LeverX is looking for a Middle GenAI Engineer. As an Engineer specializing in Generative AI, you will be at the forefront of integrating advanced AI technologies into scalable back-end systems. In this role, you will play a key part in shaping innovative generative AI and chatbot applications that drive business value.

RESPONSIBILITIES

• Design and deploy microservices and back-end systems with a focus on generative AI and chatbot applications.
• Integrate and optimize third-party AI products, including LLMs and related orchestration frameworks.
• Optimize AI pipelines using vector databases (e.g., Pinecone, Chroma, Vanna) and tools like LangChain and LlamaIndex for efficient retrieval-augmented generation.
• Collaborate with cross-functional teams to capture, clarify, and translate stakeholder requirements into technical solutions.
• Stay ahead of AI trends by prototyping emerging tools and standards (OpenAI APIs, AI agents, multimodality) to drive innovation.
• Ensure adherence to AI protocols, standards, and best practices throughout the software development lifecycle.

Requirements

• At least 2+ years of experience in Back-End roles, including building microservices (FastAPI, Django) and working with REST/gRPC APIs.
• Hands-on experience working with GenAI tools and frameworks, including LangChain, LlamaIndex, and RAG pipelines.
• A solid grasp of AI integration patterns — prompt engineering, model fine-tuning, and vector database optimization.
• Upper-Intermediate English with strong client-facing skills.

Opportunities

• Excellent work environment: the company is big enough to be reliable, yet small enough to be person-oriented;
• Full-cycle projects and product development;
• Training & development-focused approach: clear roadmap for training employees to sustain and enhance the productivity of the organization as a whole, internal technical meetups, free English classes;
• Collaboration with the teams from the European Union and the United States both onsite and remotely.
