What We Offer
Equal Opportunity Employer
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 built on 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. 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. 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.
We are transitioning our core operational capabilities from third-party low-code solutions to a robust, highly scalable, in-house ecosystem. In this role, you will be a foundational member of the CX Platform team.
You will not just be building isolated screens; you will be architecting the core platform that powers our operational tooling. We are looking for an engineer who is ready to tackle platform-level challenges: scalable frontend architecture, modular decoupling, complex state management, and secure data aggregation layers.
If you are obsessed with frontend architecture and building performant tools that make complex business operations remarkably efficient, this is your place.
We are technology agnostic and value strong conceptual foundations over syntax memorization. You will work with:
- Front-end: Advanced React, Component-Driven UI, Modular CSS Architectures.
- Architecture: Distributed modular paradigms, Monorepo management, Modern build tools and bundlers.
- Platform/Data Layer: Aggregation patterns, secure API proxies, Node.js environments.
- Cloud & Infra: CI/CD pipelines for frontend ecosystems, strict environment isolation, RBAC integrations.
- Platform Architecture: Architect, build, and maintain the foundational platform ecosystem that will seamlessly host various operational modules and applications for the CX team.
- Secure Data Aggregation: Design and implement the necessary intermediary layers to securely aggregate data, standardize payloads, and enforce strict authorization rules (RBAC) before sensitive information reaches the client application.
- Developer Experience (DX): Establish technical patterns, templates, and scaffolding to ensure a collaboration-friendly architecture, minimizing merge conflicts, dependency hell, and UI regressions.
- Operational Efficiency: Collaborate closely with core business stakeholders to understand their daily operational workflows and build technical solutions that drastically reduce handling times and cognitive load.
- Mentorship: Elevate the engineering culture by championing best practices in frontend architecture, accessibility, and code quality.
- 5+ years of experience as a Software Engineer in a fast-paced, dynamic environment.
- Fluent or advanced English (Upper-intermediate is fine, as long as you can communicate clearly in a technical setting).
- Advanced React & UI Engineering: Deep understanding of React (internals, rendering lifecycles, advanced hooks) and solid foundations in web standards (HTML/DOM, CSS, HTTP).
- Frontend Architecture: Proven track record of designing scalable frontend solutions (routing ecosystems, state management at scale, bundle optimization) rather than just consuming existing setups.
- Systemic Backend Integration: Strong capability to design and consume secure API integration layers (Node.js/TypeScript) that serve as secure proxies or aggregators for core microservices.
- Tooling & Workflows: Solid understanding of collaboration workflows in large engineering organizations (Git strategies, CI/CD for frontends, build/bundling optimizations).
- Problem Solving: Excellent problem-solving skills with a balance of creative UI implementation and strict engineering rigor.
Nice to have (highly desirable):
- Platform Experience: Previous experience working in Core Frontend teams, Platform Enablement teams, or building Developer Tools.
- Internal Tools / Enterprise Ops: Experience building internal tools, CRM systems, or high-density data applications focused on operational efficiency and scale.
- Advanced Architectures: Real-world experience implementing distributed frontend architectures and working within complex Monorepo setups.
- Regulated Environments: Background in highly regulated sectors (Fintech, Healthcare) dealing with strict role-based access control (RBAC) and data isolation.
- 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 a 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
