WHY BOX NEEDS YOU

Our Mission: Simplify and accelerate how Boxers bring applications to life. We provide a unified platform for configuring, deploying, and running Box services seamlessly, securely, reliably, and efficiently across optimal regions worldwide.

Our team owns Box’s Platform as a Service (PaaS) based on Kubernetes. With Box being an early adopter, supporter, and contributor of Kubernetes, you will work for the company that introduced kubectl, kube-state-metrics, kube-applier, and kube-exec-controller to the open-source community. Every team and service at Box relies on our platform and we are looking for a leader for this team. This is where you come in! 

We are looking for a Software Engineer to join our Kubernetes Platform Team. In this role, you will design, build, and operate scalable, reliable, and secure Kubernetes-based infrastructure that enables product teams to deploy and run applications efficiently. You will work on core platform services, improve developer experience, and contribute to the long-term evolution of our cloud-native platform. This role requires strong backend engineering skills, deep knowledge of Kubernetes and cloud-native technologies, and the ability to work independently on complex technical problems.

WHAT YOU’LL DO

• Design, develop, and maintain Kubernetes platform components and services (e.g., clusters, operators, controllers, admission webhooks).
• Build and operate scalable, highly available Kubernetes environments in hybrid cloud infrastructure.
• Develop internal platform tools and APIs to improve developer productivity and self-service capabilities.
• Implement best practices for reliability, security, observability, and cost optimization across the Kubernetes platform.
• Collaborate with application and security teams to understand requirements and provide platform solutions.
• Troubleshoot complex production issues related to Kubernetes, networking, storage, and distributed systems.
• Automate infrastructure provisioning and lifecycle management using Infrastructure as Code terraform.
• Contribute to technical design reviews, architecture discussions, and platform roadmaps.
• Mentor early-career engineers and provide technical guidance within the team.
• Stay current with Kubernetes ecosystem trends, CNCF projects, and cloud-native best practices.
