IMPORTANT: Candidates must already be based in the UK with full right to work.

Join Fortinet, a global cybersecurity leader with over two decades of innovation, as we continue to shape the future of secure digital transformation. Our mission is to protect people, devices and data everywhere and we're looking for a talented Systems Engineer to support our Financial Services & Insurance customers across the UK.

As organisations across the FSI sector continue to modernise their infrastructure, strengthen cyber resilience, and navigate an increasingly complex threat landscape, we're looking for a Systems Engineer who can act as a trusted technical advisor to some of the UK's largest and most security-conscious organisations.

You'll work alongside our sales teams to design and position Fortinet's industry-leading security solutions, helping customers address challenges around hybrid cloud, Zero Trust, secure networking, regulatory compliance, operational resilience, and digital transformation.

Our solutions span technologies including multi-tenant security architectures, SOC technologies, cloud security, SASE, SD-WAN, Zero Trust, and broader cybersecurity architectures designed for large, complex enterprise environments.

As a Systems Engineer at Fortinet, you'll be a trusted technical advisor to customers and partners, working closely with account teams to drive adoption of Fortinet's cybersecurity platform. You'll play a key role throughout the sales cycle, from discovery and solution design through proof-of-concept and deployment, helping customers solve complex security challenges with confidence.

What You'll Do

  • Lead technical engagements across the sales lifecycle, including discovery workshops, solution design, presentations, and proof-of-concepts.
  • Translate customer business and technical requirements into scalable Fortinet architectures.
  • Deliver compelling product demonstrations, architecture workshops, and executive-level whiteboarding sessions.
  • Partner closely with customers, channel partners, and internal teams to develop security strategies aligned with business and regulatory requirements.
  • Maintain deep expertise across Fortinet's portfolio, cybersecurity trends, emerging threats, and technologies relevant to the FSI sector.
  • Support RFI/RFP responses and maintain accurate technical documentation within Salesforce.
  • Act as a trusted technical advisor and mentor to colleagues and partners.

What We're Looking For

We're looking for a technically strong, customer-focused Systems Engineer who enjoys solving complex security challenges within large enterprise environments.

You may be a great fit if you have:

  • Experience in a pre-sales engineering, technical consulting, or customer-facing technical role.
  • Experience working with Financial Services or Insurance customers, or other highly regulated enterprise environments.
  • Strong knowledge of cybersecurity technologies including Network Security, SASE, SD-WAN, Zero Trust, SOC technologies, Cloud Security, and Secure Access.
  • Experience designing solutions for complex enterprise environments with multiple stakeholders.
  • Excellent communication and presentation skills, with the ability to engage both technical teams and senior business stakeholders.
  • A collaborative mindset with the ability to build trusted long-term customer relationships.
  • Industry certifications such as NSE, CISSP, CCNP or equivalent are advantageous.

You'll join a collaborative team with access to continuous learning, career development, and a Total Rewards package that supports your health, wellbeing, and financial future.
