• Develop PoCs and iterate quickly based on results

Requirements

• At least 5+ years of practical experience in Python development and delivering production systems
• Proficiency in advanced Python, especially in scalable, clean code architecture and microservices (e.g., FastAPI, asyncio)
• Understanding of API integration patterns and inter-service communication (e.g., REST, Kafka)
• Track record of at least two backend/data-intensive solutions successfully delivered to production, ideally involving high-throughput APIs, data pipelines, or search/retrieval systems

• English proficiency at B2 level or higher

Nice to have

• Familiarity with agentic frameworks such as LangChain/LangGraph, LlamaIndex, or similar
• Practical experience integrating LLMs (e.g., OpenAI, Anthropic) into production applications, including prompt engineering and tool/function calling
• Knowledge of RAG architectures, embeddings (e.g., OpenAI), and vector databases (e.g., FAISS, Azure AI Search)
• Understanding of LLM evaluation, guardrails, and cost/latency trade-offs when designing AI-powered services
