Protocol Engineering Lead

Cielo Projects; New York (NY); On-site; USD 175,000 - 230,000; Full time

Job summary

Quant seeks a Protocol Engineering Lead to own the production readiness of smart contracts and rollup architecture. You will coordinate external audits, manage the release train from development to deployment, and decide on upstream integration versus divergence, while communicating chain behaviour to reliability and security teams.

The role requires deep Solidity/EVM experience, experience with forks of large upstream codebases, and the ability to explain complex chain events to non-technical

Qualifications

• Deep Solidity and EVM experience with contracts that held real value and were audited.
• Strong understanding of rollup architecture beyond vocabulary.
• Experience maintaining a fork of a large upstream codebase and aware of costs over time.
• Ability to explain chain behavior to reliability engineers, security engineers and a bank.

Responsibilities

• Own protocol work from development to production release.
• Coordinate external audits for each release and address remediation.
• Decide what to take upstream vs. diverge on purpose.
• Explain unexpected chain behavior to non-engineering stakeholders.

Company Description

We're partnering withQuant, a global leader in digital transformation and technology solutions, seeking aPlatform Reliability Technical Leadto join their team.

About Quant:

Almost all the money in the economy is commercial bank money. Deposits, sitting on bank balance sheets, moving through payment systems designed decades before anyone had a reason to make money programmable. Almost none of it moves on chain.

Quant builds the infrastructure that changes that. Our technology lets a bank issue, move and settle its own money on programmable rails while staying connected to the systems it already runs on. That constraint is the reason this has taken as long as it has.

Central banks and commercial banks have built on our platform, including work on the digital pound and the digital euro. We are now building our team in New York.

Job Description

Protocol Engineering Lead

Most people who write smart contracts never have to keep them running afterward. This job is the other half.

Quant’s protocol work — permissioned EVM, rollup architecture, contracts that issue and settle regulated money — is moving from build into production. We want the person who owns it there. The release train from written to audited to deployed. External audit coordination on every release, and the remediation that comes back from it. The decisions about what we take from upstream, what we hold, and where we diverge on purpose.

You would also be the person who explains why the chain did something nobody expected, to people who are not protocol engineers. That is a larger part of the job than it sounds.

Qualifications

You will need

• Deep Solidity and EVM experience, on contracts that held real value and went through external audit.
• Real understanding of rollup architecture. The mechanics rather than the vocabulary.
• To have maintained a fork of a large upstream codebase, and to know what that costs over time.
• To be able to explain chain behavior to reliability engineers, security engineers and eventually to a bank.

Useful, not essential

• Permissioned or enterprise EVM deployments.
• Settlement, payments or tokenization rather than consumer applications.
• Public contributions. We will read them.
