Backend Engineer
Xuman.AI
Job Description
Every solopreneur delivering a human-led service today is duct-taping five tools together just to get paid. Xuman.AI is replacing all of them. One AI-native operating system where content becomes discovery, discovery becomes booking, and booking becomes a relationship that compounds.
We are live on both app stores with a real product, real architecture, and hard problems left to solve. If you are looking for a place where you can build fast, use AI as a force multiplier, and see your work in production within days - keep reading. What you will own: - The entire backend of a live consumer product - NestJS monorepo, microservices architecture, the full server-side stack - Database design, migrations, and query optimization (Prisma + PostgreSQL) - Infrastructure and deployments (Docker, Azure Container Apps, CI/CD) - Real-time systems (WebSocket, Redis pub/sub), caching, and payment integrations - API design, stability, and production reliability - Backend for new features shipping on a weekly cadence - Integration layer between the mobile app, AI services, and data systems What we are looking for: - 1-5 years of experience with TypeScript and Node.js - Strong experience with NestJS or similar structured backend frameworks - PostgreSQL and Prisma (or equivalent ORM) - schema design, migrations, query optimization - Docker and containerized deployments - Understanding of event-driven architecture and pub/sub patterns - Comfortable debugging production systems through logs, traces, and metrics - You use AI tools (Claude, Copilot, ChatGPT) daily to write, debug, and ship faster.
Not optional - this is how we work. - Active builder - you maintain side projects, contribute to open source, or ship things outside of work - Able to work autonomously and make sound technical decisions with minimal direction Why join Xuman.AI: You are joining the foundation. Your decisions become the architecture. Equity discussion starts at 90 days based on impact - and at this stage, equity actually means something.
Direct access to the founder, direct impact on a product that people already use. How to apply: We do not review resumes. We review how you think.
Record a 5-7 minute video (YouTube unlisted or Google Drive) and email the link to [email protected] with the subject "Backend Engineer - (Your Name)". Part A (2 min): Who are you? What have you built that you are proud of?
What did you learn from something that failed? Why does building backend systems excite you? Part B (3-5 min): Download the app (App Store / Google Play) and explore xuman.ai.
Then answer on camera: (1) What is the biggest backend challenge in this product? (2) What would you prioritize in your first 30 days? (3) What questions would you ask the founder before writing any code? Also include: a link to your GitHub profile or a project you have built (not a tutorial clone). No video = no review.
We review every submission personally within 48 hours.
