Senior Python Engineer (Serbia)

We are seeking an experienced Senior Python Software Engineer to join our team, driving excellence in building scalable, maintainable, and production-grade backend systems for AI-driven applications. 
This role focuses on designing and establishing robust backend architecture and ensuring our Python-based solutions meet enterprise standards for performance, modularity, and operational readiness. 

What you'll do:

•  Backend Architecture & Development 

Design and implement modular, scalable, and maintainable backend architectures for Python-based applications. 

Define standards for multi-tiered architecture, dependency injection, module management, and configuration strategies across environments. 

Lead efforts to improve API design, data modeling, and code organization aligned with long-term product scalability. 

• Technical Guidance & Mentorship 

Act as technical coach to the engineering team, transferring best practices in backend engineering, system design, and clean code principles. 

Involve in Review of new or existing implementations and introduce structured improvements for scalability, maintainability, testability, and reusability. 

• DevOps, CI/CD, and Quality Enablement 

Design system architecture to support integration of backend services into CI/CD pipelines. 

Collaborate with DevOps and QA teams to ensure solutions are test-driven, monitoring ready, and accessible for automated testing workflows. 

Introduce performance monitoring, logging, and error tracking mechanisms, integrating with modern observability tools. 

Optimize iteration cycles via structured code reviews and continuous feedback loops with the team. 

• Collaboration in AI Solution Delivery 

Work closely with AI engineers, data engineers, and cloud specialists to integrate backend APIs with AI/LLM pipelines, RAG systems, and vector stores. 

Learn and progressively apply Generative AI concepts (prompt management, context handling, observability) to ensure backend readiness for intelligent features. 

Contribute to architectural discussions and technical documentation supporting AI CoE frameworks and client AI projects. 

Who are you:

• 7+ years of experience in software development with Python, including backend systems, APIs, or enterprise applications. 
• Expertise in FastAPI, Flask, or equivalent frameworks for building production-grade REST or GraphQL APIs. 
• Proven experience designing tiered architectures and applying design patterns (e.g., repository, service, dependency injection). 
• Hands-on experience with CI/CD pipelines, unit/integration testing frameworks, and logging/monitoring tools. 
• Strong understanding of modularization, configuration management, and code quality principles. 
• Understanding of modern API security (OAuth2, OIDC, integration with EntraID or similar).

Nice-to-Have: 

• Familiarity with AI or Generative AI solutions, LLM-based architectures, or RAG pipelines. 
• Experience with Azure Cloud Services (Functions, App Service, Container Apps, APIM, etc.). 

We appreciate the interest of all applicants. Please note that only those whose qualifications align closely with the position requirements will be contacted for the next steps in the selection process.

All applications will be handled with confidentiality.
