About the Role

We are looking for a Senior Blockchain Developer with hands-on experience across blockchain protocols and cross-chain solutions. Your first and most critical task will be the integration of the Ton blockchain into Chainlink CCIP, so experience-or the ability to quickly get up to speed-with Ton, Chainlink, and cross-chain technologies is essential. This is a high-impact role, ideal for someone who thrives in a fast-paced, deeply technical environment. We're seeking someone who can ramp up quickly and deliver immediate value.

Key Responsibilities

  • Lead the integration of Ton blockchain into Chainlink CCIP.
  • Develop, test, and deploy cross-chain bridging solutions.
  • Collaborate with protocol and infrastructure teams to ensure seamless interoperability across chains.
  • Write clean, secure, and maintainable code using TypeScript and Next.js.
  • Stay up-to-date with emerging blockchain technologies like SUI and Canton, and contribute to architectural discussions.

Required Qualifications

  • Must be located in the U.S. or Canada
  • Senior-level experience (5+ years preferred) in blockchain development.
  • Proven expertise with Chainlink, cross-chain bridges, and non-EVM blockchain networks.
  • Strong understanding of decentralized systems and blockchain interoperability.
  • Experience or demonstrated ability to quickly learn Ton blockchain.
  • Proficiency in TypeScript and Next.js.

Nice to Have

  • Experience with emerging protocols such as SUI and Canton.
  • Familiarity with Chainlink CCIP architecture and its extensibility model.
  • Prior work in DeFi, cross-chain DApps, or oracle integration.
Note: If you are not familiar with Ton but are a fast learner with strong fundamentals in blockchain and cross-chain technologies, we still encourage you to apply.
