Job Description

Biconomy empowers Web3 developers to build seamless, user-friendly dApps that work effortlessly across multiple blockchains. Our battle-tested modular account and execution stack eliminates traditional UX friction points, helping projects accelerate user adoption while reducing development costs. By processing over 50 million transactions across the 300+ dApps we've served, we're powering the future of onchain economies.

The Role: Innovating at the Intersection of AI and DeFi

We’re now building Nomy - an AI-powered crypto assistant that helps users intuitively interact with onchain operations, manage portfolios, and simplify the entire Web3 experience. As we bring this product to life, we’re looking for a Mobile Developer to join our AI team and lead the development of our mobile apps. This is a unique opportunity to build a product at the intersection of AI, crypto, and fintech, and craft seamless mobile experiences that abstract away the complexity of Web3 for everyday users.

What Will You Be Doing?

  • Design, develop, and maintain mobile applications for iOS and Android using React Native or native technologies (Swift/Kotlin).
  • Collaborate closely with AI/ML engineers, backend developers, and product designers to bring Nomy’s features to life.
  • Build sleek, performant, and secure mobile interfaces that simplify complex blockchain interactions.
  • Integrate wallet functionality, real-time onchain data, and LLM-driven user interactions into a cohesive mobile experience.
  • Ensure high code quality through testing, code reviews, and best practices.
  • Own end-to-end mobile features - from prototyping and development to deployment and iteration.
  • Continuously improve the user experience based on user feedback, analytics, and emerging best practices.

Requirements

  • Familiarity with mobile performance optimization and secure data handling.
  • Experience working with APIs (REST, GraphQL) and state management libraries.
  • Strong communication and collaboration skills in cross-functional teams.
  • Self-starter mindset with the ability to thrive in a fast-paced, remote-first environment.

Nice to Have

  • Experience integrating crypto wallets or Web3 SDKs (ethers.js, WalletConnect, etc).
  • Exposure to AI-powered applications, especially LLM-based assistants or chat UIs.
  • Understanding of blockchain fundamentals: EVM, smart contracts, gas fees, DeFi interactions.
  • Previous work on fintech or security-sensitive mobile applications.

What We Offer

  • Flexible Working Hours: Enjoy autonomy over your schedule.
  • Generous Vacation Policy: 25 days vacation per year plus public holidays
  • Competitive Salary: With regular performance reviews.
  • Token Allocation: Be rewarded with tokens as part of our compensation package.
