Backend Engineer focused on AI Agents, Memory & Context

Responsibilities

• Your primary focus is Ask Vantum’s chat harness: the code and instructions that connect the model to conversation history, memory, app data, and tools.
• System prompts and model behavior. Write, test, and refine the instructions that govern how Vantum responds, uses context, asks questions, and calls tools.
• Resolve conflicting instructions and make behavior consistent across different requests.
• Context management. Decide what the model needs each turn, what to retrieve, and what to leave out. Preserve important information as conversations grow.
• Memory. Separate lasting preferences from temporary instructions. Handle corrections, outdated information, and deletions so the assistant remembers accurately.
• Queries and retrieval. Pull relevant tasks, goals, calendar entries, notes, and documents. Choose the right retrieval approach for the question.
• Tool execution.
• Build actions that validate inputs, enforce permissions, and handle failures without creating duplicate work or claiming something happened when it didn’t.
• Reliability and evaluation. Trace bad responses, reproduce failures, and verify improvements.
• Monitor response quality, latency, and cost while keeping client information properly scoped.
