Ampcus Inc. is a certified global provider of a broad range of Technology and Business consulting services. We are in search of a highly motivated candidate to join our talented Team.

Role Details

Location: Remote

Type: Fulltime

Key Responsibilities

• Develop responsive frontend applications using ReactJS (Hooks, state management) to support backend-driven features.
• Integrate AI and LLM-powered capabilities into backend services, including agentic workflows and tool-calling patterns.
• Apply MCP (Model Context Protocol) concepts to connect AI agents with backend services, APIs, and data sources.
• Collaborate with cross-functional teams on API contracts, data flows, and end-to-end feature delivery.
• Design and develop scalable, production-grade backend services using Python frameworks (FastAPI / Flask / Django).
• Architect, build, and integrate RESTful APIs and backend microservices with strong attention to performance, reliability, and security.
• Design and optimize relational database structures using PostgreSQL / MySQL / SQL Server - including schema design, indexing strategies, query optimization, and data modeling.
• Implement robust authentication and authorization frameworks beyond basic JWT - including OAuth 2.0 / OpenID Connect, SSO integrations, session management, token lifecycle (refresh/rotation/revocation), and role-based / attribute-based access control (RBAC/ABAC).

Must-Have Skills

• AI / Agentic AI / MCP: Solid understanding of LLM fundamentals, agentic AI architectures (planning, tool use, multi-step workflows), and the Model Context Protocol (MCP) for agent-system integration; familiarity with frameworks such as LangChain / LangGraph is a strong plus.
• Python Backend (Primary): Strong, hands-on experience building backend services with FastAPI / Flask / Django - async patterns, dependency injection, middleware, API versioning, testing, and production deployment.
• Databases: Deep practical experience with PostgreSQL / MySQL / SQL Server - complex queries, joins, indexing, transactions, ORM usage (SQLAlchemy / Django ORM), and performance tuning.
• Authentication & Security: Demonstrated depth in auth frameworks beyond JWT basics - OAuth 2.0, OIDC, SSO, RBAC, secure session handling, and API security best practices.
• RESTful APIs: Proven experience designing, building, and integrating REST APIs and backend services at scale.
• ReactJS (Secondary): Hands-on expertise with ReactJS - Hooks, component lifecycle, and state management (Redux / Context API).
