Come join our growing team at Cubist as we open the funnel for 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 create the framework for connecting those customers with the product that automates 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 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 EigenLayer, Babylon, 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 has shown excellent cross-selling within existing accounts.

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 build out our GTM function.

About the Head of Sales Role:

As Cubist’s first dedicated GTM hire, you will work directly with the founders to formalize our sales playbook, grow a run-rate business, and build meaningful long-term customer relationships. We’re looking for someone who is a strong listener, relationship builder, and communicator relentlessly focused on uncovering and solving customer needs. You will start as a direct seller focused on signing new logos and be responsible for the entire funnel from leadgen to closing. As we transition from founder-led sales, you will put processes in place to prepare us to hire and train additional sellers. We’ll count on you to be very systematic in your approach to outreach and selling so you can be an effective feedback loop to marketing, product, and engineering teams.

Qualifications:

You must have a track record of success selling six-figure+ contracts to enterprise companies, with at least some of that experience at a B2B startup. You’ll have an advantage in this role if you have experience selling Web3 infrastructure, especially if related to custody, wallets, payments, and/or tokenization—and familiarity with the Web3 security landscape. You don’t need to know how to code, but you should be unafraid of technical detail and comfortable selling to technical buyers. To thrive at Cubist, you should be happy working cross-functionally and collaboratively. We anticipate most qualified candidates will have eight or more years of related experience.

Tasks and Responsibilities:

• Own the sales process from lead generation to closing

• Generate pipeline and qualify leads

• Maintain strong relationships after closing to drive renewals and cross-sells

• Develop and execute sales strategies in collaboration with leadership

• Accurately forecast revenue based on previous quarters

• Provide structured feedback to other teams to inform product messaging and roadmap

• Define an AE spec and help us hire new sales talent as the company grows

Bonus:

• Prior experience selling to banks, fintech, or other financial institutions

• Prior experience with business development, marketing, customer success, product management, or other functions that touch sales

• Interest in attending conferences and industry events

• Capability to hire and manage a team of sellers as Cubist grows

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 go after a hot market with a young product already seeing traction from banks and other serious institutions. 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!
