CoreWeave’s Network Security team ensures network infrastructure is secure, resilient and compliant. Our team partners with engineering, product teams, and partners to build secure network solutions that protect critical infrastructure and continuously improve the security posture to meet the needs of our customers. With our growing reliance on connected technology, the need to keep critical systems secure, reliable, and resilient has never been more important. We are seeking an OT Security Engineer to join our team and play a pivotal role in safeguarding the operational technologies that support our datacenter networks.
About the role:
This position offers a unique opportunity to work at the crossroads of cyber security, operational technology (OT), engineering, and datacenter operations. As the network security engineer responsible for our operational technology networks, your responsibilities will include identifying and evaluating cybersecurity risks, designing and launching pragmatic security solutions, and embedding security controls directly into the operational systems and technologies supporting our infrastructure. You will work with suppliers and third parties in benchmarking their capabilities against expectations and industry standards. You will also lead efforts in partnering with peer security teams and partners in production engineering as you lead continuous improvement of security posture for operational technology network environments and the devices connected.

- Creating an inventory and risk register that can be used as a baseline in understanding near term and long term objectives.
- Partnering with production engineering and business development teams evaluating priorities for risk reduction in current deployments, and risk avoidance by evolving standards for future growth.
- Executing and partnering with other parties in using penetration testing to evaluate effectiveness of existing controls.
- Coordinating with third parties and internal teams in addressing vulnerabilities via mitigation, isolation or other strategies to protect critical infrastructure in these environments.
- Researching industry risks and drive change in operational networks to continuously reduce risk
- Developing and test recovery models and response playbooks to handle compromise scenarios.
- Presenting technical security information to both technical and non-technical audiences, including external partners. Maintain technical documentation, reports, and security tooling with attention to detail.
