About the role:

We are seeking a Senior Infrastructure Engineer to take a lead role in designing, securing, and scaling the infrastructure that powers our engineering teams and customer-facing applications. This role is ideal for a hands-on engineer with deep experience in AWS and GCP, a strong security mindset, and a passion for building tools and systems that make developers more productive and operations more resilient.

You will be responsible for driving key initiatives around CI/CD, cloud infrastructure, security hardening, and developer tooling. In addition to technical depth, the ideal candidate brings operational maturity—able to manage vendor relationships, oversee hardware procurement, and help troubleshoot complex network or endpoint issues. If you enjoy working across the stack—from infrastructure to internal tools—and want to have a broad impact on engineering velocity and system reliability, this is the role for you.

What you'll do:

• Design, manage, and scale infrastructure across AWS and GCP, with deep familiarity in both platforms.

• Own and optimize our CI/CD pipelines, dev environment tooling, and release automation processes.

• Implement and manage cloud-native security services like AWS WAF, Security Hub, and ensure best practices are followed.

• Review, prioritize, and patch security vulnerabilities across infrastructure and applications.

• Build internal tools to help developers access logs, debug issues, and operate confidently in production environments.

• Manage vendor relationships for hardware procurement, pricing negotiation, and network troubleshooting.

• Lead MDM setup, device imaging, and work cross-functionally for endpoint and access management.

• Maintain and harden systems running on Ubuntu, including patching, automation, and monitoring.

• Use Infrastructure as Code (IaC) tools (e.g., Terraform) to manage and provision infrastructure consistently.

• Set up and maintain observability stacks (monitoring, logging, alerting) to ensure system reliability and transparency.

• Support incident response, on-call rotations, and improve operational resilience through root cause analysis and automation.

• Collaborate with engineering teams to embed DevOps best practices throughout the development lifecycle.

What you'll bring:

• Cloud expertise in AWS and GCP — comfortable designing, scaling, and securing systems in both.

• CI/CD experience — building reliable pipelines, automating releases, and improving developer workflows.

• Infrastructure as Code — using Terraform and scripting to manage and automate cloud infrastructure.

• Linux & security skills — managing Ubuntu systems, applying patches, and handling security tools and practices.

• Monitoring know-how — setting up alerts, logs, and dashboards to keep systems healthy and reliable.

• Tooling mindset — building internal tools that help developers ship faster and debug more easily.

• IT and incident support — helping with device setup, access management, and on-call incident response.
