Job description

Mount Thor is hiring a software engineer to build the customer-facing control plane and managed services for our compute platform.

Who We Are

Mount Thor makes Apple hardware (macOS and Apple Silicon) available and performant at datacenter scale for AI workloads. We take consumer hardware and build the infrastructure platform around it to enable consumption as elastic compute exposed through developer-friendly interfaces. Our customers use us to develop computer-use model capabilities, deploy long-running agents, and accelerate agentic engineering.

The Team

The Platform team owns Mount Thor’s customer-facing control plane and managed services. It builds the APIs and software customers use to create, configure, and operate compute environments.

The team owns service lifecycle, workload orchestration, tenancy, and integrations with fleet, networking, storage, identity, and security. Its scope includes managed Kubernetes and other services for deploying AI workloads.

• Participate in on-call and own the systems you build in production.

You might thrive in this role if you have

• Built customer-facing infrastructure products or managed cloud services.

• Experience building distributed systems, control planes, operators, or controllers.

• Deep knowledge of Kubernetes internals and cluster lifecycle management.

• Strong programming skills in Go, Python, Rust, or a similar language.

• Strong knowledge of Linux, containers, networking, storage, and security.

• Experience building reliable multi-tenant services and public APIs.

• Led complex infrastructure work from design through production.

• Experience using coding agents to build production software.

Bonus Skills

• Built a managed Kubernetes, Slurm, inference, database, or container service.

• Built Kubernetes schedulers, operators, admission controllers, CNI plugins, or CSI plugins.

• Worked on bare-metal, HPC, or AI compute infrastructure.

• Built private networking, workload isolation, or enterprise identity features.

• Operated macOS or Apple Silicon infrastructure at scale.

• Built infrastructure that software agents can operate safely.
