Business Development Lead (Protocol Partnerships)

Cubist

About The Position

Join Cubist as we solve the most critical infrastructure challenge in Web3: securing the protocols and bridges that power the blockchain ecosystem.. For Layer 1s, L2s, bridges, and other protocols non-custodial, scalable key management is critical. CubeSigner protects the most sensitive keys with decentralized multi-party signoff and governance policies; our Confidential Cloud Functions allow protocols to run sensitive logic verifiably but off-chain—in a “private smart contract”. We are looking for a Business Development Lead (Protocol Partnerships) to own the commercial lifecycle for our ecosystem vertical. You will bring C2F and CubeSigner to protocol teams, helping them build features that were previously impossible on-chain. You’ll report to the President and work directly with the builders of one of the most advanced digital asset platforms in the industry. This is a full-cycle role for a commercial operator who understands blockchain infrastructure. You will spearhead Cubist’s expansion into L1/L2 ecosystems, targeting Foundations, Labs, and DePIN networks. You will act as a consultative partner to Protocol Founders, Heads of Ecosystem, and Core Devs. You will move the relationship from "governance proposal" or "grant discussion" to embedded infrastructure.

Requirements

You speak the language of protocols. You understand consensus mechanisms, slashing conditions, and the difference between a sequencer and a validator.
Experience: 7+ years in business development or partnerships within crypto, specifically dealing with Foundations, L1s, or infrastructure.
Network: You have direct lines to leadership at top protocols and arguably more importantly, the dev shops that build on them.
Technical Fluency: You can confidently discuss high-level staking architectures, MPC vs. HSMs, and distinct signature schemes (eg., BLS, Ed25519).
Closer Mentality: You don't just "do BD" for brand awareness; you drive revenue and adoption metrics.

Responsibilities

Build and manage a high-quality pipeline of L1/L2 foundations, other protocols, bridge operators, and rollup-as-a-service providers. Identify networks where Bascule (our bridge security product),C2F private smart contracts, and CubeSigner can solve latency, security, or privacy issues.
Work with protocol teams to map how CubeSigner can secure everything from governance keys to bridges to validators.
Collaborate with Engineering to scope integrations that prove technical value.
Lead commercial negotiations for foundation grants, service agreements, and partnership incentives.
You will own the relationship post-signature, ensuring deep integration into the protocol's developer docs and recommended tooling stack.
