Senior Product Designer

Nivoda • Dover, NH

36d • $130,000 - $150,000 • Hybrid

About The Position

Nivoda is a fast-growing B2B marketplace transforming the global diamond and gemstone industry. We connect thousands of suppliers and retailers across 100+ countries, processing $300M+ in annual transactions. The gemstone industry is a $350 billion opportunity, and we're building the infrastructure to unlock it. We move fast, hire exceptional people, and give them real ownership over meaningful work. Great design is central to our mission to make the global gemstone market accessible to every business, regardless of size or location. We believe that how something works and how it feels are inseparable - and that the best product experiences create trust, reduce friction, and make complex things feel simple.

You'll be embedded in the Growth pod - one of the highest-priority, highest-visibility squads at Nivoda. The pod owns the levers that compound: acquisition, conversion, retention, and monetisation across the entire customer lifecycle. It's a team where design decisions show up in the growth dashboard the next morning. You'll work closely with Product Managers and engineers in the squad, and be part of a wider design team that cares about systems thinking, shipping fast, and making things people actually love to use.

As Senior Product Designer on the Growth pod, you'll own the design of some of the most important surfaces at Nivoda: the experiences that turn interest into revenue and keep customers coming back. From experiments that lift conversion to features that build lasting habits, your work will directly shape how the business grows. This is a role for a designer who's equally comfortable with a blank canvas and a complex system - someone who can go from a rough problem brief to a polished prototype fast, who cares about both pixels and patterns, and who sees collaboration with PMs and engineers as a creative multiplier, not a constraint.

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.

Nice To Haves

• 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.

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.

Benefits

• Competitive salary: $130,000 – $150,000 USD
• Private health insurance
• Unlimited holiday allowance
• Flexible compensation card (meals, transport, childcare)
• Opportunities for growth, learning, and career development
• The chance to join during an exponential expansion phase - and design experiences that reach buyers across 100+ countries
