UX Designer, Device

About the Company:

World is building a real human network designed to accelerate people in the age of AI. As bots and autonomous agents reshape the internet, people, institutions, and applications need a trusted way to confirm who is a real human while preserving privacy. Our products make this possible: the Orb verifies real people, World ID proves it privately, and World App enables and distributes the new applications made possible by this technology. Together, they form a new layer for AI internet.

We’re one of the fastest-growing networks in tech. More than 17 million people across 160 countries have verified with World ID, and we complete over 350,000 verifications each week. World App is already among the most used wallets globally. Developers are integrating World ID to build safer online experiences and create spaces where real people can participate, earn, and be recognized in ways AI simply can’t replicate.

World was founded in 2019 and launched globally in 2023. We are more than 400 people across hardware, software, AI, cryptography, mobile engineering, and global operations. Our teams come from OpenAI, Tesla, SpaceX, Apple, Google, Stripe, Meta, Coinbase, Palantir and MIT Media Lab. We’re backed by leading investors, including a16z, Khosla Ventures, Bain Capital Crypto, Blockchain Capital, Variant, Tiger Global, and Coinbase Ventures, as well as prominent operators and founders across fintech and AI.

World has been featured on the cover of TIME Magazine, highlighted in Fast Company’s Next 5 in Fintech, and explored in a Bloomberg deep dive. The New York Times, Bankless and TechCrunch have all recognized our progress in identity, cryptography, AI, and global-scale hardware deployment. Our leadership is also named to the Time AI 100.

  • Translate insights into product requirements, prototypes, service flows, and design guidelines.

• New Product Introduction (NPI)

  • Lead UX development from concept through launch for new hardware and software products.

  • Partner with engineering and manufacturing teams to ensure intent is preserved through build stages.

• In-Field Sustaining

  • Monitor the performance of the end-to-end experience in real-world deployments.

  • Drive iterative improvements to flows, instructions, cues, and physical artifacts based on data and field feedback.

What You’ll Bring

7+ years of UX, service design, or multi-modal experience design, ideally with hardware + software products.

• A strong portfolio demonstrating end-to-end systems thinking and multi-touchpoint experience design.

• Expertise in designing experiences that blend physical, digital, and sensory inputs.

• Hands-on prototyping skills (Figma, motion, audio, physical mockups).

• Ability to lead research, synthesize complex data, and drive alignment across cross-functional teams.

• Experience working closely with hardware engineering, ID, firmware, and product teams is a plus.

• Comfortable working in a fast-paced, iterative environment with high ambiguity.
