ABOUT THE ROLE:

We are building AI-powered platforms for transformative applications in education. This work involves creating scalable, AI-driven systems with personalized interactions, adaptive features, content delivery, and analytics to deliver meaningful user experiences at scale.

We're looking for generalist fullstack engineers who thrive on owning significant parts of the system end-to-end: from intuitive user interfaces to robust backend services, data infrastructure, and deep AI integrations.

• Develop backend services, APIs, and data models to support high-volume, multi-user environments.
• Integrate AI capabilities (tutoring, content generation, personalization) deeply into the platform.
• Design and implement database schemas and queries for tracking progress, engagement, and reporting.
• Collaborate on integrations with external systems and data sources to enable comprehensive workflows.
• Ensure the platform is performant, secure, reliable, and scalable for broad deployment.
• Work closely with product, design, AI, and domain experts to iterate rapidly based on user feedback and outcome data.

BASIC QUALIFICATIONS:

• Experienced fullstack engineer comfortable owning features across the entire stack (frontend, backend, database).
• Strong generalist who can fluidly move between UI/UX implementation, API design, data modeling, and systems architecture.
• Proficient in modern web technologies (e.g., TypeScript/React/Next.js on the frontend; Python/FastAPI or similar on the backend).
• Solid experience with relational databases and designing schemas for complex domains.
• Good eye for UX design and strong attention to detail.
• Familiarity with large-scale user-facing applications or domain-specific platforms is a strong plus.
• Passionate about building products that create real-world impact.
• Excited to work in a fast-moving, high-impact environment with significant ownership.
• Willingness and ability to travel frequently to the customer site in El Salvador and/or work onsite as required by project needs
• Full professional fluency in English and Spanish (bilingual), with excellent verbal and written communication skills in both languages

PREFERRED SKILLS AND EXPERIENCE:

• Primarily JavaScript/TypeScript and Python
• Frontend: React, Next.js
• Backend: FastAPI or Django
• Database: SQL, Redis
• Infrastructure: AWS/GCP, Docker, Kubernetes
