Backend AI Engineer

España Remoto Full-time 3+ years of experience in backend development with Java (Spring Boot) or .NET (C#), combined with hands-on experience designing and integrating AI-powered solutions using LLMs. Knowledge of RAG, AI agents, orchestration, prompt engineering, function calling / tool use, and AI frameworks such as Azure OpenAI, Azure AI Foundry, Semantic Kernel, LangChain, or LangGraph. Experience with cloud environments, primarily Azure and/or AWS.

At MindShore, we’re looking for a Backend AI Engineer to join an exciting project with one of our clients, a Spanish technology consulting company specializing in digital solutions, software development, and innovation, delivering technology-driven projects across different industries!

We’re looking for a technically strong, curious, and proactive professional with solid backend development experience and a strong background in Artificial Intelligence. The ideal candidate combines software engineering foundations with hands-on experience designing, developing, and integrating AI-powered solutions using Large Language Models (LLMs).

We are particularly interested in professionals who go beyond using AI as a development assistant and have experience building AI-driven solutions and contributing to their architecture. We value people who enjoy exploring new technologies, taking ownership, proposing solutions, and turning ideas into functional applications.

Key Requirements

• Solid experience in backend development using Java (Spring Boot) or .NET (C#).
• Strong understanding of API design and integration, as well as microservices architectures.
• Demonstrable experience designing, developing, and integrating AI-powered solutions using Large Language Models (LLMs) in real-world projects, ideally deployed in production environments.
• Hands-on experience or strong practical knowledge of RAG architectures, AI agents, orchestration, prompt engineering, and function calling / tool use.
• Knowledge of AI frameworks and platforms such as Azure OpenAI, Azure AI Foundry, Semantic Kernel, LangChain, LangGraph, or similar.
• Experience working with cloud environments, preferably Azure and/or AWS.
• Strong technical curiosity, problem-solving skills, and a proactive mindset.
• Ability to propose technical solutions, contribute to architectural decisions, and take ownership of initiatives.

Nice to Have

• Experience implementing and maintaining LLM-based solutions in production environments.
• Personal AI projects, GitHub repositories, open-source contributions, or technical proofs of concept demonstrating hands-on AI development experience.
• Experience working with vector databases, embeddings, and advanced RAG architectures.
• Familiarity with AI agent frameworks and multi-agent systems.
• Experience with both Java and .NET ecosystems.
• Good level of English.

Responsibilities

• Design, develop, and maintain backend solutions using Java (Spring Boot) or .NET (C#).
• Design and integrate APIs and microservices architectures.
• Design, develop, and integrate AI-powered solutions using Large Language Models (LLMs).
• Build and implement RAG pipelines, AI agents, and orchestration workflows.
• Work with prompt engineering, function calling, and tool integration.
• Evaluate and integrate AI frameworks and platforms into backend architectures.
• Contribute to the architecture and design of scalable, maintainable, and reliable AI-powered solutions.
• Research emerging technologies and identify opportunities to incorporate AI into software applications.
• Take initiative, propose improvements, and turn technical ideas into functional solutions.
• Collaborate with technical teams to solve challenges and continuously improve existing solutions.

Working Conditions

• Work Model: 100% remote.
• Location: Spain.
• Employment Type: Full-time, Spanish payroll.
• Team: Collaborative technical environment focused on backend development, AI engineering, and innovative technology solutions.
• Opportunity: Work on technology projects involving Artificial Intelligence, backend engineering, and the design of real-world AI solutions, with opportunities to experiment, contribute ideas, and grow technically.

Required Skills
