Take ownership of the cloud and compute infrastructure supporting an ambitious technology platform as a Senior CloudStack Engineer.

Company Overview
This London-based technology business is developing infrastructure and technology at the intersection of artificial intelligence, data and high-performance computing.

Its technical environment spans cloud platforms, physical infrastructure and compute systems, creating an opportunity to work across the complete infrastructure stack.

As the platform continues to develop, the business is looking for experienced infrastructure engineers who can solve complex technical challenges and contribute to the reliability, performance and scalability of its cloud environment.

Job Overview
As a Senior CloudStack Engineer, you will take significant responsibility for deploying, managing, troubleshooting and improving cloud and compute infrastructure.

The Senior CloudStack Engineer position is aimed at someone with around 3 to 6 years of experience across cloud infrastructure, Linux, networking, virtualisation or platform engineering.

You will work across Apache CloudStack or similar private cloud technologies, Linux, KVM, networking, storage and compute infrastructure.

Strong CloudStack experience would be particularly valuable, although experienced engineers coming from OpenStack or comparable private cloud environments are also encouraged to apply.

As a Senior CloudStack Engineer, you will be expected to operate with greater independence, taking ownership of complex technical problems and contributing to decisions around infrastructure architecture, reliability, automation, performance and scalability.

Here's what you'll be doing:

• Deploying, configuring and managing Apache CloudStack infrastructure
• Taking ownership of cloud infrastructure reliability, availability and performance
• Managing compute, virtual machines, storage and networking across the environment
• Managing and troubleshooting Linux and KVM virtualisation environments
• Diagnosing complex issues across CloudStack, networking, storage, compute and physical infrastructure
• Supporting the deployment and expansion of data centre and compute capacity
• Investigating infrastructure incidents, identifying root causes and implementing long-term solutions
• Supporting infrastructure upgrades, migrations and configuration changes
• Improving infrastructure monitoring, resilience and operational processes
• Developing or improving automation for repetitive infrastructure tasks
• Contributing to infrastructure architecture and scalability decisions
• Creating and maintaining clear technical documentation
• Supporting less experienced engineers and sharing technical knowledge
• Working closely with senior technology leadership on infrastructure priorities

• Around 3 to 6 years of experience within cloud infrastructure, systems, platform engineering or a related technical environment
• Strong experience with Apache CloudStack, OpenStack or comparable private cloud technologies
• Strong Linux administration and troubleshooting skills
• Good knowledge of KVM or similar hypervisor technologies
• Strong understanding of compute, storage, virtualisation and cloud infrastructure
• Good understanding of TCP/IP, DNS, VLANs and wider networking principles
• Experience supporting production or business-critical infrastructure
• Ability to diagnose complex infrastructure problems and take ownership through to resolution
• Experience with infrastructure automation, scripting or Infrastructure as Code would be advantageous
• Understanding of infrastructure monitoring, resilience, reliability and performance
• Strong analytical and technical problem-solving skills
• Ability to communicate complex technical issues clearly
• Experience supporting or mentoring less experienced engineers would be beneficial
• An interest in AI infrastructure, data centres and high-performance computing

• £70,000 to £90,000 salary depending on experience
• Significant ownership of live cloud and compute infrastructure
• Exposure to infrastructure supporting AI and data-intensive technology
• Opportunity to develop deeper specialist Apache CloudStack expertise
• Hands-on exposure across Linux, KVM, networking, storage, compute and physical infrastructure
• Direct collaboration with experienced technology leadership
• Opportunity to influence how infrastructure develops and scales
• Scope to progress towards cloud architecture, senior platform engineering and technical leadership
• Fast-moving technical environment where your work can directly influence the wider platform
