About The Position

Quant is hiring a Lead Site Reliability Engineer to support a mission-critical blockchain platform underpinning The Clearing House's On-Chain Money Initiative, a next-generation payments network expected to launch in 2027. The role is based in Midtown Manhattan, New York City. The platform spans the OP Stack, private Besu L1 infrastructure, Overledger Gateway, and Settlement Bridge. The engineer will be the highest technical escalation point for the platform and will ensure reliability, scalability, and operational excellence across its distributed environment.

This is a hands-on technical leadership role for someone who wants to remain deeply technical rather than move into people management. The role helps shape reliability strategy, production standards, service ownership, release governance, and operational excellence, while participating in the shared on-call rotation for a 24/7 production environment. Applicants must be U.S. citizens; visa sponsorship and work authorization support are unavailable.

Requirements

• Extensive experience in Site Reliability Engineering, Production Engineering, or Platform Engineering within large-scale, mission-critical environments.
• Proven track record serving as the escalation point for high-severity production issues.
• Expert-level hands-on experience with Kubernetes, Terraform, Helm, cloud-native infrastructure, and container platforms.
• Deep understanding of distributed systems where consistency, consensus, and state management are critical.
• Strong experience driving operational excellence through monitoring, observability, automation, and incident response.
• Excellent documentation practices and a commitment to institutionalizing knowledge.
• Applicants must be U.S. citizens; the company is unable to provide visa sponsorship or work authorization support.

Nice To Haves

• Experience operating blockchain infrastructure in production environments.
• Hands-on experience with Ethereum ecosystem technologies, particularly Besu or other Ethereum clients.
• Understanding of blockchain consensus mechanisms and node operations.
• Experience troubleshooting blockchain protocol or client-level behaviors.
• Exposure to financial services, payments, regulated environments, or digital asset infrastructure.

Responsibilities

• Act as the senior technical escalation point for complex production incidents across blockchain and platform infrastructure.
• Lead reliability engineering practices, including incident management, root cause analysis, postmortems, and continuous improvement initiatives.
• Define and co-own SLOs, SLIs, error budgets, and release-gating standards.
• Design and improve monitoring, observability, alerting, and operational tooling.
• Partner with engineering teams to improve platform resilience, scalability, and performance.
• Drive infrastructure automation through Infrastructure-as-Code and platform engineering best practices.
• Develop and maintain operational runbooks, standards, and technical documentation.
• Mentor engineers and elevate operational maturity across the organization.
• Participate in a shared on-call rotation supporting a 24/7 production environment.
