Job description

Location: Cambridge, UK - This position offers flexible working options, including predominantly remote work. Applicants should be based (or willing to relocate) within a comfortable commuting distance of our office to attend onsite as required.

About the role

Are you a cloud platform engineer who is ready to take real ownership of the cloud infrastructure behind some of the world's most-played games? As a Senior Cloud Platform Engineer in our Cloud Platform team, you'll help maintain and evolve the hybrid infrastructure underpinning RuneScape, Old School RuneScape, and DragonWilds. We're in the middle of a significant transformation - moving more and more of our infrastructure into the cloud - and we need someone who can lead in the AWS space, drive that programme forward, and mentor the team as we go. This is hands-on, production-critical work across a wide remit: data centres, Linux, networking, cloud and everything in between. You'll work alongside the Principal Cloud Tech Engineer, contribute to architectural decisions, and take real ownership of projects - not just support them.

What you'll be doing

• Lead and actively contribute to our cloud migration programme - including lift-and-shift into AWS - making architectural decisions and driving the project forward with the team.
• Work with the Principal Cloud Tech Engineer and Cloud Platform team to design and implement infrastructure to in-house standards and industry best practices.
• Apply IaC principles across legacy internal systems and new cloud deployments, reducing technical debt and improving platform reliability over time.
• Provide critical support for our operational systems - game servers, web servers, and backend infrastructure - ensuring stability across live production environments.
• Mentor junior and mid-level engineers, sharing knowledge and helping the team grow their cloud capability.
• Participate in an on-call rota (currently 1 week in 5, Monday to Monday) to support production systems when issues arise.

What we're looking for

• Strong, demonstrable experience with Linux and AWS - including IAM, EKS, ECS, CloudWAN, and Direct Connect/SiteLink - and the confidence to lead projects in the AWS space.
• Proven experience applying IaC principles, with deployed projects to show for it.
• Solid understanding of networking and familiarity with technologies such as VyOS, Palo Alto, and Arista.
• Experience with CI/CD pipelines and a DevOps mindset - understanding how to build and maintain reliable delivery infrastructure.
• Experience with on-premise environments and how they interconnect with cloud infrastructure in a hybrid setup; familiarity with configuration management tooling (preferably Puppet) is a plus.
• Kubernetes experience is a strong advantage, as is experience in gaming, VFX, or other creative technical environments.
• Above all, we're looking for someone who is genuinely curious and open to learning across a wide and evolving remit.

What we offer

• Private Healthcare, including Dental Plan.
• Discretionary annual performance bonus.
• Minimum 6% Pension contributions.
• Life Insurance.
• Enhanced family leave policies from day 1.
• Flexible working hours.
• 25 days annual leave + Bank holidays & the option to buy/sell holidays + so much more!
