About Unlimit Founded in 2009, Unlimit is a global fintech company with 16 offices worldwide and more than 500 employees, offering a comprehensive portfolio of financial services—from acquiring (payment processing) to banking-as-a-service. Our mission is to be “ready for tomorrow,” providing our customers with stability in the ever-changing financial landscape and empowering them to seize opportunities ahead of the curve. While others observe, our customers take the lead. We’re looking for a forward-thinking, results-driven Blockchain Application Engineer to help shape the future of payments at the intersection of blockchain innovation and AI-powered development. In this role, AI isn’t an add-on—it’s embedded in every stage of the engineering process, from architecture and coding to testing and optimization, with copilots and agents acting as true partners to accelerate delivery. You’ll design and build applications that bridge traditional payment rails with decentralized protocols, ensuring seamless and reliable transaction flows, while working with a modern tech stack that includes Go, microservices, and AI-driven automation. Collaborating with product, compliance, and infrastructure teams, you’ll create secure, scalable, and industry-leading financial products in a fast-paced environment where innovation is constant, delivery speed is amplified by AI, and your work directly shapes how money moves around the world. What You Will Be Doing From day one, you’ll be building at the frontier where blockchain innovation meets next-generation payment infrastructure. AI won’t just be a tool in your toolkit—it will be at the very core of how you design, develop, and deliver. You’ll work alongside a team that treats AI agents and copilots as integral members of the engineering squad, accelerating everything from architecture planning to deployment.   One week, you might be architecting a bridge between a traditional payment processor and a blockchain protocol, letting funds move seamlessly across rails. The next, you could be using AI-assisted code generation to spin up and test microservices in hours instead of days, or leveraging AI-driven analytics to fine-tune transaction throughput in real t ime. You’ll dive deep into blockchain frameworks, experiment with new smart contract patterns, and continuously fold AI automation into the development lifecycle—cutting down feedback loops and letting you focus on the high-impact decisions. Collaboration will be constant, whether you’re translating complex compliance requirements into technical solutions or iterating with the product team to launch features that push the boundaries of what’s possible in payments. Here, AI isn’t a buzzword—it’s our delivery engine. It enables you to spend less time on repetitive tasks and more time on the creative problem-solving that shapes the future of how money moves.
