Principal Site Reliability Engineer

Job Description

As a Principal Site Reliability Engineer (IC4), you will be responsible for designing, building, and operating highly available, scalable, secure, and resilient cloud services. You will combine software engineering with infrastructure expertise to improve service reliability, operational efficiency, and developer productivity across large-scale distributed systems.

You will lead complex reliability initiatives, drive automation-first operational practices, and develop software solutions that eliminate manual toil. You will partner closely with software engineering, cloud infrastructure, security, and product teams to architect resilient platforms that meet aggressive availability, scalability, and performance objectives.

Success in this role requires deep expertise in distributed systems, cloud infrastructure, coding, automation, observability, incident management, and operational excellence. You will leverage modern AI technologies, machine learning, and intelligent automation to streamline operations, accelerate incident response, improve troubleshooting, and enable autonomous system management.

You are expected to be a technical leader who influences architecture, establishes engineering best practices, mentors other engineers, and drives continuous improvements across multiple services and organizations.

• Continuously optimize operational processes using data-driven insights.

Incident Management & Reliability

• Lead critical production incident response and act as a senior escalation point during major service events.

• Drive root cause analysis, corrective actions, and post-incident reviews with a focus on long-term engineering improvements.

• Develop automated remediation solutions to reduce Mean Time to Detect (MTTD) and Mean Time to Recover (MTTR).

• Continuously improve operational readiness through disaster recovery testing, game days, and failure injection exercises.

Performance & Scalability

• Identify performance bottlenecks across applications, infrastructure, storage, databases, and networking.

• Drive optimization initiatives to improve system throughput, latency, efficiency, and cost.

• Perform capacity planning and predictive scaling using historical trends and telemetry data.

• Optimize resource utilization while maintaining service reliability and customer experience.

Technical Leadership

• Serve as the technical leader for reliability engineering initiatives spanning multiple services and organizations.

• Establish engineering standards, architectural patterns, and operational best practices.

• Review system designs and influence technical decisions across engineering organizations.

• Mentor engineers on software engineering, distributed systems, cloud technologies, operational excellence, and automation.

• Drive engineering excellence through code reviews, design reviews, technical guidance, and knowledge sharing.

Innovation & Continuous Improvement

• Evaluate emerging cloud technologies, AI capabilities, automation frameworks, and observability platforms.

• Drive adoption of modern engineering practices including GitOps, Infrastructure as Code, continuous delivery, and policy-as-code.

• Identify opportunities to simplify architecture, eliminate operational complexity, and improve platform reliability.

• Champion engineering initiatives that increase service scalability, operational efficiency, and customer satisfaction.

Core Competencies

Planning & Execution

• Lead complex, cross-functional technical initiatives from design through production deployment.

• Balance reliability, scalability, performance, cost, and delivery priorities across multiple concurrent projects.
