Senior Product Designer

Nivoda is a fast-growing B2B marketplace transforming the global diamond and gemstone industry. As a Senior Product Designer on the Growth pod, you'll own the design of key customer experiences that drive revenue and retention, collaborating closely with product managers and engineers.

Responsibilities:

• Own end-to-end design for growth surfaces across the customer lifecycle - working closely with the Growth PM to identify friction, run design experiments, and improve conversion, retention, and revenue
• Design growth loops and lifecycle experiences - referral mechanics, pricing and packaging surfaces, and features that compound usage across both sides of the marketplace
• Balance multiple workstreams and know when to go deep on craft versus move fast and ship
• Contribute to and maintain Nivoda's design system, ensuring consistency and quality across the pod and raising the bar for design coherence across the product
• Run lightweight user research - interviews, usability tests, and session reviews - to ground design decisions in real user behaviour rather than assumption
• Work directly with engineers to ensure designs ship accurately and at pace. You won't throw specs over the wall - you'll be in the build with them
• Use data and experimentation to validate design decisions: review funnel analytics, collaborate on A/B test design, and translate results into design iteration
• Communicate design rationale clearly to stakeholders - you can explain a decision in one sentence or a 10-minute presentation, depending on who's in the room
• Bring an AI-informed perspective to your workflow - whether that's using AI tools to accelerate ideation and prototyping, or thinking about where AI features can reduce friction for users
• Mentor more junior designers on the team and help build a culture of strong craft and feedback

Requirements:

• 5+ years of product design experience, with a portfolio that demonstrates strong UX thinking, high-fidelity UI craft, and measurable product impact
• Proven experience designing for complex, data-dense or catalogue-heavy products - marketplace, e-commerce, search, or similar
• Equally fluent in UX (flows, information architecture, usability) and UI (visual design, design systems, interaction detail)
• A track record of shipping fast in close collaboration with engineers - you're comfortable in a high-velocity environment and know how to make design decisions that don't block development
• Experience running or contributing to user research, and translating qualitative insights into design decisions
• Proficiency in Figma (or equivalent) and comfort working with or contributing to a component-based design system
• Strong communication skills - you can tell the story of a design decision as clearly as you can craft the design itself
• Based in or willing to commute to Boston regularly for in-person collaboration
• Experience designing growth surfaces - conversion, retention and lifecycle flows, referral loops, or pricing and monetisation - with a measurable impact on business metrics
• Familiarity with A/B testing tools and a working understanding of how to design for experimentation
• Experience using AI-assisted design tools (e.g. for rapid prototyping, content generation, or user testing)
• Background working at a B2B marketplace or two-sided platform
• Exposure to motion design or micro-interaction design
