Full-stack Developer

About the role

Contably is Bolivia's first cloud-native accounting and electronic invoicing platform, built for the country's SFE compliance mandate. We're expanding our engineering team with a Mexico-based Full-stack Developer to help us build and scale the platform across Latin America.

You'll work directly with our founding team on a modern stack, ship real features to real customers, and have meaningful ownership of what you build. This is a contractor engagement — remote-friendly within Latin American time zones.

Stack

What you'll do

• Build and maintain frontend features with React 18 + TypeScript + Vite
• Write backend logic via Supabase Edge Functions (Deno runtime)
• Design and optimize PostgreSQL schemas for accounting and invoicing data
• Integrate with government invoicing APIs (Bolivia SFE/SIAT and future Latin American markets)
• Collaborate asynchronously with the founding team across time zones
• Ship fast, iterate based on real customer feedback

Requirements

• 2+ years of full-stack experience
• Strong React + TypeScript skills
• Comfortable with relational databases (PostgreSQL preferred)
• Spanish required — English intermediate or above a plus
• Supabase or Deno experience desirable, not required
• Based in Mexico; LATAM time zone overlap required
• Experience with fintech, government APIs, or compliance systems is a plus

Compensation

Competitive USD rate based on experience and scope. Engagement starts as project-based or hourly with the expectation of ongoing involvement as the platform scales into new markets.
