About the Role

The Senior Cloud Native Platform Engineer plays a key role in building and evolving Nscale’s Kubernetes-native control plane that manages GPU-backed infrastructure for AI workloads at scale.

This is a deeply technical, hands-on role focused on extending Kubernetes through custom APIs and controllers, rather than configuring off-the-shelf components. You will work on production-grade control plane software that encodes infrastructure, scheduling, and policy into Kubernetes-native abstractions, and exposes APIs for both internal and external consumers.

The role sits between mid-level and principal engineers, combining strong individual technical delivery with growing architectural ownership and influence.

What You'll be Doing (Responsibilities)

• Design and implement Kubernetes-native APIs using Custom Resource Definitions (CRDs) that model real infrastructure and platform concepts.
  
  


• Build and operate custom controllers that reconcile desired state safely and reliably in production environments.
  
  


• Work deeply within the Kubernetes control loop, including:

1. Informers, caches, and leader election


2. Ownership, finalizers, and garbage collection


3. Failure handling, retries, and idempotency
   
   

• Write Go as your primary development language, producing maintainable, testable, and production-ready code.
  
  


• Debug complex issues that span multiple layers, including:

1. Kubernetes control plane behaviour


2. Linux kernel, cgroups, and device access


3. Networking, scheduling, and resource isolation

• Integrate with external infrastructure management systems and APIs.
  
  


• Build systems that are observable, supportable, and safe to operate at scale.

• Contribute to design discussions, code reviews, and technical standards within the platform engineering team.
  
  


• Act as a technical mentor to mid-level engineers, supporting skill development and best practices.

About You (Skills / Qualifications)

• Strong, hands-on experience extending Kubernetes through custom controllers and CRDs in production environments.
  
  


• Proven experience writing production-grade Go for backend or control plane systems.
  
  


• Solid Linux fundamentals, including processes, memory management, filesystems, and cgroups.
  
  


• Good understanding of networking fundamentals, including TCP/IP, DNS, routing, and overlay networks.
  
  


• Experience building, operating, or debugging distributed systems in production.
  
  


• Comfortable working across system boundaries and reasoning about failure modes and operational behaviour.
  
  


• Able to collaborate effectively across teams and influence technical outcomes through clear communication and quality engineering.
