Position Overview

Our client's Events platform powers event marketing, ticket sales, ticket management, and on-site ticket distribution and scanning for organizers running live events. It's a high-throughput, event-driven application on AWS, and it needs a Senior SRE to keep it reliable, well-instrumented, and continuously improving in place.

You will operate and strengthen the platform's AWS infrastructure, CI/CD, and observability, working closely with the engineers who build and evolve the application so the system holds up under real event-day load — on-sales, high-traffic scans, and everything in between.

Key Responsibilities

• Operate and maintain the Events platform's AWS infrastructure — compute, data stores, CDN, and the event bus connecting bookings, tickets, users, and scanning
• Build and extend observability — dashboards, tracing, and alerting that catches problems before customers do, especially around live on-sales and event days
• Maintain and improve CI/CD pipelines for the booking, box office, and ticket-scanning applications, working toward deployments that are repeatable, auditable, and low-risk
• Partner with the engineers building and evolving the Events platform, understanding the event-driven architecture well enough to contribute code, diagnose production issues, and suggest infrastructure improvements
• Participate in on-call and incident response for the platform, with particular attention to the operational patterns unique to ticket scanning at scale
• Apply IaC discipline to infrastructure changes, avoiding manual, untracked changes to production
• Use AI-assisted development tools (Claude Code or comparable) as part of your workflow to navigate and document a complex codebase and infrastructure estate

Required Qualifications

• ~6 years of experience as an SRE, DevOps engineer, or backend/infrastructure engineer supporting production systems
• Strong, hands-on AWS experience — comfortable operating services like ECS, Lambda, Aurora/RDS, CloudFront, and IAM in a real production environment
• Solid understanding of event-driven architecture — message/event buses (EventBridge, SQS/SNS, Kafka, or comparable), asynchronous workflows, and the failure modes specific to distributed, event-driven systems
• Proficient as a software engineer, not just an operator — comfortable reading and writing code (Node.js, TypeScript, Python, C#/.NET, or similar) to fix issues, write tooling, and contribute directly to the applications you support
• Experience with CI/CD pipelines and deployment automation
• Working knowledge of observability practices — monitoring, alerting, and using tracing/logging tools (CloudWatch, X-Ray, Datadog, or similar) to diagnose production issues
• Familiarity with Infrastructure-as-Code (CloudFormation, CDK, Terraform, or comparable)
• Comfortable using AI-assisted development tools such as Claude Code, Codex, or similar to navigate and understand large codebases

Preferred Qualifications

• Experience with ticketing, event-management, booking, or e-commerce platforms, especially systems with sharp demand spikes (on-sales, high-traffic events)
• Exposure to Azure DevOps
• Familiarity with high-throughput, queue-driven architectures and autoscaling patterns (SQS, KEDA, or similar)
• Experience with mobile or field-device systems that must operate reliably online and offline (e.g., ticket scanning, POS, field service apps)
• Exposure to Angular, React Native, or .NET applications, even if your primary focus is infrastructure
• Background in EdTech, SaaS, or other domains where system reliability has direct, real-time consequences for end users
