Senior UX / UI Product Designer - SaaS and AI

Job description

Senior UX/UI Product Designer

Office-based in Moorgate, London - 4 days per week, with one flexible day

The Fortinet data security team helps global customers protect their intellectual property and sensitive data through a unified solution for data loss prevention, insider risk management, and Shadow AI governance that integrates with Fortinet’s Security Fabric.

As a Senior UX/UI Designer, you will collect and translate user insights into efficient workflows, UX, and UI designs for cybersecurity professionals performing complex tasks. The UX team plays a crucial role within the product and engineering organisation — gathering insights, translating business requirements, advocating for users, and bringing our experiences to life through intuitive interfaces.

This is a collaboration-centric role that works closely with colleagues across product, engineering, and customer success. It also offers a genuine opportunity to help shape the design practice itself — building out standards, systems, and research foundations, and championing the value of strong UX/UI skills across the organisation.

Core Responsibilities
• Lead the end-to-end design process — discovery research, problem framing, ideation, cocreation, and usability testing — across all fidelity levels, from rough concepts and wireframes to high-fidelity prototypes. 
• Conduct user research and validation activities that support evidence-based decision making, drawing on both generative and evaluative methods. 
• Synthesize findings into clear, actionable insights and communicate them to stakeholders through reports, journey maps, and opportunity frameworks. Advocate for users in cross functional discussions, helping product managers and engineers make evidence-based decisions and driving alignment among participants. 
• Partner with product management and engineering to translate product initiatives into user centered solutions, helping identify user needs, risks, and opportunities throughout the design process.
• Drive user-centered design, consistency, and usability across teams; contribute to and expand our design library and system, and define research best practices for the team. 
• Drive multiple initiatives across varying scopes, adapting the depth of research to time and resource constraints — knowing when a quick, informal test is enough and when a deeper study is warranted.

Role Requirements
• Bachelor’s degree in Design, Human-Computer Interaction, Computer Science, or a related field.
• A proactive self-starter with proven experience leading design projects of varying scale, comfortable with ambiguity, and driving work forward with user-centered design.
• Excellent interaction and visual design skills, supported by a portfolio of end-to-end projects.
• Fluent across generative and evaluative research methods, able to scope research appropriately to the time and resources available, and to maintain a research repository and best practices for the team.
• Strong communication and presentation skills — able to listen, proactively address feedback, and represent and advocate for users and UX in an engineering-centric organisation.
• Excellent collaboration with multidisciplinary teams — product management, engineering, customer success, and users.
• Focused on customer and end-user personas, using data to inform design options and decisions.
• Experienced with standard UX design (Figma, Sketch, Framer, Storybook) and product analytics tools (Pendo, Amplitude) to support data-driven design.
