Harold Mertzweiller

I am a security engineer with a strong foundation in embedded systems, Linux, and cloud infrastructure. I currently work at Google in Zurich, where I focus on audits of third-party products, security reviews and consulting. I work with ISO 27001, NIST SP 800-82 and IEC 62443 standards.

Prior to this, I held engineering roles across embedded development and DevOps. At Elsys Design, I developed Linux-based communication software and contributed to bootloader and kernel-level modifications for custom platforms. At Edenred, I supported critical infrastructure through system administration, led cloud migration efforts, and implemented Infrastructure as Code using Ansible.

With a Master’s degree in Cybersecurity and a background in mathematics and systems programming, I bring a pragmatic approach to securing both hardware and software systems across the stack.I am a security engineer with a strong foundation in embedded systems, Linux, and cloud infrastructure.
