Staff AI Engineer

About the Role

Our 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 Do

• Design and own AI agent architecture (orchestration, tool use, control flow)
• Build systems that enable agents to operate reliably across real-world interactions
• Develop and improve evaluation frameworks for agent quality and behavior
• Debug 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 agents
• Mentor engineers and elevate AI systems design across the team

What We’re Looking For

• 7+ years of software engineering experience
• Experience building and operating AI agents or conversational systems in production
• Agent orchestration and tool use
• Multi-step workflows and control flow
• LLM behavior in real-world settings
• Experience designing evaluation systems for AI quality
• Strong debugging skills across complex, non-deterministic systems

Nice to Have

• Experience with voice systems (speech-to-text, text-to-speech, real-time pipelines)
• Experience building customer support agents or similar systems
• Experience optimizing low-latency / real-time AI systems
• Experience working across multiple model providers or inference stacks
