Job description

Senior Lead Site Reliability Engineer

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 hands-on engineering role focused on designing, automating, and supporting highly available, mission-critical platforms. You will work at the intersection of distributed systems, cloud platforms, observability, and reliability engineering, helping to improve platform stability, performance, scalability, and operational efficiency.
• You will collaborate with engineering, development, and infrastructure teams to implement reliable solutions, automate operational processes, and resolve complex production issues while remaining deeply involved in the day-to-day technical work.
• The ideal candidate is a seasoned engineer with strong problem-solving skills, a passion for automation, and the ability to independently drive complex technical initiatives from design through production.

What you be doing

• Design and implement reliability architecture and engineering standards across services, platforms, and infrastructure, ensuring solutions are scalable, resilient, and operationally efficient.
• Design, build, and evolve enterprise-grade observability platforms (metrics, logs, traces, SLOs/SLIs) that provide actionable insights into system health, customer experience, and business impact.
• Implement and continuously improve SRE practices including error budgets, capacity modeling, resilience testing, graceful degradation, and operational readiness.
• Architect, build, and enhance automation and self-service platforms that eliminate toil, reduce operational risk, and enable safe, frequent production releases.
• Design, implement, and optimize CI/CD and release engineering solutions, including secure pipelines, deployment automation, quality gates, and rollback strategies.
• Troubleshoot and resolve complex production issues, performing deep root-cause analysis and implementing long-term reliability improvements.
• Collaborate with engineering, platform, and infrastructure teams to improve system reliability, scalability, performance, and operational excellence.

What You Bring

• 10 to 15 Years of IT Experience.
• Deep software engineering expertise with a proven track record of designing, building, and operating large-scale, distributed, API-driven systems in production.
• Strong CI/CD experience with tools such as Azure DevOps, GitHub Actions, Jenkins, Harness, or equivalent, including pipeline design, deployment automation, and release engineering best practices.
• 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.
• Hands-on experience across Linux (RHEL), Windows, databases (e.g. SQL Server, Oracle RDBMS), and complex enterprise technology stacks with strong troubleshooting and debugging skills.
• Strong experience designing and operating high-availability, mission-critical platforms with a focus on reliability, performance, scalability, and automation.

Added bonus if you have:

• Strong automation and scripting skills using Python, Bash, Ansible, PowerShell, or similar tools, with additional experience in C#/.NET considered a strong plus.
• 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.

What we offer you

• A multifaceted job with a high degree of responsibility and a broad spectrum of opportunities
• A modern, international work environment and a dedicated and motivated team
• A broad range of professional education and personal development possibilities FIS is your final career step!
• A competitive salary and benefits
• A variety of career development tools, resources and opportunities
