Experienced (relevant combo of work and education) Senior Lead Site Reliability Engineer
Are you curious, motivated, and forward-thinking? At FIS you’ll have the opportunity to work on some of the most challenging and relevant issues in financial services and technology. Our talented people empower us, and we believe in being part of a team that is open, collaborative, entrepreneurial, passionate and above all fun.
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.
