Software Engineer (Python)

# Software Engineer (Python) ## About the Role CERN’s Scientific Information Service, within the **OSI Department**, is seeking a **Software Engineer (Python)** to contribute to scientific information platforms including **INSPIRE, SCOAP³, CERN Analysis Preservation, and HEPData**, which are used by researchers and scientific communities worldwide. You will design, develop, and operate backend applications, APIs, integrations, and data-processing workflows, working primarily with **Python and Django**. The role also provides an opportunity to bring **machine learning and emerging AI technologies** into production systems, including information extraction, classification, matching, recommendation, semantic search, Retrieval-Augmented Generation (RAG), Large Language Models (LLMs), and Model Context Protocol (MCP). The focus is on practical production applications rather than fundamental machine-learning research. ## Key Responsibilities - Develop, maintain, and operate scientific information applications using **Python and Django**. - Build and maintain backend applications, APIs, data models, integrations, and data-processing workflows. - Integrate machine learning and AI capabilities into production systems. - Apply technologies including: - Large Language Models (LLMs). - Retrieval-Augmented Generation (RAG). - Semantic search. - Model Context Protocol (MCP). - Evaluate emerging AI technologies and apply them to concrete scientific information use cases. - Explore new ways of connecting scientific information platforms. - Ensure software quality through automated testing, code reviews, monitoring, and continuous integration. - Collaborate with software engineers, product owners, and information specialists on technical solutions and architecture. - Contribute to platforms used by researchers and scientific communities worldwide. ## Required Qualifications The source job description does not explicitly provide a formal list of mandatory qualifications or years of experience. Therefore, no additional degree, certification, years-of-experience, or technical requirements are added here. The role explicitly requires capability in the areas central to the responsibilities, including **Python, Django, backend application development, APIs, integrations, data processing workflows, automated testing, code review, monitoring, and continuous integration**. ## Preferred Qualifications The source job description does not explicitly identify separate preferred qualifications. Experience or interest in the following areas is directly relevant to the role: - Machine learning and AI integration. - Large Language Models (LLMs). - Retrieval-Augmented Generation (RAG). - Semantic search. - Information extraction. - Classification and matching. - Recommendation systems. - Model Context Protocol (MCP). - Production-oriented AI applications. ## Skills & Competencies - **Python** development. - **Django**. - Backend software engineering. - API development. - Data modeling. - Data integration. - Data processing workflows. - Machine learning integration. - Generative AI and LLM applications. - Retrieval-Augmented Generation (RAG). - Semantic search. - Information extraction and classification. - Matching and recommendation systems. - Model Context Protocol (MCP). - Automated software testing. - Code review. - Monitoring. - Continuous integration. - Software architecture. - Collaboration with software engineers, product owners, and information specialists. - Applying emerging technologies to practical production use cases. ## Education & Experience **Education** - No specific educational qualification is stated in the source job description. **Experience** - No specific minimum years of experience are stated. - Relevant experience developing backend applications with **Python and Django** is directly aligned with the role. - Experience integrating AI or machine-learning capabilities into production systems is relevant to the role. ## Work Arrangement & Schedule - **Work arrangement:** Onsite. - **Location:** Geneva, Switzerland. - **Employment type:** Not specified in the source job description. - **Weekly hours:** Not specified. - **Weekend requirements:** Not specified. ## Compensation & Benefits - **Compensation:** EUR 120–180, as provided in the source listing. The source does not specify whether this figure is hourly, daily, monthly, or annual, so it has not been converted or reinterpreted. - No additional benefits are specified in the provided job description. ## Compliance / Additional Information The role is within **CERN’s Scientific Information Service, OSI Department**, supporting scientific information platforms used by researchers and scientific communities worldwide. The position emphasizes production software engineering and practical AI applications rather than fundamental machine-learning research.
