🚀 Build real-world crypto payments used at global scale

We're looking for a backend-focused software engineer with blockchain experience to help build and scale next-generation payments infrastructure. This is a hands-on role for someone who wants to work close to the product, touch real users, and ship systems that operate at serious scale.

Location

• Strong preference for New York City
• Open to remote (US or global) for exceptional candidates with strong experience and solid tenure
  
  

What You'll Be Doing

• Play a key role in shaping the technical and product roadmap
• Build and scale backend services that interact with blockchain infrastructure
• Work directly with smart contracts across multiple chains
• Develop and support new smart contracts and blockchain integrations
• Help scale on-chain infrastructure to millions of users globally
• Ship new features quickly in a fast-moving environment
• Influence architectural decisions in a rapidly evolving product
  
  

This role is ideal for someone who enjoys ownership, speed, and solving real problems at the intersection of payments, fintech, and crypto.

Why This Role Is Different

• You'll be building real-world crypto infrastructure, not side experiments
• Flat, open culture - engineers influence the roadmap
• High ownership and autonomy
• Backed by top-tier investors in fintech and crypto
• Global impact from day one
  
  

Requirements

What We're Looking For

• 2-10+ years of professional engineering experience
• Strong experience with Node.js and modern backend technologies
• Hands-on experience interacting with blockchains and smart contracts
• A backend engineer with real blockchain exposure (not just interest)
• Crypto-curious at minimum - crypto-native is a plus
• Comfortable working in lean, fast-paced teams
  
  

Nice to have (not required):

• Fintech experience (neobanks, card issuing, payments infrastructure)
