[Hiring] Software Developer IV @Rackspace Technology

Role Description

The Private Cloud Product Software Engineering organization is seeking a seasoned Software Developer IV to join our Infrastructure Automation team. In this role, you will be a senior individual contributor and technical leader responsible for building and evolving the platform that programmatically deploys and manages hardware across Rackspace data centers.

You will design and implement Kubernetes Operators and internal developer tooling that bridges our physical infrastructure with cloud-native automation workflows. This is a high-impact, deeply technical role suited for an engineer who is equally comfortable shaping architecture and writing production Go code.

Responsibilities

• Architect and implement Kubernetes Operators and controllers that drive programmatic hardware provisioning and lifecycle management.
• Design and build internal developer tooling and automation pipelines that improve engineering velocity across the organization.
• Own technical decision-making for your domain, including technology selection, API design, and data modeling.
• Write robust, well-tested Go services and tools, maintaining high standards for code quality and operational reliability.
• Collaborate with data and infrastructure teams to model, integrate, and expose hardware inventory and state data (e.g., via DCIM/IPAM systems).
• Identify gaps in existing tooling and automation; propose and lead initiatives to address them.
• Provide technical leadership and mentorship to developers across the team.
• Contribute to operational responsibilities including incident response, observability, and continuous improvement of platform reliability.
• Evaluate new technologies and patterns relevant to infrastructure automation and make well-reasoned adoption recommendations.

Qualifications

• Ten or more years of software development experience, with at least five years writing production Go (Golang).
• Demonstrable experience building Kubernetes Operators or controllers using controller-runtime or kubebuilder.
• Strong working knowledge of the Kubernetes API machinery, including custom resources, admission webhooks, and reconciliation patterns.
• Five or more years working in Linux/Unix environments, including shell scripting and systems-level debugging.
• Experience designing and operating microservices in a Kubernetes-native environment.

Technical Skills

• Deep proficiency in Go, including idiomatic concurrency patterns, testing, and performance optimization.
• Solid understanding of data modeling and APIs for representing infrastructure state — hardware inventory, network topology, provisioning workflows.
• Experience with CI/CD pipelines and GitOps-style workflows (GitHub Actions, ArgoCD, or similar).
• Familiarity with infrastructure-as-code and configuration management tooling.
• Strong debugging, observability, and incident analysis skills.

Soft Skills

• Ability to drive technical architecture from ambiguous requirements through to delivered, production-grade outcomes.
• Excellent written and verbal communication skills; comfortable presenting technical proposals to engineers and stakeholders alike.
• Effective in a globally distributed engineering organization.
• Strong sense of ownership: you treat the systems you build as production responsibilities, not just code deliverables.

Highly Desirable Skills

• Experience with OpenStack services, particularly Nova, Ironic, Neutron, or Keystone.
• Familiarity with DCIM or IPAM tooling such as NetBox or Nautobot, including API-driven automation against these systems.
• Exposure to bare metal provisioning workflows, BMC interfaces (Redfish/IPMI), or hardware lifecycle automation.
• Experience with Ceph, Rook, or other cloud-native storage systems.
• Contributions to open source infrastructure or cloud-native projects.
• Experience with container runtime internals or low-level Linux networking.
