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 Ability to communicate complex technical

topics clearly to both technical and non-technical stakeholders and to

work effectively across backend, frontend, AI, cloud, data, and

integration domains Im Rahmen der Arbeitnehmerüberlassung suchen wir
