Senior FullStack Engineer

thaia®︎

Senior Full Stack Engineer for AI-powered marketing analytics platform handling dashboards and analytics widgets. Collaborating with a team in a high-energy environment based in Buenos Aires.

Posted 4/28/2026full-timeBuenos Aires • 🇦🇷 ArgentinaSeniorWebsite

About the role

Key responsibilities & impact
  • Own the full web app like it’s your reputation on the line (because it is)
  • Ship pixel-perfect dashboards and analytics widgets weekly that make PMs cry happy tears
  • Turn terabytes of ad-spend data into graphs that load in $1B GMV (we’ll know if you’re lying)

Requirements

What you’ll need
  • Former FAANG/unicorn mafia (we already have a couple, you’ll fit right in)
  • Experience with Cube.js or semantic layers that didn’t make you want to quit tech
  • Spanish fluency (helps when the founder starts yelling in Porteño at 2 a.m.)
  • You review your own PRs before hitting “request review” like a goddamn adult
  • “It works on my machine” is a phrase that makes you violently angry
  • You ship robust code or you don’t ship at all — edge cases are your kink
  • You can explain complex systems to a five-year-old (or to our growth guy)
  • You’re fine with zero work-life balance for 6 months if it means we hit $1M ARR and all fly to Mallorca.

Benefits

Comp & perks
  • Real equity that could 50-100x if we don’t fuck it up
  • Two weeks in Mallorca with the entire team the day we hit $1M ARR (already booked)
  • Work directly with a 25-year-old founder who’s done this before and moves at light speed
  • Unlimited mate, asado, and fernetcoke (groceries on us, just don’t fight over who ate whose milanesa)
  • Be part of the wildest 6-month sprint in LATAM history — you’ll tell your grandkids about this
  • Housekeeping covered, pool, gym, padel court, and zero commute
  • Love, chaos, and the best war stories of your career
