## About the role

Every AI agent's investigation is only as good as the LLM system underneath it. Get the retrieval, context, and prompting wrong, and the agent looks smart in a demo but falls apart on a real customer's data. As a Senior AI Engineer, you'll build the LLM-powered systems behind our security agents: retrieval workflows, context management, agent prompts, and structured output pipelines. This role is distinct from traditional ML engineering.

## What they're looking for

- 6+ years of software engineering experience, including at least 1 year building AI in production
- BS in Computer Science or a related field
- Shipped LLM applications in production, not just prototypes, using large models in ways that meaningfully mattered to the product
- Strong coding skills in Python (or equivalent), with experience in API design, backend integration, database systems, and cloud deployment
- Hands-on experience with RAG, vector databases (Pinecone, Weaviate), and workflow frameworks like LangChain or Dust
- Comfortable architecting end-to-end solutions, including context windows, caching strategies, tool calls, and multi-step reasoning
