Principal Product Designer

Lead the design of the next-generation digital Network-as-a-Service experience and create high-fidelity prototypes for customer validation. Collaborate with cross-functional teams to ensure clarity and quality in the product vision.

Responsibilities

• Work with the CDO and Product Leaders to visualise and prototype the future-state digital customer experience.
• Translate broad concepts into tangible, high-fidelity, interactive prototypes that bring clarity and direction.
• Use AI tools, no-code/low-code platforms, and modern prototyping techniques to work at speed.
• Design flows, interactions, and UI components for multi-step workflows (discovery, ordering, provisioning, configuration, support).
• Build experience consistency across underlay, overlay, and in-life services.
• Define and uphold quality standards for experience and usability.
• Collaborate with Product Managers in customer discovery and usability testing.
• Validate ideas early with real users to de-risk investment and iterate quickly.
• Be a design authority and thought partner to PMs, Engineers, and Executives.
• Help shape our design culture, standards, and hiring roadmap.
• Prepare for future scale: contribute to design systems and foundations that support STO-based product teams.

Requirements

• 10+ years of product design experience, including experience designing platforms, internal tools, or complex enterprise systems.
• Experience working in scaled, multi-team environments (you’ve influenced beyond your squad).
• Strong portfolio of work showing concept-to-delivery process and product impact.
• High comfort with rapid prototyping tools (e.g. Figma, Framer, Webflow, AI tools, etc.).
• Strong product sense—you don’t just accept the brief; you improve it.
• Confidence in ambiguous, fast-changing environments. You’re used to bringing clarity where there isn’t much.
• The ability to see the system, not just the screen—designing experiences that scale across products, geographies, and customers.
