Your Responsibilities:
- Take technical ownership of the reliable and stable operation of AI-powered applications in production
- Monitor application health and investigate incidents using logs, metrics, alerts, and distributed traces
- Assess the technical impact and business implications of production issues and coordinate their resolution from initial analysis through closure
- Perform root cause analyses across the entire application stack, including Python backends, React frontends, REST APIs, databases, system integrations, and application configurations
- Read, review, debug, maintain, and continuously improve existing Python codebases
- Develop and deploy bug fixes, hotfixes, and technical improvements through established testing, peer-review, and CI/CD processes
- Troubleshoot end-to-end application flows, including frontend-backend interactions, data-processing pipelines, AI integrations, and external dependencies
- Implement smaller bug fixes and enhancements in React and TypeScript where required
- Distinguish application-level issues from platform or infrastructure failures and collaborate closely with the responsible engineering teams
- Improve application logging, monitoring, alerting, error handling, resilience, performance, and overall observability
- Maintain application dependencies and support configuration, security, and version updates
- Develop automated unit and integration tests for bug fixes and technical improvements
- Implement sustainable corrective measures to prevent recurring production issues
- Maintain technical documentation, operational runbooks, and troubleshooting guidelines
- Support knowledge transfer, go-live activities, hypercare phases, and the transition into regular operations
- Communicate technical status, risks, workarounds, and resolution progress clearly to the AI Service Manager and relevant stakeholders
- Automate recurring operational, monitoring, and diagnostic activities
What You Bring:
- 5+ years of professional experience in Python backend development, including the design, maintenance, debugging, and optimization of production-grade applications
- Strong expertise in Python technologies and frameworks such as FastAPI, Flask, asynchronous programming, object-oriented development, REST APIs, OpenAPI/Swagger, OAuth2, JWT, PostgreSQL, SQLAlchemy, and SQL
- Proven experience working with complex codebases, performing root cause analysis, resolving production incidents, and delivering sustainable solutions in business-critical environments
- Hands-on experience with automated testing, Git-based development workflows, code reviews, and modern software engineering best practices
- Strong background in cloud-native and distributed applications, including Docker, CI/CD pipelines, application monitoring, logging, alerting, observability, and production deployments
- Experience with AWS services such as ECS/Fargate, CloudWatch, S3, load balancing, and queue-based architectures; Infrastructure-as-Code experience (e.g., Terraform) is considered an advantage
- Solid understanding of AI-powered applications, including LLM integrations, Retrieval-Augmented Generation (RAG), embeddings, vector databases, document processing, AI agents, tool calling, and multi-step orchestration workflows
- Experience integrating AI and LLM services through APIs and investigating AI-specific production issues related to model behavior, retrieval quality, latency, context limitations, and external dependencies
- Familiarity with Azure OpenAI, LangChain, LangGraph, LlamaIndex, or similar AI application frameworks is a plus
- Understanding of frontend-backend interactions with the ability to troubleshoot through browser developer tools, API traces, and application logs; basic React and TypeScript knowledge is beneficial
- Experience working with enterprise integrations and platforms such as SAP, SAP Gateway, EDI, Snowflake, or comparable enterprise environments is advantageous
- Proven ability to work independently within complex system landscapes and collaborate effectively with backend, frontend, cloud, platform, data, AI, and business teams
- Successfully completed vocational training, a university degree, or equivalent practical experience in a relevant technical field
- Fluent English communication skills, both written and spoken
- Strong sense of ownership, analytical thinking, and problem-solving capabilities, combined with a structured, pragmatic, and service-oriented approach
