ABOUT MATTER LABS

Matter Labs invented ZK rollups and built the first one on Ethereum: six years in production, over a billion transactions processed, over four billion dollars in value locked. We want programmable money to become a foundation for the next financial system, with institutions able to shape the services they provide and keep authority as their infrastructure evolves.

Prividium is our platform for institutions to build and operate digital asset businesses, with privacy and under their own rules. Prividium Commander is the control plane for digital asset services: an institution decides who can do what and tracks the resulting activity, on Prividium Ledger or on the chains it already runs. Prividium Ledger is a private blockchain with publicly verifiable execution. Prividium Connect gives institutions private, bridgeless transactions across blockchains.

Prividium Ledger runs in production for a number of institutional customers. Keeping those ledgers reliable, and making the next ten cheaper to operate than the first four, is the work this role is hired for.

Remote and global, few approvals, a CEO you can reach, unrestricted access to the best AI tools and the expectation that you use them, and a hiring bar of hell yes or no.

THE ROLE

You join the Production Unit, the three-person team that owns ZKsync OS in production for our customers: detection, incidents, rollouts and the service objectives each customer is measured against. Today the work is mostly reactive: on-call, incidents, rollouts, RCAs. The job is to change that. Every page and every manual step is a candidate for a fix in the server, a better alert or an automation. About 30 percent of your time goes to code now, and that share grows as the reactive load shrinks.

You own the environments you are assigned end to end: whether a change is safe to roll out, how an incident gets restored and explained, and whether the customer's service objectives are being met. Component teams own their code; you read it, find the cause, and land the fix.

WHAT YOU WILL DO:

•Run production for institutional customers. Hold the First Responder rotation, coordinate incidents to restoration, and write the RCA the customer's engineers read.

•Decide what ships. Go/no-go on changes to your environments, verification before rollout and validation after, including executing sequencer rollouts.

•Remove the cause. Turn pages, runbooks and manual steps into fixes in the sequencer, provers or tooling, so the same incident does not come back.

•Measure the service. Own the SLA card for your customers, measured monthly against their contracts.

•Finish across teams. Drive diagnosis and fixes through the component teams that own the code, without waiting to be asked.

•Later, support customers who run the chain themselves, where the fix has to work in someone else's hands.

Within a year, on-call load in your environments is measurably lower because of what you shipped, and the unit can take on the next customer without adding people.

WHAT WE LOOK FOR

•You have been on-call for a system you wrote code for, and you have owned an incident from page to RCA to the fix that stopped it recurring.

•You find causes in code you did not write. Strong in a systems language such as Rust, Go, C++ or Java; Rust is learnable here.

•You verify before you roll out and you can say which changes are reversible and which are not.

•You have run production for a service with external customers, and your incident notices and RCAs were read by their engineers.

•You make other teams finish the work without escalating.

•You are willing to hold a 24/7 rotation.

Nice to have: rollup or node operations experience (sequencer, prover, L1 settlement); Ethereum execution client internals; tooling you built that other teams adopted.

If you meet most of this and the rest is learnable, apply anyway.

NOT THIS ROLE

This is not a Forward Deployed Engineer role, which builds and deploys for a customer from discovery to production readiness; this role operates what is in production. It is not DevOps (clusters, network, L1 nodes, backups and disaster recovery stay with DevOps), not partner management, and not a people-management role.

COMPENSATION AND WORK MODEL

•Base salary range: USD 192,000 to 230,000 per year. Where an offer lands in the range depends on demonstrated scope and results against the bar described above. For candidates in the EU the same range applies

•Performance-based variable compensation and a long-term token incentive are additional.

•Benefits (employees): medical, dental and vision from day one, global health cover for team members outside the US; 401(k) with a Safe Harbor match up to 4 percent for eligible US employees, flexible paid time off plus public holidays and two company closure weeks a year; six weeks paid parental bonding leave plus up to ten weeks paid birth recovery leave; confidential mental health support; a USD 2,000 home office stipend, a company laptop refreshed every three years, up to USD 400 a month toward coworking, and a USD 500 annual learning budget; company and team offsites.

•Fully remote. You must be based in the US or the EU, with the US preferred; some of our customers whitelist the jurisdictions their operators work from, so this is a hard requirement.

•Full-time, as an employee or a contractor.

•24/7 First Responder rotation shared with the Production Unit. Everyone in this role is on it.

•We do not ask about your current or past pay at any stage of the process.
