GRAIL is seeking a Network Engineer to join our Platform Engineering organization. Our team designs, builds, and operates the enterprise networking infrastructure that powers GRAIL's laboratories, data centers, cloud platforms, and corporate environments. We are responsible for delivering highly available, secure, and scalable network services across on-premises infrastructure and AWS.

In this role, you will be responsible for engineering, operating, and continuously improving GRAIL's hybrid network infrastructure, including campus, laboratory, data center, WAN, cloud networking, and security platforms. You will work with Juniper and Aruba switching and routing, Palo Alto firewalls, AWS networking, VPN technologies, monitoring platforms, and infrastructure automation to build reliable, scalable, and secure networking solutions.

This is an engineering-focused role rather than a traditional network operations position. We are looking for someone who enjoys designing scalable infrastructure, automating repetitive tasks, improving platform reliability, and partnering across engineering teams to deliver secure and resilient networking services.

You will collaborate closely with Platform Engineering, Cloud Engineering, Security, Infrastructure, and application teams to support business-critical services while driving operational excellence through automation, observability, and modern networking practices.

This role is based in Durham, North Carolina (RTP) and requires regular on-site presence to support laboratory and data center infrastructure. This position requires on call and overtime flexibility.
