We are expanding our Public Sector team and hiring a Systems Engineer to support our Defence and National Security customers.

Our work in this sector spans secure network transformation, SD-WAN for multi-site environments, NGFW and segmentation, SOC and monitoring integration, public and private cloud adoption, and end-to-end security architecture across highly regulated and security-conscious environments. You will work closely with account teams, defence partners, systems integrators and public sector stakeholders to design and validate solutions that improve resilience, reduce risk and support critical national missions.
As a Systems Engineer at Fortinet, you'll be a trusted technical advisor to customers, partners and account teams, working throughout the sales cycle to understand complex requirements, develop secure architectures and demonstrate how Fortinet solutions can address the challenges faced by Defence and National Security organisations.

Support RFI/RFP responses and ensure accurate technical documentation within Salesforce
Act as a trusted technical advisor, providing guidance and mentorship to colleagues and partners and sharing best practices across the wider Systems Engineering organisation
What We're Looking For :
