Site Reliability Engineer

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.

As a Site Reliability Engineer, you'll be on the front line of our production environment during your shift. You'll handle monitoring, alerting and first-line incident response across OP-stack services, a private Hyperledger Besu L1, Paladin nodes, the Over ledger Gateway, the Audit Store, the Settlement Bridge and our observability stack. You'll work alongside a Senior SRE on every shift and report to the Platform Reliability Technical Lead.

The whole team is US-based, with no offshore handoff anywhere in the incident path.

• Monitor platform health, alerts and dashboards across production components, and acknowledge alerts within SLA.
• Respond to production incidents during your shift and help resolve them.
• Contribute to automation that reduces repetitive operational toil.
• Keep accurate shift logs and incident documentation.
• Escalate to the Senior SRE with complete diagnostic context.

• 3+ years in SRE, Dev Ops or production engineering.
• Working knowledge of cloud infrastructure and observability tooling.
• Exposure to blockchain or node operations is an advantage.
• Comfort handling incident response under time pressure.
• Willingness to work a rotating 24/7 shift schedule.

• Alert acknowledgement and response within SLA.
• Quality of incident documentation.
• Your contribution to automation and toil reduction.

You'll get hands-on experience operating production DLT and settlement infrastructure for a major financial institution. That experience is still rare in the market. You'll also have a senior engineer alongside you on every shift, and a clear progression path to Senior SRE.

• 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.
