About the role
We are building a layered AI intelligence system a multi-layer agent architecture with a dynamic router context engine execution loop verification layer and eval feedback cycle designed to handle long-horizon business tasks that cannot be accomplished in a single model inference.
We are looking for engineers who understand that building with LLMs is not the same as building conventional software and who find that difference interesting not frustrating. You will own one or more layers of our AI system from design through production and iterate on them based on real-world failures.
What you will own
You will be matched to one of these layer areas based on your background and interest:
Context engine: design and operate the RAG pipeline memory architecture MCP tool integrations and prompt library that give the system company-specific knowledge at inference time
Execution loop: build the action-observe-act cycle tool integrations state management and logging infrastructure that let the system pursue multi-step goals
Verification layer: design the checker model confidence scoring and human escalation logic that prevents the system from committing to bad outputs
What we are looking for
13 years of experience building real systems that use LLMs not just calling an API but designing context handling failures and shipping to users
Strong software engineering fundamentals: you write clean testable code and you think about what happens when things break
Genuine curiosity about how LLMs behave: you have noticed patterns in how models succeed and fail and you have opinions about why
Ability to move quickly and iterate: we are building in a new space and the path forward involves learning from production
Nice to have
Experience with vector databases embedding models or retrieval systems
Familiarity with agentic frameworks: LangChain LlamaIndex AutoGen or similar
Experience designing prompts systematically treating prompt design as an engineering discipline
