Job Description:

The Principal Site Reliability Engineer will be a senior technical expert responsible for driving end-to-end resilience, reliability, and scalability across our mission-critical payments platform. This role focuses on front-to-back payment flows, ensuring systems are designed for fault tolerance, observability, and operational excellence. You will perform deep technical reviews, troubleshoot complex issues, and define patterns for resiliency by design. As a hands-on engineer, you will collaborate with development and production support teams, advocate chaos engineering, and build a culture of designing for failure. This position requires strong technical breadth across infrastructure, applications, networks, databases, and integrations, combined with expertise in modern reliability engineering practices.

Job Responsibility:

  • Drive strategies to improve reliability, maintainability, and scalability across payment flows and platform components
  • conduct deep technical assessments of system architectures, identifying risks and recommending improvements for fault tolerance and disaster recovery
  • act as a senior escalation point for production incidents, lead RCA, and implement permanent fixes to prevent recurrence
  • define and enforce reliability patterns, frameworks, and best practices
  • advocate and implement chaos engineering principles to validate system resilience under real-world failure scenarios
  • design and implement full-stack observability solutions, including metrics, logging, distributed tracing, and alerting
  • develop automation for failover, capacity management, and self-healing mechanisms to reduce operational risk
  • partner with development, infrastructure, and production support teams to embed reliability into the SDLC
  • analyze service risk assessments and production incidents to identify systemic issues and drive long-term improvements
  • promote operational excellence and a mindset of designing for failure across all engineering teams
  • provision of guidance and expertise to engineering teams to ensure alignment with best practices and foster a culture of technical excellence
  • contribution to strategic planning by aligning technical decisions with business goals, anticipating future technology trends, and providing insights to optimize product roadmaps
  • design and implementation of complex, scalable, and maintainable software solutions, considering long-term viability and business objectives
  • mentoring and coaching to junior and mid-level engineers to foster professional growth and knowledge sharing, elevating the overall skillset and capabilities of the organization
  • collaboration with business partners, product managers, designers, and other stakeholders to translate business requirements into technical solutions and ensure a cohesive approach to product development
  • innovation within the organization by identifying and incorporating new technologies, methodologies, and industry practices into the engineering process

Requirements:

  • 12+ years in software engineering or infrastructure roles
  • at least 5 years focused on reliability engineering or SRE
  • proven experience building and operating fault-tolerant, highly available systems at scale
  • strong knowledge of distributed systems, resiliency patterns (circuit breakers, retries, failover), and disaster recovery strategies
  • expertise across infrastructure (compute, storage, networking), application architecture, databases, and integration patterns
  • ability to troubleshoot complex technical issues across distributed systems and perform deep root cause analysis
  • skilled at working with development, operations, and architecture teams to embed reliability into design and delivery
