Are you a recent Computer Science or Engineering graduate – or someone with technical know-how and a passion for automation, systems, and infrastructure?

Join the mthree Alumni Graduate Programme, designed to give you everything you need to start strong. From expert-led training to an impactful 12-month placement with a world-leading investment bank, this is your launchpad into the world of Site Reliability Engineering and DevOps.

What You’ll Do

• Support critical infrastructure and deployment pipelines for enterprise-grade systems.
• Learn and apply best practices in system reliability, observability, and automation.
• Work with CI/CD tools, containerisation technologies like Docker, and orchestration platforms like Kubernetes.
• Monitor system performance, identify bottlenecks, and help ensure uptime and reliability.
• Troubleshoot incidents in production environments and implement long-term fixes.
• Collaborate with development, QA, and infrastructure teams to improve system resilience and performance.

What We’re Looking For

• A Bachelor’s degree in Computer Science, Engineering, or a related field (Grade 7/10 or above).

• Familiarity with scripting languages such as Python, Bash, or PowerShell.
• An interest in automation, system monitoring, and CI/CD best practices.
• Fluent English communication skills (written and spoken).
• Completed Greek military service, if applicable.

(Due to the nature of our client commitments in Greece — including long-term placements and time-sensitive onboarding — we require all candidates who are subject to mandatory national service to have either completed or been formally exempted from it prior to joining.)

• Applicants must have the permanent legal right to live and work in Greece at the time of application and on an ongoing basis. Unfortunately, we are unable to provide visa sponsorship now or in the future.
