Who We Are: Architects of the Digital Backbone

At the Rack, we specialize in creating and managing the foundational technology layer that enables digital transformation for businesses worldwide. We are not a consumer-facing brand but the essential partner for companies requiring hyperscale, reliability, and cutting-edge performance. Our expertise is organized around several interconnected pillars:

• Cloud & Hyperscale Infrastructure: Designing and operating massive-scale data center environments, cloud platforms, and distributed computing resources.

• Networking & Connectivity: Building ultra-low-latency, high-throughput global networks, content delivery systems, and interconnection fabrics.

• Hardware Systems Engineering: Developing custom server architectures, storage solutions, and specialized silicon to optimize for performance, power efficiency, and total cost of ownership.

• Infrastructure Software: Creating the orchestration, management, and automation software that brings our global physical infrastructure to life as a cohesive, programmable platform.

• Technical Operations & Support: Ensuring 24/7/365 reliability, security, and performance through world-class site operations, monitoring, and customer support.

We operate on a truly global scale, with points of presence and teams strategically located to serve an international clientele, fostering a culture of technical depth, operational rigor, and relentless innovation.

The Opportunity: Engineer the Unseen Engine

We are recruiting for a spectrum of roles to support rapid growth and the launch of next-generation infrastructure services. This is a call for systems engineers, network architects, software developers, and operations specialists ready to build what’s next. Successful candidates will join highly technical teams with opportunities to impact our global platform. Current focus areas for hiring include:

• Site Reliability Engineering (SRE) & Production Operations: Ensuring the extreme reliability and performance of our global platform through automation, monitoring, and incident response. Building software to manage infrastructure.

• Hardware & Data Center Engineering: Roles in mechanical/electrical design for data centers, hardware systems validation, supply chain logistics, and firmware development for custom hardware.

• Network Engineering: Designing, deploying, and scaling our global backbone, edge networks, and data center fabrics. Deep work with routing protocols, optical transport, and network automation.

• Software Development, Infrastructure: Developing the core control plane software, APIs, and automation tools that provision, manage, and secure our infrastructure resources.

• Customer Solutions Architecture: Working directly with enterprise and developer customers to architect solutions using the Rack’s infrastructure, translating complex requirements into technical reality.
