Job Description

We are looking for a Full Stack Developer based in Latin America to work on a long-term project for one of our clients, a Data Analytics and Business Intelligence services company based in Los Angeles.

Responsibilities

• Architect and develop high-concurrency backend services in Python (FastAPI/Django) to support transactional workflows such as shopping carts, order processing, and complex business operations.
• Design and implement agent-ready APIs using Pydantic for strict type enforcement and OpenAPI/MCP for autonomous service discovery, enabling agents to reliably execute business actions.
• Build and maintain secure, scalable integration frameworks using technologies such as OAuth2 and Webhooks to connect the platform with external ERP and procurement systems.
• Develop observation-friendly APIs with advanced error handling and structured response hints that allow autonomous agents to diagnose and correct invalid requests during multi-step workflows.
• Contribute to frontend development using React or Angular to support backend-driven features and internal tools.
• Integrate frontend components with backend APIs, ensuring smooth data flow and proper error handling.
• Collaborate on full-stack features, supporting UI implementation where needed while maintaining a backend-first focus.
• Leverage AI-assisted development workflows, utilizing autonomous coding agents to plan, generate, and test backend services while maintaining high code quality through agent-supported reviews.
• Implement secure authentication and authorization mechanisms using JWT and OpenID Connect to ensure proper permission boundaries for both human users and AI agents.
• Monitor and optimize API latency and database performance (PostgreSQL / MS SQL) to support real-time interactions for web and mobile applications as well as high-frequency automated agent calls.
