About the Role
Streamline, automate, and optimize Kard’s internal developer platform to make building, deploying, and operating software fast, seamless, and reliable. You will focus on creating scalable infrastructure, improving developer experience, and reducing operational friction, ensuring engineers at Kard can deliver value quickly and with confidence.
This role is not just about building—it’s about making smart choices. You will evaluate build vs. buy trade-offs, leveraging automation, open-source tools, and third-party services to create cost-effective, user-friendly solutions. Your decisions will directly impact developer efficiency, infrastructure scalability, and Kard’s ability to innovate.
Your work will span AWS, Kubernetes, Terraform, CI/CD automation, and developer productivity tooling, keeping Kard’s infrastructure scalable, efficient, and secure. You will collaborate with engineering teams to improve observability, compliance, cost management, incident response, and deployment workflows, eliminating bottlenecks and reducing cognitive load. You will advocate for platform usability and developer ergonomics, ensuring Kard’s internal infrastructure accelerates, rather than hinders, product innovation.
Success in this role means outcomes over output. You will align platform decisions with business needs, ensuring Kard remains lean, efficient, and adaptable. Whether improving our multi-account AWS architecture, streamlining deployments, or enhancing security automation, your work will have a lasting impact on how Kard engineers build and deliver value.
