Senior Software Engineer, Production

About the role

Matter Labs, behind the ZK rollup Prividium, is hiring a Senior Software Engineer, Production for its three-person Production Unit that keeps ZKsync OS running for institutional customers. The work is remote and global, with a 24/7 First Responder rotation shared with the unit. The goal is to move from a mostly reactive, on-call and incident-driven workload to one where about 30 percent of time is spent on code, and that share grows.

Key responsibilities

• Run production for institutional customers, hold the First Responder rotation, coordinate incidents to restoration and write the root cause analysis (RCA) read by customer engineers.
• Decide what ships: go/no-go on changes, verification before rollout and validation after, including sequencer rollouts.
• Turn pages, runbooks and manual steps into fixes in the sequencer, provers or tooling so the same incident does not recur.
• Own the SLA card for customers, measured monthly against their contracts.
• Drive diagnosis and fixes through the component teams that own the code, and later support customers who run the chain themselves.

Required profile

• On-call experience for a system you wrote code for, owning an incident from page to RCA to the fix.
• Experience running production for a service with external customers, whose incident notices and RCAs were read by their engineers.
• Ability to find causes in code you did not write and to make other teams finish the work without escalation.
• Willingness to hold a 24/7 rotation.
• Must be based in the US or the EU (US preferred), as some customers whitelist operator jurisdictions.

Required skills

• Strong in a systems language such as Rust, Go, C++ or Java; Rust is learnable on site.
• Nice to have: rollup or node operations experience (sequencer, prover, L1 settlement), Ethereum execution client internals, and tooling you built that other teams adopted.

What we offer

• Base salary of USD 192,000 to 230,000 per year, with performance-based variable compensation and a long-term token incentive.
• Medical, dental and vision coverage 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, two company closure weeks a year, and six weeks paid parental bonding 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, a USD 500 annual learning budget and offsites.
• Fully remote, full-time, as an employee or a contractor.
