Lead UX Designer

Lead UX Designer

Location: Remote
Type: Full-time

Open Serv is an early-stage startup building an AI-agent platform for Web3 and beyond. We’re fast, scrappy, and ambitious - our small team is shipping products at breakneck speed, constantly iterating and experimenting. If you thrive in ambiguity, can create clarity out of chaos, and love shaping product experiences from the ground up, this is the place for you.

We’re looking for a Lead UX Designer to own the end-to-end design of our products. You’ll be the design voice at the table, working closely with product and engineering to shape strategy, craft interfaces, and build a foundation for scalable design practices. This isn’t a role for someone who needs everything figured out upfront - you’ll need to bring structure, influence, and creativity to a high-growth environment.

• Lead UX strategy and execution across our product suite.

• Partner with Product and Engineering to define problem spaces and translate them into elegant, user-centred solutions.

• Conduct discovery and usability research to ground design decisions in real user needs.
  Create end-to-end flows, wireframes, prototypes, and high-fidelity UI.

• Evolve the design system to keep things consistent as we scale.

• Advocate for design thinking across the company, influencing stakeholders in a non-design-led environment.

• Balance big-picture vision with scrappy delivery - knowing when to zoom out and when to ship.

• 6+ years’ experience in UX/product design, with at least 2 years in a lead role.

• Strong portfolio demonstrating product thinking, UX craft, and polished visual design.

• Ability to thrive in ambiguity: you’re comfortable creating structure.

• Experience running end-to-end research and usability testing.

• Strong communicator who can influence founders, PMs, and engineers.

• Proficiency in Figma (bonus if you’ve helped wrangle multi-product files before).

• Entrepreneurial mindset—self-starter, pragmatic, and happy to get your hands dirty.

• Experience designing for AI, Web3, or other emerging tech.

• Startup or scale-up experience where you’ve built design from the ground up.

• Comfort with rapid prototyping tools

• Understanding of front-end development constraints (HTML/CSS, React).

• Interest in brand design, storytelling, or other creative disciplines.

• Shape the design culture and product experience of a company from the early days.

• Work on cutting-edge AI + Web3 products with global reach.

• Fully remote, flexible working.

• A scrappy, collaborative team that moves fast and breaks things (on purpose).
