Senior Product Designer, UX Systems

About VaultN

VaultN is building the games industry’s fastest-growing digital distribution platform, powering many of the world’s leading publishers. Our commercial infrastructure connects distribution, payments, marketing, and data- unifying a long-fragmented industry through technology, automation, and intelligence.

Backed by global investors including Sony Innovation Fund and London Venture Partners, VaultN is at the stage where the people who join today will shape how games are sold and distributed worldwide for years to come.

The next chapter needs real design maturity. You are joining not to maintain what exists, but to define the UX architecture, standards, and governance that let Product, Engineering, and our AI tooling build coherent, on-brand experiences at speed. We’re looking for a next-generation UX designer who is also strong in UI, systems-minded, and genuinely understands our platform - someone who can turn ideas into fast, high-fidelity prototypes, test them with our industry-leading clients, and iterate quickly while cleaning up our existing UX patterns.

Role Overview

VaultN is moving Design upstream, away from producing bespoke UI feature-by-feature and toward owning UX architecture and governance. AI-assisted prototyping and engineering now let Product and Engineering move from requirements to working software very quickly; the remaining bottleneck is UX decision-making and alignment. In this role, you’ll own the UX principles, interaction standards, and design-system governance that let Product, Engineering, and our AI tooling build coherent, on-brand experiences with less bespoke design work required.

You’ll work upstream in the product process, bringing UX thinking into product definition early, defining reusable interaction patterns, and reviewing AI-generated prototypes and shipped features for usability and consistency. This is a senior, systems-level role: expect to spend some time producing individual Figma designs and more time setting the standards, documentation, and guardrails that make good UX the default output of a much faster product process.

Key Responsibilities:

• Own UX principles and interaction standards across the product.
• Lead information architecture and design for complex workflows.
• Govern the design system, keeping it consistent and scalable as the product grows.
• Define and maintain reusable UX patterns and rules for common product scenarios, such as forms, tables, modals, and permissions.
• Provide early UX input during product definition, shaping requirements before prototyping begins.
• Set and uphold accessibility and usability standards.
• Review AI-generated prototypes for UX quality and consistency with established patterns.
• Conduct design QA on implemented functionality to ensure it matches intended UI/UX.
• Run user validation research where appropriate to test and refine design decisions.
• Document UX decisions and rationale so they can be reused by Product, Engineering, and our AI tooling.

Qualifications:

• Demonstrable experience as a senior Product Designer or UX Designer, ideally in a fast-moving SaaS, Fintech, or transactional business.
• Strong systems thinking, with proven experience defining and governing design systems, interaction standards, and reusable UX patterns rather than focusing primarily on UI production.
• Comfortable challenging Product on workflows and requirements, with the confidence to push back when something doesn’t serve the user.
• Ability to work directly and closely with Engineering, with a solid understanding of…
