Long Term Contract

Overview

We are seeking a hands-on Full Stack Engineer to design, build, and deliver production-grade platform services for an AI-native enterprise system.

This role sits at the intersection of frontend engineering, backend services, and agentic AI platforms, supporting AI agents and orchestration workflows (LangGraph). You will work across the full stack—owning APIs, data layers, and user interfaces—while ensuring scalable, secure, and observable systems in a cloud-native environment.

This is a 100% hands-on role, focused on building and operating production systems end-to-end.

Key Responsibilities

Full Stack Development

• Design and build modern frontend applications using React or Angular (TypeScript, component-driven architecture, state management)
• Develop backend services and APIs using Python (FastAPI preferred) or similar frameworks
• Implement secure, scalable REST APIs and real-time communication (WebSockets / streaming)
• Ensure clean separation of concerns across frontend, API, and data layers

Agentic AI Platform Integration

• Build backend services that act as tools and APIs for AI agent workflows
• Design APIs that provide structured, deterministic data to LLM-based orchestration layers
• Support Human-in-the-Loop (HITL) workflows, including approval flows, callbacks, and state management
• Integrate with tool-calling frameworks and external AI orchestration systems
• Enable observability of agent workflows through structured logging, tracing, and correlation IDs

Backend & API Engineering

• Develop layered backend architectures using FastAPI, dependency injection, and clear interface boundaries
• Implement asynchronous data access patterns and high-performance APIs
• Define and enforce API contracts, validation models (e.g., Pydantic), and error handli...
