Our mission is to protect people, devices and data everywhere, and we’re looking for a talented Systems Engineer to join our Strategic and GSI team in the UK.

As a Systems Engineer at Fortinet, you’ll be a trusted technical adviser to our GSI partners and their customers. You’ll work closely with GSI Account Managers to drive adoption of Fortinet’s industry-leading security solutions, and play a key role throughout the sales cycle, from discovery and design to proof-of-concept and deployment, helping customers solve complex security challenges with confidence. The work covers multi-tenant security architectures, SOC technologies, cloud security, SASE, SD-WAN and broader cybersecurity design for service delivery.

What You’ll Do

• Lead technical engagements across the sales lifecycle on GSI-led opportunities, including discovery, solution design, presentations and PoCs

• Drive partner enablement, building the technical capability of GSI teams to position, design and deliver Fortinet solutions
• Build strong technical relationships with strategic GSIs to accelerate opportunity conversion
• Deliver engaging product demonstrations, architecture workshops and whiteboarding sessions
• Work cross-functionally with GSI partners, customers and internal teams to ensure successful solution delivery
• Maintain deep expertise across Fortinet’s portfolio, industry trends and emerging threats
• Support RFI/RFP responses and ensure accurate documentation in Salesforce
• Act as a technical mentor and knowledge resource for partners and colleagues

What We’re Looking For
We’re looking for technically skilled, customer-focused professionals who thrive in dynamic environments and enjoy solving complex challenges. You may be a great fit if you have:

• Experience in a pre-sales engineering, technical consulting or customer-facing technical role, ideally working with or within GSIs or large technology partners
• Knowledge of cybersecurity technologies such as Network Security, SASE, SD-WAN, Zero Trust, SOC tools and Cloud
• Exposure to AI, cloud or data centre infrastructure projects (desirable)
• Strong communication and presentation skills, with the ability to engage both technical and non-technical audiences
