Luupli Ltd is hiring an AI Engineer

Luupli Ltd is looking for an AI Engineer to play a pivotal role in developing the intelligent systems that power our AI features. You will build and orchestrate agentic workflows, working on RAG pipelines, multi-agent LLM orchestration, and integrations that drive product capabilities like auto-captioning and content moderation. This is a full-stack AI role spanning from backend APIs to product-facing features within a company committed to using social media as a force for good.

What You'll Do

• Build and deploy multi-agent AI workflows using LangGraph, LangChain, or Google’s Agent Development Kit.
• Implement RAG pipelines using embeddings, semantic chunking, and vector databases like FAISS, Pinecone, or Weaviate.
• Integrate both hosted and open-source LLMs (OpenAI, Gemini, Claude, Ollama, Mistral) into intelligent systems.
• Build REST APIs with FastAPI and internal tools with Streamlit to expose AI functionality.
• Deploy production-grade services on Google Cloud Platform using Vertex AI, Cloud Run, Cloud Functions, IAM, and Pub/Sub.
• Embed AI into platform features such as auto-captioning, generative media, feed personalization, and real-time moderation.
• Maintain modular, testable, observable, and secure code across the AI system lifecycle.

What We're Looking For

• 3+ years experience in applied AI/ML engineering with production-level deployments.
• Strong Python development skills with full-stack AI engineering experience: FastAPI, Streamlit, LangGraph/LangChain, PyTorch/Transformers, and FAISS/Weaviate/Pinecone.
• Solid experience working with hosted APIs (OpenAI, Gemini) and self-hosted models (Mistral, Ollama, LLaMA).
• Deep understanding of LLM orchestration, agent tool-use, memory sharing, and prompt engineering.
• Hands-on experience with Google Cloud Platform; especially Vertex AI, Cloud Functions, Cloud Run, and Pub/Sub.
• Familiarity with best practices in cloud-based software development: containerization, CI/CD, testing, and monitoring.
• Degree in Computer Science, Engineering, or a related field.
• Experience with machine learning, deep learning, NLP, and computer vision.
• Proficiency in Python, Java, and R.
• Strong knowledge of AI frameworks such as TensorFlow or PyTorch.
• Excellent problem-solving skills and ability to work in a team environment.

Nice to Have

• Experience with Google’s Agent Development Kit or similar agent ecosystems.
• Familiarity with multimodal AI handling text, image, audio, or video content.
• Prior experience developing creator platforms, content recommendation engines, or social media analytics.
• Understanding of ethical AI principles, data privacy, and bias mitigation.
• Experience with observability tools like Sentry, OpenTelemetry, or Datadog.
• Data engineering experience, such as building ETL/ELT pipelines, working with event-based ingestion and structured logs, using tools like BigQuery, Airflow, or dbt, or designing feature stores for AI/ML applications.

Technical Stack

• Frameworks & Tools: LangGraph, LangChain, Google’s Agent Development Kit, FastAPI, Streamlit, PyTorch, Transformers, FAISS, Pinecone, Weaviate, TensorFlow, BigQuery, Airflow, dbt.
• Models: OpenAI, Gemini, Claude, Ollama, Mistral, LLaMA.
• Cloud Platform: Google Cloud Platform, Vertex AI, Cloud Run, Cloud Functions, IAM, Pub/Sub.
• Languages: Python, Java, R.
