Senior Product Designer

QuantumGate is a startup within VentureOne, supported by the Advanced Technology Research Council (ATRC) and its research arm, the Technology Innovation Institute (TII). We specialize in developing and commercializing advanced post-quantum cryptographic solutions, with a mission to secure enterprise digital environments through cutting-edge protocols and applications that tackle the challenges of the post-quantum era.

We’re looking for a Senior Product Designer with strong experience designing for products that rely on advanced, multi-platform design systems. You’ll play a key role in shaping user experiences end-to-end while also strengthening and evolving our design system. This opportunity is a great fit if you’re a builder at heart—someone who thrives in product complexity, can work across platforms, and knows how to balance immediate design needs with long-term system health.

Responsibilities

• Design thoughtful, user-centered experiences across web and mobile platforms
• Leverage and extend our design system to deliver consistent, scalable, and accessible solutions
• Collaborate with engineers to ensure designs are implemented with quality and fidelity
• Contribute new components, tokens, and patterns back into the design system, with clear documentation
• Partner with product managers and stakeholders to align design solutions with business and user goals
• Provide feedback and mentorship to designers, raising the quality of design across the team
• Advocate for accessibility, usability, and scalable design practices in every project

Requirements

• 5+ years of experience in product design or UX/UI design, with a track record of delivering digital products
• Proficiency with Figma (components, variants, tokens, and library management)
• Experience designing across multiple platforms (responsive web, iOS, Android)
• Familiarity with front-end concepts (HTML, CSS, component frameworks) and a collaborative approach with engineers
• Strong problem-solving skills with the ability to untangle complexity and create clarity
• Excellent communication and documentation skills, with the ability to influence peers and stakeholders
• Solid understanding of accessibility standards (WCAG) and how to apply them

Nice to have

• Experience contributing to or evolving a design system at scale
• Exposure to tools like Storybook, Zeroheight, or Tokens Studio
• Prior experience in a startup or high-growth product environment
• Systems thinking mindset—balancing detail-level design craft with holistic consistency

Why Join Us?

We value builders who thrive in complexity. Here you’ll shape product experiences that matter while also helping evolve the design system that powers them. Your work will directly influence how our teams ship products with quality and consistency at scale.
