Senior Python(MCP) Developer

We are currently looking for a Python Engineer to join our team and contribute to the development of backend services, integrations, and scalable platform components.

Our client is an innovative technology-driven company focused on building modern digital solutions and scalable platforms. The company is actively investing in automation, intelligent systems, and high-performance software products to support business growth and operational efficiency.

The goal is to design a scalable, multitenant system for exposing data to LLM clients (Claude, ChatGPT, DemandSense UI, and future self-hosted models) via an MCP (Model Context Protocol) server.

• Design small AI clients that will communicate with a FastMCP-based server that exposes analytics tools to LLM clients
• Build OAuth 2.0 multitenant authentication with per-tenant credential isolation and rate limiting
• Define the extensible tool/plugin architecture that lets new data sources and reports be added without core changes
• Design LLM-friendly response schemas — structured JSON, context window management, graceful truncation

• Production experience with FastMCP or MCP protocol
• Strong Python async backend skills
• Solid understanding of OAuth 2.0 in a multitenant SaaS context: token lifecycle, JWT scopes, secret management
• Familiarity with LLM context window constraints and structured tool output design
• Redis caching and cache invalidation strategies
