AI Application Engineer

Romania

About the role:

The AI Application Engineer bridges the gap between advanced AI capabilities and practical software implementation. This role focuses on embedding pre-trained large language models, intelligent agents, and RAG systems into production-grade applications, enabling natural language reasoning, automation, and data-driven interactions across business platforms. This role is more focused towards applied engineering of intelligent systems rather than core machine learning development.

Responsibilities:

Design and implement AI-driven features powered by LLMs, vector search, and retrieval-augmented generation techniques

Build, integrate, and orchestrate intelligent agents capable of reasoning and autonomous task completion using frameworks such Azure AI Foundry, Google Vertex AI, Amazon Bedrock or LangChain

Connect AI models and agents with APIs, external tools, knowledge bases, and databases to support dynamic workflows

Develop backend services and microservices that interact efficiently with model endpoints (e.g., OpenAI, Anthropic, Azure OpenAI, Gemini or other cloud or local models)

Prototype and productionize AI copilots, assistants, and chat interfaces within enterprise or SaaS environments.

Implement retrieval mechanisms using vector databases (e.g., Azure AI Search, Pinecone, FAISS, Milvus) to enable contextual grounding of language model outputs

Collaborate with product and UX teams to align AI integrations with user needs and ensure reliable, explainable system behavior

Monitor AI-driven services for latency, cost efficiency, and performance consistency in real-world deployment

Maintain documentation for AI integration frameworks, agent logic, and deployment architectures

Lead the development and deployment of AI applications, managing the full lifecycle from ideation to production

Mentor junior engineers, providing guidance and support to enhance team performance and technical prowess

What we are looking for:

Bachelor's or Master's degree in Computer Science, Software Engineering, AI, or a related technical field

Strong programming experience with at least one of the following languages: Python, TypeScript or , Java

Familiarity with modern LLM frameworks and toolkits: Semantic Kernel Agent Framework, Azure AI Foundry Agent Service, LangChain, LlamaIndex, etc

Practical understanding of vector search, RAG design, and prompt engineering

Experience with cloud AI platforms (Azure AI Services, AWS Bedrock, or GCP Vertex AI)

Proven experience integrating APIs and deploying AI-based microservices

Robust knowledge of REST, GraphQL, and event-driven architecture

Ability to reason about agent workflows, state management, and orchestration logic

Nice to have:

Experience with building conversational frontends (e.g., web chat UIs, Microsoft 365 Copilot plugins, Slack/Teams bots)

Understanding of model evaluation, safety mechanisms, and hallucination prevention

Hands-on experience with cloud platforms, such as Azure, GCP, AWS

Hands-on experience with popular LLMs, such as GPT, Gemini, Claude, including the ability to fine-tune and optimize these models for specific use cases

Familiarity with containerization (Docker, Kubernetes) and CI/CD practices

Experience using monitoring tools for agent observability (e.g. Azure AI Foundry Observability, Langfuse, Prometheus, OpenTelemetry)

Eagerness and ability to learn new skills and solve problems

Contributions to open-source agentic or LLM integration frameworks or a portfolio of projects (e.g., GitHub repository) demonstrating practical experience in building applications with LLMs, agents, or RAG systems is highly desirable
