About The Role

We're seeking a Senior Blockchain Engineer/Blockchain Architect with extensive experience developing smart contracts on Solana (Rust) or Ethereum/EVM-compatible chains (Solidity), who is passionate about applying blockchain technology to innovative financial products in the real world.

This is a hands-on engineering role with outsized ownership: you’ll shape system architecture, write secure and scalable code, and work closely with product and business teams to bring new ideas to life. It’s ideal for someone who loves building but also thinks like a product owner — connecting technical decisions to user experience and business outcomes.

What you’ll do

• Design and deploy production-grade smart contracts.
• Build secure, scalable blockchain systems for asset management and financial use cases.
• Develop backend services (Node.js/TypeScript) to support on-chain functionality.
• Work with product and business teams to turn ideas into clear, secure execution.
• Contribute to architecture decisions, reviews, and audits.
  
  

What We’re Looking For

• 5+ years in software development.
• 2+ years building smart contracts on Solana (Rust) or Ethereum (Solidity), with strong expertise in at least one and open to developing in a multi-chain environment.
• Solid backend development experience (Node.js/TypeScript).
• Strong product sense and ability to take end-to-end ownership.
• Clear communication, collaboration, and commitment to code quality.
  
  

Nice to Have

• Experience with DeFi protocols, cross-chain integrations, or account abstraction.
• Knowledge of finance systems or payments products.
• Startup experience where you’ve worn multiple hats.
