Staff Systems Engineer - IT & Infrastructure (d/f/m)

This is an interim position on a freelance basis.

Your responsibilities:

• Maintain and operate enterprise cloud infrastructure that serves employees and internal systems, ensuring high availability, performance, and security at all times.
• Lead and evolve identity management across the enterprise — including platform management and Okta — developing concepts and processes to govern both human and agentic identities in a scalable, secure way.
• Support the integration of new tools and systems based on business requirements, owning the technical evaluation, onboarding, and configuration end to end.
• Ensure enterprise systems remain up to date, with security configurations, patches, and compliance standards consistently applied across the board.
• Maintain security backups and redundancies for enterprise infrastructure, proactively identifying and closing gaps before they become incidents.
• Manage and improve network, device management, and systems, keeping the environment stable, modern, and fit for a growing, hybrid workforce.
• Develop automations, AI-powered and agentic solutions, and scripts that reduce manual toil and improve the efficiency of infrastructure maintenance.
• Provide third-level support for cloud applications, acting as the deepest technical escalation point for complex issues and enablement of internal app deployment.
• Collaborate with SRE and platform engineering to assess risk, develop guardrails, and resolve incidents together with application owners.
• Collaborate with the Director of IT to continuously improve the enterprise architecture and infrastructure landscape, contributing strategic thinking alongside hands-on execution.
• Own performance tuning of application stacks, including communication and messaging between applications, load management, and components such as Apache and Ruby.

Your profile

• You bring strong, hands-on experience in enterprise cloud administration — ideally with GCP — and know how to design, operate, and scale cloud environments that real businesses depend on.
• You have solid practical experience with Kubernetes, containerisation, and virtualisation technologies such as Docker and VMware, and you're comfortable navigating complex, layered infrastructure.
• Your networking knowledge is deep and grounded — TCP/IP and related protocols are second nature to you, and you can diagnose and resolve network issues with confidence.
• You implement best practices for network security and governance, ensuring that access, segmentation, and policy controls are consistently applied and continuously improved.
• You're proficient in at least one scripting or programming language such as Python or shell, and you use code as a tool to make infrastructure smarter and more maintainable.
• You have hands-on experience configuring and troubleshooting Google Workspace and Linux environments, and you know how to keep them healthy and secure.
• You've set up and improved monitoring and visualisation systems, and you understand how good observability translates into faster incident response and better decision-making.
• A background in engineering or computer science is a plus — what matters most is that you bring structured thinking and hands-on experience to make systems work together.
