Senior Site Reliability Engineer (SRE III)

About the role

As a Senior Production Engineer you will be the single point of accountability for the operational health of a key business service or payment flow. You will protect its reliability budget, own its controls evidence, and translate ticket closures into client‑impact outcomes for executive stakeholders.

Key responsibilities

• Own end‑to‑end operational health of a named service portfolio, accountable for availability, MTTD, MTTM, MTTR and client‑impact trends against published SLOs and error budgets.
• Defend the reliability budget and make change‑governance decisions based on budget consumption rather than ticket urgency.
• Lead incident, problem and change management for full‑stack payment systems, escalating cross‑functionally and presenting client impact to executives.
• Own controls and regulatory evidence (patch compliance, certificate expiry, vulnerability aging, EOL exposure) and drive automation of evidence collection.
• Convert manual, repetitive work into automation, measuring hours removed and capacity returned.
• Partner with application development and central SRE/observability teams under a shared reliability services agreement.
• Build depth of coverage on owned services, eliminating single‑person dependencies and naming backup owners.

Required profile

• 5+ years operating payment or financial‑services production systems with named accountability for service availability.
• Demonstrated ownership of SLOs, error budgets or equivalent reliability engineering discipline in a large‑scale, regulated environment.
• Working knowledge of payment flows (authorization, clearing, settlement, billing, payment/rebate) and their client and regulatory impact.
• Experience partnering with controls, risk and audit functions on production evidence and regulatory findings.

Required skills

• Experience with observability/monitoring tooling.
• Automation or scripting for toil elimination.
• Familiarity with AI‑assisted operations such as RCA, ECC and runbook automation (preferred).
• Understanding of formal SRE/reliability operating models (preferred).
