How We Work
Our hybrid work style (3 days in the London office) gives us the face-to-face time to have creative conversations, meaningful meetings, make quick decisions and build relationships. And it’s flexible enough to give you the space to do your best work.

About the Role
As a Staff AI Conversation Designer, you will shape how our AI Assistant thinks, speaks, and acts, defining the conversation flows, prompt structures, and behavioral standards that make agentic AI experiences feel trustworthy, capable, and human-centered. You will join the AI Assistant team, a platform team that builds agentic capabilities that plug into each of Gen's brands, including Norton and Avast. This is a hands-on, high-autonomy role. You'll be expected to self-organize, set direction with minimal oversight, and run the day-to-day rhythm of the work, including sprint planning and prioritization alignment with engineering and product, while your manager focuses on the quality and outcomes of the work rather than the day-to-day process.

Key Responsibilities

• Own the conversation and model design vision and strategy for the AI Assistant pillar, driving the design of dialogue flows, prompts, and behavioral guardrails across the assistant and its agentic capabilities.
• Design, test, and iterate on conversation flows, prompt structures, model persona and tone, error and fallback handling, and multi-turn interaction patterns for an AI assistant with agentic capabilities.
• Partner directly with backend engineers to translate conversation and model design decisions into implementation, reviewing model outputs and agent behavior for quality, safety, and consistency.
• Partner with Product Managers to shape the roadmap, drive prioritization alignment, and represent conversation design in sprint planning, backlog grooming, and other agile ceremonies, largely without close oversight.
• Apply systems thinking to build reusable conversation frameworks, prompt libraries, and evaluation criteria that scale as the assistant's capabilities grow.
• Shape best practices for agentic AI experiences, ensuring they are understandable, trustworthy, and consistently adopted across teams.
• Validate conversation and model design decisions, measure impact, and continuously evolve the assistant's behavior based on evidence.
• Act as the design lead for the AI Assistant platform team: Own UX decisions for the assistant's experience, partnering with backend Engineering and Product Management.
• Partner with each brand's product and design teams (for example Norton and Avast) to ensure the assistant's conversation and behavior integrate well with the UI each brand owns.
• Operate autonomously: self-organize priorities, resolve ambiguity, and lead cross-functional alignment with minimal day-to-day direction, escalating only where scope or quality decisions require input.
