About The Position

Nscale is hiring a Senior Infrastructure Engineer specializing in OpenStack Ironic to design, operate, and continuously improve the bare metal provisioning platforms that underpin its infrastructure. The role is part of the Infrastructure Engineering team, responsible for the infrastructure stack supporting internal and customer-facing services. It works closely with network, compute, data centre, support, and pre-sales teams, and serves as a specialist escalation point for advanced provisioning and hardware issues.

The position focuses on OpenStack Ironic, automated hardware lifecycle management, and reliable operation of large-scale physical infrastructure. The engineer will also connect Nscale with the upstream OpenStack community so the bare metal platforms evolve in response to operational needs and industry direction.

Requirements

• Strong experience operating Linux systems and troubleshooting production infrastructure.
• Strong specialist knowledge of OpenStack Ironic and the surrounding provisioning ecosystem.
• Strong understanding of bare metal provisioning, including PXE/iPXE, DHCP, TFTP/HTTP boot, BMC technologies, RAID configuration, firmware management, disk imaging, and node lifecycle states.
• Strong experience with out-of-band management technologies such as Redfish, IPMI, or vendor management interfaces.
• Strong experience designing and building automation for physical and virtual infrastructure using tools such as Ansible.
• Strong scripting skills in Python and Bash.
• Experience troubleshooting complex provisioning and hardware integration issues across server, network, and management layers.
• Experience operating infrastructure at scale, with a focus on reliability, repeatability, and operational safety.
• Ability to collaborate across infrastructure, support, and architecture teams to solve complex technical problems.

Nice To Haves

• Experience contributing to or working closely with upstream open-source communities, particularly OpenStack, Ironic, Metal3, or related infrastructure projects.

Responsibilities

• Design scalable and resilient bare metal provisioning platforms, with a strong focus on OpenStack Ironic.
• Own the physical infrastructure lifecycle, including discovery, enrolment, provisioning, cleaning, deprovisioning, and hardware state management.
• Build and maintain provisioning workflows for a range of hardware profiles, including GPU-enabled and high-performance server platforms.
• Support platform upgrades, lifecycle management, and operational improvements across Ironic and its dependencies.
• Manage and improve integrations between Ironic and OpenStack services such as Nova, Neutron, Glance, Keystone, and Placement.
• Automate hardware onboarding, firmware and BIOS configuration, deployment workflows, validation, and recovery.
• Implement infrastructure automation using infrastructure-as-code and configuration management approaches.
• Ensure provisioning platforms and operational processes align with security, compliance, and operational standards.
• Troubleshoot issues across provisioning pipelines, PXE/iPXE, BMC interfaces, out-of-band management, image deployment, network boot, and hardware compatibility.
• Act as a 3rd/4th line escalation point for advanced bare metal and provisioning incidents.
• Perform root cause analysis and implement long-term fixes to improve reliability and repeatability.
• Participate in on-call rotations and incident response for critical infrastructure services.
• Collaborate with network, compute, data centre, and support teams to deliver reliable physical infrastructure services.
• Contribute specialist input to infrastructure roadmap planning, capacity expansion, standard builds, and hardware platform qualification.
• Support pre-sales and solution design with expert guidance on bare metal capabilities, operational models, and deployment constraints.
• Contribute to upstream OpenStack bare metal communities through bug reports, testing, reviews, design discussions, and code contributions where appropriate.
• Track upstream roadmaps and release changes to inform Nscale’s bare metal strategy, upgrade planning, and platform standards.

Benefits

• Highly competitive US compensation package comprising base pay, bonus, and equity; performance reviews every 12 months.
