Title and Summary

Senior Reliability EngineerOverview
The Service Management Reliability Engineering (SMRE) team plays a critical role in ensuring the reliability, compliance, and operational excellence of Mastercard’s Real Time Payments (RTP) platforms. The team operates at the intersection of product, engineering, operations, risk, and audit, acting as a trusted operational partner across highly regulated environments.
This role is essential to ensuring that RTP services transition safely from delivery into run, operate within defined service levels, and maintain a strong, audit‑defensible posture throughout their lifecycle.

Role
SMREs are custodians of the core operational processes that underpin service delivery and compliance for the RTP International programme. The role ensures that platforms are operated safely, changes are deployed with discipline, risks are actively managed, and operational artefacts remain accurate, current, and audit‑ready.
