Coinspaid Dev is the engineering brand behind the technology, infrastructure, and R&D expertise built within Coinspaid. With more than 120 engineers and over 11 years of industry experience, Coinspaid Dev brings together software engineering, infrastructure, security and R&D teams with experience building distributed systems and blockchain infrastructure operating across more than 20 blockchain networks.

Coinspaid Dev emerges as an independent engineering brand with a straightforward mission: to advance blockchain infrastructure engineering and contribute practical expertise back to the industry. The structure is new. The experience behind it is not.

This is not a feature-team role focused on shipping isolated product functionality. You will work on a shared UI platform that defines how all company products look, feel, and scale. Your success will be measured by the quality, consistency, and adoption of the UI Kit and design system across teams, with a strong focus on long-term architecture, developer experience, and close collaboration with product design. If you’re looking for deep ownership and company-wide impact, this role is a great fit, however, if you prefer working within a single product team delivering features, it likely isn’t.

  • Experience working closely with designers (Figma, design handoff, design tokens synchronization)
  • Passion for UI quality, consistency, and reusable component development
  • Experience integrating a shared UI Kit into multiple applications and teams

    • Quality, ownership & engineering mindset

  • Ability to work independently and solve complex problems
