic entrepreneurial environment.
