What is Xweave?
Xweave is building the orchestration engine for the future of cross-border money movement — combining the best of blockchain, stablecoins, and AI. Our platform integrates crypto rails with traditional financial systems to deliver seamless, programmable, and intelligent fund transfers across the globe. We are a deeply technical team working at the intersection of blockchain infrastructure, AI agents, and money transfer compliance.
What is the role?
We're looking for a founding Software Engineer (Lead/Senior) to join our team.
• Design, implement, and evolve our core orchestration engine using Node.js, Prisma, and PostgreSQL
• Lead the architecture of distributed Temporal workflows to handle payment routing, retries, settlements, and audits
• Drive the development of our internal MCP service, used for training and fine-tuning models that detect routing paths and optimize FX/corridor selection
• Architect and build LLM-powered AI agents using LangChain to autonomously search, analyze, and act on cross-border opportunities
• Collaborate on the full lifecycle of AI models — from data labeling and training to inference, evaluation, and feedback integration
• Maintain and evolve our codebase to ensure clean interfaces and smooth integration of new partners into our network
• Mentor junior engineers and guide code quality, security practices, and observability standards
• Work closely with the founding team to shape product direction, infrastructure scale-up, and integration with blockchain and financial partners

• Hands-on experience with Temporal.io or similar workflow engines
• Familiarity with LLM concepts, and experience building agent-style systems using LangChain or similar tools
• Exposure to blockchain primitives, stablecoins, and VASP/payment rails integration
