About the role

  • The product only works if the agents are fast, reliable, and correct, not approximately correct.
  • Our stack: Go + Temporal for orchestration, a Plan-Execute-Synthesize agent architecture, and an evaluation harness we use to measure every regression.
  • Parallel agent DAG execution under hard latency budgets, streaming synthesis across partial sub-agent results, eval harnesses for non-deterministic multi-step systems: these are genuinely unsolved at production quality.

Responsibilities

  • What We're Building
  • Arcana is building AI agents that synthesize information across heterogeneous sources and deliver structured, reasoned answers in real time.
  • Drive TTFT below 400ms for multi-step agent pipelines
  • Design and implement Plan-Execute-Synthesize pipelines that run sub-agents in parallel DAGs, not sequential chains
  • schema design that LLMs actually follow reliably across providers

Requirements

  • You've built multi-step agent systems and you know where they break not from reading papers but from watching them fail in production
  • You've written eval harnesses from scratch and you have opinions about what makes a ground truth dataset actually useful
  • No cover letter required

Skills

  • LLM-as-judge pipelines for qualitative output assessment
  • Latency regression testing - p50/p95/p99 tracked across every deployment

Company info

  • A real-time AI product (search, coding assistant, chat at scale)
  • A model serving infrastructure company
  • An agent platform (any domain)
