Senior Site Reliability Engineer

About Quant
Quant builds interoperability and programmable payment infrastructure for banks, central banks and financial institutions. Our US delivery team runs mission-critical, distributed-ledger infrastructure for one of the largest payments organizations in the United States. We're hiring the engineers who keep it running, around the clock.

The role
Each shift has a Senior SRE as its senior technical anchor. You'll own the end-to-end reliability of our production environment while you're on shift. That environment includes OP-stack services, a private Hyperledger Besu L1, Paladin nodes, the Overledger Gateway, the Audit Store and the Settlement Bridge. You'll report to the Platform Reliability Technical Lead and work as part of a fully US-based team. There is no offshore handoff anywhere in the incident path.

What you'll do

• Act as the senior technical escalation point for your shift.
• Own observability, SLO instrumentation and error-budget tracking for your assigned production components.
• Lead incident response on shift, and drive post-incident hardening so issues don't recur.
• Join joint bridges with Security Operations on combined security-and-availability events.
• Mentor SREs on your shift, and set the standard for runbook discipline and clean shift handovers.

What you'll bring

• 6+ years in SRE, DevOps or production engineering.
• Strong cloud, infrastructure-as-code and observability tooling experience.
• Experience operating blockchain/DLT infrastructure is a strong advantage. That covers node operations, consensus and settlement systems.
• Willingness to work a rotating 24/7 shift schedule.

How we'll measure success

• Availability against SLOs.
• Incident recurrence rate.
• Quality of handovers between shifts.

Compensation and benefits

• Base salary: $95,000 – $130,000, depending on experience and skills.
• Annual Discretionary Company Bonus
• This role is overtime-eligible.
• 401(k) retirement plan.
• Medical, dental and vision coverage.
• PTO of up to 18 days per annum.
• Annual Personal Development allowance.

Start date: January 2027
