Senior Site Reliability Engineer

Senior Site Reliability Engineer Location: Remote About the Role We are seeking a highly specialized and experienced Senior Site Reliability Engineer (SRE) to drive the reliability, performance, and automation of our core platform. This role requires an exceptional blend of deep programming expertise in both Ruby and Go , coupled with hands-on mastery of Linux systems, advanced networking concepts (specifically IPSec), and modern container orchestration. You will be instrumental in bridging development velocity with operational stability, creating self-healing systems, and eliminating toil across the organization. What You Will Do Engineering Reliability: Design, implement, and maintain highly available, scalable, and secure production infrastructure using Infrastructure as Code (IaC) principles. System & Tooling Development: Lead the development of new internal services, automation tools, and critical performance enhancements, leveraging Go for high-performance systems and Ruby for platform-specific tooling and automation. Networking & Security: Configure, manage, and troubleshoot advanced network connectivity, with a focus on IPSec tunnels and complex Linux networking for secure data transfer between environments. Observability: Build and optimize comprehensive monitoring and alerting systems using Prometheus and Grafana to define and meet critical Service Level Objectives (SLOs). Container Management: Own the deployment, lifecycle, and configuration of containerized applications using Helm to standardize releases across Kubernetes clusters. Automation: Drastically reduce operational toil by writing sophisticated scripts in Python and advanced Shell Scripting/PowerShell for operational tasks, CI/CD pipelines, and automated incident response. Incident Response: Serve as a technical escalation point in on-call rotations, leading the effort to conduct root cause analyses (RCAs) and implementing preventative measures to ensure issues never recur. GitOps: Utilize Git workflows for all infrastructure and application configuration changes, promoting a systematic and auditable approach to system management. Required Skills & Experience Deep Technical Expertise (Must Haves) Expert Proficiency in Ruby (5+ years): Demonstrated ability to write, debug, and optimize complex services and high-level automation/frameworks in Ruby. Expert Proficiency in Go (Golang) (3+ years): Proven experience building production-grade infrastructure tools, microservices, or platform components in Go. Networking Security (IPSec): Deep, hands-on experience configuring, troubleshooting, and securing VPNs/site-to-site connectivity using IPSec in a production environment. Container Orchestration: Expertise with Helm for packaging and deploying applications on Kubernetes (K8s). Observability: Extensive experience setting up, administering, and utilizing the Prometheus time-series database and Grafana for data visualization and dashboard creation. Operating Systems: Mastery of the Linux operating system and its internals. Bachelor’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience. Core SRE Skills - Preferred Automation & Scripting: Strong proficiency in Python and robust Shell Scripting (Bash/Zsh) or PowerShell for system automation and administration. Infrastructure as Code & Version Control: Excellent knowledge of Git for source control and significant experience with IaC tools (e.g., Terraform, Ansible) for infrastructure automation. Troubleshooting: Elite-level debugging and performance tuning skills across the entire stack (kernel, network, application, database).
