Pax8 | Hybrid | Farnborough (preference) or Bristol UK

Pax8 is hiring a Senior Infrastructure Engineerin the UK to strengthen our cloud, networking, telephony and infrastructure capability as we scale the technology marketplace of the future.

Build, Automate and Shape What Comes Next

This is a brilliant opportunity to become a senior technical voice in a growing Technology Services team, where your expertise will directly influence how our internal platforms, cloud infrastructure, telephony, automation and workplace technology evolve.

You’ll work on meaningful, business-critical projects — from Pax8 OS, GitHub enablement and telephony architecture through to networking, cloud platforms, infrastructure resilience and automation. As Pax8 continues its AI journey, you’ll join at a point where new starters can grow alongside new technology, using smart automation and AI-enabled ways of working to remove manual effort, improve service quality and help our teams move faster.

Life at Pax8

At Pax8, it’s business, and it IS personal. We’re passionate, creative, unconventional and proudly people-centred. You’ll be joining a company recognised as a Great Place to Work and listed among the UK’s Best Workplaces in Tech 2025. You can also get a feel for our culture, values and journey through Pax8 and our people.

What You’ll Be Doing

As our Senior Infrastructure Engineer, you’ll become a trusted technical escalation point and a key contributor to how we design, improve and support technology across Pax8.

Your day-to-day will include:

Leading complex infrastructure, cloud, networking and telephony work that keeps our systems reliable, secure and scalable

Supporting and improving services across Microsoft Azure, Amazon Web Services, hosted cloud environments, servers and enterprise networking

Helping shape telephony solutions that give Pax8 stronger control, consistency and visibility across call routing, providers, numbers and business tools

Working on Pax8 OS, GitHub adoption and technology projects that connect teams across regions

Driving automation across manual processes using tools such as Terraform, Ansible, Chef, Puppet, PowerShell and AI-enabled approaches

Acting as a senior troubleshooting partner for complex incidents across cloud, infrastructure, telephony, audio, networking and workplace technology

Improving documentation, standards, alerting, reporting and disaster recovery practices so knowledge is shared and services become stronger

Coaching and mentoring Level I, II and III engineers, helping the team grow technical confidence and capability

Partnering with Engineering, Security, Product, Workplace Experience, Vendor and Technology Operations teams to deliver joined-up solutions

The Impact You’ll Make

You’ll help reduce dependency on individual specialists, raise the technical standard across the team and create more scalable, repeatable ways of working.

Your work will improve how Pax8 supports internal teams, partners and business-critical platforms — while helping a newer team establish stronger standards for automation, resilience, documentation and service excellence.

This is a role where you can leave a visible legacy: better systems, clearer knowledge, stronger engineering practices and a more unified technology experience across regions.

What You’ll Bring

You’ll be a great fit for us if you have:

• Extensive experience across cloud platforms, infrastructure, networking, servers and telephony

• Proven diagnostic and troubleshooting ability, especially with complex, multi-system issues

• Considerable knowledge of Microsoft Azure and Amazon Web Services, with Google Cloud Platform experience beneficial

• Strong understanding of physical and virtual networking, routing, hosted cloud environments, monitoring, alerting, traffic analysis, load balancing, backup and recovery

• Demonstrated experience with automation and Infrastructure as Code, using tools such as Terraform, Ansible, Chef, Puppet or PowerShell

• Strong Linux experience, and advanced competency with Terminal/Command Line interfaces

• Proven ability to mentor, coach and support engineers across different technical levels

• Confidence working with stakeholders across Technology, Security, Product, Workplace Experience and external providers

• A clear, thoughtful approach to documentation, knowledge sharing and continuous improvement

• An adaptable working style, with the openness to travel occasionally across UK and wider EMEA offices

• English language skills; additional languages would be beneficial

• ITIL qualifications

• Cisco qualifications

• ISO certification experience

• Advanced Microsoft Azure, Amazon Web Services or Google Cloud Platform certifications
