Reporting into:
Systems Architect

We are looking for an experienced, hands-on Dev Ops & Cloud Infrastructure Manager to take ownership of the day-to-day operation, reliability, security, cost efficiency, and continuous improvement of our cloud infrastructure and deployment processes.

Our primary infrastructure is hosted on AWS, with additional AI and Big Data workloads running on Google Cloud Platform (GCP). Our development and deployment workflows are centred around Git Hub, while our Linux-based workloads predominantly run on Ubuntu.

This is a practical, hands-on role. In some areas, you will be recommending and implementing new practices based on your experience and industry best practice, while in others, you will take ownership of existing processes and refine and optimise them.

The successful candidate will be comfortable moving between cloud infrastructure, Linux administration, CI/CD pipelines, monitoring, security, cost optimisation, and production deployments. Ideally, you will have experience in automation and be familiar with AI-augmented workflows.

While the role carries ownership of our Dev Ops and cloud infrastructure function, we are looking for someone who enjoys being close to the technology rather than purely managing from a distance.

Take day-to-day ownership of our AWS environment, ensuring that it remains reliable, secure, performant, and cost-effective.

Responsibilities will include:

• Managing and maintaining AWS infrastructure and services.
• Proactively identifying and implementing AWS cost optimisation opportunities.
• Managing Reserved Instances / Savings Plans and ensuring commitments remain appropriate for current and forecast workloads.
• Improving infrastructure monitoring, dashboards, logging, and alerting.
• Continuously improving our AWS Security Hub posture and addressing identified security findings.
• Reviewing and improving AWS security configurations, IAM permissions, network security, and general cloud security practices.
• Monitoring infrastructure capacity, availability, and performance.
• Supporting incident investigation and root-cause analysis.
• Identifying opportunities to automate repetitive operational tasks.
• Maintaining appropriate backup, recovery, and business continuity processes.
• Keeping infrastructure components and operating systems appropriately patched and up to date.
• Simulating disaster recovery scenarios to ensure our systems are robust.

Git Hub is central to our software development and deployment processes.

The role will:

• Take ownership of our existing CI/CD processes and continuously improve them.
• Maintain and enhance existing Git Hub Actions workflows while creating new workflows where required.
• Work closely with developers to make software deployments reliable, repeatable, and efficient.
• Manage deployments across our various environments, including development, testing/staging, and production.
• Improve deployment controls, release processes, rollback capabilities, and visibility.
• Help troubleshoot build, deployment, and environment-related issues.
• Maintain appropriate management of secrets and credentials used within CI/CD pipelines.
• Promote automation and Infrastructure-as-Code wherever practical.

Our server workloads predominantly run on Ubuntu Linux.

The successful candidate must therefore be highly comfortable working from the Linux command line and will be responsible for:

• Maintaining and administering Ubuntu servers.
• OS patching, upgrades, package management, and general server maintenance.
• Monitoring server health, capacity, disk utilisation, memory, CPU, and system performance.
• Troubleshooting operating system, networking, application, and performance issues.
• Hardening servers and maintaining appropriate security configurations.
• Automating administration and operational activities.

Strong Bash scripting skills are essential. The ability to quickly develop reliable scripts for automation, troubleshooting, deployments, maintenance, and operational tasks will be an important part of the role.

While AWS represents most of our infrastructure, our AI and Big Data platforms are hosted within GCP.

The role will provide operational oversight and support for these environments, including:

• Maintaining GCP infrastructure and services.
• Monitoring availability, performance, security, and costs.
• Supporting AI and Big Data…
