At the core of the role

We are looking for a Senior AI Engineer / Founding Engineer to build end-to-end AI systems in a fast-moving R&D environment.

The role spans the full engineering lifecycle - from scraping and ingesting massive geological datasets, through orchestrating AI agents, to rendering 3D insights in the UI.

You will work on AI/ML system design, agentic workflows, backend development.

Core skills you'll bring

• ML Leadership Experience - ability to review business problems, define AI/ML designs, and provide technical direction beyond agents and LLMs.
• Agentic Orchestration - strong experience with frameworks such as LangGraph, LangChain, or similar.
• Multi-Agent Systems - ability to design multi-agent systems, including supervisor/worker patterns, orchestration flows, and state management.
• Generative AI & LLMs - hands-on experience with LLMs such as Gemini, Anthropic, OpenAI, or similar.
• RAG - strong understanding of RAG architectures, retrieval optimization, embeddings, semantic search, context handling, and prompt design.
• Function Calling & Tool Usage - experience with function calling and external tool usage.
• Vector Databases - experience with vector databases such as Vertex AI RAG Engine, Pinecone, FAISS, or similar.
• Python & API Development - strong Python skills and experience building APIs using FastAPI or similar.
• Async Programming - understanding of asynchronous programming and handling long-running processes.
• Data Modeling & Validation - experience with Pydantic or equivalent frameworks, including the ability to design structured inputs and outputs for AI systems and APIs.

The impact you'll create

• Build end-to-end AI systems spanning large-scale geospatial data scraping/ingestion, multi-agent backends, and responsive 3D web interfaces.
• Build end-to-end systems spanning scraping and ingesting massive geological datasets, orchestrating AI agents, and rendering 3D insights in the UI.
• Develop AI systems using LLMs, RAG architectures, vector databases, embeddings, semantic search, function calling, and external tools.
• Build performant Python/FastAPI backends using asynchronous programming and supporting long-running processes.
• Design structured and validated inputs and outputs for AI systems and APIs.
• Work independently in R&D / POC environments and adapt to rapidly changing priorities.
• Apply strong problem-solving and ownership skills to rapidly evolving AI/ML challenges.
