Python AI Engineer – pharmaceutical industry

As part of a project within our client, the engineering platform has recently been expanded with a RAG as a Service module — a reusable component supporting applications that leverage Retrieval-Augmented Generation. This solution is highly complex, widely visible across the organization, and strategically important for upcoming technology initiatives.

We are therefore looking for an experienced specialist to join the project and contribute to the further development, stabilization, and maintenance of this solution.

Your tasks

• Design, develop, test, and deploy a scalable and secure RAG service using Python and serverless AWS technologies

• Define and manage all required AWS infrastructure using the AWS Cloud Development Kit

• Implement robust pipelines for processing and embedding unstructured data (e.g., PDF, DOCX, HTML), making it ready for semantic search and retrieval

• Build and maintain a RESTful API for the service

• Maintain CI/CD pipelines (GitLab CI)

• Implement comprehensive monitoring and logging to track service health, performance, and cost. Proactively identify and resolve bottlenecks or issues

• Work closely with our cloud engineering, data science, and AI Platform teams to ensure seamless integration, operational excellence, and alignment with company-wide standards

• Focus on delivering value to business users

Requirements

• Over 5 years of professional software engineering experience with a focus on Python, including designing and building scalable, production-grade applications

• Minimum 3 years of hands-on experience with AWS (AWS Lambda, Step Functions, IAM, VPC, S3, DynamoDB, API Gateway, CloudFormation)

• Proven expertise building and managing high-volume RESTful APIs, with a strong understanding of best practices for performance and security

• Familiarity with Docker and building CI/CD pipelines

• A strong conceptual and practical understanding of GenAI concepts, particularly embedding models, vector search, and reranking algorithms.

• Practise with agentic or RAG-specific frameworks like LangChain or LlamaIndex

• Strong sense of ownership and a proactive approach to new tasks or any issues

• Excellent oral and written communication skills in both Polish and English

• Residing in Poland required
