Responsibilities

  • 01Design and build across the Otto platform, including the runtime and agent graph, the tool/action layer, the Rails/GraphQL backend, and the advocate-facing experience, owning a meaningful slice end-to-end
  • 02Expand what the agent can safely do: autonomous, tool-using actions with human-in-the-loop approval, built on a secure, auditable identity and permissions model
  • 03Build the eval and observability systems (LLM-as-judge + deterministic scorers, offline gates and online production monitoring) that let us change the agent in production weekly without regressing correctness or escalation behavior
  • 04Work directly with LLMs, including prompting, tool/function design, retrieval, and the feedback loops that turn real advocate interactions into a better Otto
  • 05Partner closely with Product, Data, Design, and our CX teams to turn advocate and customer pain into shipped capabilities
  • 06Mentor engineers and set the bar for how we build agentic systems responsibly and at scale

Requirements

  • 01Typically 8+ years of software engineering experience, owning systems end-to-end
  • 02You've built and shipped LLM-powered or agentic systems in production, including tool-calling/agents, retrieval, or evals, and you know where they break and how to make them reliable
  • 03Strong full-stack range. Must be comfortable moving between backend services, an LLM runtime, and customer-facing product, and picking up whatever the problem needs
  • 04Experience owning multi-quarter projects that make measurable user impact at scale
  • 05Sound judgment about safety and blast radius when software takes real actions on real accounts
  • 06Ability to mentor engineers and raise the bar around you
