Defi
Miami, FL Full Time
POSTED ON 3/3/2025
AVAILABLE BEFORE 8/25/2025
Role Overview

As a Full Stack Developer, you will be responsible for end-to-end development—from designing robust back-end architectures to implementing sleek, high-performing front-end interfaces. You’ll collaborate with cross-functional teams (product, design, DevOps) to bring secure and scalable features to our growing user base.

Key Responsibilities

  • Build & Maintain: Develop new features on both front-end and back-end, ensuring clean, maintainable code.
  • Integration: Work closely with external APIs/services, particularly in Web3/DeFi contexts, to enable real-time data and transaction functionalities.
  • Performance & Security: Optimize for speed and handle potential high-traffic scenarios while maintaining strict security standards.
  • Collaboration: Participate in code reviews, architectural discussions, and mentorship for junior developers.
  • Innovation: Stay current with evolving blockchain and Web3 trends to propose and implement best practices.
What We’re Looking For
  • 3 years of software development experience (full stack or front-end/back-end combined).
  • Expertise with JavaScript/TypeScript frameworks (Node.js, React, or similar).
  • Experience working in the crypto/DeFi domain (smart contracts, on-chain data, wallet integrations, etc.)—Solana experience is a huge plus.
  • Proficient in RESTful API development; familiarity with WebSocket or real-time data streaming is desirable.
  • Strong Knowledge of security best practices and user authentication flows (especially in a non-custodial or Web3 context).
  • Comfortable with agile methodologies, CI/CD pipelines, and Git-based workflows.
  • Problem-Solving Mindset: able to handle complex challenges, propose elegant solutions, and adapt quickly to shifting requirements.
Nice-to-Have Skills
  • Familiarity with Solana or other L1 blockchains.
  • Smart Contract development experience (Rust, Solidity, or similar).
  • Knowledge of Next.js, Vue, or other modern front-end frameworks.
  • DevOps or cloud infrastructure (AWS, GCP) for scalable deployments.
  • Experience building or integrating subscription-based or advanced data-driven features.
How to Apply
  • Send your CV/LinkedIn profile and GitHub or portfolio links.
  • Highlight relevant Web3 or crypto projects you’ve built or contributed to.
  • Include a brief note on why you’re excited about this role and how your experience aligns.
