• Build and maintain data pipelines, including preprocessing data and post-processing AI model outputs for consumption by applications. 
• Implement best practices for handling sensitive data and maintaining model performance. 

Infrastructure & Deployment: 

• Use Kubernetes and Docker for containerization and orchestration to ensure scalable deployment and management of AI applications. 
• Implement continuous integration and continuous deployment (CI/CD) pipelines for automated testing and deployment of code changes. 
• Maintain a scalable and secure cloud infrastructure, leveraging platforms such as Google Cloud Platform, or Azure for model training, storage, and deployment. 

LLM and GenAI Ecosystem Expertise: 

• Utilize vector databases (e.g., Pinecone, Weaviate, or Faiss) to manage and retrieve embeddings for efficient similarity search and recommendation systems. 
• Work with frameworks for model development and deployment, including Hugging Face Transformers, LangChain, and OpenAI. 
• Optimize and fine-tune LLMs to improve performance based on application needs. 

• Min Bachelor's degree in Computer Science, Engineering, or a related field. 
• 7+ years of experience as a full-stack developer, ideally with a focus on AI model integration. 
• Proficiency in Python
• Strong knowledge of GenAI models and LLMs, including experience with model selection, tuning, and embedding strategies. 
• Experience with API development and integration to facilitate communication between front-end applications and AI models. 
• Working knowledge of containerization technologies like Docker and container orchestration with Kubernetes. Familiarity with cloud platforms (AWS, GCP, or Azure) for AI model deployment and scalability. 
• Proficient in vector databases and their integration with LLM models for enhanced application functionality. 
• Familiarity with database management (SQL, NoSQL) and caching solutions (e.g., Redis). 
• Experience in CI/CD pipelines, code versioning (Git), and DevOps practices. 
• Excellent knowledge of English AND Polish. 

Preferred Qualifications: 

• Knowledge of streaming architectures for real-time data processing and ingestion (e.g., Apache Kafka). 
• Familiarity with serverless architectures (e.g., AWS Lambda) for scalable deployment of AI features. 
• Prior experience in ML frameworks like TensorFlow, PyTorch, or ONNX. 
• Understanding of data privacy and security best practices in AI applications. 

Soft Skills: 

• Strong problem-solving skills and ability to work independently and as part of a team. 
• Excellent communication skills to translate technical requirements into actionable development tasks. 
• Proactive approach to staying updated with emerging AI technologies and frameworks.
