Job summary

JPMorganChase is seeking a Lead Site Reliability Engineer to ensure the availability, performance, and resilience of production systems serving millions globally. You will embed reliability in the software lifecycle, guide cross-functional teams, and champion observability across monitoring and incident practices.

The role emphasizes leadership in incident response, SLOs, and tooling, with a focus on engineering excellence and scalable, secure operations in a financial services environment.

Qualifications

• Formal training or certification on site reliability engineering concepts and advanced applied experience.
• Hands-on experience designing and operating large-scale distributed systems with a strong focus on availability, fault tolerance, and performance.
• Proficiency in programming or scripting languages (Python, Go, Java, Bash) for automation and tooling development.
• Experience defining and managing service level indicators, service level objectives, and error budgets in production environments.
• Strong background in observability tooling, including metrics, logging, and distributed tracing platforms.
• Demonstrated experience leading incident response processes, conducting blameless post-mortems, and driving systemic reliability improvements.
• Experience with container orchestration and infrastructure-as-code practices (Kubernetes, Terraform, or equivalent).
• Ability to communicate complex technical concepts clearly to both technical and non-technical stakeholders.

Responsibilities

• Lead the design and implementation of scalable, reliable, and observable infrastructure solutions that meet the firm's availability and performance standards.
• Define and enforce service level objectives, error budgets, and reliability targets in partnership with engineering and product stakeholders.
• Drive incident response, root cause analysis, and post-incident reviews to identify systemic improvements and reduce mean time to recovery.
• Develop and maintain automation frameworks to eliminate toil, improve deployment pipelines, and accelerate delivery velocity.
• Collaborate cross-functionally with software engineering, architecture, and security teams to embed reliability and resiliency principles early in the design process.
• Champion observability practices by building and maintaining monitoring, alerting, and dashboarding solutions that provide actionable insights into system health.
• Mentor and guide junior engineers, fostering a culture of continuous learning, operational discipline, and engineering excellence.
• Evaluate and influence platform and tooling decisions to ensure alignment with reliability, scalability, and security requirements.
• Leverage enterprise-authorized AI-assisted engineering practices to improve operational outcomes, including incident triage support, test strategy acceleration, and delivery workflow optimization, while ensuring consistent validation and secure handling of inputs and outputs.
