DevOps engineer in OT security

Are you ready to automate the security of a global manufacturer’s plants? Deploy and run Claroty CTD and Zscaler Secure Remote Access across industrial sites, hands-on, fully remote.

• Build integrations through the APIs of both platforms and manage access policies as code, with version control, review and rollback
• Support the day-to-day operation of the platforms across international plants, including monitoring, health checks, updates and troubleshooting
• Work with IT and OT teams on network segmentation and secure remote access to plant networks, including vendor and third-party access
• Connect the platforms to the wider security landscape, such as SIEM, ticketing and monitoring tools
• Write runbooks, standards and documentation so that operations can be handed over and scaled to new sites
• Help the client’s teams improve how security platforms are delivered, with a focus on repeatability, reliability and low operational risk in production environments
