Senior Software Engineer, Production - Matter Labs

About Matter Labs

Matter Labs invented ZK rollups and built the first one on Ethereum. We are dedicated to making programmable money the foundation of the next financial system. Our platform, Prividium, enables institutions to build and operate digital asset businesses with privacy and control.

The Role

You will join the Production Unit, a three-person team responsible for ZKsync OS in production. This role is focused on moving from reactive work (on-call, incidents, RCAs) to proactive engineering. You will own your assigned environments end-to-end, diagnosing issues, landing fixes, and automating manual processes. Approximately 30% of your time is spent on code, with that share increasing as reactive load decreases.

What You Will Do

• Run production: Hold the First Responder rotation, coordinate incident restoration, and write RCAs.
• Control rollouts: Manage go/no-go decisions for changes, including sequencer rollouts.
• Drive reliability: Turn manual steps and runbooks into automated fixes within the sequencer, provers, or tooling.
• Measure performance: Own the SLA card for customers, ensuring service objectives are met.
• Collaborate: Drive diagnosis and fixes across component teams without waiting for requests.
• Scale: Enable the unit to support new customers without increasing headcount.

What We Look For

• Experience being on-call for systems you wrote code for, owning incidents from page to RCA to permanent fix.
• Ability to find causes in code you did not write; strong proficiency in a systems language (Rust, Go, C++, or Java).
• Experience running production services for external customers.
• Ability to drive cross-team work without escalation.
• Willingness to hold a 24/7 rotation.
• Nice to have: Experience with rollup/node operations (sequencer, prover, L1 settlement) or Ethereum execution client internals.

Compensation and Work Model

• Salary: $192,000 – $230,000 base salary (US and EU).
• Incentives: Performance-based variable compensation and long-term token incentives.
• Benefits: Comprehensive health coverage, 401(k) with match, flexible PTO, parental leave, mental health support, home office stipend, equipment refresh, coworking allowance, and annual learning budget.
• Location: Fully remote. Must be based in the US or EU.
