Senior Software Engineer, Production

Accountabilities: Operate production blockchain environments for institutional customers, participating in the 24/7 First Responder rotation and coordinating incidents through to service restoration. Lead incident investigations, communicate updates to customers, and prepare detailed root cause analyses (RCAs) that explain what happened and how recurrence will be prevented. Make go/no-go decisions for production changes, ensuring appropriate verification before deployment and validation afterward. Execute sequencer rollouts and oversee the safe release of changes across assigned environments. Identify and eliminate recurring operational problems by implementing fixes in the sequencer, provers, and supporting tools. Transform alerts, runbooks, and manual operational procedures into more reliable software, automation, and improved monitoring. Own service-level objectives for assigned customers, tracking performance against contractual SLAs and reporting results monthly. Investigate issues across codebases owned by different component teams, identify root causes, and drive engineering fixes through to completion. Support the evolution of production operations so that additional institutional customers can be onboarded without proportionally increasing operational headcount. As the platform develops, help support customers operating their own chains, ensuring solutions can be implemented and maintained in external environments. Requirements: Experience being on call for a system you have contributed code to, with ownership of incidents from the initial alert through root cause analysis and implementation of a lasting fix. Strong software engineering skills in a systems-oriented programming language such as Rust, Go, C++, or Java. Rust experience is useful but can be developed on the job. Ability to investigate and understand code written by other engineers, identify underlying causes, and deliver effective fixes. Experience operating production services used by external customers, including communicating incident updates and writing RCAs for customer engineering teams. Sound judgment when managing production changes, including the ability to verify deployments and distinguish reversible changes from those that are difficult or impossible to roll back. Proven ability to coordinate across engineering teams and drive issues to resolution through influence and technical ownership. Willingness and availability to participate in a shared 24/7 First Responder rotation. Nice to have: Experience operating blockchain rollups or nodes, including sequencers, provers, or Layer 1 settlement systems. Nice to have: Familiarity with Ethereum execution client internals. Nice to have: Experience building internal tools or automation that have been adopted by other engineering teams.
