Senior Data Scientist (CDMX)

About Común

Comun’s mission is to help Hispanic immigrants turn their hard work into upward mobility — starting with financial services that support their transition from a cash-based system to the digital economy.

We offer checking accounts that can be opened using 100+ types of Latin American IDs, access to over 90K locations nationwide to deposit cash, international transfers to 17 countries at market‑leading rates, and 24 / 7 bilingual customer support with 5 min SLA across email, chat, and phone.

We currently process over $1.5B in annual transaction volume and surpassed $100M in annualized international transfers just six months after launch. Comun has raised +$50M from top investors including Redpoint, Costanoa Ventures, and South Park Commons. Our team brings experience from leading fintech companies like Brex, Nubank, and Mercury.

We believe immigrants are the ultimate entrepreneurs — driven by relentless ambition and a vision for a better future for their families. Comun exists to serve them throughout their journey.
