Role Overview
We are seeking a hands-on Senior Backend Engineer to design, build, deploy, and operate the API and MCP server that provide access to our factor library.
You will own the service architecture, library integration, authentication, licensing controls, documentation, and production reliability. Working closely with the factor-library team, you will translate supported capabilities into secure, consistent, and easy-to-use interfaces.
This role focuses on API and MCP engineering, with Python as the primary backend language.
Key Responsibilities
API and MCP Development
• Build and maintain production APIs using Python and FastAPI or a comparable framework.
• Develop an MCP server that enables compatible AI clients to discover and invoke supported factor-library capabilities.
• Define request and response schemas, input validation, error handling, and interface versioning.
• Build a shared integration layer to ensure consistent behaviour across the API and MCP server.
• Manage library execution, including blocking computations, concurrency, timeouts, and resource limits.
• Maintain compatibility as the factor library and client interfaces evolve.
Security and Access Management
• Implement authentication, secure credential handling, and organisation-level authorisation.
• Enforce client licensing and feature entitlements across API endpoints and MCP tools.
• Ensure each library invocation operates within the authenticated client’s permissions.
• Implement appropriate request limits, audit logging, and protection of sensitive information.
Production Engineering
• Build automated tests covering library integration, interface behaviour, permissions, and failure scenarios.
• Containerise services and establish repeatable deployment, release, and rollback processes.
• Implement health checks, structured logging, metrics, monitoring, and alerts.
• Diagnose production incidents and improve service reliability, performance, and operating efficiency.
• Maintain op
