Ellipsis Labs is a profitable, venture-backed New York-based startup building differentiated products and infrastructure in decentralized finance.

The company is the developer of Phoenix, the leading order book spot exchange on the Solana blockchain, and a top 10 DEX (decentralized exchange) with >$70B in volume since inception in 2023. Additionally, we are one of the most active and prominent on-chain market makers in crypto.

All roles are in the Ellipsis Labs office in New York City.

Ellipsis Labs is seeking a Senior Designer to define and elevate the visual language of our exchange and brand across high-density, real-time trading interfaces. You’ll partner with engineering and leadership to craft a cohesive, trustworthy look and feel - from component libraries to data visualization, motion, and launch assets. In this role, you will:

• Own the visual system for Phoenix and future products: typography, color, spacing, iconography, design tokens, and component theming

• Turn complex trading mechanics and data into clear, scannable visual hierarchies and data visualizations that perform under real-time constraints

• Build and maintain a Figma library/design system, ensuring consistency and speed of implementation; provide developer-ready specs and assets

• Drive visual polish on critical surfaces (order entry, positions, charts, risk states), including loading/empty/error states and micro-interactions/motion

• Partner closely with engineers to ensure visual fidelity in production and pragmatic choices under technical constraints

• Own the company and product brand expression across product surfaces and key moments

• Incorporate feedback, user signals, and metrics to iterate quickly without sacrificing craft

Qualifications

Required

• 2+ years designing visual systems for complex digital products, ideally high-density or data-heavy (trading/finance, analytics, dev tools, etc.).

• Portfolio demonstrating strong visual craft (type, color, layout), system thinking (tokens/components), and clear data presentation.

• Fluency in Figma (components/variants, auto-layout) and handoff practices; attention to detail across states and edge cases.

• Comfort collaborating with engineers; ability to balance visual quality with performance and feasibility.

• High ownership and bias to ship; you sweat the details and move quickly.

Preferred

• Familiarity with crypto/Web3 design patterns and user behaviors

• Exposure to Solana or similar blockchain ecosystems
