The Role

We're looking for a highly skilled Senior Web3 Frontend Engineer to join our growing team and take a leading role in building the next generation of decentralized applications and blockchain user experiences.

Your work will help shape how users interact with decentralized finance and the broader MANTRA ecosystem.

• Lead by example — influence architectural direction and help define long-term technical strategy.
• Architect, build, and maintain highly responsive and user-friendly Web3 interfaces.
• Collaborate with designers to deliver pixel-perfect UI with strong UX principles.
• Own the full frontend development lifecycle: from design handoff to production deployment.
