Company Description We're partnering with
Quant , a global leader in digital transformation and technology solutions, seeking a
Platform Reliability Technical Lead to join their team.
About Quant: Almost all the money in the economy is commercial bank money, and almost none of it moves on chain. Quant is a leading provider of programmable money infrastructure, and our technology changes that: it lets banks issue, move and settle tokenized deposits around the clock, automatically and securely, while staying connected to the systems they already run on. It is already deployed in regulated environments with central and commercial banks in the UK and around the world, including work on the digital pound and the digital euro.
The Clearing House, whose networks clear and settle more than $2 trillion a day, has now selected Quant to power its On-Chain Money Initiative: a new interoperable payments network that will let financial institutions of all sizes clear and settle tokenized deposits, with connectivity to the RTP and CHIPS networks. Our technology provides the network's interoperability, orchestration and transaction-management layer, enabling payments that settle immediately and transactions that trigger automatically once agreed conditions are met.
Through our Tokenized Deposits-as-a-Service solution, banks of any size can join without building new infrastructure themselves. The network is expected to become available to participating institutions in the first half of 2027, with use cases across corporate treasury, liquidity management, cross-border payments and digital asset settlement. We are building the New York team that will run it.
Job Description Protocol Engineering Lead Most people who write smart contracts never have to keep them running afterward. This job is the other half.
The Clearing House has selected Quant to power its On-Chain Money Initiative, and the protocol work behind it, a permissioned EVM rollup on the OP Stack, is moving into production ahead of an expected launch in the first half of 2027. You would own the smart-contract release train, external audits on every release, and our diff against upstream Optimism: what we take, what we hold, and where we diverge on purpose.
You would also explain the chain's unexpected behavior to people who are not protocol engineers. The pool of people who can do this is small. If you are near the edge of it, apply.
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, ideally the OP Stack. 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.
Additional Information There is more to this than we can put in an advertisement. If it sounds like your kind of problem, apply and we will tell you the rest on a call.
