At goML, we design and build cutting-edge Generative AI, AI/ML, Data Engineering, and Web3 solutions that help businesses unlock the full potential of emerging technologies, drive intelligent automation, and build secure, scalable digital experiences. Our mission is to bridge the gap between state-of-the-art technology and real-world enterprise applications—helping organizations innovate faster, make smarter decisions, and scale solutions seamlessly.

We’re looking for a Blockchain Developer with strong hands-on experience in blockchain protocols, smart contracts, Web3 integrations, wallets, and blockchain data. In this role, you’ll help design and build secure, scalable blockchain solutions and integrations across wallets, exchanges, custody platforms, and blockchain networks. If you enjoy working at the intersection of blockchain, crypto, APIs, security, and enterprise applications, we’d love to hear from you!

Why You? Why Now?

As enterprises increasingly adopt digital assets, blockchain infrastructure, and Web3 technologies, there is growing demand for engineers who can build reliable and secure blockchain applications.

This role is ideal for someone who can define the blockchain technology stack, evaluate blockchain platforms, establish the development and infrastructure architecture, set up blockchain networks and nodes, develop smart contracts and Web3 applications, and build successful solutions for production.

The role will span multiple blockchain use cases and ecosystems, including digital assets, DeFi, tokenization, cross-border payments, decentralized identity, supply chain, blockchain analytics, wallets, custody, exchanges, and enterprise blockchain solutions.

If you enjoy researching emerging blockchain technologies, making architecture decisions, building things from scratch, and turning blockchain concepts into production-grade systems, we’d love to hear from you.
