Agent Design Manager

PolyAI automates customer service through lifelike voice assistants that let customers lead a conversation. Our voice assistants make it possible for businesses to deliver outstanding customer service that rivals their human agents. Our customers, which include the world's leading logos, are expanding how they use our platform, driving automation of critical customer service operations and integrating PolyAI into their daily customer service workflows.

We're looking for an Agent Design Manager to lead a multidisciplinary team of Agent Designers and Agent Design Engineers. This is a hands on leadership role for someone who sits comfortably at the intersection of conversational UX design and technical implementation - someone who thinks critically about how conversations should feel, not just how systems should work.

At PolyAI, Agent Design means owning the full picture: mapping user journeys, shaping dialogue and tone, and building the underlying systems that power them - prompting, tool access, and context engineering. If you've spent your career frustrated by the artificial gap between design and engineering, this role was built for you.

What you'll do:

Lead and develop your team

• Lead, mentor, and grow a team of Agent Designers and Agent Design Engineers, raising the bar on both design craft and technical execution
• Set clear objectives, provide thoughtful feedback, and support the professional development of every person on the team
• Foster a culture of curiosity, collaboration, and continuous improvement, with user centred thinking at its core

Own the quality of conversational experiences

• Act as the design authority for conversational UX across all agents - setting standards for tone, clarity, naturalness, and consistency
• Stay hands on with agent design and implementation, particularly on complex or high-impact projects
• Ensure every experience we ship feels intuitive and human, not scripted and robotic

Drive the discipline forward

• Guide the team through the full lifecycle: from user journey mapping and conversation design through to implementation - including prompting, tool integration, and context engineering - testing, and iteration
• Build and evolve processes that balance creative exploration with reliable delivery
• Partner closely with Engineering, Product, and Project Management to advocate for design quality throughout the development lifecycle
• Stay at the leading edge of agentic AI workflows - actively experimenting with new tooling and patterns, and bringing what you learn back into how the team builds

What we're looking for:

Required

• 5+ years in a technical or design adjacent role at a tech company, with genuine hands on experience - whether in conversational design, software engineering, or a combination of both
• 3+ years of people management experience, with a track record of developing designers and/or engineers into stronger practitioners
• Comfortable owning a team whose primary craft is conversation design - whether you come from a design background and have grown into technical depth, or an engineering background and have developed strong UX and language sensibility, you must be genuinely invested in raising the bar on both
• Proficiency in Python sufficient to read, review, and meaningfully engage with what your team ships - engineering background candidates should be comfortable going deeper
• Actively engaged with agentic AI workflows - you may not have shipped production multi agent systems, but you are experimenting hands on, forming opinions, and capable of leading your team into new patterns as the field evolves
• Meticulous attention to detail around language, consistency, tone, and interaction quality
• Clear, inclusive communication - able to translate between design and engineering contexts fluently

Preferred:

• Experience designing or deploying conversational AI assistants (voice or chat) using any platform or tooling
• Familiarity with LLMs in practice: prompt engineering, tool use, retrieval, context management
• Hands on experience with agentic frameworks or orchestration patterns - multi step reasoning, structured workflows, tool calling agents
• Experience with agile delivery practices - sprint planning, retrospectives, capacity management
• Experience managing external client relationships and stakeholder expectations

We offer competitive compensation based on experience, expertise, and the level of responsibility. This role also includes equity, giving you the opportunity to share in the long term success of the business.

The listed expectations reflect what we're hiring for, so we encourage you to review the job description carefully.
