Job description

Senior Python Software Architect
Location: London OR Liverpool (Hybrid)

We are supporting a global business in their search for a Senior Python Software Architect to join a growing team working on an innovative internal platform. While this initiative is connected to the GenAI space, the focus is purely software engineering, not AI development. The objective is to build an Agentic Framework designed to help internal teams develop, deploy, govern, and monitor agent-based systems efficiently and securely.

This role requires a deep technical understanding of Python and modern backend architectures, with the opportunity to play a key part in shaping frameworks that will be adopted enterprise-wide.

Extensive Python Expertise (10-15 years):

• Strong experience with Python meta-programming (functions, classes, inheritance, decorators, context variables)
  
  
• Deep understanding of common design patterns (abstraction, factory, adapter, façade, iterator, etc.)
  
  

FASTAPI Specialist:

• In-depth knowledge of FASTAPI internals; ability to extend and customize
  
  
• Experience integrating authentication (Azure AD, OAuth2) and applying API security best practices
  
  

Containerization & Orchestration:

• Proven experience containerizing APIs (Docker) and deploying on orchestration platforms (Kubernetes)
  
  

LangChain / LangGraph (or similar):

• Understanding of agent-based frameworks, callbacks, telemetry (e.g., OpenTelemetry)
  
  

Architectural Leadership:

• Track record of driving best practices in system architecture, microservices design, and reusable infrastructure templates
  
  
• Strong experience designing and scaling backend systems to support agentic and event-driven frameworks
  
  

Asynchronous Programming:

• Proficiency with async/await, concurrency models, and event-driven architectures
  
  

Nice-to-Have Skills:

• Familiarity with additional Agentic Frameworks (OpenAI API, Autogen, Google ADK, etc.)
  
  
• Experience building MCP servers
  
  
• Knowledge of data engineering principles related to telemetry, distributed tracing, and log analytics
