Roles & Responsibilities

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

Attributes?

What You Bring

• 5+ years of experience in backend engineering (preferably with Node.js or TypeScript)

• Strong grasp of distributed systems, workflow orchestration, and event-driven architecture

• Deep experience with PostgreSQL, and confidence with ORM layers like Prisma

• 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

• Product-minded: you care about the "why," not just the "how"

• Comfortable navigating early-stage uncertainty, while setting high engineering standards

Bonus

• Experience leading teams or projects in fintech or crypto infrastructure

• Familiarity with FX trading, liquidity networks, or regulatory frameworks

• Contributions to open-source in the AI, blockchain, or payment domains

Why Xweave

• We're shaping the future of programmable global finance

• You'll work at the frontier of AI agents and crypto payments

• Early opportunity to shape architecture, hiring, and technical culture

• Backed by strong infrastructure and fintech partners
