  • Develop local services (in Python or Java) to serve offline models when needed.

  • Design and maintain REST/JSON endpoints for communication between Java services and AI modules.

  • Personalize and adapt model outputs through prompt engineering.

  • Implement logic for natural language understanding, question/answer generation, and response analysis.

  • Ensure data privacy, performance, and security in AI integrations.

  • Collaborate with backend, frontend (Angular), and product teams for seamless integration.

  • Experience with LLMs (e.g., GPT, Falcon, LLaMA, BloomZ).

  • Experience integrating APIs (OpenAI, HuggingFace, Ollama).

  • Strong Python and Java skills for backend development (FastAPI, Flask).

  • Expertise in Java backend development, especially with Spring Boot.

  • Familiarity with AWS services (API Gateway, EC2, Lambda, etc.).

  • Experience deploying AI models in on-premises environments.

  • Familiar with model quantization and serving tools (HuggingFace, llama.cpp, Ollama).

Nice to Have:

  • Familiarity with LangChain, vLLM, or Retrieval-Augmented Generation (RAG).

  • Experience with multilingual prompt engineering.

  • Working knowledge of Angular.

  • Experience with AI solutions in offline enterprise environments.

  • Knowledge of privacy regulations (e.g., GDPR) and edge computing best practices.

Who You Are:

  • Solution-oriented, with strong problem-solving skills.

  • Comfortable working autonomously and taking technical ownership.

  • Eager to collaborate with cross-functional teams.

  • Curious and passionate about exploring new AI technologies.

Additional Information

What We Offer:

  • An innovative product focused on real-world Generative AI.

  • Influence in technical decisions and solution architecture.
