Backend

The role

Mural, a visual collaboration platform, is hiring a Staff Backend Engineer for its remote-first AI Foundations team. The role builds the backend systems behind Mural's AI agent platform, including orchestration, memory and evaluation.

What you will do

  • Build core backend systems for the agent platform: orchestration, durable execution, tool execution, memory, observability and evaluation
  • Design services and APIs that let AI agents retrieve context and run multi-step workflows reliably
  • Develop the agent memory layer, covering conversation and product context, retrieval, summarization and compaction
  • Build tooling to monitor and improve agent behavior through traces, metrics, feedback and offline evaluation
  • Turn open-ended product needs into backend architectures, data models and plans
  • Help set technical direction for agentic AI and mentor others

What they ask for

  • 7+ years of software engineering building and operating reliable production systems and APIs
  • Experience with distributed systems for complex workflows: asynchronous processing, retries, event-driven design, failure recovery
  • Familiarity with LLM or agentic systems, such as tool use, context retrieval, evaluation or model orchestration
  • Strong focus on observability, reliability, testing, security and incident response
  • Clear technical writing and cross-team communication
  • Full-stack experience or close work with frontend teams
  • Deeper LLM evaluation, embeddings or retrieval experience is a plus
