Jobs at Jagex: The RuneScape Company (Now Hiring) — 15 open

Office location: Cambridge, UK – This position can accommodate flexible working options. Candidates must be based (or be willing to relocate) within a comfortable commuting distance of our Cambridge office to attend onsite as required.

Are you looking to start a career in cloud and reliability engineering, working on the infrastructure behind some of the world's biggest and longest-running online games?

As a Junior Cloud Reliability Engineer in our Developer Platform team, you'll help support the backend infrastructure powering RuneScape, Old School RuneScape, and RuneScape: Dragonwilds. Working within a small team, you'll gain hands-on experience across cloud infrastructure, networking, Linux systems, and game services while learning how to keep hundreds of thousands of players online every day.

This role offers a lot of development opportunities. You'll begin by supporting existing systems and responding to day-to-day operational requests before progressing to independent ownership of infrastructure projects as your technical skills and experience grow.

What you’ll be doing:

• Learn our backend infrastructure which will cover game world systems, networking, build pipelines, version control, data center hardware, and cloud infrastructure.
• Handle day-to-day support requests and troubleshoot issues across our live systems, escalating quickly when needed and following up to understand the root cause.
• Support development teams in managing cloud-native workloads and consuming our cloud platform through Infrastructure-as-Code.
• Contribute to the management of our Linux virtual machine fleet, including monitoring, configuration management, and workload optimisation.
• Participate in incident response and post-mortems, developing your understanding of how complex systems fail and how to make them more resilient.

What we’re looking for:

• Comfortable working in a Linux terminal environment and writing bash scripts.
• Familiarity with at least one programming language such as Python - we’re open to any language if you can demonstrate how you think through problems.
• A solid understanding of networking concepts and the OSI model.
• A genuine problem-solving mindset - you enjoy working through complex issues, aren’t satisfied with surface-level answers, and naturally ask how and why things work the way they do.
• Good communication skills and a desire to keep learning, including the confidence to ask questions and challenge existing approaches.
• Prior infrastructure or SRE experience is a plus.

What we offer:

When you join Jagex you can look forward to a generous Perks & Benefits package including:

• 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!
