About the Role

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

They’re looking for a Senior UI Architect who operates at the intersection of design excellence and engineering. This is a hands-on, systems-level leadership role for someone who crafts cohesive, elegant, and high-performance user experiences, not just ships components.

You’ll play a key role in defining the architectural direction for all user-facing surfaces—from fast, reactive dashboards to rich collaborative tools—ensuring interfaces are beautiful, intuitive, 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 system integration.

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 distributed teams.
• Experience in consumer-grade applications emphasizing craftsmanship is preferred.

Why This Role?

You’ll join a deeply design-led culture where architecture focuses on crafting user delight, not just scalability. This is an opportunity to shape the front-end foundation of a new platform at its ground level, in an environment that values velocity, quality, and collaboration.

Engineers here lead from the front—building, mentoring, and pushing boundaries daily. Stax is proud to present this opportunity. If you’re a UI leader excited by scale, strategy, and AI innovation, we’d love to hear from you. We welcome applicants from all backgrounds.
