Data Analyst, AI
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 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.
About the role
About the Role At Félix, we are building the future of remittances through a seamless, AI-powered WhatsApp experience. We’re looking for a
Data Analyst for our AI Team,
who is obsessed with making our chatbot & customer experience "insanely great."
You won’t just be pulling data; you will be the guardian of our AI’s quality. You will work closely with Engineers and Product Managers to ensure our agents are accurate, helpful, and human-centric. We need a "natural investigator" who can dive into a dataset to understand why a model hallucinated or where the context was lost, turning those findings into a better product for millions of Latino immigrants.
Responsibilities
- AI Performance & Metrics: Design and maintain dashboards in PowerBI tools (Omni, a Looker-equivalent) to track the "health" of our AI agents, focusing on F1 scores, precision-recall tradeoffs, and intent recognition accuracy.
- Quality Control (The "Anti-Hallucination" Task): Deep dive into conversation logs to identify, categorize, and quantify hallucinations or instances where the AI lost context.
- Data Modeling for AI: Build and optimize SQL-based data models on our GCP (BigQuery, DBT, Firestore) infrastructure to evaluate model versions and prompt iterations.
- Collaborative Experimentation: Partner with the AI Engineering team to analyze A/B tests on different LLM prompts and configurations, balancing the tradeoff between response speed and accuracy.
- User-Obsessed Insights: Translate complex AI metrics into "human stories" for the rest of the team, explaining how technical tweaks improve the actual user experience on WhatsApp.
Requirements
- Experience: 2-3+ years of experience as a Data Analyst, ideally within AI, NLP, or Product-focused teams.
- Proven 1-2+ years of experience measuring Chatbot/LLM metrics. You should be comfortable discussing F1 scores, confusion matrices, and the tradeoffs between model creativity and factual accuracy.
- Technical Core: Strong SQL skills (you’ll live in BigQuery / DBT / Firestore) and experience with BI tools like Omni / Tableau / PowerBI / Looker or similar.
- The "Felix" Vibe: A startup mindset—you are proactive, you have a bias towards action, and you don’t wait for permission to fix something that’s broken.
- Communication: Ability to explain to a non-technical stakeholder why a 1% drop in F1 score matters for our users and impact on other KPI’s.
- Language: Advanced English and Spanish (crucial for analyzing our users' regional nuances).
Nice to have
- Python Mastery: Experience using Python for data manipulation (Pandas/NumPy) or basic NLP libraries.
- GCP Ecosystem: Familiarity with BigQuery, Vertex AI, or Cloud Storage.
- Start-up DNA: Previous experience in high-growth fintechs or AI-first companies.
- Curiosity: A genuine interest in how LLMs work and stay up-to-date with the latest in conversational AI.
- Partially or fully fluent in Portuguese
