Product Designer, Growth (Staff/Principal-level)

About the role

As a (Staff/Principal-level) Product Designer joining our Growth team, you will operate at a high-impact, senior individual contributor level, partnering directly with a Product Manager to meaningfully influence Synthesia's growth engine. This role sits at the center of how users experience Synthesia for the first time. Your work will directly impact two core metrics: Activation: % of users who experience value and develop a habital use of Synthesia Longer Term Retention - Increasing the proportion of users who embed Synthesia into their day-to-day workflows and continue using it as a core part of their toolkit over time. You will focus on rethinking and reshaping high-impact user journeys, particularly onboarding, first-time editor experiences, and early product exploration. Expect to work on problems such as: Reducing cognitive overload during onboarding Redesigning first-time editor experiences to balance guidance with creative power Designing around AI latency and uncertainty states inherent in generative systems Solving cold-start challenges in an AI creation product These are structurally complex problems, not incremental improvements. Within the team, ideas move quickly from concept to functional prototype. Designers are not the only ones prototyping. PMs use tools like Lovable and Claude Code to generate working code in sandboxed environments. Your role is not to simply polish these outputs - it is to rethink, restructure, and elevate them into coherent, scalable experiences. You will shape how ambiguous ideas become testable product directions and how early experiments evolve into durable solutions. You will operate as a true partner in a PM-design-engineering trio, influencing problem framing, experimentation strategy, and solution direction from first principles through execution.

Responsibilities

• Reimagining onboarding and early editor workflows to materially improve activation
• Translating ambiguous growth and product challenges into clear concepts, flows, and working prototypes
• Partnering with Product and Engineering to move core growth metrics
• Challenging briefs, assumptions, and existing interaction patterns
• Elevating AI or PM-generated prototypes into scalable, thoughtfully designed experiences
• Designing experiments that help the team learn quickly, knowing not every concept will ship
• Contributing to critique culture and raising the bar for product thinking across the Growth team
• Coaching and mentoring designers where relevant

Requirements

• You have operated at a high level of scope and autonomy, influencing product direction beyond surface-level design decisions
• You think in terms of metrics and outcomes, not just flows and artifacts
• You are comfortable being accountable for moving activation and adoption in a self-serve business
• You thrive in experimental environments where many ideas are discarded and speed matters
• You are comfortable working in AI-native workflows where PMs and engineers prototype alongside you
• You consistently ground your design decisions in both qualitative insights and quantitative data, clearly articulating how these inputs shape your solutions.
• You can collaborate directly with engineers, understand constraints, and design within (or intelligently push against) them
• You are energized by complex, zero-to-one challenges where the right solution is not obvious
• Our culture
