Site Reliability Engineering Senior Lead - 10+ Yrs - UK Shift - Pune Location

About The Role

We are hiring a Senior Lead Site Reliability Engineer to define, build, and operate always-on, low-latency, and highly secure payment platforms that power large-scale financial transactions.

This is a senior technical role, not a pure operations position. You will operate at the intersection of distributed systems engineering, cloud platforms, and reliability architecture, setting technical direction and driving reliability outcomes across mission-critical, regulated systems in Payments and FinTech.

You will work across multiple teams and domains, influencing architecture, engineering practices, and operational maturity while remaining hands-on with the most complex reliability challenges.

What You Will Do
- Own and drive reliability outcomes at scale for real-time, distributed payment and transaction processing platforms with strict SLAs, SLOs, and regulatory requirements.
- Define reliability architecture and standards across services, platforms,



and infrastructure—shaping how systems are designed, deployed, observed, and operated.
- Design and evolve enterprise-grade observability platforms (metrics, logs, traces, SLOs/SLIs) that provide actionable insights into system health, customer experience, and business impact.
- Lead and coordinate response to high-severity production incidents, acting as a technical authority during major events and driving deep root-cause analysis and long-term systemic fixes.
- Set strategy and drive adoption of SRE best practices including error budgets, capacity modeling, resilience testing, graceful degradation, and operational readiness.
- Architect automation and self-service platforms that eliminate toil, reduce operational risk, and enable protected, frequent production releases across teams.
- Partner with senior engineering, product, and platform leaders to influence architectural decisions, cloud migration strategy, disaster recovery
