React Jobs in Web3

Superis Labs is building a high-performance perpetual futures DEX on Solana. The first production MVP is underway, and early team members will define protocol UX/UI design.

The company is fully backed by ergonia, a crypto-native market-making firm with deep experience trading and building on Solana.

We are starting from a deliberately minimal core and iterating rapidly toward a full-featured mainnet exchange. This is a high-ownership role building production systems under aggressive timelines.

What You’ll Work On

Own the end-to-end design of a professional-grade perpetual trading experience. You’ll be the first dedicated design hire, shaping every interaction - from wallet connection and onboarding to order entry, position management, and portfolio views.

Responsibilities

• Design the core trading interface: markets, order entry, positions, balances, charts
• Create clear, intuitive solutions for complex trading workflows - margin, liquidation states, funding rates, P&L
• Build and maintain a scalable design system with reusable components and patterns
• Own the full design process from research and ideation through prototyping and production handoff
• Partner closely with frontend and protocol engineers to ensure high-quality implementation
• Produce detailed specs and documentation to guide development
• Review shipped work and QA design assets for quality and consistency
• Conduct user research to identify pain points and optimization opportunities
• Support the marketing team with brand assets

• 3+ years of product design experience with a strong portfolio
• Strong interaction and visual design skills with attention to detail
• Ability to take complex, data-heavy concepts and make them intuitive
• Proficiency in Figma (or similar) and components, shared libraries, auto-layout, prototyping
• Strong communication skills - able to articulate design decisions clearly
• Self-directed and comfortable in a fast-paced, early-stage environment
• Experience designing trading interfaces, orderbook UIs, or financial products
• Strong English communication skills

Bonus Points

• Understanding of perpetual futures, margin trading, or DeFi mechanics
• Experience with Solana or blockchain-based product design, including wallet flows
• Familiarity with how frontend technologies (HTML, CSS, React) impact design decisions
• Experience with motion design or prototyping tools like Framer (or other)

• No bureaucracy — just fast shipping and real impact
• High ownership and real impact from day one
• Competitive base + meaningful token/equity upside
• Early team members receive ownership aligned with long-term protocol success
• Fully remote
• IRL meetups and company offsites
