Join to apply for the Principal Product Designer role at Superduper

Who are we?

Superduper is building the future of decentralized finance and entertainment, creating Web3 products that millions will trust, engage with, and return to daily. Our diverse product suite spans trading platforms and gaming experiences, blending cutting‑edge blockchain technology with world‑class user experiences to set new standards for security, transparency, and engagement.

The Role

As Principal Product Designer, you will lead design across our Web3 ecosystem, from high‑stakes trading interfaces to immersive gaming experiences. You will define product experiences that make Web3 accessible, trustworthy, and compelling for users worldwide.

What You’ll Do
  • Lead design across our diverse Web3 product portfolio, ensuring each product maintains its unique identity while contributing to a cohesive ecosystem.
  • Set the quality bar as our Principal Designer, establishing design excellence across both financial and entertainment verticals.
  • Translate complex Web3 mechanics—wallets, transactions, smart contracts, provable fairness—into experiences any user can understand.
  • Partner with engineering teams to ship ambitious visions, balancing innovation with technical reality.
  • Create scalable design systems that flex across dramatically different use cases.
  • Design for the unique states and edge cases in both domains: transaction flows, gas optimization, cross‑chain interactions, game states, reward systems, social features.
  • Collaborate with blockchain engineers, quantitative developers, game developers, and compliance to meet diverse technical and regulatory requirements.
  • Champion user‑first design that excites traders and gamers alike.
  • Build and mentor a world‑class design team capable of delivering excellence across multiple product verticals.
Requirements
  • Proven track record of designing engaging digital experiences across multiple product categories, ideally in fintech/trading and/or gaming.
  • Senior‑level proficiency in UX, UI, and interaction design with a portfolio that shows range and adaptability.
  • Working knowledge of Web3 concepts (wallets, DEXs, smart contracts, NFTs) with ability to design intuitive abstractions.
  • Strong understanding of data‑driven interfaces and engagement‑driven experiences.
  • Strong prototyping skills for complex interaction patterns and real‑time data updates.
  • Experience leading design across multiple products or brands simultaneously.
  • Track record of working across the product development cycle from vision to execution.
Nice to haves
  • Experience in both fintech/trading and gaming/entertainment sectors.
  • Background in designing marketplace or ecosystem products that connect multiple user types.
  • Knowledge of DeFi protocols and blockchain gaming mechanics.
  • Experience with both B2C consumer products and sophisticated professional tools.
  • Track record of building and scaling design teams across verticals.
  • Understanding of regulatory requirements in finance and gaming.
What We're NOT Looking For
  • Designers who work exclusively in one vertical or style.
  • UX‑only designers without strong visual design skills.
  • Minimalistic aesthetics that cannot adapt to different contexts.
  • Designers focused only on B2B or enterprise‑only portfolios.
  • Designers who cannot create both analytical clarity and emotional excitement.
What kind of person succeeds in this role?
  • Hunter mentality: you believe anything can be achieved through tenacity and persistence.
  • Highly process‑oriented, balancing 10,000‑ft view and micro detail.
  • Thrives in a fast‑paced startup environment handling ambiguous concepts.
  • Builds strong relationships with internal and external stakeholders, delivering with confidence.
  • Handles intense, high‑pressure situations across multiple brands and regions.
  • Believes speed is a competitive advantage and drives urgency across the org.
