Staff AI Engineer

About the RoleOur client is hiring a Staff AI Engineer to lead the design and evolution of AI agents, with a focus on voice systems.This role is centered on building and operating AI agents that perform reliably in real-world environments. You'll own agent behavior end-to-end — from orchestration and tool use to latency, evaluation, and failure handling.You'll be working on complex, non-deterministic systems, designing the architecture needed to make them consistent, observable, and scalable in production.What You'll DoDesign and own AI agent architecture (orchestration, tool use, control flow)Build systems that enable agents to operate reliably across real-world interactionsDevelop and improve evaluation frameworks for agent quality and behaviorDebug and resolve complex production issues (edge cases, failures, regressions)Optimize performance across the stack (latency, cost, reliability)Define best practices for building and operating AI agentsMentor engineers and elevate AI systems design across the teamWhat We're Looking For7+ years of software engineering experienceExperience building and operating AI agents or conversational systems in productionAgent orchestration and tool useMulti-step workflows and control flowLLM behavior in real-world settingsExperience designing evaluation systems for AI qualityStrong debugging skills across complex, non-deterministic systemsNice to HaveExperience with voice systems (speech-to-text, text-to-speech, real-time pipelines)Experience building customer support agents or similar systemsExperience optimizing low-latency / real-time AI systemsExperience working across multiple model providers or inference stacks
