Sr. Cloud Infrastructure Engineer

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.

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

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

Preferred Qualifications

Experience operating stateful workloads on Kubernetes, such as databases or message queues, including persistent storage and backup/recovery

Experience with GitOps-based deployment workflows

Experience packaging software for customer-managed or self-hosted deployment (e.g., Helm charts)

Familiarity with compliance or security frameworks such as FedRAMP, NIST, SOC 2, or similar

Experience with PostgreSQL, cloud storage platforms, and production networking patterns

Experience with configuration management tools such as Ansible

Experience with additional cloud platforms such as Azure or GCP

Experience with service mesh or advanced Kubernetes networking

Experience supporting customer-facing or mission-critical production infrastructure
