Job description

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 paymentplatforms 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 safe, frequent production releases across teams.
• Partner with senior engineering, product, and platform leaders to influence architectural decisions, cloud migration strategy, disaster recovery posture, and long‑term platform evolution.
• Mentor senior engineers and technical leads, raising the overall reliability and operational maturity of the organization.

What You Bring

• Deep software engineering expertise with a proven track record of building and operating large‑scale, distributed, API‑driven systems in production.
• Expertise in observability, alerting, and reliability engineering, using tools such as Prometheus, Grafana, Datadog, Splunk, ELK, or equivalent ecosystems.
• Strong command of cloud platforms and open systems (AWS, Azure, or GCP), including infrastructure‑as‑code, platform automation, and cloud‑native design patterns.
• Significant experience running mission‑critical systems in Payments, FinTech, Banking, or similarly regulated environments, where availability, correctness, and security are non‑negotiable.
• Hands‑on experience across Linux (RHEL), Windows, databases (e.g., Oracle RDBMS), and complex enterprise stacks with strong system‑level troubleshooting skills.
• Demonstrated leadership in incident management, post‑incident reviews, and continuous reliability improvement, with the ability to influence behavior and standards across teams.
• Ability to operate effectively at Staff level scopesolving ambiguous problems, making trade‑offs, and driving alignment across multiple teams and stakeholders.

Added Advantage

• Strong automation and scripting skills using Python, Bash, Ansible, or similar tools.
• Experience building or scaling CI/CD platforms and release automation in high‑risk production environments.
• Prior ownership of reliability strategy or platform initiatives spanning multiple teams or business units.
• Experience modernizing legacy financial systems into cloud‑native or hybrid architectures with a focus on resilience and compliance.

Why Join Us

• Work on high‑impact payment platforms operating at massive scale, where milliseconds and reliability directly affect real‑world commerce.
• Play a Staff‑level role in defining reliability strategy for systems that cannot fail.
• Join a culture that values engineering excellence, technical leadership, automation, and continuous learning.
