Site Reliability Engineer (SRE) - Platform Infrastructure team (100% Remote - Ireland)

About The Job

Hopper is looking for a Senior Site Reliability Engineer to join our Platform Infrastructure team — the group that builds and operates the cloud foundation powering products used by millions of travelers worldwide.

Our mission is to empower engineers across Hopper to ship fast, stay resilient, and scale effortlessly. If you care about automation, scalability, and developer experience — and want to make a tangible impact on a growing travel tech company — this could be the perfect role for you.

You'll help evolve a large-scale, multi-region infrastructure running in Google Cloud, supporting hundreds of engineers and dozens of product teams. You'll contribute to building automated, self-service platform tools, ensuring the foundation is secure, reliable, cost-efficient, and easy to use.

This Role Might Be a Great Fit If You

• Thrive on automating repetitive work and turning best practices into platform-level solutions.
• Take pride in enabling product teams by providing intuitive tools and interfaces for infrastructure and deployment.
• Have a strong bias for practical, reliable solutions over complexity and over-engineering.
• Care deeply about operational excellence: scalable systems, high availability, performance, and cost optimization.
• See developer experience as a product, and continuously look for ways to improve it.
  
  

What Would Your Day-to-day Look Like

• Improve and evolve platform tooling to support a growing number of services and teams across Hopper.
• Design infrastructure workflows that are simple, consistent, and scalable — enabling engineers to build and deploy with confidence.
• Drive automation across key infrastructure components, reducing manual work and increasing reliability.
• Adapt and scale infrastructure offerings to meet the needs of product teams while maintaining a cohesive and maintainable platform.
• Participate in incident response for platform-level issues as part of a globally distributed, sustainable on-call rotation (with team coverage across the Americas and Europe).
• Support engineering teams by troubleshooting platform issues, answering infrastructure-related questions, and reviewing pull requests that affect core systems.
• Collaborate with a small, high-impact team of SREs, focused on operational excellence, performance, and developer experience.
  
  

An ideal candidate has:

• Professional experience in SRE, DevOps, Software Engineering, or Systems Engineering, with a passion for building reliable, scalable infrastructure.
• Strong troubleshooting and incident response skills across distributed systems and cloud-native environments.
• Solid system design and analytical thinking, with a focus on simplicity, performance, and maintainability.
• Clear and effective communication skills, with the ability to collaborate across engineering teams.
  
  

Cloud & Infrastructure Expertise

• Hands-on experience with major cloud platforms — ideally Google Cloud Platform (GCP).
• Deep familiarity with Infrastructure as Code, preferably using Terraform.
• Experience building and operating with containers and Kubernetes, and tools like Helm or Kustomize.
• Working knowledge of Service Mesh technologies, preferably Istio.
  
  

Networking & Security

• Solid understanding of networking fundamentals — DNS, TLS, certificates, ingress controllers, etc.
• Knowledge of cloud and infrastructure security best practices, including IAM, RBAC, and network segmentation.
• Familiarity with authentication and authorization protocols and technologies.
  
  

Observability & Tooling

• Experience with observability stacks — logs, metrics, tracing, and APM (preferably using Datadog).
• Practical knowledge of CI/CD pipelines and deployment automation.
• Exposure to database technologies, both SQL and NoSQL.
  
  

Scripting & Automation

• Comfortable writing scripts in Bash, Python, or similar scripting languages to automate routine tasks and build tooling.
  
  

Perks And Benefits Of Working With Us

• Please ask us about our very generous parental leave, much above industry standards!.
• Unlimited PTO.
• Flexdesk Access Pass AND Work-from-home stipend.

Almost 30% of our app customers purchase at least one fintech product when making a booking; and consumers are 1.6x more likely to repurchase if they add fintech to their booking vs if they booked just travel.

Given the success of its fintech products, Hopper launched a B2B initiative, HTS (Hopper Technology Solutions), which represents more than 50% of the business.

Through HTS, any travel provider (airlines, hotels, banks, travel agencies, etc.) can integrate and seamlessly distribute Hopper’s fintech or travel inventory on their direct channels.
