Sr. Cloud Infrastructure Engineer

Job Description

We are seeking a Senior Cloud Infrastructure Engineer to join our Engineering team. This role is central to building, operating, and scaling the cloud infrastructure that powers our platform, and to making our software easy to deploy both in our cloud-hosted environments and in customer-managed environments.

This engineer will work closely with platform and product engineering to improve the reliability, automation, and operational maturity of our AWS and Kubernetes environments. Some of our environments serve regulated, security-sensitive customers; while deep security specialization is not required, this engineer should be comfortable operating within an established, security-conscious baseline.

The ideal candidate combines strong hands-on infrastructure expertise with a practical, execution-focused mindset and a bias toward automation.

Core Responsibilities

• Design, implement, and maintain scalable, reliable infrastructure in AWS
• Operate and improve Kubernetes-based environments, including production workloads
• Build and maintain infrastructure as code using Terraform
• Improve CI/CD pipelines, deployment workflows, and release automation in partnership with engineering teams
• Build and maintain the packaging and reference architectures customers use to install our software in their own environments
• Strengthen observability across the platform, including monitoring, logging, alerting, and actionable dashboards
• Improve developer experience through tooling, environment automation, and self-service infrastructure
• Operate within and preserve the established security and compliance posture of our environments
• Monitor, troubleshoot, and resolve complex infrastructure issues with clear and timely communication
• Participate in incident response and post-incident analysis
• Develop and maintain documentation, runbooks, and technical standards
• Identify opportunities to improve cost efficiency, performance, and resilience across environments

Required Qualifications

• Minimum of 5 years of experience in DevOps, Infrastructure Engineering, Platform Engineering, or Site Reliability Engineering
• Strong hands-on experience with AWS in production environments
• Proven experience operating Kubernetes in production
• Strong experience with Terraform and infrastructure-as-code practices
• Proven experience building or improving CI/CD pipelines and deployment automation
• Solid understanding of cloud networking, IAM, secrets management, and operational controls
• Experience with monitoring, logging, and observability tooling
• Scripting proficiency in Python, Go, Bash, or similar
• Excellent troubleshooting and problem-solving skills in complex production environments
• Strong communication skills with the ability to explain technical concepts to both technical and non-technical stakeholders
• Must live/work in the U.S.
