Remote Status: Hybrid

🚀 Role Summary

• This role is a critical Individual Contributor (IC) position focused on driving product craft and execution excellence within a fast-paced, AI-first technology company.

• The Senior Product Designer will be responsible for end-to-end design ownership of high-impact product areas, with a strong emphasis on growth initiatives and the last 25% of product development that differentiates market leaders.

• The position requires a deep passion for interaction design, product thinking, and pixel-perfect execution, with the autonomy to drive impact without constant direction.

• Success will be measured by raising the design bar, shipping product with major business impact, operating autonomously, fostering positive engineer collaboration, and earning peer trust in design judgment.

📝 Enhancement Note: While the title is Senior Product Designer, the emphasis on "Growth" and "last 25%" of product development, coupled with the need to integrate AI into GTM strategies, positions this role to heavily influence Go-To-Market (GTM) operations through design. The ideal candidate will understand how design directly impacts user acquisition, activation, retention, and revenue growth, a key aspect of RevOps and Sales Ops alignment.

📈 Primary Responsibilities

• Own end-to-end design for high-impact product areas, from initial concept through to pixel-perfect execution, with a specific focus on growth-driving features and user flows.

• Define and implement new interaction patterns and design paradigms for Fin’s AI Agent, automation capabilities, and AI-powered tools, ensuring seamless integration and intuitive user experiences.

• Actively sketch, prototype, and conduct user testing at various fidelities to rapidly validate design decisions and iterate based on feedback, aligning with agile product development cycles.

• Collaborate closely with Product Managers (PMs) and Engineers to deeply understand problems, define solutions, move with speed and intensity, and deliver high-quality, reliable product outcomes that support growth objectives.

• Maintain exceptionally high standards of design craft and aesthetic quality, while expertly balancing the need for speed and efficient execution in a dynamic startup environment.

• Contribute significantly to the design team’s culture and growth, by mentoring junior designers, advocating for design excellence, refining design processes, and actively sharing knowledge both internally and externally.

• Champion AI-first design principles, exploring and defining how users interact with advanced AI capabilities to drive adoption and deliver tangible business value.

• Design for multiple surfaces and modalities, including desktop, mobile, chat interfaces, and emerging AI-driven experiences, ensuring a consistent and compelling user journey across all touchpoints.

📝 Enhancement Note: The responsibilities highlight a "maker" role, emphasizing hands-on design and prototyping over pure strategy. The focus on "growth" and "last 25%" implies a deep understanding of user psychology, conversion optimization, and the ability to translate business goals into design solutions that directly impact key GTM metrics.
