Mysten Labs’ mission is to advance the internet through step-function improvements in what technology makes possible. We build foundational infrastructure and products that give people, businesses, and developers new ways to interact, transact, and create value.

Our work spans on-chain finance and the emerging agent economy. Through Sui, Move, and our broader technology stack, we’re building the systems that make these experiences possible - from secure, scalable blockchain infrastructure to new ways for businesses and AI agents to interact.

Mysten Labs is looking for a Staff Product Designer to set the experience strategy for the DeepBook financial stack and the first-party products built around it, spanning spot trading, margin, prediction markets, liquidity, and the workflows that connect users and builders to onchain finance on Sui.

This role requires strong product judgment, exceptional design craft, people leadership, and real fluency in financial markets and DeFi. You will work with product and engineering from strategy through launch, build a design team that can cover a growing product surface, and stay close enough to the work to lead critical product flows yourself.

The right person knows how to make complex financial systems clear without removing the information users need to assess risk. You should be comfortable designing for retail and professional users, working through technical and regulatory constraints, and using research and product data to improve adoption, execution quality, retention, and trust.

What You Will Do

Set the design vision, principles, and priorities in partnership with product, engineering, and business leadership.

Own the end-to-end experience across DeepBook spot, margin, prediction products, liquidity workflows, and related first-party applications.

Lead the design of core journeys including onboarding, funding, market discovery, order entry, transaction review and signing, portfolio and position management, collateral, liquidation risk, settlement, and recovery from failed states.

Design for distinct audiences such as retail traders, experienced DeFi users, market makers, liquidity providers, institutions, and developers without creating a fragmented product experience.

Remain hands-on in the highest-priority work by framing problems, developing concepts, prototyping, testing, and reviewing implementation quality.

Build a scalable design system and shared interaction patterns for dense financial data, charts, tables, order entry, account states, alerts, and risk communication.

Establish a practical research program using interviews, usability studies, product analytics, support feedback, and market observation.

Partner with engineering to understand protocol behavior, transaction states, latency, data dependencies, security boundaries, and platform constraints.

Work with legal, security, marketing, business development, and ecosystem teams to launch products responsibly and communicate financial concepts accurately.

Define design and product quality measures, then connect the team's work to activation, conversion, trading success, retention, support burden, and user trust.

What You Will Have

10 or more years of product design experience, including meaningful experience leading, hiring, and developing designers in a fast-moving product organization.

A portfolio that shows both exceptional individual craft and leadership impact across complex, data-dense products.

Experience designing trading, investing, fintech, payments, crypto, marketplace, or other high-stakes products where users make consequential decisions.

Fluency in DeFi and direct experience using onchain products. You can discuss swaps, order books, liquidity, routing, slippage, collateral, leverage, liquidation, settlement, smart-contract risk, and transaction signing.

Strong product judgment and a record of shaping strategy, prioritization, and product decisions with product and engineering partners.

Skill in interaction design, information architecture, visual design, prototyping, research, and systems thinking.
