Site Reliability Engineer

Position Overview

We are seeking an experienced Site Reliability Engineer to join our Security team, taking full responsibility for the cloud infrastructure critical to our security framework. This role centers on infrastructure and networking, focusing on designing, securing, and operating a multi-cloud environment spanning AWS, GCP, and Azure. You will manage network security, egress controls, and infrastructure as code, ensuring a robust foundation for our systems.

Your duties include developing and maintaining Terraform and Ansible configurations to define environments, operating production Kubernetes clusters (GKE), and overseeing network components such as Cloudflare, Tailscale, and egress proxy systems that regulate traffic flow.

Your efforts will directly shape our cloud strategies, security protocols, and automation processes, delivering immediate enhancements to risk management and system resilience.

Key Responsibilities

• Design, maintain, and enhance multi-cloud infrastructure reliability and security across AWS, GCP, and Azure.
• Create and manage infrastructure as code using Terraform, Ansible, and Helm to provision and configure cloud environments.
• Lead network security architecture efforts encompassing egress proxy configuration, traffic segmentation, and outbound traffic oversight.
• Administer and develop Cloudflare services including DNS management, WAF, edge security, and traffic routing, along with API gateway layers (Zuplo).
• Operate Tailscale for zero trust network access, implementing access policies and expanding adoption across environments.
• Manage production Kubernetes (GKE) clusters with emphasis on security hardening, network policies, and secure deployment strategies.
• Develop observability dashboards using Grafana to monitor network and infrastructure health, identifying issues proactively.
• Strengthen CI/CD pipelines leveraging GitHub, GitLab, and ArgoCD to bolster infrastructure and supply chain security.
• Participate in on-call rotations, lead incident response for infrastructure and network issues, conduct root cause analyses, and implement lasting fixes.
• Automate repetitive infrastructure tasks to reduce manual effort and improve efficiency.
• Serve as a key liaison connecting security and platform engineering teams on cloud infrastructure and network-related initiatives.

Qualifications and Requirements

• Minimum of five years in Site Reliability Engineering, infrastructure, or platform engineering roles managing production workloads on multiple cloud providers.
• Competency in SRE fundamentals including establishing SLOs, toil measurement, conducting blameless postmortems, and leveraging reliability metrics for engineering decisions.
• Extensive practical experience with AWS, GCP, and Azure networking components such as VPCs, peering, firewalls, and load balancers.
• Proficiency in infrastructure as code tools and configuration management, specifically Terraform and Ansible.
• Strong foundation in network security, with expertise in designing and operating egress controls and proxy infrastructure for compliance purposes.
• Hands-on experience managing Kubernetes in production environments, including Helm usage and GitOps deployment with ArgoCD.
• Knowledge of Cloudflare or equivalent edge/CDN/WAF platforms and API gateway technologies.
• Familiarity with Tailscale or alternative zero trust network access solutions.
• Previous on-call experience, carrying pagers, leading postmortems, and prioritizing comprehensive problem resolution over quick fixes.
• Advanced scripting and automation capabilities using Go or Python for developing tools, runbooks, and automation scripts.
• Effective communication skills for direct collaboration with security, compliance, and engineering stakeholders.

Desirable Skills

• Experience operating Kafka or similar streaming technologies, particularly in log and telemetry pipelines.
• Knowledge of SOC 2 compliance processes and experience with tools like Vanta or other governance, risk, and compliance (GRC) platforms.
• Background in industries with strict regulations such as fintech or cryptocurrency where continuous audit readiness and network controls are paramount.
• Exposure to Temporal or comparable workflow orchestration tools aimed at reliable automation.
• Experience with secrets management systems such as HashiCorp Vault within a multi-cloud setting.

Compensation

Salary range for this position is $180,000 to $271,000 annually. Compensation varies based on role level, skills, experience, and geographic location.
