Senior Site Reliability Engineer I

About This Opportunity

We are representing a confidential client in the customer engagement technology sector, seeking a Senior Site Reliability Engineer to join their Canadian operations. This is a critical infrastructure role focused on maintaining and scaling the ingress layers that serve as the primary entry point for massive API traffic volumes.

Our client operates distributed systems at extraordinary scale, and this position will be embedded with product engineering teams to ensure their Ruby on Rails and Go-based API services remain highly available and resilient under extreme load conditions.

Responsibilities

• Lead NGINX & Kubernetes Ingress Infrastructure: Architect, configure, and operate high-performance NGINX routing, proxying, and ingress controller layers managing real-time API ingestion traffic at scale
• Own Scaling Operations: Design, expand, and tune automated scaling routines for high-throughput API services using RED metrics, Horizontal Pod Autoscalers, and custom scaling policies to handle traffic spikes seamlessly
• Partner with Product Teams: Translate product requirements into resilient, highly available technology stacks, working directly with engineering teams owning API features
• Establish SLIs and SLOs: Define meaningful Service Level Indicators and Objectives for API services, helping teams balance rapid feature deployment with stability through error budget management
• Systems Design & Capacity Planning: Conduct bottleneck profiling and capacity planning to ensure enterprise-grade SLA compliance
• Incident Response: Participate in PagerDuty on-call rotation, lead root-cause analysis and blameless retrospectives, and translate operational learnings into permanent system improvements
• Proactive Prevention: Update runbooks and implement preventive measures to reduce recurring incidents

What We're Looking For

Required Experience & Skills:

• 5+ years of experience as a Site Reliability Engineer or DevOps Engineer in high-scale production environments
• Deep hands-on expertise configuring, troubleshooting, and operating NGINX proxying, routing, and ingress controllers under heavy traffic loads
• In-depth proficiency with Kubernetes administration, including cluster networking, container orchestration, scheduling, and deployment
• Excellent understanding of Linux/Unix internals: disk I/O, memory allocation, TCP/IP networking, and process management
• Strong programming/scripting skills in Ruby and/or Go preferred (Python or Java also valued) for building automation tools and platform frameworks
• Experience managing infrastructure using IaC technologies such as Terraform, Ansible, or Chef
• Strong systems thinking: understanding interfaces, boundaries, failure modes, and cascading effects in distributed architectures
• Excellent documentation practices and comfort collaborating asynchronously across remote-first, global teams

Preferred Skills:

• Familiarity with data-tier technologies including Redis, Kafka, Postgres, or MongoDB
• Experience with observability platforms such as Prometheus, Grafana, or Datadog
• Practical experience deploying infrastructure in major cloud environments (AWS, GCP, Azure)
