Come join our growing team at Cubist to help us enhance the usability of CubeSigner, our secure key management platform that lets institutions, DeFi protocols, and Web3 projects easily interact with digital assets without cutting corners on security. The status quo is downright crazy: In 2023 alone, nearly $700M was stolen across the industry due to mismanaged secret keys. The problem is only getting worse as we see government entities and Web2 companies without crypto expertise start to explore how blockchains can simplify manual processes and provide new ways to engage with mainstream masses.

As Web3 gains mainstream traction—from the finance industry to retail and beyond—our solution is poised for lucrative, exponential growth: it’s the only product with the technical foundation to meet tomorrow’s customers’ needs. You will lead the design of the web interface those customers use to manage secure transaction signing for staking, tokenization, consumer wallets, and other blockchain-based projects where security, speed, reliability, and extensibility all matter. Help build a world where no one has to use a hot wallet to make a great product or use a complex and cumbersome cryptographic protocol to ensure security!

About the Cubist Product:

CubeSigner eliminates the tradeoff between security (keeping keys safe from attackers), performance (keeping keys available for use), and convenience (keeping keys hidden from end-users) that teams have long had to make when working with digital assets. Trading teams today, for example, resort to sharing hot wallets containing millions of dollars to meet low latency deadlines; consumer apps roll out questionable custody practices just to make social logins work; and investors scatter assets across platforms and USB sticks because staking or trading is a risky bespoke exercise. CubeSigner provides 1) a secure design rooted in mature, battle-tested hardware; 2) 100x better speed than competing solutions; 3) extreme reliability without correlation to market events; and 4) safe extensibility to add new features without impacting security.

We launched CubeSigner as a developer API one year ago with the goal of making DeFi access safer and easier. We remain focused on bringing liquidity into DeFi through our partnerships with Babylon, EigenLayer, and liquid staking protocols, and more broadly, making Web2 and Web3 interoperable in ways that feel familiar to the mainstream. Our early key management customers include Ankr, Ava Labs, and Sports Illustrated Tickets. Because a key mediates everything a company does in Web3, CubeSigner is a critical part of every customer’s technology stack and serves as a collaboration point between many teams and functions. The MVP version of CubeSigner’s web interface is currently in beta with select customers.

About the Cubist Team:

Cubist’s founders include a former fintech COO and professors from UC San Diego and Carnegie Mellon University, who have published over 80 papers on computer security. Members of the Cubist team have designed and specified the cryptography underlying Ethereum and Avalanche, deployed fine-grained isolation in Firefox, discovered serious bugs in Google Chrome and Linux, and built the automated reasoning tools that companies like Amazon and Certora rely on. We are well funded with more than two years of runway from Polychain, dao5, Amplify, Paxos, and other top-tier venture capital and strategic investors, and we’re excited to bring our design function in-house.

About the Staff Product Designer Role:

As Cubist’s first full-time designer, you will work directly with the founders and engineering team on a highly technical product that is used by Web3 teams to securely manage keys and assets. Given Web3's historically challenging UX, abstracting away complexity will be an important differentiator for our product’s success—so we’re committed to getting it right! We’re looking for someone with broad design skills and interests spanning visual design, software UI/UX, and user research. You will drive features from start to finish and work with other teams to measure the performance of your designs, then iterate on them so we keep improving for our customers.


You will have an advantage in this role if you have previous exposure to developer tools or SaaS platforms, as well as a firm understanding of the software development life cycle and developer personas. You must be a masterful storyteller who is skilled at using a combination of qualitative and quantitative data to distill complex workflows and make design decisions. To thrive at Cubist, you should be happy working cross-functionally and collaboratively. We anticipate most qualified candidates will have five or more years of professional UI/UX design experience.

Tasks and Responsibilities:

  • Web app UI/UX: Produce storyboards, wireframes, interactive prototypes and/or other design deliverables using an industry standard tool like Figma.

  • User flows: Synthesize user flows that reflect distinct user personas and deep understanding of the problems Cubist solves for each customer segment.

  • User research and testing: Participate in voice of the customer activities to gather requirements and feedback, and examine product usage data to understand key metrics around adoption and satisfaction.

  • Design reviews: Propose design solutions based on data, and work cross-functionally to determine the best path forward at various stages of the development process.


  • Experience writing TypeScript web apps

  • Visual design skills for creating sales and marketing collateral, company website, slide decks, etc.

  • Prior professional experience with Web3 and blockchains

Compensation & Perks:

  • Competitive salary, commission structure, and equity compensation

  • Comprehensive medical, dental, vision, and life insurance benefits

  • Company-sponsored 401(k)

  • Home office stipend

  • Company retreats

Why Cubist?

In this role, you’ll have a unique opportunity to lead the design process for a young product that is already seeing traction from banks and other serious institutions. You’ll also play a significant part in defining the future of Cubist’s design culture. Our team is curious, energetic, collaborative, ambitious—and fully remote—and we want to work alongside similarly bold and motivated individuals. If this sounds like fun, we’d love to hear from you!
