• Familiar with implementing crypto wallets (Cestode and non-Cestode)
• Experience integrating third-party APIs and service providers
• Solid understanding of how blockchain networks operate
• Experience working with WalletConnect is a plus
• Confident working with APIs both as a provider and consumer
• Passionate about crypto and its potential in commerce

What You’ll Be Doing:
• Developing a crypto payments web app using modern technologies
• Building and integrating Cestode and other wallets
• Working across the stack to connect frontend with blockchain logic
• Collaborating on architecture and product direction
• Managing integrations with service providers and crypto networks

How to Apply:
If you’re a developer with solid blockchain knowledge and a passion for bringing crypto into the real world — this is your opportunity to be part of something truly innovative.

Apply now, and I (Daniel Wilson-Meghie) will be in touch to walk you through the next steps.
