About Us

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 C company, backed by over $200 million in funding from top-tier global investors, including QED, Castle Island, Switch Ventures, HTwenty, Monashees, and Andreessen Horowitz with support from 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 things 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 Role

We’re looking for a Semi-Senior Software Engineer to join our fintech engineering team. In this role, you’ll take ownership of key projects, contribute to the design and development of scalable systems, and help shape the architecture of our core financial infrastructure. You’ll work closely with product and engineering teams to build services that power payment processing, risk controls, and transaction flows—all while deepening your expertise in Python and Google Cloud Platform (GCP).

This is a great opportunity for an engineer who’s moved beyond the junior stage and is ready to take on more technical responsibility while continuing to learn and grow.

Responsibilities

Design, build, and maintain backend services using Python
Contribute to architecture decisions and help scale payment and financial systems
Write clean, testable, and maintainable code with a focus on performance and reliability
Troubleshoot and resolve production issues with a mindset for long-term improvement
Collaborate with product managers, designers, and other engineers to define and deliver solutions
Use GCP services (e.g., Pub/Sub, Cloud Functions, Firestore, BigQuery) to build cloud-native solutions
Participate in improving CI/CD pipelines, observability, and dev tooling

Requirements

2–5 years of professional software engineering experience
Strong proficiency in Python and backend development fundamentals
Experience working with RESTful APIs, databases (SQL/NoSQL), and cloud platforms (GCP preferred)
Understanding of distributed systems, scalability, and fault tolerance
Strong communication skills and a collaborative, problem-solving mindset
These are the applicable requisites, although equivalent competencies in any of the above will also be considered

Technology Stack:

We are technology agnostic and value candidates with diverse backgrounds. While familiarity with the following is helpful, your willingness to learn and adapt is paramount:

Front-end: React, HTTP, HTML/DOM, JavaScript, CSS, AJAX
Back-end: Python, Flask/FastAPI, REST APIs, Redis, SQL, gRPC
Cloud: Google Cloud services (Firestore, Cloud Storage, Pub/Sub, Google Artifact Registry, Cloud Run, BigQuery, Cloud Composer, etc.)
Infrastructure: Kubernetes, Terraform, NewRelic, PagerDuty

What We Offer

Competitive salary
Initial stock options grant
Annual performance bonus
Health, dental, and vision plans
Work model: currently fully remote, with a future transition to a hybrid setup.
Continuous learning opportunities
Unlimited PTO
Paid parental leave
Empowering opportunities for growth in a dynamic entrepreneurial environment
