Job Description

As an AI Engineer at Luupli, you will play a pivotal role in developing intelligent systems and orchestrating agentic workflows that power Luupli’s AI features. Your work will span Retrieval-Augmented Generation (RAG), multi-agent LLM orchestration, auto-captioning, generative media, and content moderation.

You’ll use frameworks like LangGraph, LangChain, and Google’s Agent Development Kit to build persistent, scalable AI services on Google Cloud Platform (GCP). This is a full-stack AI role that spans intelligent backend APIs, LLM agent orchestration, and integration with product-facing features.

Responsibilities

• 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 (e.g., FAISS, Pinecone, Weaviate).
• Integrate 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 GCP using Vertex AI, Cloud Run, Cloud Functions, IAM, and Pub/Sub.
• Embed AI into platform features such as auto-captioning, LuupForge (generative studio), feed personalization, and real-time moderation.
• Maintain modular, testable, observable, and secure code across the AI system lifecycle.

Requirements

• 3+ years experience in applied AI/ML engineering (production-level deployments, not research-only).
• Strong Python development skills with full-stack AI engineering experience:
• FastAPI, Streamlit
• LangGraph, LangChain, or similar
• PyTorch, Transformers
• FAISS, Weaviate, or 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 (GCP); especially Vertex AI, Cloud Functions, Cloud Run, and Pub/Sub.
• Familiarity with best practices in cloud-based software development: containerization, CI/CD, testing, monitoring.

Nice to Have

• Experience with Google’s Agent Development Kit or similar agent ecosystems.
• Familiarity with multimodal AI (e.g., handling text, image, audio, or video content).
• Understanding of ethical AI principles, data privacy, and bias mitigation.
• Experience with observability tools (e.g., Sentry, OpenTelemetry, Datadog).
• Working with event-based ingestion and structured logs (e.g., user sessions, reactions, feeds).
• Using tools like BigQuery, Airflow, or dbt.
• Designing or consuming feature stores for AI/ML applications.

Compensation

This is an equity-only position, offering a unique opportunity to gain a stake in a rapidly growing company and contribute directly to its success.

To Apply

Please send your resume and cover letter to [emailprotected] with the subject line: “AI Engineer”.

As part of your cover letter, please respond to the following questions:

• This position is structured on an equity-only basis. Thus, it is presently unpaid until we secure seed funding. Given this structure, are you comfortable continuing with your application for this role?
• Have you built or contributed to agent-based AI systems using frameworks like LangGraph, LangChain, or Google’s Agent Development Kit?
• Do you have experience with Retrieval-Augmented Generation (RAG) systems and vector databases (e.g., FAISS, Pinecone, Weaviate)?
• Have you deployed AI systems on Google Cloud Platform? If not, which cloud platforms have you used and how?
• Have you integrated LLMs (e.g., OpenAI, Gemini, Claude) into autonomous or multi-step workflows?
• Can you explain how agents collaborate and maintain memory across tasks in multi-agent systems?
• What is your experience with prompt engineering, tool invocation, and orchestrated LLM workflows?

Do you have any public code repositories (e.g., GitHub), demo URLs, or project write-ups showcasing your work? Please include links.

Requirements

• Degree in Computer Science, Engineering, or 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
