About the Role

Stax - Deep Tech Headhunters are partnering with a high-growth international Series A company on a mission to transform the way organisations harness AI for customer support and product operations.

They’re looking for a Senior UI Architect who sits at the intersection of design excellence and engineering. This is a hands-on, systems-level leadership role for someone who doesn’t just ship components—they craft cohesive, elegant, ultra-performant experiences.

You’ll play a defining role in setting the architectural direction for all user-facing surfaces—from fast, reactive dashboards to rich collaborative tools—ensuring interfaces are not only beautiful and intuitive, but also scalable and lightning-fast.

What You’ll Do

• Collaborate with the design team to create and implement design systems.
• Develop atomic and molecule-level UI components.
• Ensure information hierarchy and consistency across the design system.
• Collaborate with global teams to ensure integration with existing systems.

You Might Be a Fit If You Have

• 10+ years of UI engineering experience.
• Proficiency in React, Tailwind, and TypeScript.
• Experience with micro front-end architectures.
• Next.js knowledge is a plus.
• Strong collaboration skills across geographically distributed teams.
• Experience in consumer-grade applications emphasizing high craftsmanship is preferred.

Why This Role?

You’ll be joining a deeply design-led culture, where architecture is about crafting user delight—not just technical scalability. This is an opportunity to shape the front-end foundation of a new category-defining platform at the ground level, in an environment that values velocity, quality, and cross-disciplinary collaboration.

Engineers here don’t operate in silos. They lead from the front—building, mentoring, and pushing boundaries every day. Stax is proud to represent this opportunity. If you’re a UI leader who’s excited by scale, strategy, and AI-powered innovation, we’d love to hear from you. We welcome applicants from all backgrounds.
