DevOps Engineer

About the company

Join an innovative space technology organisation working to support the long-term sustainability and development of space activities. The company combines advanced engineering, software and operational excellence to address complex challenges with real-world impact.

You will become part of a collaborative, international environment where technical expertise, continuous improvement and responsible innovation are highly valued. Teams are encouraged to take ownership, share knowledge and develop practical solutions that strengthen both the organisation and its mission.

The company offers the opportunity to work on meaningful infrastructure challenges across cloud, on-premises platforms, automation and emerging AI technologies. Its hybrid working environment supports flexibility while maintaining strong collaboration between technical teams and business stakeholders.

What the job entails

As a Platform Engineer, you will design, build and operate Linux and Ubuntu infrastructure, container environments and internal platform services. You will work across AWS EC2, on-premises Proxmox VE, Docker, GitLab CI/CD and other essential systems.

Your responsibilities will include infrastructure provisioning and configuration using Terraform, Ansible and Git; development of CI/CD and GitOps workflows; and the operation of internal services, development environments and AI/LLM infrastructure. You will also support monitoring, logging, security hardening, patching, backups, performance optimisation and incident response.

You will lead root cause analysis, post-incident reviews and reliability improvements while maintaining runbooks, standard operating procedures and architecture documentation. The role involves close collaboration with other departments, mentoring junior engineers and contributing to infrastructure strategy. Planned weekend or evening maintenance may occasionally be required, with future progression towards a Lead DevOps Engineer position.
